Welcome to This Week in OpenNMS for Friday the 13th. It’s yet again time to take a look at what’s been going on in the world of OpenNMS development.

Project Updates

• Stable: Current Release is 1.6.2

  1.6.2 is still the current release, and while there are a few fixes pending since it’s release, there are no immediate plans for a 1.6.3 yet.

• Unstable: Current Release is 1.7.0

  Trunk has been moving fast still, and I hope we’ll get a 1.7.1 release out soon-ish, but we’re still trying to get provisiond up to a demoable state first. In the meantime, feel free to try the nightly snapshots (if it’s not on a production system, of course).

• Trunk: Javamail Updates

  Dave’s been working on refactoring our javamail support into it’s own module, to make it easier to reuse in different portions of OpenNMS.

• Trunk: RANCID Integration

  Guglielmo continued work on the RANCID integration; the API has stopped changing much and most of the work has been going on in the UI at this point.

• Trunk: Provisiond

  Matt has most of the provisiond code working, some simple scanning is possible now, there are just a few loose ends to tie up before there’s a working prototype.

• Trunk: Node Page Updates

  Donald’s spiffy new ajaxy node page is active, and lets you page through data related to the node directly in the node page.

• 1.6 Testing: Minor Updates

  Jeff, Bill, and a few others have done some minor updates to 1.6-testing (which of course are forward-ported to trunk as well) including IE rendering issues, additional MIBs, read-only KSC report support, and more.

• Trunk: Map Updates

  Antonio has continued work on the new trunk map code, which includes support for all modern SVG browsers (Safari, Firefox, and IE with the Adobe SVG plugin).

• Trunk: RESTful Support for Map Data

  Matt Raykowski submitted RESTful API support for map and related data (map elements, linkd data, etc.) which will be useful for future map work.

• Trunk: XMP/Cartographer Support

  Jeff merged Bobby Krupczak’s Cartographer agent support for OpenNMS to trunk.

  Cartographer “implements a novel approach to managing distributed systems by automatically discovering and tracking the relationships between its component systems and applications. Cartographer does so via specially designed agents — residing on clients, servers and (potentially) network devices — that detect, identify, and track the inter and intra-system dependencies or relationships. Dependencies include network level services like DNS, DHCP, and SMTP as well as higher-level application abstractions like filesystems, databases, directory services, telephony, and middleware.”

Upcoming Events

• March 14th, 2009: OpenNMS User Conference Europe 2009 will be held in Frankfurt am Main, Germany.

• April 6th-10th, 2009: OpenNMS training will be available through The OpenNMS Group at the OpenNMS training facility in Pittsboro, NC.

If you have anything to add to the events list, or you wish to be a Dev-Jam sponsor, please let me know.

If You Can’t Love the Source You’ve Opened, Open the Source You Love

That’s all for this week. I hope you all have a wonderful valentine’s day if you’re into that kind of thing. As always, feel free to drop me a line if you have any questions, comments, or if you wish to know my address so you can send me some mysterious white powder through postal mail.

It’s time for another This Week in OpenNMS. I will be skipping next week’s, as I’ll be too busy sunning myself in the caribbean and hanging out with a bunch of rockin’ bands on Ships and Dip V. Ahhhhh….

Project Updates

• Stable: Current Release is 1.6.2

  1.6.2 seems to be holding up nicely, although there have been some reports of issues with JMX thresholding that need to be investigated more deeply still. If you’re having issues and can add some details to the bug on the subject, it would be appreciated.

• Unstable: Current Release is 1.7.0

  Trunk is still moving crazy fast, so hopefully we’ll be getting another 1.7 release out there soon when a few things settle down, so people can help test. In the meantime, feel free to try the nightly snapshots (if it’s not on a production system, of course).

• Trunk: Acknowledgement Daemon

  Dave continues to make progress on Ackd in between crazy days at the TeleManagement Forum’s Team Action Week (more on that later). Hopefully it will be ready for folks to test it out in the next few weeks.

• Trunk: Inventory Daemon

  Fresh off the heady high of getting WMI support in trunk, Matt Raykowski has started work on on inventory daemon, which intends to provide a more flexible interface to systems asset and inventory information than our current (anemic) asset system.

• Trunk: Provisiond

  Provisiond continues to progress towards something usable. Matt’s been working on finishing the scanning code, and Matt and I both have spent some time this week making an optimized SNMP table tracker which will let us perform operations on collected SNMP data as it comes in, so scans of nodes with large numbers of interfaces will happen in a more timely manner.

  I also finished up this week a RESTful API to the Provisiond importer, which will let you edit and create model-import and foreign sources. The web UI is next, and will use this API for creating provisiond’s configuration.

• Trunk: RANCID Support

  Guglielmo continues to flesh out the RANCID API. Work has begun on the OpenNMS web UI side of the implementation, and small changes are still being made to the RANCID java bindings.

• Trunk: Node Page Updates

  Donald continued his work on making the node page more dynamic.

TeleManagement Forum’s Team Action Week

OpenNMS, represented by OGP members Craig Gallen and David Hustace, is participating this week at the TeleManagment Forum‘s (TMF) Team Action Week (TAW) in Lisbon.

Craig is leading the TMF Interface Program (TIP) Reference Implementation (RI) team and we will be creating open source implementations of TIP interfaces starting with Service Problem Management (SPM).

The artifacts created by the reference implementation team will be libraries that can be used to develop NGOSS-compliant components in service provider applications. OpenNMS has committed to working on the Service Problem Management (SPM) interface (Alarms), Inventory, Performance Management, and Trouble Ticket implementations. For more information see the interface program page on TMF’s web site.

Upcoming Events

• February 2nd-6th, 2009: OpenNMS training will be available through The OpenNMS Group in Milan, Italy.

• February 9th-13th, 2009: OpenNMS training will be available through The OpenNMS Group at the OpenNMS training facility in Pittsboro, NC.

• March 14th, 2009: OpenNMS User Conference Europe 2009 will be held in Frankfurt am Main, Germany.

• June 14th-19th, 2009: OpenNMS Dev-Jam 2009, the annual OpenNMS developers conference, will be in Minneapolis-St. Paul this year.

Cruisin’

That’s it for now. We’ll see you again, in a couple of weeks! As always, if you have questions, comments, or angry hate-filled missives to send, let me know.

Sorry I missed last week, I ended up having so much come up I didn’t have time to put it together, so this issue is an action-packed 2-week OpenNMS extravaganza!

Project Updates

• Stable: Current Release is 1.6.2

  On January 15th, we saw the release of OpenNMS 1.6.2 which included a number of small bugfixes and feature additions.

  For the full list of what was changed, see the 1.6.2 bug milestone.

• Unstable: Current Release is 1.7.0

  The 15th also saw the first unstable release since 1.6 went stable. It is a work-in-progress release from trunk which gives a preview of the features to come in the 1.8 series. As 1.7.x releases come out, the release notes in the New and Noteworthy section of the web page will be updated with an overview of the new features which will be in 1.8.0.

• Trunk: Provisioning

  Provisiond is moving along, with lots more commits. Matt has been working on the scheduler and other infrastructure, and I’ve been working on the data model for the requisition (what nodes/etc. to import) and foreign source (what to do with the information imported). Things are moving along, and hopefully we will be doing actual scanning of node data soon.

• Trunk: RANCID Integration

  Guglielmo has been working more on the integration with RANCID for Cisco router management.

• Trunk: Acknowledgement Daemon

  Dave is continuing his work on the acknowledgement daemon. It’s approaching finished, and will hopefully be in a usable state in the nightly snapshots soon.

• Trunk: WMI Updates

  More work has been done on the WMI feature since 1.7.0 came out, including some architectural tweaking, and lots of new data collections.

• Trunk: Map Work

  More work has been going on in the OpenLaszlo map branch. From what I’ve been told, it’s approaching a usable/demoable state. Look for updates on this soon!

  Also, Antonio did some bugfixes and updates to the Firefox/Safari SVG maps, as well.

• Trunk: Node Page Enhancements

  Donald has been working on some new spiffy dynamic node pages which will allow you to browse node data, do simple queries, and other neat stuff, using Ext JS.

• Trunk: Asterisk Notification Support

  Jeff added support for notifications through Asterisk.

Upcoming Events

• February 2nd-6th, 2009: OpenNMS training will be available through The OpenNMS Group in Milan, Italy.

• February 9th-13th, 2009: OpenNMS training will be available through The OpenNMS Group at the OpenNMS training facility in Pittsboro, NC.

• March 14th, 2009: OpenNMS User Conference Europe 2009 will be held in Frankfurt am Main, Germany.

• June 14th-19th, 2009: OpenNMS Dev-Jam 2009, the annual OpenNMS developers conference, will be in Minneapolis-St. Paul this year.

If you have anything to add to the events list, or you wish to be a Dev-Jam sponsor, please let me know.

Adieu

That’s it for this week. As always, questions, comments, constructive and/or destructive criticism are always welcome. =)

It’s been a pretty busy week here in OpenNMS land.

Project Updates

• Stable: RT Ticketing Plugin

  Jonathan got his RT ticketing updates finished, along with some OTRS cleanup. These have been merged back into trunk and the 1.6-testing branch, so should be ready pending a review, for the 1.6.2 release.

• Stable: More Vendor Traps

  Jeff spent some time adding more SNMP collection, graphs, and trap events for a number of agents, including SNMP Informant and AIX.

• Trunk: IfIndex Persistence

  Antonio committed a small change to the event and alarm persistence code to allow Trapd to extract IfIndex from varbinds if it is available.

• Trunk: Provisioning

  We continued to focus on the new provisioning daemon and API, with a lot of design work and pair programming going on, especially on Matt’s part. We all spent time this week breaking the work up into smaller chunks so we can get a better idea of what our progress is.

  Donald continued to work on the detector code, adding more detectors, tests, and cleanups to the existing code.

  I’ve been working on creating the model for the configuration that will drive provisioning, including changing the default plugin behavior, defining custom behaviors for determining which IP and SNMP interfaces will be managed (as well as what categories the nodes will be put into). I’ve been learning much about JAXB along the way, which gives us an alternative to all of the intermediate wrapper code we tend to have to put around our existing Castor model objects.

  David’s been working on mocking up some code that will allow the provisioning system to automatically update a dynamic DNS server with information discovered during provisioning.

• Trunk: WMI Support

  Matt Raykowski continued to work on putting some finishing touches on the WMI support. There’s some more to do, but he’s hoping to get a first drop of it released into trunk any day now.

• Trunk: RANCID Integration

  Guglielmo committed the starts of what will become an implementation with RANCID, a tool for doing change management and configuration on Cisco devices.

  The first part wraps the existing (Tcl-based) RANCID tools with a web-services API. Next, we will be writing a plugin for the new provisioning API that can be called when managed node information changes.

• Other: Laszlo Maps

  Matt Raykowski also spent some time in a branch he and Joed have been working on to create network topology maps using OpenLaszlo. It’s not yet ready for integration into trunk, but a lot of good low-level work has been going on in that branch alongside the maps work.

• Other: Web UI Work

  Rob Moore committed some updates to Matt’s sandbox “expenses” application (a codebase to test out new technologies) which include a data grid and a sample query interface using JOSQL. We saw a preview of this at Dev-Jam this year, and it looks pretty sweet. Hopefully we can get it integrated into the OpenNMS web UI in the future.

Upcoming Events

‘Zat You, Santa Claus?

That’s it for this week.

The OpenNMS Group is off from Christmas to the new year, so things will probably be quiet next week. I want to wish you all a happy non-denominational, non-specific, non-offensive, winter solstice time celebration day!

As always, feel free to drop a comment my way if you have any suggestions, love- or hate-mail, or anything at all.

So far the response has been positive to TWiO, so it’s time again for another chapter.

Project Updates

• Stable: Ticketing Updates

  Jonathan Sartin worked more on the OpenNMS trouble-ticketing API, finishing up a change to allow ticketer plugins to be able to raise exceptions when errors occur. In addition, he resurrected work on an RT (Request Tracker) ticketer plugin. Both will be merged to the 1.6 branch when they’re ready.

• Stable: Bug Fixes

  I spent a little time this week cleaning up some bugs, mostly exceptions, simple bugfixes, and other minor changes.

• Stable: Windows Updates

  Bobby Krupczak was kind enough to lend a Win64 machine with Visual Studio so I could get 64-bit binaries built. They are available now on SourceForge. (Copy the jicmp and msvcr90 DLLs to your system directory, don’t forget to rename them to remove the -win64 bit.)

  In the process of working on that, a reasonably serious bug was found in the JICMP libraries on Windows. Windows passes around HANDLEs instead of file descriptors for the purposes of file I/O (and socket I/O). We were treating them as if they were normal file handles (ie, integers), which just happened to work on Win32, not because it was correct, but because we didn’t try to access the filehandle from Java directly. The code has now been cleaned up to treat socket operations on HANDLEs (well, SOCKETs) properly on Windows, and the new DLLs in the JICMP 1.0.9 binary release contain these changes (win32 and amd64).

  Additionally, it was determined that Windows XP, at least, is pickier about reading from raw sockets than other platforms, and requires that at least one packet is sent out the socket before reading any in (even though we’re just listening for any ICMP packets on the raw socket, so it shouldn’t really matter). This is fixed in the jicmp.jar in the 1.0.9 distribution; until 1.6.2 comes out, it is recommended you copy this jar over the one included in $OPENNMS_HOME/lib if you are running on Windows.

• Trunk: More Work on the New Provisioner

  Donald continued implementing “detectors”, the equivalent of Capsd’s protocol plugins, including a new asynchronous API which will allow us to interact with services at a much more granular level.

  Matt has proposed we use more agile development practices, and towards that goal, he started working on a document describing the current desired featureset of the provisioner. We’ve broken it up into chunks which will then be used to do code sprints so we can do a better job of divvying up the work. We’re working on going through and cleaning up the documentation and hopefully we’ll get it into the wiki soon.

• Trunk: Refactoring Maven (Services)

  Right now, one of the biggest chunks of code in our source tree is “opennms-services“. It’s kind of a dumping-ground of all of the high-level code that isn’t webapp code, and it’s a bit unweildy. I’ve started a branch to attempt to refactor at least some of it into smaller chunks (splitting out capsd, collectd, config, eventd, mock, notifd, poller, threshd, trapd, xmlrpcd, and so on). Work will be ongoing, but hopefully eventually we’ll have things a bit more manageable.

• (Almost) Trunk: WMI Support

  Matt Raykowski has been finishing up work on his WMI (Windows Management Instrumentation) monitor and collector and we hope to be merging it into trunk in the near future. There are just a few more finishing touches to put on it, and then it will be ready for inclusion in the future 1.8 release.

Upcoming Events

Development: A Brief Interlude

It’s time for a little aside on some of the tools we use for development.

Maven is an awesome tool, but with a large project like OpenNMS, checking repositories and other things are actually a significant drag on the build process. To help alleviate this (and to speed up building and sharing artifacts on our Bamboo continuous-integration server) we set up a Nexus proxy at the office. It worked so well, I set one up at home too. =)

If you’d like to set up your own, I’ve documented what we did on the OpenNMS wiki. Feel free to update it (and/or ask questions) if you run into any issues.

And on the subject of Bamboo, I realized I haven’t yet publicly thanked Atlassian for their generosity. They’ve generally been very generous to open-source projects, offering free licenses for their tools (continuous integration, bug tracking, etc.) OpenNMS has a very large build, and it can take a long time to work it’s way through the continuous-integration process even with a fast machine. They were kind enough to extend our open-source license to allow for more than the usual number of agents, and we’re now burning rubber with our entire set of classroom machines acting as build agents. No longer do we have huge queues of waiting builds, we get very timely Jabber notices when we break the build. Hm… maybe that’s not such a good thing after all.

Anyways, thanks again to Atlassian for the license upgrade, it’s working great!

That’s It for This Week

That’s it for now. I hope you’re enjoying these updates. If you have any questions or comments, or if you’ve done something cool with OpenNMS that you’d like included, please let me know.

I was recently remembering fondly the oldskool “OpenNMS Updates” that Shane O’Donnell used to do, and I thought I’d take a crack at reviving the tradition. So, without further ado…

Project Updates

• Stable: Current Release: 1.6.1

  OpenNMS 1.6.1 seems to be holding up without any huge bugs reported. There are no immediate plans for a 1.6.2 release but I would expect we’ll look into doing one in a month or so just to roll up any bugfixes that have happened, if nothing else.

• Stable: Configuration Tweaks

  David did some configuration changes that will be in a future 1.6 release which automatically roll up SNMP LinkUp and LinkDown traps into an alarm. Also, Jeff added a bunch of IETF and vendor MIB data collection and graphs to the 1.6 branch.

• Trunk: Provisiond

  Development is still churning along in trunk, with the focus on the Capsd rewrite. Since this is the first (of hopefully many) TWiO, I will go into a bit more depth.

  OpenNMS has always been written with scalability in the forefront of our minds, but JVM technology and development methodologies have moved a lot since we first started the project 9 years ago. Since the OpenNMS 1.2 series, and even a bit before, many of the subsystems of OpenNMS have been tweaked, cleaned up, and even rewritten for performance and other reasons. One of the things that’s needed attention for quite some time is Capsd, the part of OpenNMS that figures out what devices are on your network, and what those devices’ capabilities are (hence, Capsd).

  Matt Brozowski has been working on a complete replacement, called Provisiond. One of the benefits of the OpenNMS architecture is that it’s event-driven structure with distinct daemons for different subsystems makes it easy to make new implementations without breaking existing things. Thus, Provisiond will be installed (disabled, by default) alongside Capsd in 1.8, and in 1.10 (or 2.0), it will become the default capabilities scanner, with Capsd deprecated but not yet removed.

  The Provisiond architecture is such that a very robust threading model has been introduced to allow scanning huge numbers of resources in a very efficient manner, and the API has been written to make it very simple to implement new “detectors” which detect services and resources.

  Eventually this new architecture can (and should) be extended to polling/monitoring and data collection, but… one thing at a time.

  Anyways, Matt has been rockin’ the Java working on Provisiond, and I’ve been pairing with him off and on. I really like the way this code is shaping up. Donald in the meantime has been making tons of detectors so we can cover the large range of services we already detect with Capsd.

• Trunk: Mobile UI

  Alexander Finger started work on a simple mobile UI that gives you the outages summary on a single page (at least on my iPhone <g>).

  

Upcoming Events

From the Discussion Lists – Cartographer

[original thread]

Bobby Krupczak has created a tool called Cartographer which “implements a novel approach to managing distributed systems by automatically discovering and tracking the relationships between its component systems and applications.” In addition to the Cartographer protocol (XMP), software, and agent, he has written a collector plugin for OpenNMS which allows the collection and graphing of Cartographer XMP data. Very cool!

Hopefully soon we will get the collector integrated into OpenNMS proper and a future release (1.6 if it’s not too invasive, or at the latest, 1.8).

That’s It!

So that’s it for this week. Let me know if you think this is a useful thing for me to do, if there’s anything you’d like me to talk about that’s missing, or, well, if you have any comments at all. Until next week…
