  • Rnms now using TurboGears 2.3.2

    While the website might of been idle there has been a great deal of work behind the scenes (unless you’re looking at github) updating and improving RoseNMS, the python based Network Management System. The code has had a great many changes including:

    • Updating the TurboGears based code to 2.3.2
    • Simplifying the admin back to TG standard using the Twitter Bootstrap option
    • Making several GUI changes to make it easier to switch screens or get more information
    • Update to the pysnmp module to the latest, which is a much better module
    • Changing from paste to cliff for the command lines and bringing it all into one binary

    I’m hoping to get to release one in the next few months. The back-end is largely complete with some work required on the daemon and also more webGUI work to make sure its easy to get the right information at the right time.

     

  • jffnms 0.9.4

    JFFNMS version 0.9.4 was released today, this version fixes some bugs that have recently appeared in previous versions.

    Alarmed Interfaces and Events

    The triggers rules editor had a problem where some of the rules clicked off the triggers would not appear or could not be edited correctly.

    Most of the Admin screens have the ability to sort the rows. This, unfortunately, didn’t sort but the functionality has been restored.

    Most users are probably unaware of this, but the database schema is first created for MySQL and is then converted for PostgreSQL. The conversi0n process is far from ideal and hasn’t worked until this release. More testing is required for PostgreSQL support but it should be a lot better.

  • JFFNMS 0.9.3

    JFFNMS version 0.9.3 has been released today.  This is a vast improvement over the 0.9.x releases and anyone using that train is strongly recommended to upgrade.So what changed? What didn’t change!  A nice summary would be fixing a lot of things that were broken or needed some tweaking. A really, really big thanks to Marek for all the testing and bug reports and also patient “just run this and tell me what it says” tests he did too.  If something wasn’t right before and works now, it is quite likely it is working because Marek told me how it broke.

    A brief overview of what has changed:

    • TFTP transfers work again
    • A lot of the wierd polling effects due to caching fixed
    • Lots of the selects in sub-tables now work
    • The PHP string-to-float brokeness in SLAs worked-around
    • Even more SNMP library cruft removed or escaped
    • HostMIB apps match properly
    • Interface autodiscovery delete and update fields back working

    You can download the file off sourceforge at

  • JFFNMS 0.9.3 1st release candidate

    I have been putting a lot of testing into JFFNMS lately.  I have been very lucky to have had someone with the time and patience to try out various sub versions and give me access to their results.

    The end-result of all this testing is a much, much less buggy JFFNMS.  There have been a strack of problems with caching results, for example, where status would not be updated or even worse the status of one device impacted on another.

    The poller parent scheduler had a problem too where it would almost always sit in the first child starving the others of work which slowed things down. The scheduler now is a lot fairer across the children giving a speed up. I’ve heard speed-ups of 15x for this one change alone.

    I also had a curious bug where if a device was set to not gather state it still did and created events but not alerts.  This meant your event table was spammed with down interface alerts even on interface you know are down and you turned state checking off.  0.9.3 now does it the right way.

    The first RC is now uploaded and can be found at https://sourceforge.net/projects/jffnms/files/jffnms%20RC/ to try out.

    I’m a little worried that the pollers now run too fast and could overwhelm the usually crummy control stack found in network devices for parsing SNMP.  I’m interested to hear how people find it.

  • JFFNMS 0.9.2 Released

    JFFNMS Interfaces and Events

    JFFNMS version 0.9.2 was released today both as an upstream tar.gz file and a new Debian package.  This version fixes some bugs including making sure it works with PHP5.4.

    The biggest change in PHP 5.4 is that you can no longer call by reference.  Previously you could call a function like myfunc(&blah); which would send a pointer to blah and not the item itself. Now the function definition needs to define what it wants rather than change it each time.

  • JFFNMS – 3rd RC lucky?

    I’ve just uploaded to sourceforge the third and hopefully last RC for JFFNMS network management system version 0.9.0  The reason for the delay was easter as well as I wanted to test the engines for a long while to make sure I was not getting any orphan children or items. Previous versions had processes that never died or if they died the parent didn’t realise and didn’t handle the item, permanently making the item “out for work”.

    PHP5 has much better job and process handling and the new version takes advantage of this handling.  It’s run well on my on test setup for a week or two. You can find the RC code or just the older releases at https://sourceforge.net/projects/jffnms/files/
