Announcement: NAV 3.11.4 released
NAV 3.11.4 is now available for download at Launchpad: https://launchpad.net/nav/3.11/3.11.4 This maintenance release contains fixes for 7 reported issues, as well as some performance improvements to the collection system: Bugfixes: * LP#644155 (Network Explorer never returns response to some searches) * LP#912276 (Device History Request-URI Too Large) * LP#996955 (All sensor stats are named "Sensor", and clutter the ipdevinfo view) * LP#997008 (Failed ipdevpoll jobs aren't properly rescheduled) * LP#997606 (add option to run each ipdevpoll job type in separate process) * LP#997980 (bad MAC for IPv6 addresses from Catalyst 6500) * LP#999606 (dhcping is not documented as requirement for DHCP service monitor) Various performance-related improvements: * Internal caching of collected SNMP variables pr. ipdevpoll SNMP session. * Various tweaks to avoid producing unnecessary SNMP queries. * Added database indexes for some potentially slow and frequently used queries. * Added ipdevpolld multiprocess option to run each job type as separate subprocess (enabling this will consume up to 60 PostgreSQL connections, be warned!) * An -n option was added to ipdevpolld. Used in combination with the -J option, ipdevpoll will run a single job for a single netbox as a foreground process. * When new jobs are added to the internal ipdevpoll job queues, boxes are prioritized in ascending order of last update time. I.e. ipdevpoll will run jobs first for boxes that are new or haven't completed an inventory job in a long time. Please report bugs at https://launchpad.net/nav/+filebug :-) Binary packages for Debian will be made available as soon as possible. The Debian package is maintained by Morten Werner Forsbring, on commission From UNINETT. Happy NAVing everyone! -- Morten Brekkevold UNINETT

The Debian package is available as Alioth [1] as usual. - Werner [1] http://pkg-nav.alioth.debian.org/

Where is the documentation about how you enable/use this? --Ingeborg -- Ingeborg Østrem Hellemo -- ingeborg.hellemo@uit.no Dep. of Information Technology --- Univ. of Tromsø

I guess here: ./ipdevpolld --help Usage: ipdevpolld [options] Options: --version show program's version number and exit -h, --help show this help message and exit -f, --foreground run in foreground instead of daemonizing -s, --log-stderr log to stderr instead of log file -j, --list-jobs print a list of configured jobs and exit -p, --list-plugins load and print a list of configured plugins -J JOBNAME run only JOBNAME in this process -n NETBOX, --netbox=NETBOX Run JOBNAME once for NETBOX. Also implies -f and -s options. -m, --multiprocess Run ipdevpoll in a multiprocess setup -P, --pidlog Include process ID in every log line This program runs SNMP polling jobs for IP devices monitored by NAV -- John-Magne Bredal UNINETT AS

Hm, I don't know what OS or version you're running, but python-twisted must be installed and it should have the runner module built in. python-twisted should be available in Ubuntu and Debian. -- John-Magne Bredal UNINETT AS

OS is FreeBSD py27-twistedRunner-12.1.0 (and the rest of the twister-packages for good measure) is now installed.

Any ideas?
Might either be some version differences in Twisted, or something that just works plain differently under FreeBSD (as usual) ;) Would you please try the attached patch, which explicitly attaches the parent environment to each subprocess? -- Morten Brekkevold UNINETT
