Link surveillance with NAV
by Sigurd Mytting 17 Des '10

17 Des '10

Hi! Wondering how other NAV'ers are doing link surveillance? I'm mostly interested in downed routing-ports, but also normal switch-ports, both host-access and switch-trunks, could of interest. Any input is appreciated! Cheers, -Sigurd

Cricket trouble/optimizing
by Sigurd Mytting 17 Des '10

17 Des '10

Hi! Running NAV 3.7.0 on Debian 5-64-bit, about 700 switches and routers currently in NAV. There has been a lot of weird stuff (trouble) happening with Cricket after going from the latest in the 3.5-series up to 3.7, some things got better from 3.6 to 3.7, but not all is perfect. Not complaining, just a summary from my point of view over the last months of releases. About a week ago my Cricket graphs just stopped and after some debugging I found the Cricket-cronjob run as navcron dies after a while and leaves a lock-file, cleaning it up and doing some optimizing (separating switch and router interfaces, and system values into separate cronjobs) I found the cronjobs still dies and leaves lock-files. First of all; anyone else seeing the Cricket collector dying? (In my case just about on every run.) Second; Anyone have a good tip on how to tune Cricket to run a sensible number of jobs to get thru it all in a sensible amount of time? Currently, if the largest job (switch interfaces) don't die after only a few minutes it usually runs for 25-30 minutes. NAV in my environment isn't really a production system, but my pet-project provides more accurate and sensible information than any system we have in production so I'll hang on to it as long as I can. Any input appreciated! Cheers, -Sigurd

Trouble with NAV 3.70 ,NFSEN on Debian 5
by Tore Willmar Jakobsen 17 Des '10

17 Des '10

Hi, I have installed Debian 5-64 bit on a virtual machine. On top of that NAV 3.7.0 is installed , also NFSEN 1.3-5 and NFDUMP 1.6.1p1 Everything work as expected , but not graphs is generated through Cricket 1.0.5-9 The logs show errors from NfSenRRD.pm : Unable to create graph, no such file or directory. The graph windows in Nav is displayed , but no data is available visually. After googling a lot of users see the same problems as I have experienced. They all have downgraded lots of libraries in Perl and Cricket. Anyone done this setup with success on Debian 5. Solution is highly appreciated [cid:image001.jpg@01CB96B8.C14ED8F0] Tore Willmar Jakobsen Chief Consultant / Sjefskonsulent - Datarom Wintel Mobile: +47 99 27 98 81 tore.willmar.jakobsen(a)atea.no<mailto:marit.garvik@atea.no> Atea AS, Jåttåvågveien 7 4020 Stavanger Switchboard: +47 22 09 50 00 www.atea.no<http://www.atea.no/> P Before printing, think about the environment
