Hi, I have installed the latest version of NAV (4.8.6) and have added some of our Extreme switches. SNMPv2-MIB :: sysDescr.0 = STRING: ExtremeXOS (X440-48p-10G) version 16.2.2.4 16.2.2.4-patch1-3 by release-manager on Fri Feb 17 08:00:10 EST 2017 However, I get the following error message in the log file ipdevpoll.log --- 2019-01-24 11: 33: 09,664 [WARNING nav.mibs.entity_mib.entitymib] [statuscheck ex035.inet.hb.se] device response has bad table index .19.48 in ENTITY-MIB :: entPhysicalTable, ignoring --- What does this mean? Is there a solution? Are extreme switches supported by NAV? Sincerely Per-Olof Axelsson University of Borås

We observe a WS-C93XX (Catalyst 93xx Switch Stack from cisco) where for some MAC-addresses information about switch port is missing. All jobs have run recently, no error message about the topo job in ipdevpoll.log. Any ideas? --Ingeborg -- Ingeborg Østrem Hellemo -- ingeborg.hellemo(a)uit.no Dep. of Information Technology --- Univ. of Tromsø

Get time out when accessing nav/ipdevinfo/{device}
by Jo Øiongen 05 Nov '18

05 Nov '18

Hi! Upgraded to latest and greatest a couple of days ago. After that everything works, except accessing devices. I have http://nav/ as my NAV URL root. Trying to access http://nav/ipdevinfo/{device} gives: Gateway Timeout The gateway did not receive a timely response from the upstream server or application. Can someone please point me in the right direction for where to start to look? I did a double upgrade. Debian and NAV. To get Debian up and running, including going from PostgreSQL 9.4 to PostgreSQL 9.6 I had to make some room on the hard drive. So I did a "cd /var/lib/graphite/whisper/nav/devices/" + "rm -rf *" Did I mess up here? BR, Jo

Separating back-end processes
by William Daly - Network Specialist, VUSD Technology 13 Sep '18

13 Sep '18

Hello all, The metrics that were currently collect only keep increasing overtime. We would like to separate the various parts of NAV on to different servers to spread the resource burden. I have explored the idea of moving postgres and carbon to a different server. What would you recommend? Can I get away with just clustering Carbon? Thanks, William Daly Network Specialist Vacaville Unified School District (707) 453-6170
