Re: [Observium] Everything is DOWN after svn UP :-)
Hy *,
I also experienced this issue some minutes ago. My reason was that "someone" (svn?) created a .index file in the MIB Directory, which caused snmpwalk to die:
root@horstname:/opt/observium# /usr/bin/snmpget -v2c -c '***' -Pu -OQUst -m SNMPv2-MIB -M /opt/observium/mibs/rfc:/opt/observium/mibs/net-snmp 'udp':'horstname2':'161' sysObjectID.0 sysUpTime.0 add_mibdir: strings scanned in from /opt/observium/mibs/rfc/.index are too large. count = 136 MIB search path: /opt/observium/mibs/rfc:/opt/observium/mibs/net-snmp Cannot find module (SNMPv2-MIB): At line 0 in (none) sysObjectID.0: Unknown Object Identifier (Sub-id not found: (top) -> sysObjectID) sysUpTime.0: Unknown Object Identifier (Sub-id not found: (top) -> sysUpTime)
removing the /opt/observium/mibs/rfc/.index file fixed the glitch - does anybody know whats the purpose of these files and where do they come from?
Thanks Richard

Given that it's virtually impossible for this to be an actual bug in the SVN (hundreds of users would be complaining), it might help to have some additional information about your installation.
Do you know what version you updated from? What are you running it on? What version of net-snmp?

Hello,
Yesterday after upgrading observium (like everyday morning) we got hundreds of alerts. It seems that observium could not connect to any machine using SNMP - I checked this from console via ./poller.php and every server was unreachable, so I had to rollback to the earlier revision. Do you know anything about this?

I think this is perhaps, again, the pesky svn broken file issue.
This problem seems to have gotten significantly worse since the svn database version changes.

The .index file is created by net-snmp. It allows it to more quickly find MIBs without having to parse all of the files.
There's an ancient bug which causes the .index file to become corrupted. I've not heard much about it for a while, so I thought it was fixed in later versions.

Indeed, net-snmp creates this, then shits itself over it. We kind of never understood the how or the why.
Documented though: http://www.observium.org/docs/faq/ ("All my hosts seem down to Observium / SNMP doesn't seem to work anymore!")
