Monitoring AutoFS in SNMP
in [Debian]
|
From: Brian on 23 Mar 2010 10:10 I am trying to find a MIB to monitor AutoFS but everything I find is tied to the current pid AutoFS is running under which of course changes each time it is restarted making it useless as a monitoring metric. Has anyone setup SNMP to monitor AutoFS or a similar type of daemon on a Debain system?

Isn't that a *good* thing? I'd look at the "restart" section of the autofs startup script to see if there's a way to "regenerate" the MIB when you restart autofs. Maybe, though, that's too hackish. -- "History does not long entrust the care of freedom to the weak or the timid."

I'm not familiar with autofs but if you do a snmpwalk for OID ..1.3.6.1.2.1.25.2.3.1, you will find a listing of all the mounted partitions, maybe instead of monitoring autofs, monitor the existence of a specific partition instead? I assume that's why you'd want to monitor autofs in the first place anyways. James -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe". Trouble?

I don't think you can rewrite a MIB on the fly. I am no expert but I think they are written as products are developed then distributed as a support service. I am curious though, it there a way to force a daemon to take a specific pid at startup?

Too many to really monitor individually so we wanted to just monitor autofs. It looks to me like each auto.* file in /etc spawns it's own process and pid. And the pid changes each time the daemon is restarted or the mount point expires and is then re-mounted. If we could just monitor the pid spawned by auto.master I think that would do it for us. I asked in another reply in this thread if a daemon could be assigned a pid but don't have a response yet.
