Has anyone setup SNMP to monitor AutoFS or a similar type of daemon on a Debain system? Thanks, Brian I ran across the solution to this and thought I would share it. By default Debian systems are not configured to have processes monitored by SNMP but it can be enabled by editing the /etc/snmp/snmpd.conf file. To do so look for the Process checks section about a third of the way down in the file and to monitor autofs you would enter something like this: proc automount You can do something more sophisticated if you wish but it is not necessary. There is plenty of documentation within the snmpd.conf file that you really don't have to go anywhere else for more information in most applications. Once again the Debian developers have made it so blatantly obvious that I completely missed it. I am sure the package maintainer is shaking their fist at the sky yelling, Just how simple do I have to make it! Debian is the best.

RE: Monitoring AutoFS in SNMP
If it spawns a new process each time it mounts a new partition, would it not have a parent process that would at least be constant on the server? If that's the case, maybe you should just monitor the parent process. Otherwise, it would make sense to monitor a partition instead of a pid for a specific spawned process. James It looks like the parent process snmp mib is also tied to it's pid and would change whenever the daemon is restarted. I am beginning to wonder if you can monitor Debian daemons at all with snmp. Brian -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe. Trouble?

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.

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-requ...@lists.debian.org with a subject of unsubscribe. Trouble?

I am sure it is a *good* thing security wise but it seems to be hampering usability at the moment. 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?

I assume that's why you'd want to monitor autofs in the first place anyways. James We are using autofs to mount cdrom and dvd iso images. There are nearly 100 of them. 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.
