Monitoring filesystems?
list Vernon Everett
Hi Henrik
Our disaster here has got me thinking about monitoring file systems.
At present, Hobbit monitors the usage of a file system, but is there a
way to check if it's there or not.
Hobbit is quite happy if your NFS or Veritas volume doesn't mount, as
long as the capacity of what is mounted is within tollerance.
How can we make it check if the disks are actually mounted?
Or is that a task for an external test?
Regards
Vernon

It would be fairly easy to add a check in the client disk handler so that you could configure certain filesystems that must be present in the disk status report. Right now the client config goes like disk /export/home 80 95 which as you say just defines the thresholds. We could add a "required" keyword after the thresholds and if it's there, then the disk status will go red if it's not there - same as we do for the process checks. Regards, Henrik

On a similar line of thought. I've been trying to set up our fileserver (NFS and SAMBA on Fedora core 2 Linux) to show nfs exports using network2.sh and/or bb-nfs. Neither one is showing on the hobbit monitor, nor are files being generated in the hobbit server's data/hist or data/histlogs directories. Oddly, I have the network2.sh working on numerous other servers and it works fine. Those are also RedHat variants, mostly CentOs. The setups in bb-bbexttab and bbsys.local are identical to the ones that work, network2.sh exists with proper permissions and I've restarted the client and server scripts numerous times. The startup of bbclient on the fileserver shows that network2.sh is one of the external scripts that is started. Am I missing something obvious here ?

I have used both the bb-meta and bb-vxcheck scripts with good success over the years. They are available on deadcat.net and should be compatible with a Hobbit client, but I'm not sure about the server. Cheers, -Shaun

Don't you love it when someone answers his own post for help ? The issue was that both bb-nfs and network2 rely on ksh, which wasn't installed on the fileserver. linking to bash worked. So it was indeed something obvious. Thanks to all, especially Henrik, for a great tool.
