Hi Icinga-users.
I am currently configuring Icinga to monitor my cluster.
My problem is now that the nodes mount a bunch of NFS shares, which i of
cause will like to check is properly mounted.
So what I have done is make a custom service as follows:
apply Service "nfs" {
import "generic-service"
check_command = "disk"
vars.disk_partitions = [ "/pack" , "/scripts" , "/user" ,
"/projects" , "/tools" ]
vars.disk_wfree = "20%"
vars.disk_cfree = "10%"
vars.disk_units = "GB"
command_endpoint = host.vars.remote_client
assign where host.vars.remote_client
}
This produce the following ouput in icinga-web
DISK OK - free space: /pack 980 GB (97% inode=98%): /scripts 466 GB (99%
inode=99%): /user 4567 GB (94% inode=99%): /projects 3335 GB (70%
inode=99%): /tools 0 GB (99% inode=99%):
My will like to check that the nfs shares are accesible and mounted,
therefore i tried to unmount on of the shares, which did not produce a
warning in icinga2, the share simply disappeared from the output, e.g.
birdnes:~$sudo umount /tools
produce this plugin output
DISK OK - free space: /pack 980 GB (97% inode=98%): /scripts 466 GB (99%
inode=99%): /user 4567 GB (94% inode=99%): /projects 3335 GB (70%
inode=99%): / 213 GB (95% inode=97%):
if I unmount all the nfs shares, the check simply defaults to check the
root partition /, and it therefore still appears to be okay.
What is the propper way to test if NFS shares is mounted and accessible?
I tried the above with a physical disk, which caused the service to
change to unknown status.
