We are using xymon-4.2.2 on rhel 5.2 server and more than 200
clients (HPC Cluster nodes).
Our requirement is :
-> If the node is powered down by scheduler for saving the power, it
is required that xymon should show its state as green and same for
other tests of same node.
Nodes powered down by scheduler are identified by pbsnodes command
which will show state as power.
-> If the node is going down by some other reason other that powering
down by scheduler, it should show red like normal clients.
Assuming your scheduler can have shell script hooks attached to events,
I'd add something to send a "disable" command before it brings a node
down, and then re-enable as it comes back up. If the nodes are being
powered down without state being saved (eg, not suspending/resuming
themselves), then just disable "until OK", otherwise I'd use some
arbitrary future value.
Relevant tests will be blue (not green, as requested), but that will be
handled as a non-event for SLA purposes.
Separately, it might be a good idea to have a separate server-side test
that sends node state about each node to xymon independent of the node
itself. That test is a fine place to put logic as well.
HTH,
