service dependencies

Wed Apr 18, 2007 1:38 am

Is there a way to set service dependencies so that if a machine is truly down (no ping) that the other services will not notify until the machine is back up? As it is now if a machine has several services I get a notification for each service when the machine is down.. I do want those notifications if individual services go down but if the entire machine is down 1 notice that the PING service has failed would be sufficient..

I am using version 2.0 of The Dude..

Thanks so much for making this product it has been fantastic discovering all of the features..

In every device you can set its 'parents'. If a 'parent' is down, The Dude will not report any changes in it's 'children'.

that is for machine dependencies.. I am looking for service dependencies.. imagine the following scenario:

Server A has HTTP, CPU, DISK, and PING services.. I want to know if any of those 4 go down individually certainly.. but if the machine can't ping then obviously the other 4 services are likely to be down as well because the machine is off of the network.. in this case I really only need one notification that the machine is down PING and not 4 notifications that each other service is down..

I guess I am used to the way Nagios handled this where you had a check_host_alive routine that was separate from the services and if it went down it wouldn't even check the services on that machine until that check_host_alive routine (usually a ping) came back up..

If it's not possible maybe just add it to the list as something to look at in future versions..
