Same LTM Monitor applied to different Pools with Common Nodes

We have a several nodes that are used multiple pools and each of the Pools has the same monitor associated with them.  My question is will each node be monitored separately for each pool even though the monitor is the same?  We are going through some clean up and trying to validate that the monitoring in place is not causing more traffic than needed.  We have also started to alert on when a node fails monitor and have started to notice that they are failing not due to a bad response but due to no response.

Thanks in advance,

Joe
