Nagios Support Forum

The way we do it is to monitor both hosts individually and the cluster itself as a third host. It is not necessary to set NSClient++ as a clustered service this way. The standard set of service checks are applied to the individual hosts, plus the SQL Server checks. The cluster virtual host gets chec...

Thank you! I will check that out.

Does anyone have suggestions for monitoring hosts with large amounts of memory? I mean hundreds of GB here. We use NSClient++, but mostly the check_nt style checks unless we need something beyond that. The check_nt MEMUSE check works, but takes its warning and critical thresholds as integer percents...

Exchange has a number of queues, so you'll have to determine which ones you want to monitor for yourself. You can monitor Exchange queues using Windows performance counters. We are using Exchange 2010, so the names may have changed, but these are the queues we monitor: Aggregate Delivery Queue Activ...

I have a MIB for the OID's I want to use, how do I get Nagios to interpret that file. I used snmpwalk to test the OID's and I get valid data back while in terminal, now I need to setup my service in Nagios to read this OID and send out alerts if a threshold is passed. If you have a .mib file, insta...

I think you're on the right track. You have to pass the Nagios macros as parameters to the script. So, I think you'll end up with something along the lines of: define command{ command_name notify-service-by-email-test command_line /usr/local/nagios/libexec/recovery.sh $NOTIFICATIONTYPE$ $SERVICEDESC...

I haven't completely understand this one. should i have only one templates without/with ""r"" ? and then add above command to command.cfg file. The contact needs to have the w, c, and r. The idea is that Nagios is satisfied the contact will receive everything. Then the notificat...

I had another idea which (if it works) is certainly easier and better than changing the source code. It might be possible to use a custom notification command instead. Something along these lines: define command { command_name recovery_only command_line if [ "$NOTIFICATIONTYPE$" -eq "...

I should word my post better! This is the line I meant you should remove, if you try that route: if(!((svc->notified_on_unknown == TRUE && cntct->notify_on_service_unknown == TRUE) || (svc->notified_on_warning == TRUE && cntct->notify_on_service_warning == TRUE) || (svc->notified_on_...

I think Nagios isn't set up to be able to do what you want to do. I don't speak the language, but I looked at the source in notifications.c anyway. This bit looked interesting. if(svc->current_state == STATE_OK) { if(cntct->notify_on_service_recovery == FALSE) { log_debug_info(DEBUGL_NOTIFICATIONS, ...
