Feature request: Tactical overview metrics

[mjtrangoni]

Hi @stephen-soltesz,

I would like to have some metrics from the Nagios Tactical Overview, something like this, chapter 5.2 Combining with and/or.
It would be nice/better to implement it with labels, like nagios_services{state=hard,status=warning,acknowledged=true}=45.

• Hosts/Services:

1. The number of hosts/services with the hard state OK
2. The number of unacknowledged hosts/services in hard state WARNING
3. The number of acknowledged hosts/services in hard state WARNING
4. The number of unacknowledged hosts/services in hard state CRITICAL
5. The number of acknowledged hosts/services in hard state CRITICAL
6. The number of unacknowledged hosts/services in hard state UNKNOWN
7. The number of acknowledged hosts/services in hard state UNKNOWN

query_services:

GET services
Filter: scheduled_downtime_depth = 0
Filter: host_scheduled_downtime_depth = 0
Filter: in_notification_period = 1
Stats: last_hard_state = 0
Stats: last_hard_state = 1
Stats: acknowledged = 0
StatsAnd: 2
Stats: last_hard_state = 1
Stats: acknowledged = 1
StatsAnd: 2
Stats: last_hard_state = 2
Stats: acknowledged = 0
StatsAnd: 2
Stats: last_hard_state = 2
Stats: acknowledged = 1
StatsAnd: 2
Stats: last_hard_state = 3
Stats: acknowledged = 0
StatsAnd: 2
Stats: last_hard_state = 3
Stats: acknowledged = 1
StatsAnd: 2

query_hosts:

GET hosts
Filter: scheduled_downtime_depth = 0
Filter: host_scheduled_downtime_depth = 0
Filter: in_notification_period = 1
Stats: last_hard_state = 0
Stats: last_hard_state = 1
Stats: acknowledged = 0
StatsAnd: 2
Stats: last_hard_state = 1
Stats: acknowledged = 1
StatsAnd: 2
Stats: last_hard_state = 2
Stats: acknowledged = 0
StatsAnd: 2
Stats: last_hard_state = 2
Stats: acknowledged = 1
StatsAnd: 2
Stats: last_hard_state = 3
Stats: acknowledged = 0
StatsAnd: 2
Stats: last_hard_state = 3
Stats: acknowledged = 1
StatsAnd: 2

Thanks!

I really want this too.
One approach is of course to add some plugin on the monitoring box that gives a service/a check for these values that would be exported like any other check/metric...however, these stats are very Nagios/Check MK specific and I think it would make sense to simply export these core metrics as a special case (a "core feature" ;) ).

@mjtrangoni do I understand correctly that these summary metrics are accessible via the livestatus plugin?

If so, then I would welcome patches that query and export this data also. Is that something you're interested in helping with?
