Hello everyone !
I’m facing problems with latency. We’ve got Nagios 3.2.0 and we’re monitoring almost 800 hosts, with one service for each.
I’m taking over the adminsitration of the Nagios server so I’m not fully aware of the choices of configuration that have been made, but I guess that so far, hosts and services are both pinged, which is useless for us, because we care only about the services.
To be sure of that, I ran nagios3stats with this result :
[code]Total Hosts: 758
Hosts Checked: 758
Hosts Scheduled: 758
Hosts Actively Checked: 758
Host Passively Checked: 0
Total Services: 843
Services Checked: 843
Services Scheduled: 843
Services Actively Checked: 843
Services Passively Checked: 0[/code]
So is it ok to say that hosts and services are both checked ?
I want to know how often the check hosts are done. The nagios3 -s command gives me :
[code]HOST SCHEDULING INFORMATION
Total hosts: 758
Total scheduled hosts: 758
Host inter-check delay method: SMART
Average host check interval: 300.00 sec
Host inter-check delay: 0.40 sec
Max host check spread: 30 min[/code]
So it seems here that hosts are checked every 5 min, right ?
The hosts definitions are using the generic-host template, but it seems there’s no check_interval defined :
name generic-host ; The name of this host template
notifications_enabled 0 ; Host notifications are enabled
event_handler_enabled 1 ; Host event handler is enabled
flap_detection_enabled 1 ; Flap detection is enabled
failure_prediction_enabled 1 ; Failure prediction is enabled
process_perf_data 1 ; Process performance data
retain_status_information 1 ; Retain status information across program restarts
retain_nonstatus_information 1 ; Retain non-status information across program restarts
SR max_check_attempts 3
max_check_attempts 3 notification_interval 0 notification_period 24x7 notification_options d,u,r contact_groups admins register 0 ; DONT REGISTER THIS DEFINITION - ITS NOT A REAL HOST, JUST A TEMPLATE![/code]
So where does Nagios take its value for the check_interval for the hosts ?
Thank you for any answer you would give me !
