Hi folks,
I have problems with host notifications in nagios 2.7. It may be, that I
had similiar problems with 2.5, which were the reason I updated nagios.
Here's my host configuration:
define host {
host_name eulep04
alias SAP Applikationsserver
address xxx.xxx.xxx.xxx
hostgroups Eule App. Server
contact_groups rz
notification_interval 45
notifications_enabled 1
notification_options d,r
check_command check-host-alive
max_check_attempts 3
active_checks_enabled 1
passive_checks_enabled 1
check_period 24x7
event_handler_enabled 1
check_freshness 0
freshness_threshold 0
obsess_over_host 0
flap_detection_enabled 1
process_perf_data 1
retain_status_information 1
}
I changed the host's IP Address to something that is not reachable, so
the service checks of the host failed an nagios issued host checks:
[1171127993] HOST ALERT: eulep04;DOWN;SOFT;1;CRITICAL - Plugin timed out
after 10 seconds
[1171128003] HOST ALERT: eulep04;DOWN;SOFT;2;CRITICAL - Plugin timed out
after 10 seconds
[1171128013] HOST ALERT: eulep04;DOWN;HARD;3;CRITICAL - Plugin timed out
after 10 seconds
Now, since the host is in an hard state, I would expect a notification
to go out. But there is no log of a notification attempt (I have enabled
the log_notifications option in nagios.cfg). Further, when looking at
the CGI I can see, that the host is down, but the "current attempt"
field is always "1/3".
In the following there are some failed service checks:
[1171128013] SERVICE ALERT: eulep04;CPU
Temperature;UNKNOWN;HARD;1;Sensor location cpu not found.
[1171128080] SERVICE ALERT: eulep04;SAP Logon;UNKNOWN;HARD;1;Cannot
connect to remote SAP system on host xxx.xxx.xxx.xxx.
...
but I do not see a host check attempt (could be ok: why check, if the
next service returns OK, the host is OK). The current attempt filed in
the CGI stays at "1/3"
Any ideas ?
Thanks in advance,
Thomas
