Hi - hope someone can clarify if this is a bug or not, I'm running Nagios
3.2.3 on SuSE, monitoring over 100 hosts and almost 1000 checks. I have a
varied number of time periods defined simply because some hosts / services
are offline or don't actually run 24x7 so are not neededto be alerted on.
However I have one specific group of servers that use a specific time
period and they continually log this:
[Mon Nov 7 21:30:00 2011] Warning: Check of service 'RDP 3389' on host
'TDUKSQLT3' could not be rescheduled properly. Scheduling check for next
week...
[Mon Nov 7 21:30:00 2011] Warning: Check of service 'RDP 3389' on host
'TDUKVIDC01' could not be rescheduled properly. Scheduling check for next
week...
[Mon Nov 7 21:30:00 2011] Warning: Check of service 'TCP 1352' on host
'TDUKAPPS22' could not be rescheduled properly. Scheduling check for next
week...
[Mon Nov 7 21:30:00 2011] Warning: Check of service 'TCP 1352' on host
'TDUKAPPS20' could not be rescheduled properly. Scheduling check for next
week...
[Mon Nov 7 23:46:00 2011] Warning: Check of service 'DEAL SERVER SERVICE
TCP 4099' on host 'TDUKUBS01' could not be rescheduled properly.
Scheduling check for next week...
etc.
These last entries all appeared last night after I'd manully "Re-scheduled
the next check of this service" via the GUI in the afternoon.
The time period these servers use is defined as:
define timeperiod{
timeperiod_name vmguesthours
alias VMWare Guest OS Hours
monday 21:30-06:30
tuesday 21:30-06:30
wednesday 21:30-06:30
thursday 21:30-06:30
friday 21:30-06:30
saturday 21:30-06:30
sunday 21:30-06:30
}
There's nothing unusual about the hosts defined and the templates used,
but below is an example of one anyway.
define host{
use unix_host_template ; Name of host
template to use
icon_image win40.jpg
host_name TDUKSQLT3
address 192.168.75.138
alias TDUKSQLT3 192.168.75.138
}
define service{
use remote-service
hostgroup_name vmwarehosts
service_description RDP 3389
contact_groups dtns-admins24x7,intel-support
check_period vmguesthours
check_command check_tcp!3389
}
define host{
notification_options d,u,r
max_check_attempts 3
check_interval 1
active_checks_enabled 1
notification_period 24x7
name unix_host_template ; Template
shared by hosts
notifications_enabled 1
check_command check_fping
contact_groups unix-admins-24x7
register 0
}
I've had a look around for this and its been reported before here -
http://tracker.nagios.org/view.php?id=31 - but it's not clear if this is
meant to be resoloved or not? For me it certainly isn't.
Any help would be greatly appreciated.
Thanks - Julian.
