Hi All
I'm new to this list so try to be kind :)
OS. Solaris with current patches applied
Hardware : Sun E220R, 2 * 450MHz Ultra SPARCII cpu's, 1gb ram, 2 * 18gb SCSi drives
Monitored Hosts: 64
Monitored Services 2094
Monitoring interval 5 mins
Nagios version 1.0 ( Yes I know there is a new version but an upgrade is not an option for us just now :( )
Problem:
nagios appears to be running fine it is just that when I look at my scheduling queue the tests at the top of the queue seem to be constantly 16 - 17 mins behind real time. Currently time on my box is 08:40. The next entry to run should have been executed at 08:24.
I have read the section in the docs regarding scheduling and adjusted my max_concurrent_checks accordingly. My service_reaper_frequency is still set to 10
Can any one point out where I can make changes to bring this system back into line with real time?
Here is the output from nagios -s ../etc/nagios.cfg
SERVICE SCHEDULING INFORMATION

Rough guidelines for max_concurrent_checks value:

Absolute minimum value: 62

>From nagios.cfg...
inter_check_delay_method=s
service_interleave_factor=s
max_concurrent_checks=186
service_reaper_frequency=10
sleep_time=1
service_check_timeout=63
host_check_timeout=30

ocsp_timeout=5
perfdata_timeout=5
Thanks for your help
