Excessive Service Check Times

[Jeff Engstrom]

Good morning,

 

            Does anyone know what might cause service checks to take
longer and longer to execute over a period of days?  It's very odd.
Some changes were made to the nagios.cfg a few months back due to the
lack of service parallelization.

 

/usr/local/nagios/bin/nagios -s /usr/local/nagios/etc/nagios.cfg
returns...

 

Nagios 1.0b6

        SERVICE SCHEDULING INFORMATION

        -------------------------------

        Total services:             759

        Total hosts:                121

 

        Command check interval:     -1 sec

        Check reaper interval:      1 sec

 

        Inter-check delay method:   USER-SUPPLIED VALUE

        Inter-check delay:          0.200 sec

 

        Interleave factor method:   SMART

        Average services per host:  6.273

        Service interleave factor:  7

 

        Initial service check scheduling info:

        --------------------------------------

        First scheduled check:      1099500060 -> Wed Nov  3 08:41:00
2004

        Last scheduled check:       1099500212 -> Wed Nov  3 08:43:32
2004

 

        Rough guidelines for max_concurrent_checks value:

        -------------------------------------------------

        Absolute minimum value:     5

        Recommend value:            15

 

...and the nagios.cfg...

 

check_external_commands=1

command_check_interval=-1

inter_check_delay_method=.2

service_interleave_factor=s

max_concurrent_checks=45

service_reaper_frequency=1

sleep_time=1

service_check_timeout=15

host_check_timeout=15

event_handler_timeout=15

notification_timeout=15

ocsp_timeout=5

perfdata_timeout=5

retain_state_information=1

process_performance_data=0

obsess_over_services=1

ocsp_command=submit_check_result

check_for_orphaned_services=1

check_service_freshness=0

freshness_check_interval=60

aggregate_status_updates=0

#status_update_interval=

enable_flap_detection=1

low_service_flap_threshold=5.0

high_service_flap_threshold=20.0

low_host_flap_threshold=5.0

high_host_flap_threshold=20.0

 

Any help would be a great help.  Thanks!
