[Nagios-users] Nagios Optimization on CentOS
Hello. I've installed Nagios Core 3.3.1, and can't get it to run very fast at all. Machine specs: OS: CentOS 5.7 Processor: Intel(R) Xeon(R) CPU E5420 @ 2.50GHz (8 cores) RAM: 8G HD: 800G, 22G used Going by top, the load average of the machine hovers around 1.5-2.0. CPU usage is around 12% across all cores. Memory usage shows about 7.5G being used for buffers, so memory is actually pretty unused too. The reason this seems incredibly underused to me is because we have 6000 hosts we're pinging. Total time for this check is around 6-7 minutes. Considering the lack of load on this box, I'm pretty sure we can improve the total time significantly. We are going to aim for distributed monitoring, we're just not there yet. I figure that's going to take another week or two for me to be comfortable implementing. I'm also attaching the main nagios.cfg file. If there's more information that's needed, please let me know. =nagios.cfg= accept_passive_service_checks=1 admin_email=nagios admin_pager=pagenagios broker_module=/usr/local/nagios/bin/ndomod.o config_file=/usr/local/nagios/etc/ndomod.cfg cfg_file=/usr/local/nagios/etc/checkcommands.cfg cfg_file=/usr/local/nagios/etc/contactgroups.cfg cfg_file=/usr/local/nagios/etc/contacts.cfg cfg_file=/usr/local/nagios/etc/hostgroups_auto.cfg cfg_file=/usr/local/nagios/etc/hostgroups.cfg cfg_file=/usr/local/nagios/etc/hostgroups_network_auto.cfg cfg_file=/usr/local/nagios/etc/hosts_auto.cfg cfg_file=/usr/local/nagios/etc/hosts.cfg cfg_file=/usr/local/nagios/etc/hosts_nrpe.cfg cfg_file=/usr/local/nagios/etc/hosts_routers_auto.cfg cfg_file=/usr/local/nagios/etc/hosts_switches_auto.cfg cfg_file=/usr/local/nagios/etc/misccommands.cfg cfg_file=/usr/local/nagios/etc/nrpe_auto.cfg cfg_file=/usr/local/nagios/etc/services_auto.cfg cfg_file=/usr/local/nagios/etc/services.cfg cfg_file=/usr/local/nagios/etc/services_cisco.cfg cfg_file=/usr/local/nagios/etc/services_manual.cfg cfg_file=/usr/local/nagios/etc/services_nrpe.cfg cfg_file=/usr/local/nagios/etc/services_routers_auto.cfg cfg_file=/usr/local/nagios/etc/services_switches_auto.cfg cfg_file=/usr/local/nagios/etc/timeperiods.cfg check_external_commands=1 check_for_orphaned_hosts=1 check_for_orphaned_services=1 check_result_reaper_frequency=2 check_service_freshness=1 command_check_interval=-1 command_file=/usr/local/nagios/var/rw/nagios.cmd date_format=us enable_embedded_perl=1 enable_event_handlers=1 enable_flap_detection=0 enable_notifications=1 enable_predictive_host_dependency_checks=1 enable_predictive_service_dependency_checks=1 event_handler_timeout=30 execute_host_checks=1 execute_service_checks=1 external_command_buffer_slots=4096 freshness_check_interval=60 high_host_flap_threshold=20.0 high_service_flap_threshold=20.0 host_check_timeout=30 host_inter_check_delay_method=n host_perfdata_command=process-host-perfdata host_perfdata_file_mode=a host_perfdata_file_processing_command=process-host-perfdata-file host_perfdata_file_processing_interval=15 host_perfdata_file_template=DATATYPE::HOSTPERFDATA\tTIMET::$TIMET$\tHOSTNAME::$HOSTNAME$\tHOSTPERFDATA::$HOSTPERFDATA$\tHOSTCHECKCOMMAND::$HOSTCHECKCOMMAND$\tHOSTSTATE::$HOSTSTATE$\ tHOSTSTATETYPE::$HOSTSTATETYPE$ host_perfdata_file=/usr/local/pnp4nagios/var/host-perfdata illegal_macro_output_chars=`~$|' illegal_object_name_chars=`~!$%^*|'?,()= interval_length=60 lock_file=/usr/local/nagios/var/nagios.lock log_archive_path=/usr/local/nagios/var/archives log_event_handlers=1 log_external_commands=1 log_file=/usr/local/nagios/var/nagios.log log_host_retries=1 log_initial_states=1 log_notifications=1 log_rotation_method=d log_service_retries=1 low_host_flap_threshold=5.0 low_service_flap_threshold=5.0 max_check_result_reaper_time=10 max_concurrent_checks=0 max_host_check_spread=2 max_service_check_spread=2 nagios_group=nagios nagios_user=nagios notification_timeout=30 obsess_over_services=0 ocsp_timeout=5 perfdata_timeout=5 process_performance_data=1 retain_state_information=1 retention_update_interval=60 service_check_timeout=60 service_inter_check_delay_method=n service_interleave_factor=10 service_perfdata_command=process-service-perfdata service_perfdata_file_mode=a service_perfdata_file_processing_command=process-service-perfdata-file service_perfdata_file_processing_interval=15 service_perfdata_file_template=DATATYPE::SERVICEPERFDATA\tTIMET::$TIMET$\tHOSTNAME::$HOSTNAME$\tSERVICEDESC::$SERVICEDESC$\tSERVICEPERFDATA::$SERVICEPERFDATA$\tSERVICECHECKCOMMAND:: $SERVICECHECKCOMMAND$\tHOSTSTATE::$HOSTSTATE$\tHOSTSTATETYPE::$HOSTSTATETYPE$\tSERVICESTATE::$SERVICESTATE$\tSERVICESTATETYPE::$SERVICESTATETYPE$ service_perfdata_file=/usr/local/pnp4nagios/var/service-perfdata sleep_time=1 state_retention_file=/usr/local/nagios/var/status.sav status_file=/usr/local/nagios/var/status.log status_update_interval=15 temp_file=/usr/local/nagios/var/nagios.tmp use_agressive_host_checking=0 use_large_installation_tweaks=1 use_retained_program_state=0 use_syslog=0
[Nagios-users] Nagios on CentOS
Hi I have earlier used Nagios on Fedora 13 and was successful in installing Nagios without any hiccups using the quick installation guide meant for Fedora. I wanted to know if i can follow the same steps for installing Nagios on CentOS assuming that i have a default CentOS installation. Also let me from which version of CentOS would it be good to install the latest Nagios. Appreciate your responses and suggestions in this regard. Thanks Jatin -- Write once. Port to many.

If there is no compelling reason - use the latest - centos 6. I have run nagios on centos for many years, it works well ... the main problem is that the default config has changed several times, directories changed, etc, which has broken it several times ... not to hard to get working again, but a pain. -- Alain Williams Linux/GNU Consultant - Mail systems, Web sites, Networking, Programmer, IT Lecturer. +44 (0) 787 668 0256 http://www.phcomp.co.uk/ Parliament Hill Computers Ltd.

Re: [Nagios-users] servicedependencies not working
Yeah I've been starting to play with using hostgroups to tie them together
since I can't really use hosts, but so far just limited on time due to
holidays, I hope to get more testing done this week but initial testing looks
like if I can specify the hostgroups in these configs then it works.

I've started playing with making a bunch of dependencies and at first it
appeared to be working, right now I've got a pretty basic test setup. I've
added one service to be dependent on the other one, but it seems that the
freshness might be mucking with it. Two services below:
define service {
service_description base_log_checks
servicegroupsbase_service_group
hostgroup_name base_windows_2003
use generic-passive-service
check_freshness 1
freshness_threshold 3600
check_commandservice_is_

define service {
service_description nagios_cron
servicegroupsbase_service_group
hostgroup_name base_windows_2003

check_commandservice_is_stale
}
define servicedependency {
service_description nagios_cron
dependent_service_description base_log_checks
execution_failure_criteria w,u,c
notification_failure_criteria w,u,c
inherits_parent 1
}
What appears to happen is that I kill nsclient so nagios_cron starts
reporting stale at 3000 seconds, and the same for base_log_checks shortly
after. Then about every hour I get more stale soft alerts, and then after
the third try it goes to a HARD alert and I still get a ticket, though I'm
not sure why it's even checking if execution should be disable when
nagios_cron is in a warning state. But not only does the active checks
(service_is_stale) get executed but I'm also still getting notifications sent
after 3 attempts, so it doesn't really appear to be doing anything.
Unfortunately right now these servers are so busy it's hard to put them in
debug mode. Have I missed something obvious with these?
I must say though, with the size of your environment, it's quite possible that
just looking up the dependency takes longer than it does to just execute the
extra check. If you're looking to save time, that might well bite you in the
ass. It's something that will probably be improved til Nagios 4, but it will
require a change in Nagios' object structure, so we can't really do it without
upping the major version number :-/

Re: [Nagios-users] Nagios Optimization on CentOS
Are you using fping instead of regular ping? It is a different package from ping that needs to be installed separately. Here is an excerpt from its man page: fping is a like program which uses the Internet Control Message Proto- col (ICMP) echo request to determine if a target host is responding. fping differs from ping in that you can specify any number of targets on the command line, or specify a file containing the lists of targets to ping. Instead of sending to one target until it times out or replies, fping will send out a ping packet and move on to the next tar- get in a round-robin fashion. Good Luck, Gregg.

Re: [Nagios-users] servicedependencies not working
Adding in the hostgroups seems to get things working as I would expect. I
guess this is another case where active checks does not include those
performed by freshness checking. Even though I have execution_failure_criteria
set to not run on warning and critical, it seems freshness checks are still
performed. The good thing is this doesn't generate any alerts it just
clutters up the interface so if you are looking to see what's wrong in the
web gui you see lots of warnings associated with it when really the agent is
just down and we were already notified of that. So it would be nice if you
could have a setting that would tell it that freshness checks should be treated
the same way as active checks.

I've started playing with making a bunch of dependencies and at first it

added one service to be dependent on the other one, but it seems that the

define service {
service_description base_log_checks
servicegroupsbase_service_group
hostgroup_name base_windows_2003
use generic-passive-service
check_freshness 1
freshness_threshold 3600

define servicedependency {
service_description nagios_cron
dependent_service_description base_log_checks
execution_failure_criteria w,u,c
notification_failure_criteria w,u,c
inherits_parent 1
}
What appears to happen is that I kill nsclient so nagios_cron starts
reporting stale at 3000 seconds, and the same for base_log_checks shortly
after. Then about every hour I get more stale soft alerts, and then after
the third try it goes to a HARD alert and I still get a ticket, though I'm
not sure why it's even checking if execution should be disable when
nagios_cron is in a warning state. But not only does the active checks
(service_is_stale) get executed but I'm also still getting notifications sent
after 3 attempts, so it doesn't really appear to be doing anything.
Unfortunately right now these servers are so busy it's hard to put them in
debug mode. Have I missed something obvious with these?
I must say though, with the size of your environment, it's quite possible that
just looking up the dependency takes longer than it does to just execute the
extra check. If you're looking to save time, that might well bite you in the
ass. It's something that will probably be improved til Nagios 4, but it will
require a change in Nagios' object structure, so we can't really do it without
upping the major version number :-/
