After having it run overnight, average latency is .1xx seconds. For my base service template (all checks inherit from this and they do not override these attributes) I have obsess_over_service 0 normal_check_interval 5 retry_check_interval 5 max_check_attempts 3 > Are you using slow-running OCSP/OCHP commands?

Yes, I am using modpnpsender and a service performance data handler, but even with those commented out in the config I see the same results. This is a RHEL52 box running nagios 3.0.3, because of where it sits on the network I have had to manually add RPMs to the box to configure it .. I initially had glib2-devel and my perception was that performance was slow with that library being used so i took the devel package off of the host as most Linux hosts I have been on I have not had Nagios complied with glib2. As I look now at performance data again on Nagios with process_perfdata set to 0 and the PNP NEB module commented out (restarted Nagios about 10 minutes before starting this email) I am still only seeing 86% within 5 minutes, avg latency .22, for service checks and via top I am only see max 2 Nagios instances. With "top -i" I just see Nagios appear on and off occasionally. Maybe to test to see if there is something wrong with my compile I should turn down the check interval to 1 minute for checks to see if Nagios does what I would expect, constantly running checks to try and keep up? if it doesn't behave that way, would that be a relatively clear indication I have a compile issue? My configure options just in case something pops out that looks glaringly wrong, i don't expect anyone to go through them line by line :p: $ ./configure --prefix=/data/nagios --exec-prefix=/data/nagios --bindir=/data/nagios/bin --sbindir=/data/nagios/sbin --datadir=/data/nagios/share --libexecdir=/data/nagios/libexec --enable-event-broker --enable-embedded-perl --with-nagios-user=nagios --with-nagios-group=nagios --with-command-user=nagios --with-command-group=apache --with-mail=/bin/mail --with-httpd-conf=/etc/httpd/conf.d --with-checkresult-dir=/data/nagios/var/checkresults --with-temp-dir=/data/nagios/tmp --with-init-dir=/etc/init.d --with-lockfile=/data/nagios/var/nagios.lck --with-gd-lib=/usr/lib64 --with-gd-inc=/usr/include --with-cgiurl=/nagios/cgi-bin --with-htmurl=/nagios --with-perlcache uname -m = x86_64 uname -r = 2.6.18-53.el5 uname -s = Linux uname -v = #1 SMP Wed Oct 10 16:34:19 EDT 2007 Configured with: ../configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --enable-shared --enable-threads=posix --enable-checking=release --with-system-zlib --enable-__cxa_atexit --disable-libunwind-exceptions --enable-libgcj-multifile --enable-languages=c,c++,objc,obj-c++,java,fortran,ada --enable-java-awt=gtk --disable-dssi --enable-plugin --with-java-home=/usr/lib/jvm/java-1.4.2-gcj-1.4.2.0/jre --with-cpu=generic --host=x86_64-redhat-linux C=gcc CFLAGS=-g -O2 -I/usr/include -D_REENTRANT -D_GNU_SOURCE -fno-strict-aliasing -pipe -Wdeclaration-after-statement -I/usr/local/include -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -I/usr/include/gdbm -I/usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi/CORE -DHAVE_CONFIG_H LDFLAGS= -L/usr/lib64 Thanks again for your help, I seem to be in a rare situation here as searches for Redhat and Nagios and performance issues turn up very few hits :p, which lets me know I am definitely at fault here. - Max ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Nagios-users mailing list Nagios-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/nagios-users ::: Please include Nagios version, plugin version (-v) and OS when reporting any issue. ::: Messages without supporting info will risk being sent to /dev/null
