Are you sure your nagios binaries have been stripped? > $ ls -lh /usr/src/nagios-3.0.1-cvs/base/nagios /usr/local/nagios/bin/nagios > -rwxrwxr-- 1 nagios nagios 1.5M 2008-05-06 11:15 /usr/local/nagios/bin/nagios* > -rwxr-xr-x 1 user user 2.1M 2008-05-06 10:08 > /usr/src/nagios-3.0.1-cvs/base/nagios* > $ file /usr/src/nagios-3.0.1-cvs/base/nagios /usr/local/nagios/bin/nagios > /usr/src/nagios-3.0.1-cvs/base/nagios: ELF 32-bit LSB executable, Intel > 80386, version 1 (SYSV), dynamically linked (uses shared libs), not stripped > /usr/local/nagios/bin/nagios: ELF 32-bit LSB executable, Intel > 80386, version 1 (SYSV), dynamically linked (uses shared libs), stripped The memory and processor (system time) is directly related to the size of the running process (which includes executable image size). Every time Nagios executes a check it has to fork two or three times (depending on configuration) and the kernel has to map/copy the executable memory for the new processes. Performance degradation can become even worse on systems that does not support copy-on-write for forked processes as they perform a full copy of the process memory during forks only to free it seconds later. - -- Thomas -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFJ42Sl6dZ+Kt5BchYRAkMpAKCZTMJLOmfelHxjRfwOcV3qfYyrIACeMwaC 8u+QBWjmHfSjOvcYg3pQhK4= =pL0b -----END PGP SIGNATURE----- ------------------------------------------------------------------------------ This SF.net email is sponsored by: High Quality Requirements in a Collaborative Environment.
