- From my personal experience NRPE often fail on the SSL handshake under load - since it happen on the SSL part the connection is already open (therefore you can telnet to the port without any problem). I never really looked into issue because none of my servers runs hot - When I get NRPE timeouts there's usually other stuff that's sending alerts already (at least the load average check running trough SNMP). Things you may try: - - Lower the nice value of the NRPE process - - Disable SSL - - When compiling NRPE, in include/common.h, increase the socket timeout: #define DEFAULT_SOCKET_TIMEOUT 10 /* timeout after 10 seconds */ - - Increase the check_nrpe and/or nagios active check timeouts. - -- Thomas -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFJlu+e6dZ+Kt5BchYRAq6nAJ0boUmZyySZ7adQ8tBNtMhrcZQpogCgnbSu Mt/FbvA8GfzdMFig56KwBx0= =MQtG -----END PGP SIGNATURE----- ------------------------------------------------------------------------------ Open Source Business Conference (OSBC), March 24-25, 2009, San Francisco, CA -OSBC tackles the biggest issue in open source: Open Sourcing the Enterprise -Strategies to boost innovation and cut costs with open source participation -Receive a $600 discount off the registration fee with the source code: SFAD http://p.sf.net/sfu/XcvMzF8H _______________________________________________ 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
