But the host check becomes a problem: after first >PING failure (soft state) the host is checked, and there is no >retry_check_interval for hosts. So the host is declared to be down >(almost) immediately. I'm going to guess you're using nagios 2. Nagios 3 has a retry_interval for both service, and host. However, that being said, that just hints to me that the host check will be executed "max_check_attempts" at the "check_interval" rate (both options exist on a host). So set your max_check_attempts to a reasonible number (3 for 3 minutes for example), and check_interval to another reasonible number (1 for 1 minute), and that should handle 30 second "blips" in networks. - -- Jon Angliss -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (MingW32) - GPGshell v3.64 iEYEARECAAYFAkjkd6wACgkQK4PoFPj9H3P/bACdEPhfz6wPYCAqLpYHcU/wI7JZ OBgAoOqAadpvYuHSQbnGU5zHkbjl85TQ =jj8S -----END PGP SIGNATURE----- ------------------------------------------------------------------------- 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
