Are you sure you've haven't got check_interval configured in the host directive, or inherited from the template being applied? The "active checks" setting does something different.
"check_interval" = how often to perform SCHEDULED host checks "active_checks_enabled" = whether or not Nagios executes a check when needed "when needed" can be be triggered by "host check_interval" or "service non-ok" With retention turned on, some settings are retained and thus ignore changes in .cfg files. For more detailed info, http://nagios.sourceforge.net/docs/2_0/xodtemplate.html#retention_notes NOTE: The retention notes specify that it only applies to settings changed during runtime, but I've seen cases where undefining a setting does not "clear" the setting if it's been set in the past through a .cfg file. For example enabling "flap detection" in .cfg, and then later not defining it in the .cfg left the host with flap detection enabled. > -----Original Message----- > From: Andy Shellam (Mailing Lists) > [mailto:[EMAIL PROTECTED] > Sent: Wednesday, November 08, 2006 2:45 PM > To: Tedman Eng > Cc: nagios-users@lists.sourceforge.net > Subject: Re: [Nagios-users] Using Nagios to monitor > "service-less" hosts > > > Ted, > > I've stopped Nagios, removed all ".dat" files from var, and > restarted it > - all checks are now pending. > However, I did look through retention.dat (I presume this is what you > meant - status.sav didn't exist) before I killed it, and the > check_interval parameter was not defined for any host. > > I would think, surely, "state retention" only retains the > service/host > check states so if, for example, the Nagios machine reboots, when it > comes back up it knows where it left off.
