External Commands Reference - SCHEDULE_HOST_CHECK
Schedules the next active check of a particular host at ‘check_time’. The ‘check_time’ argument is specified in time_t format (seconds since the UNIX epoch). Note that the host may not actually be checked at the time you specify. This could occur for a number of reasons: active checks are disabled on a program-wide or service-specific basis, the host is already scheduled to be checked at an earlier time, etc. If you want to force the host check to occur at the time you specify, look at the SCHEDULE_FORCED_HOST_CHECK command.
#!/bin/sh # This is a sample shell script showing how you can submit the SCHEDULE_HOST_CHECK command # to Naemon. Adjust variables to fit your environment as necessary. printf "[%lu] SCHEDULE_HOST_CHECK;host1;1478648441\n" `date +%s` > /var/lib/naemon/naemon.cmd
