I have active host checks set to 0 so that they won't actually check unless a service fails on the host. How do you specify a recheck in seconds? I thought minutes were all that was allowed.<br><br>-Blake<br><br><div><span class="gmail_quote">

had large latencies caused by (1) hosts being down and (2) a host check that
took way too long. Nagios will suspend all service checks while it performs a
host check. In my case, the Nagios config I inherited made 10 attempts at 30
seconds each attempt before declaring a host to be down, so if one host went
down, the host check took 300 seconds. I typically have 15 hosts down out of
475. I changed my host checks to 3 attempts at 6 seconds each, and
latencies went way down.</span></font></div>
