Re: [Check_mk (english)] Ping Interval

Hi Jakes, Default interval is 60 seconds if you use the normal Nagios core. To get shorter intervals it is needed to change the default interval of the core. The next step is to change the default setting off PNP4Nagios to accept data with a shorter interval then 60 seconds. You see there is much

Create unique tags for those that require the -H and those that -I. Then have two rules for the active check, 1 for each. (I think) you can put $HOSTADDRESS$ in the 'use different IP" field and that should take effect to those hosts you specify by the tags, or folder. I do similar for HTTP and

What I need is to stagger the checks (you found the exact word I's was looking for!). The default time frame is OK for me, the real problem is that currently, once per day, a huge number of checks is activated *in the same second* and thus most of them are timing out. Unfortunately Implementing
