Multiple checks before trigger activations

[Siegfried]

Hi,

I was wondering if there was a way to configure triggers so that the checks were performed more than 1 time before activating the trigger. As an example, if I look at the following trigger "WEB (HTTP) server is down on {HOSTNAME}", which has the following expression:

{Template_Linux:net.tcp.service[http].last(0)}=0

In the case of a failure on reaching port 80, is there a way to make sure that the check is performed 2-3 times before the trigger is activated? This is to avoid false positives in the case of network hickups. Also, is there a way to accelerate the checks during that time?

I'm curious because we're evaluating a switch from nagios and these are 2 very interesting features that we would almost certainly need.

Thanks!

Hi Siegfried
You can achieve this by using functions like min and max which take an argument that allows you to specify how many seconds an expression must be true until a trigger is fired.

{tmpl_environment:environment.temperature[0].min(620)}>27

Or alternatively you can put a # before the number to specify the number of values instead of the seconds.
{tmpl_mta_external:smtp_perf.max(#100)}=0
