Need help with trigger expression for web.test.fail

[vic]

The only reference to that trigger expression in the documentation is.

{host: web.test.fail[Scenario].last(0)}#0

I am using that trigger expression to cause an action to restart Apache which I have working. However, sometimes the website doesn't need an Apache restart and is just momentarily busy.

I can increase the timeout but I also want to have it only trigger if it failed for 5minutes (5x60seconds per test). Just like the host unreachable expression.

{Template OS Linux:agent.ping.nodata(5m)}=1

There doesn't seem to be any equivalent for web.test.fail. As far as I can tell it returns a 1 or 0 and not nodata. So I think I need something that says if 1 for 5min then 1 otherwise 0.

Why don't you use the .count function.

Or use the calculate item and trigger on calculate one (not for web.test.fail trigger).

Thanks for the suggestion. This seems to work exactly the way I want.

{host: web.test.fail[Scenario].count(300,1)}>4

UPDATE: Spoke too soon. Doesn't work. I think the reason is because it takes a little more than 300 seconds for 5 samples. Changing the 4 to a 3 or increasing 300 to something like 350 would probably work. I ended up using SUM instead which is more straight forward and has definitely been working for several hours now.

{host: web.test.fail[Scenario].sum(#5)}>4
