If I have 1 synthetic monitor with 2 or more http requests, I would like to be able to only generate a problem if all fails, because they are part of a loadblancer, and I would like to get a warning if one of the requests fails.

example.

I have 3 urls:

> **[test1.com — slightly better than test2](https://test1.com)**
>
> test1.com — All your test are belong to us. Built for testing. Safe for demos.

[test2.com](http://test2.com)

[test3.com](http://test3.com)

If all 3 fails I would like a problem generated

If only 1-2 of the 3 fails I want to see it as a warning but not a problem as everything is still working.

As it is right now I can only do it on locations.

So can it be put as an enhancement request ?

Regards

Bjarne

Can you do what you want with [Custom events for alerting?](https://www.dynatrace.com/support/help/how-to-use-dynatrace/problem-detection-and-analysis/problem-detection/metric-events-for-alerting)

Create 3 separate HTTP Monitors.

1) For ‘warning’ when only 1 endpoint fails, use either the global or local outage settings in the HTTP Monitors. See [docs](https://www.dynatrace.com/support/help/how-to-use-dynatrace/synthetic-monitoring/browser-monitors/configure-browser-monitors#outage-handling).

2) For the All down problem, create a ‘custom event for alerting’. I tagged all three of my HTTP Monitors with ‘HMA’ and then used this metric expression to combine them.

builtin:synthetic.http.resultStatus:filter(and(eq(“Result status”,FAILURE),in(“dt.entity.http\_check”,entitySelector(“type(http\_check),tag(~“HMA~”)”)))):splitBy():count:auto:sort(value(avg,descending)):limit(100)

I then set the static threshold to alert when the count went over 2.
