Create SLOs for Synthetic Browser Monitors Using DQL

robin_vogels — Thu, 18 Dec 2025 12:21:11 GMT

I would like to create a SLO for synthetic browser monitor duration < 2000ms. I successfully created a SLO for HTTP synthetic monitors, but I'm struggling to get the same working for synthetic browser monitors.

Can anybody help out?

@robin_vogels At what stage are you exactly facing issue when creating the SLO for HTTP synthetic monitors?

@p_devulapalli, I'm able to create the SLO with this DQL:

fetch dt.synthetic.events | filter dt.synthetic.monitor.id == "HTTP_CHECK-XXX" | makeTimeseries {total = count(), good = countIf(result.statistics.duration < 2000)} | fieldsAdd sli = 100 * (good[] / total[])

However when I try to to the same for a synthetic browser test I found out that these events are not stored in dt.synthetic.events, so I tried to get it working with dt.synthetic.browser.duration, but I'm not able to create a SLO for it.

Do you have any idea how to achieve this?

@robin_vogels Here is a example which is similar to what you are trying to achieve . You can try using dt.synthetic.browser.duration instead here , you can may be ignore the tags part and use dt.entity.synthetic_test to filter it down to the particular test you are after and the expressions

Hope this helps

Add ms:

fetch dt.synthetic.events | filter dt.synthetic.monitor.id == "HTTP_CHECK-XXX" | makeTimeseries {total = count(), good = countIf(result.statistics.duration < 2000ms)} | fieldsAdd sli = 100 * (good[] / total[])
