PromQL to identify targets which are failing continuously in last 5 minutes

[Narendra Gudipudi]

Hi,

I am using blackbox exporter to probe my targets. I am trying to write a PromQL to identify and alert every 5 minutes with details of targets which are continuously failing in the last 5 minutes. Any help here is greatly appreciated.

I run my probers every 1 minute;

9:00 AM

probe_success {url="https:/url1"} = 1

probe_success {url="https:/url2"} = 0

probe_success {url="https:/url3"} = 0

probe_success {url="https:/url4"} = 1

9:01 AM

probe_success {url="https:/url1"} = 1

probe_success {url="https:/url2"} = 0

probe_success {url="https:/url3"} = 0

probe_success {url="https:/url4"} = 0

9:02 AM

probe_success {url="https:/url1"} = 1

probe_success {url="https:/url2"} = 0

probe_success {url="https:/url3"} = 0

probe_success {url="https:/url4"} = 1

9:03 AM

probe_success {url="https:/url1"} = 1

probe_success {url="https:/url2"} = 0

probe_success {url="https:/url3"} = 0

probe_success {url="https:/url4"} = 1

9:04 AM

probe_success {url="https:/url1"} = 1

probe_success {url="https:/url2"} = 0

probe_success {url="https:/url3"} = 0

probe_success {url="https:/url4"} = 0

9:05 AM

probe_success {url="https:/url1"} = 1

probe_success {url="https:/url2"} = 0

probe_success {url="https:/url3"} = 0

probe_success {url="https:/url4"} = 1

I am looking for some help with query which gives me these two URLs -

https:/url2
https:/url3

as these were continuously failing in the last 5 mins.
