Alerting when a specific domain calls an unmonitored host


I have an unmonitored host, and I would like to be alerted when a specific URL tries to call this host.
I wonder if it's possible to do it with a rule or something.

There is no option for that by configuration only. You will need catch on this host such behaviour. On DT side you will need to create custom network device (for example using host name of this unmonitored one). Then you should pass those occurencies of calls as custom metric into dynatrace. On such metrics you can define custom thresholds. Then problem will be rised.

I fee your pain on this one. It's a hard one to find an easy answer to for both the customer and Dynatrace. I am still trying to figure out the best way to deal with unmonitored hosts. I might not be stating this exactly right, but from what I can tell Dynatrace treats "Unmonitored hosts" as one big service. The problem is unmonitored hosts can be connected to numerous applications, services, hosts, etc. from multiple teams who own different things. The 2 things we are trying to figure out are:

  • How do you break apart unmonitored hosts so that those specific entities are assigned to the correct owners rather than one single bucket if you will
  • Make it much easier to see what exactly the unmonitored host is that Dyntrace is talking about. It's often not clear what the unmonitored host even is so that I can see about licensing that end to get visability.

Actually I'm always splittiing unmonitored hosts into custom network device (now you can do it via UI). It is easier to tag it and assign to right management zone for example. But for the purpose @Bastien T. is talking about I have no clue... Maybe log analytics, writing such incidents into logs and creating alerts based on them?
