Server disappearing

[kdimail]

Hello Statusmap Plugin Team.
I faced into the strange behavior of Statusmap/Grafana.
If I have some problematic server, after period of time it disappears from the dashboard but AFTER fixing it I see timeline on the Statusmap in red (downtime) and again green color.
My question is: how can I configure Statusmap/Grafana/Prometheus (I really did not find where is it) for actual/real view and not "customized"? I mean - if I have some problem with the server I want to see it ALL TIME in red till resolved problem otherwise I do not know what incidents I have because I do not see them online. Thanks.

Hello! Plugin can't display something without data. Let's find out if you need more queries or just change plugin settings. Please give more information: screenshot without failed server, screenshot with restored server, plugin settings, datasource queries and responses.

There is an example setup for Prometheus https://github.com/flant/grafana-statusmap#prometheus

Unfortunately I really do not understand what exactly I should do. I've read (before) this README a couple of times but because of coffee maker example I do no see how to config in my case.

That example uses advanced techniques to get correct data from Prometheus (max_over_time, count, record rules). It is better to use them to eliminate false positives and data loss.
The main idea is to create queries to have 0 and 1 for each possible status (0 and 1 for status 0, 0 and 1 for status 1, 0 and 1 for status 2, and so on).

In case you just explore a new plugin I think you can use up == bool 1 for simplicity. This query returns 1 for timestamps when up is 1 and 0 for timestamps when up is not 1. See https://prometheus.io/docs/prometheus/latest/querying/operators/#comparison-binary-operators

Thank you so much for your patience and answer!
I've been searching for weeks (!) for the solving my problem.
Have a perfect day!

Hello. I have a question: how can I reduce to server name only ALL the description that Statusmap takes from the Prometheus config file. Is there some custom display templates or something like that? Thanks.

Statusmap takes nothing from the Prometheus configuration. Please, create new discussion with more details.
