I use the infinity-datasource to fetch CSV data (time column and count column). This data is correctly shown in the dashboard. Now, I want to add an alert if the count column exceeds the threshold. I created an alert rule with exact the same properties as in the dashboard, removed the “time” colum…

Ok, thanks for all the help. I now think I ran into a strange Grafana bug because the existing alert rule does not work. I created an identical new rule with exact the same settings (I even asked to collegues to cross check). The new one does show data, whereas the old one seems to be broken beyond…

Thanks @yesoreyeram for the quick reply. I reviewed your link, but sadly it does not work: I set up everything in Explore (like in your screenshot, and it shows the data). My use case: I want to setup an alert if there is any entry in the last 5 minutes having value > 40. I came up with this in E…

As seen in the first screenshot of my second post in this thread, I already do define the one column as Number (I also define it in the alert rule, even if the second screenshot does not show it. I removed the control in order to get the whole screen onto…

Your message helped me fix my issue: using Grafana v10, when creating the rule based on the panel using Infinity, the Alert preview always show “No Data”. I had to go into the Alert rules window and click on “New alert rule” from there. Using exactly the same parameters, I finally have data.
