topk(10, count by (__name__, job)({__name__=~".+"})) Unexpected Token

[Random Person]

Running into more OOM problems, and trying to use topk(10, count by (__name__, job)({__name__=~".+"})) . However the query always returns the following "Error executing query: Unexpected token i in JSON at position 1" . Is the only way to get data from this to increase query time limits ?

Thanks!

Hi,

That query itself should be ok, but if you get a JSON parsing error for the response coming back from Prometheus, that can indeed mean that your Prometheus died as a result of an OOM and whatever is in front of it returns invalid JSON in that case... probably no way to make it work without giving your Prometheus more memory, if that's the problem. Btw. you could switch '=~".+"' with "!=""' to get rid of regex matching, but that shouldn't make a difference.

Regards,

Julius
