I'm using Pushgateway with Prometheus and everything is OK but after a couple of weeks Pushgateway collapses ... giving it a look there are tons of metrics that are not used anymore and delete them manually is practically impossible ... so ->
There is a way to expire Pushgateway metrics with a TTL or some other retention settings like by size or by time ? ... or maybe both ?
NOTE: I read at the mailing list of Prometheus a lot of people requiring something like this from one year ago or more ... and the only answer so far is -> this is not the Promethean way to do it ... really ? ... common, if this is a real pain for a lot of people maybe there should be a better way (even if it's not the Promethean way)
