do you happen to have experience with setting up influxdb and telegraf? or maybe something else that might be better suited?

the metrics are currently in prometheus metrics format and scraped every 5 minutes.

my idea was to keep the current retention for most metrics and have longer retention (possibly with lower granularity for data older than a month).

the current prometheus setup is super simple, you can see (and older copy of) the config here.

if you want to build a configuration for influxdb/telegraf that i can more or less just drop in there without too many adjustments that would certainly be welcomed.

the metric that would need longer retention is lemmy_federation_state_last_successful_id_local.
