i'm confused as to why excision is not taking effect after several hours :thinking_face:

devth19:08:08

it's a small db, and the same procedure worked on another similar-sized db in another env

devth21:08:05

finally took effect about 4 hours later. this is on a db with about 6000 entities.

favila02:08:09

Excision takes place during the next reindex iirc

favila02:08:10

Reindex triggered by size of not-yet-indexed stuff. So may take a while on small/low volume db

this was asked a few months ago, but has anyone done any work on a datomic prometheus exporter, or have examples of other metric exporters you built?

matthavener19:08:00

devth: the javaagent and a default prometheus config works fine, but you can’t get any of the native datomic metrics out, just jvm metrics 😞

matthavener19:08:47

hm, I take that back, I suppose you could hook into prometheus with the callback system

devth19:08:02

yep, so maybe a lib that wraps jmx_exporter?

devth19:08:26

i'm thinking about hooking up a timbre logging callback just so i can at get some basic visibility on the metrics

matthavener20:08:22

+ prometheus client lib

matthavener20:08:29

should be fairly straightforward

devth20:08:38

thanks. checking it out

devth21:08:37

threw this together to get some quick visibility into metrics via logs https://github.com/devth/timbre-datomic-handler
