Hi there, has any had got any experience of implementing prometheus metrics into Bloomreach.

Cannot seem to find much documentation about it at all.

Found this, https://github.com/prometheus/client_java however implemented the dependancies, probably in the wrong place, but not sure what file to add the servlet configuration…

Thanks in advance
John

Hi John,

I created this code repository a while ago https://github.com/bcanvural/brxm-jmx-prometheus-grafana-integration It uses the jmx exporter to expose jmx beans statistics to prometheus. For the jmx beans themselves check out this documentation page: https://documentation.bloomreach.com/14/library/concepts/web-application/jmx-management-beans-support.html

Hi there, just looking into some performance issues and wondered if this metric is zero

org_onehippo_hst_Caching_CacheHitRate

Is there something that needs to be configured?

We have added hst:cachble = true on the hosts nodes…??

thanks
J

Hi,

it is better to start a new topic rather than ask a question in an old one. Sorry, I don’t have an answer for this right now. Doesn’t seem like 0 is the number you are aiming for, but likely indicates a failure in reporting than actually having a 0 cache hit rate.
