Set up alerting for ERROR logs from dialogue origins #815
Description
What happened?
My BALANCED_RTT PR contained a bug which caused pds-121981 requiring lots of manual bouncing of services to remediate. We should have been able to spot this very early on, because we were logging ERROR messages from the com.palantir.dialogue.core.RttSampler class, which have never been seen before.
Unfortunately, we didn't have any alerting on error logs from our libraries, so we didn't catch this until users reported an outage.
What did you want to happen?
Dialogue maintainers should get alerted when log.error messages come from our origins, even if they come from different products.
