Action Items

Action Items

Owner

Fix monitoring:

Alertmanager should send to #monitoring-prod rather than #monitoring?

Uptime robot didn’t report outage until keycloak was unavailable

Error messages need to be clear

Look at disk management

Decide on bigger disk?

Lessons Learned

  • If we want more sophisticated monitoring on services then we have to either see if the API for uptime robot will be able to support this or look at another product. API info here: https://uptimerobot.com/api/
