There is not any way to push events from FusionAuth to a system like pagerduty, except those outlined by the webhook docs which are less system level and more app level.
If you are monitoring using systems like opsgenie, you can pull data from several different sources:
There's the system status endpoint, which can be polled. Before 1.19, it was binary (200 is good, anything else is bad) but now with 1.19 there are defined status codes: https://fusionauth.io/docs/v1/tech/apis/system#system-status This is the single best endpoint for a healthcheck. If you want to ingest system logs so they can be searched/scanned, you could set up a job to export the system logs: https://fusionauth.io/docs/v1/tech/apis/system#export-system-logs and process them (that that doesn't work for container based systems, see the docs for more). These logs are what you'd see if you were running fusionauth in docker and looking at STDOUT (so system level stuff). You can write your own scripts against the API to test for certain use cases ("Can this user login?", "Can this user register?") There's an event log which captures, well, system events, which can be accessed via the API: https://fusionauth.io/docs/v1/tech/apis/event-logs There is also the audit log, which is probably not what you are looking for, because that is less system level and more 'in app' events, with admin level actions being written (see also this issue). But it can be read via API: https://fusionauth.io/docs/v1/tech/apis/audit-logsIf you are running in Fargate, k8s or another container based system, your best option is to write something to pump the logs through a stream which you can then process for interesting/problematic events.
