~ cat ./events.sh
#!/bin/bash
DSN_PUBLIC="<FIRST PART OF DSN, BEFORE @>"
SENTRY_HOST="http://<SENTRY HOST>"
PROJECT_ID="<NUMBER AT THE END OF DSN>"
curl -X POST --data '{ "exception": [{ "type": "Sentry curl test request", "value": "This is a test request to sentry sent by curl" }] }' \
-H "Content-Type: application/json" \
-H "X-Sentry-Auth: Sentry sentry_version=7, sentry_key=$DSN_PUBLIC, sentry_client=raven-bash/0.1" \

~ watch -n.3 ./events.sh- Configure sample alerts
- Number of errors
This will trigger as long as it is not edited when it is firing.
- Transaction Duration
This one will never fire, even when the condition is met.
Expected Result
Metric alerts should trigger.
Actual Result
I do not see anything useful in the logs, but I can provide them if requested. Pasting logs from all containers does not seem helpful.
On my deployed instance, I experience similar issues with other types of metric alerts, none of them are firing.
Event ID
No response
