Let us know if you find a workable solution.1. Use the Events API v2 Directly
Since pdagent fails on RHEL 9 due to Python module issues, bypass it and use curl to send events:
curl -X POST "https://events.pagerduty.com/v2/enqueue" \
-H "Content-Type: application/json" \
-d '{
"routing_key": "YOUR_ROUTING_KEY",
"event_action": "trigger",
"payload": {
"summary": "Test alert from RHEL 9",
"severity": "critical",
"source": "RHEL9-Host"
}
}'
2. Use Alternative Tools
PDaltagent (GitHub): A high-performance, Python-based alternative that uses RabbitMQ for queuing and supports plugins. Runs well on modern systems.

Centreon Stream Connector: If using Centreon, integrates directly with PagerDuty via the Events API and supports RHEL 9.
3. Containerized Solutions
Run pdagent or custom alerting logic in a Docker container based on RHEL 8 or CentOS 7 to maintain compatibility.
