PDAgent

[matson-itops]

want to use PDAgent with RHEL9 and Nagios2026R1.4
however, seeing it requires python2

anyone have advice on how to accomplish this?
Obviously I will check on PagerDuty side.

Hi @matson-itops,

Thanks for reaching out. After doing a bit of research, I would definitely contact PagerDuty. Python 2 was EOL in 2020, so they should have a modern solution by now.

After a few discussions with the "robot", it provided these suggestions, which may or may not be useful.

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.
GitHub - martindstone/PDaltagent
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.

Let us know if you find a workable solution.

What are the potential risks of using curl to send events directly to PagerDuty instead of using pdagent?
How can we ensure that the events are sent securely and reliably?
Thank you
