Monitoring FFmpeg transcoding workers with Netdata

Help
1

Hi everyone, I run a few servers that transcode user-uploaded videos with FFmpeg, driven by a PHP queue. I’d like Netdata to alert me when a worker is stuck (100% CPU for a long time but no output growth) or when the queue backs up. Is the apps.plugin per-process view the right way to track FFmpeg processes, or would you write a custom collector reading the queue length from Redis? Any example alert configs would be really helpful. Thanks!
