Is there a way to debug the worker processes in pm2 while application is running in Cluster mode

Question

So I have a node.js application which I am running in cluster mode using pm2 . I am passing the following options for the web node in my pm2 schema.

exec-mode : "cluster"
--node-args : ["--inspect=5678"]

and for worker node I am passing following configuration

--node-args=["--inspect=5679"]

When I start my application in cluster mode , debugging is not possible as I cannot see the debugging URL printed in pm2 logs. Even if I send the USR1 signal to the web or worker node (as mentioned in node inspector help ), I do not see any way to debug the processes.

My guess is that in cluster mode , debugging node.js is not possible. I tried the same process with node-inspector but no luck yet.

将node_args作为字符串而不是数组传递（例如--node-args =“-inspect = 1234”）
