Email error message using crashmail with supervisor

Question

I have a server with supervisor running an eventlistener, on the event when the process crashes, I managed to get crashmail to send an email to me. But the email content only states "Process adnode04 in group adnode04 exited unexpectedly (pid 1255) from state RUNNING".

I want crashmail to be able to take content from the last 10-20 lines of the log file and email me the contents. Is it able to do that?

Answer 1

Absolutely, but you will have to fork crashmail yourself.

The message is around line 112. You can use the XML-RPC API to call tailProcessStderrLog.

So what you'd basically do is add something like:

rpc = childutils.getRPCInterface( os.environ )
log = rpc.supervisor.tailProcessStderrLog( %(groupname):'%(processname)' % pheaders, 16000 )
msg += '\nLog:\n%s' % log['bytes']

The above is a simple proof-of-concept, untested and very probably contains a mistake. Let me know how it goes.
