Plugin hangs on startup #55

Closed adam-bloom closed 2 years ago

adam-bloom commented 7 years ago

Using the latest version, I frequently find that the plugin simply hangs. My collectd config:

  LogTraces true
  Interactive false
  Import "collectd_rabbitmq.collectd_plugin"
  <Module "collectd_rabbitmq.collectd_plugin">

    Username "guest"
    Password "guest"
    Realm "RabbitMQ Management"
    Host "localhost"
    Port "15672"

  </Module>
</Plugin>

And the resulting log:

[2017-03-31 16:40:50] plugin_load: plugin "python" successfully loaded.
[2017-03-31 16:40:51] plugin_load: plugin "write_log" successfully loaded.
[2017-03-31 16:40:52] Initialization complete, entering read-loop.

When I compiled collectd with debug enabled, it would log one additional line before hanging:

[2017-03-30 20:22:03] Getting info for http://localhost:15672/api/nodes

A curl to that route returns successfully (and very quickly!), yet the collectd plugin simply hangs. Any ideas? I can get it to error (say, put the wrong username in the config), but can't get it to repeatedly behave properly. It has worked a handful of times, but I can't consistently reproduce that.

That is strange. collectd is pretty good about not letting plugins hang. I will see if I can recreate the plugin hanging.

I have tried a number of times to reproduce.. and I can't. What OS, rabbitmq, and collectd version are you running ?
