Programming Jabber

Monitoring and Troubleshooting the Server

We’ve already seen a glimpse of the configuration relating to logging of messages in the previous section. As standard, the Jabber server configuration describes two types of logging record and a recipient file for each type:

Error logging

Error log records are written to error.log in the current directory, as determined thus:

<log id='elogger'>
  <host/>
  <logtype/>
  <format>%d: [%t] (%h): %s</format>
  <file>error.log</file>
  <stderr/>
</log>

Statistical logging

Statistical log records used for tracking purposes are written to record.log in the current directory, as determined thus:

<log id='rlogger'>
  <host/>
  <logtype>record</logtype>
  <format>%d %h %s</format>
  <file>record.log</file>
</log>

Log records of this type are written when a client connects to the server and when a client disconnects.

Furthermore, we can use the debugging switch (-D) when we start the server and have debugging and trace output written to STDERR.
