7.3. Change Broker Logging Time Resolution

Procedure 7.1. Change Resolution Logging on a Running Broker

1. Edit the file /etc/qpid/qpidd.conf and add the following:

   log-time=1
   log-enable=info+
   log-to-file=/var/lib/qpidd/771830.log

   Copy to Clipboard Toggle word wrap
2. Launch qpid-tool.
3. Now that you are running qpid-tool, issue the following command:

   list broker

   Copy to Clipboard Toggle word wrap
   You might have to do this a few times before receiving an answer. It can take a while to get all the info from the broker.
4. When you see a response similar to this:

   114  14:03:39  -          amqp-broker

   Copy to Clipboard Toggle word wrap
   Use the number (in this example "114") to refer to the broker.
5. Issue the following command, substituting the appropriate number for your broker:

   call 114 setLogHiresTimestamp 1

   Copy to Clipboard Toggle word wrap
6. Now look at the log file /var/lib/qpidd/771830.log and verify that it has started using highres time stamps. You might need to do something to get the broker to log a few more lines, for example start another qpid-tool.
7. To return the logging to the normal resolution, issue the following command in qpid-tool:

   call 114 setLogHiresTimestamp 0

   Copy to Clipboard Toggle word wrap
8. Now look at the logfile again, and verify that it has stopped using highres.
