7.3. Change Broker Logging Time Resolution
The time stamp resolution of logging can be changed while the broker is running.
Procedure 7.1. Change Resolution Logging on a Running Broker
- 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
- Launch
qpid-tool
. - Now that you are running qpid-tool, issue the following command:
list broker
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. - When you see a response similar to this:
114 14:03:39 - amqp-broker
Use the number (in this example "114") to refer to the broker. - Issue the following command, substituting the appropriate number for your broker:
call 114 setLogHiresTimestamp 1
- 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 anotherqpid-tool
. - To return the logging to the normal resolution, issue the following command in
qpid-tool
:call 114 setLogHiresTimestamp 0
- Now look at the logfile again, and verify that it has stopped using highres.
