If something goes wrong and you can’t find out why it is not working as you expect you might want more detailed debugging options switched on.
Tigase is a Java application and it uses Java logging library this gives you flexibility to switch logging on for selected java package or even for a single Java class.
Logs files are stored in logs/ directory. tigase-console.log keeps all the data but only basic logs. tigase.log.N files keep all the detailed logging entries. So this is the place where you should look in case of problems.
The easiest way to change logging for the Tigase package is modifying in init.properies following line:
The line above says: "Switch on ALL debug messages for packet: tigase.server". The tigase.server packet keeps all component’s classes. So it allows you to monitor what is going on in each component. What packets it receives and what it is sending out.
Usually people want to see what is going on the network level. That is what has been sent and what has been received by the server - the actual character data. The class which would print all received and sent character data is: tigase.xmpp.XMPPIOService. To enable all debugging info for this class you have to modify the debug line:
Note, you skip the tigase. part.
You can also have debugging switched on for many packages/classes at the same time:
Other packages you might be interested in are:
tigase.cluster would print all the clustering related stuff. So if you have clustered installation you might be interested in debug settings:
and so on…
This method, however has 2 main disadvantages:
To enable logging for your own packages from packages different than tigase. you have to use another option which has been made available for this:
--debug-packages = your.com.package
You can also specify more parameters for the Tigase logging mechanisms like the file size, number of file rotated and location where all Tigase logs are stored. You have to include following lines in the init.properties file:
basic-conf/logging/java.util.logging.FileHandler.limit=100000000 basic-conf/logging/java.util.logging.FileHandler.count=20 basic-conf/logging/java.util.logging.FileHandler.pattern=/var/log/tigase/tigase.log
