I'd like to parse some custom (network appliance) syslog files to create my own formatted output.
As I am new to syslog-ng & patterndb I have been trying to build an example using the documentation - my work so far is here: https://gist.github.com/linickx/8002981
In the example, I would like to read the syslog file (testfile.log):
Accepted password for sampleuser from 10.50.0.247 port 42156 ssh2
Accepted password for user from 10.51.0.27 port 4256 ssh2
And output just a list of usernames & ip addresses, like:
sampleuser; 10.50.0.247;
user; 10.51.0.27;
To parse the log file I have created the following patterndb (example.xml):
<patterndb version='4' pub_date='2010-10-17'>
<ruleset name='ssh' id='123456678'>
<pattern>ssh</pattern>
<rules>
<rule provider='me' id='182437592347598' class='system'>
<patterns>
<pattern>Accepted @ESTRING:SSH.AUTH_METHOD: @for @ESTRING:SSH_USERNAME: @from @ESTRING:SSH_CLIENT_ADDRESS: @port @NUMBER:SSH_PORT_NUMBER:@ ssh2</pattern>
</patterns>
<examples>
<example>
<test_message program="ssh">Accepted password for sampleuser from 10.50.0.247 port 42156 ssh2</test_message>
<test_values>
<test_value name="SSH.AUTH_METHOD">password</test_value>
<test_value name="SSH_USERNAME">sampleuser</test_value>
<test_value name="SSH_CLIENT_ADDRESS">10.50.0.247</test_value>
<test_value name="SSH_PORT_NUMBER">42156</test_value>
</test_values>
</example>
</examples>
</rule>
</rules>
</ruleset>
</patterndb>
However when I use the SSH_USERNAME & SSH_CLIENT_ADDRESS variables in my syslog-ng.conf
destination test_output {
file("/home/nick/output.log"
template("${SSH_USERNAME}; ${SSH_CLIENT_ADDRESS}; \n")
template_escape(no)
);
};
--[ full version can been seen in the GIST ]--
The output file (output.log) is empty

Is there some hierarchy or special way to use custom or patterndb variables in syslog-ng.conf that I am missing?
Thanks in Advance!
