Peter Czanik: Syslog-ng 101, part 9: Filters
This is the ninth part of my syslog-ng tutorial. Last time, we learned about macros and templates. Today, we learn about syslog-ng filters. At the end of the session, we will see a more complex filter and a template function.
You can watch the video or read the text below.
Declaring filters
Filters are expressions to select, or in other words, filter log messages. They make sure that the right messages reach the right destinations. For example, you can use filters to discard debug level log messages, or make sure that all authentication-related messages are routed to your SIEM system.
A filter definition is a collection of one or more filter functions. It consists of two parts. It starts with the word “filter”, followed by an identifier for the filter which you will use later to refer to the given filter. After that, it lists the filter functions with their parameters. You can combine multiple filter functions using boolean operators. Here is how its syntax looks like:
filter name { filterfunction(); }; filter f_default { level(info..emerg) and not (facility(mail)); }; -
