Parsing log file with logs of different patterns

Hi All,

I am new to logstash in that matter ELK stack. A log file is having different processes logging data to it. Each process writes logs with different patterns. I want to parse this log file. Each log in this log file is started with below grok pattern,
%{SYSLOGTIMESTAMP:timestamp} %{SYSLOGHOST:logsource} %{SYSLOGPROG}: + %{SRCFILE:srcfile}:%{NUMBER:linenumber}
where SRCFILE is defined as [a-zA-Z0-9._-]+

Please let me know how can I parse this file so that different type of logs from each process logging in this file can be parsed.

Thank You,

You can build out fully configured patterns to match against or do partial matches based on IF statements.
