parsing mysql query logs with logstash

The problem is that some lines in the file are missing timestamps when they aren't continuations of any previous line. It's dumb, really.

The mysql query log is seriously bullshit format, but nothing logstash can't unscrew.

The main goal here is to show how we can fix the 'missing timestamp' problem.

% ruby bin/logstash agent -e '

Opening and closing an SSH tunnel in a shell script the smart way

I recently had the following problem:

• From an unattended shell script (called by Jenkins), run a command-line tool that accesses the MySQL database on another host.
• That tool doesn't know that the database is on another host, plus the MySQL port on that host is firewalled and not accessible from other machines.

We didn't want to open the MySQL port to the network, but it's possible to SSH from the Jenkins machine to the MySQL machine. So, basically you would do something like

ssh -L 3306:localhost:3306 remotehost
