Hi, I'm Ryan

What we'll cover

What is logging?
The importance of time
Log management workflows
Some lessons we've learned

Big Data!

Tiny Devices!

The two types of logs we care about

Debugging = hardware, software

Data = what's being measured, acted on

What's a log?

[ timestamp ] + [ data ] = 1 log entry

Examples:

$tail /var/log/authd.log

Oct 20 09:11:44 Ryans-MacBook-Pro-2.local com.apple.authd[35]: Succeeded authorizing right 'com.apple.ServiceManagement.daemons.modify' by client '/usr/libexec/UserEventAgent' [11] for authorization created by '/usr/libexec/UserEventAgent' [11] (12,0)

[ timestamp ] + [source] + [pid] + [ message ]

$tail /var/log/ppp.log

Sat Feb 15 18:32:24 2014 : Connection terminated.

[ timestamp ] + [ message ]
