Fixed crash on MySQL replication

1.13.3 (Jun 2 2014)

Added support for collecting meta data about attached persistent disks on Google Compute Engine.
Added automatic execution of mtr (if available) for traceroute collection when agent in debug mode.
Fixed RabbitMQ credentials leakage via other HTTP requests the agent might make and to the SD postback. Reported by Jesse Young.

1.13.2 (Jan 6 2014)

Added "ALL" aggregated CPU stats which helps with servers with many CPU cores so you can see averaged stats across all cores.
Added disk i/o stats on OS X
Added CPU stats on OS X
When there is an error in MySQL replication, MySQL reports the Seconds_Behind_Master status as NULL. This is now handled and reported as -1 to allow alerting.
Fixed bug with trying to process RabbitMQ stats when no config details present.
Disabled the recordStats output which was introduced in MongoDB 2.4 and causes a read lock, which can slow down agent execution and have an effect on the mongod server itself.
Fixed memory stats on OS X 10.9 Mavericks

1.12.4 (Mar 3 2013)

Fix debug logging being on by default

1.12.3 (Mar 3 2013)

Support for MongoDB 2.4 after a change in server output

Default to https in the config example url

1.11.4 (Jun 25 2012)

Added support for custom MySQL port and socket (see agent config options)
Added an option to disable MySQL replication checks to prevent verbose error logging (see agent config options)
Added authentication support for Apache status URLs (see agent config options)
Removed use of signal timeout handlers in most cases due to them causing more problems than they solve.
Improved some debug logging output.
Fixed a bug where the agent sees processes as bool, not list which could cause a crash.
Fixed a bug with handling unicode in the JSON payload when posting back
Fixed agent hanging when running disk usage check against a failed nfs mount
Handle TypeError for JSON serialization failures
Additional checks against negative Apache values
Fixed disk-usage check crashes agent when receiving unexpected values
Fixed issue with escaping process names
Fixed disk usage parsing doesn't gracefully deal with - instead of a number
Fixed memory statistics not correctly parsed on OS X 10.7.3
Fixed crash when server out of memory during CPU check

Note: The rpm package for RPM/CentOS was rebuilt as 1.11.4-3 due to a signing bug in the initial 1.11.4-1 release where the signature could not be read on CentOS 4 and CentOS 5. This was because we originally built the packages on CentOS 6, which uses version 4 of the gpg signing.
