v1.3, June 14, 2012

New Features

• Traceroute API: This API lets you run a Traceroute from a Monitoring Zone to a Hostname or IP address. Like all Cloud Monitoring features, the Traceroute API is fully dual stack, supporting both IPv4 and IPv6. The Traceroute API can be used to debug networking issues between the Cloud Monitoring collectors and your infrastructure.

  Traceroute Docs

• Metric interpolation on the Alarm status string: This allows you to include metrics from a Check in the status string returned by an Alarm. For example, to include the HTTP status code from a remote.http Check, your Alarm could look like this:

  				if (metrics['code'] != "200") {
  					return new AlarmStatus(CRITICAL, 'Bad HTTP Status: #{code}');
  				}

  Alarm DSL Docs

• Add payload to the remote.http check: This allows you send a request body during a HTTP/HTTPS request.

  remote.http attributes

Enhancements

• Allow a user to specify the number of ICMP packets to send out on the remote.ping check.

• Updated Certificate Authority chain used to validate SSL certificates, resulting in less false positives.

• remote.tcp check now features the body_match_metric when specifying the send_body command.

• Add the remote IP address of the collector that alerted you to the Webhook notification payload.

Resolved Issues

• Fixed writable date and time fields that were supposed to be immutable.

• Fixed the DSL string escaping to allow you to specify special characters, example below:

  			if (metric['code'] nregex '2\\d\\d') {
  			  return new AlarmStatus(CRITICAL, 'Invalid status code #{code}');
  			}
