31 March 2014

Default Thresholds for Alerting Policies

We are now providing a suggested default threshold when you create a threshold alert policy for any metric.  These thresholds take into account the past behavior of the resources that you are setting up the metric. If you notice any suggestions that seem particularly wrong, let us know so that we can continue to improve the algorithm!

Endpoint Port Monitoring

Our uptime monitoring solution now supports the option for you to monitor UDP/TPC ports, in addition to the HTTP/HTTPS monitoring we supported already!  

To use it, simply select "Services" in the main navigation, and then "Endpoints" at the bottom of the Services menu to get to the endpoint listing page.  Click the "Add an Endpoint" link at the top of the list, and select "UDP/TCP" from the Endpoint Type select field at the top of the form.  Then simply choose a resource or group in our system...or enter a generic end point for us to check, enter the protocol and port to monitor, and tell us what text that should be expected in the response.   Then tell us how often to check for you...it's that simple!

28 March 2014

Alerting policies can now specify multiple conditions which define when an alert should be triggered. Conditions can be defined such that ALL or ANY must be met before triggering an incident. Elite customers can add up to 6 separate conditions to a policy.

Group Sampling
When alerting on groups, you can now specify what % (or #) of members of the group must be in violation. For example you can create a condition which triggers if only 30% or more of the group is in violation.

API Control
You can list, read, delete, pause, and resume policies through the API.

11 March 2014

Create Custom Graphs of Endpoint Latency

You can now create graphs on custom dashboards or group dashboards of the latency of endpoints monitored by Stackdriver.  Select the "Instance Endpoint" or "Load Balancer Endpoint" resource type.  You can then filter based on the resource that the endpoint is monitoring with the usual filters of name and group.

10 March 2014

Uptime Monitoring User Agent Change

Checks with Stackdriver's uptime monitoring feature now use a user agent of Stackdriver_terminus_bot(http://www.stackdriver.com) rather than a generic python/requests user agent.

5 March 2014

Partial API Support for Policies

Additional functionality is now available through the API.  Policies can now be put in maintenance mode, in the same way that instances can.  The API also allows the listing and deletion of policies.  Details can be found at http://docs.stackdriver.com/api .

4 March 2014

Change to Full-Screen mode for charts

Putting charts into "Full-Screen mode" used to both expand the chart to fill the browser window AND trigger the browser application to switch into "Full Screen mode" as well.  For some users forcing the browser application into Full Screen mode was undesirable.  We've changed the Full-Screen mode for charts to now expand to fill the current browser window area below the primary navigation, but it will no longer force the browser application into "Full Screen mode".

Charts in the new Full-Screen mode still behave as before (zoom, hover data-tips, etc.), but users will now continue to have access to all browser menus items, toolbars, and the Stackdriver application primary navigation at the top of the page.  Users can now navigate to other areas of the application without needing to exit the chart Full-Screen mode.

3 March 2014

Removal of Custom Metrics

For cases where you send a custom metric accidentally or to test the API, you can now schedule the removal those metrics so that they are not visible for creating custom graphs or alerting policies.  You can read the information on how to do this here

Group Criteria to Filter by VPC Subnet

You can now use VPC subnet as a criteria to filter on when creating a group.

Custom CloudWatch Metrics

Stackdriver now supports collecting custom metrics that you send to CloudWatch.  By default, any metric that is sent to CloudWatch with a namespace of Stackdriver is collected.  If you wish to collect additional namespaces, you can add them from your app settings.

Note that these metrics are treated the same as other custom metrics in Stackdriver.

19 February 2014

Alert Notifications via SNS

You can now use an SNS topic in your account as a target for alert notifications.  Set up the topic from settings and then select it just like you can any of email, SMS, PagerDuty, etc.  This allows another path to do custom handling of your alerts in a programatic fashion.

17 February 2014
