Create an example Alert Escalation for scaling down a Server Array.
Table of Contents
Get a quick synopsis of Alert Escalations (and other types of alerts with respect to the RightScale Dashboard) here.
Go to Design -> Alert Escalations and click New.
Provide the following information for each alert escalation.
The next step is to define what actions should be taken when an alert escalation is called. The most common actions are already configured for your convenience. Under the Actions tab, select which action you would like to add. See Valid Actions for Alert Escalations for a detailed breakdown of each supported action. Add as many actions to an escalation as necessary. For example, you can create a series of actions to define an escalation process for a persistent problem.
Note: The 'vote_grow_array' and 'vote_shrink_array' actions will soon be deprecated. To set up autoscaling, please use tags instead. See Set up Autoscaling using Voting Tags.
In the example below, an email will be sent every 15 minutes to the system administrator. If the condition continues to persist without change for 60 minutes, the next action will be triggered (Ex: An email to the CEO).
In the examples above, the alert action was to send an email. Relaunching a server is among several other possible alert actions. The following discussion details how the Dashboard has embedded intelligence so that you don't try to relaunch a Server with missing Inputs.
When adding a "Relaunch Server" action to an Alert Escalation, there is a check to see if this escalation is connected to a server with missing Inputs. If so, a warning will be displayed to inform the user that in order to automate the relaunching of a server, its Input parameters must be fully specified. A warning message will appear when the input's check fails when clicking adding the 'relaunch_server' action.
Similarly, when adding an Alert Specification to a Server or ServerTemplate, there is a check to see if the Server (or a Server derived from a ServerTemplate) has missing Inputs. If so, a flash message is displayed to inform the user that in order to automate the relaunching of a server, its Input parameters must be fully specified. A flash warning message will appear when the Inputs check fails when clicking the "Attach" button from a selected Alert Specification (that includes a relaunch) from Manage -> Servers -> ServerName -> Alerts Tab
