ApsaraVideo Media Processing:Configure alert rules for an MPS queue

Configure alert rules by using CloudMonitor

Background information

The monitoring feature of MPS allows you to query the metric data about system performance and resource usage. You can also create custom alert rules to monitor service stability and analyze resource usage to detect and diagnose issues at the earliest opportunity. For more information about alert rules and how to configure alert contacts and alert contact groups, see Overview and Create an alert contact or alert contact group.

Metrics

Procedure

1. Log on to the MPS console.

2. In the left-side navigation pane, choose Global Settings > MPS Queue and Callback.

3. On the MPS Queue and Callback page, click Set Alarm Rule. The Alert Rules page appears.

   If you configure alert rules for an MPS queue for the first time, a service-linked role is automatically created for CloudMonitor and a message appears. Click Confirm. If you have created a service-linked role for CloudMonitor, ignore the message.

4. On the Alert Rules page, click Create Alert Rule.

5. In the Create Alert Rule panel, configure parameters. The following table describes the parameters.

   Parameter	Description
   Product	The service for which you want to create an alert rule. Select ApsaraVideo for Media Processing from the drop-down list.
   Resource Range	The range of the resources to which the alert rule applies. Valid values: All Resources: The alert rule applies to all resources of the specified cloud service. Application Groups: The alert rule applies to all resources in the specified application group of the specified cloud service. Instances: The alert rule applies to the specified resources of the specified cloud service.
   Rule Description	The content of the alert rule. The parameters in this section specify the conditions that trigger an alert. To specify conditions, perform the following steps: Click Add Rule and then select Simple Metric, Combined Metrics, Expression, or Dynamic Threshold. In the Configure Rule Description panel, configure the rule name, metric type, metrics, threshold, alert level, and notification methods. Click OK. Note For more information about how to specify complex alert conditions, see Alert rule expressions.
   Mute For	The interval at which alert notifications are sent. If the alert does not return to normal after the alert is triggered, CloudMonitor can send an alert notification again. Valid values: 5 Minutes, 15 Minutes, 30 Minutes, 60 Minutes, 3 Hours, 6 Hours, 12 Hours, and 24 Hours. If a metric value reaches the threshold, CloudMonitor sends an alert notification. If the metric value reaches the threshold again within the mute period, CloudMonitor does not resend an alert notification. If the alert is not cleared after the mute period ends, CloudMonitor resends an alert notification. For example, if the Mute For parameter is set to 12 Hours and the alert is not cleared, CloudMonitor resends an alert notification after 12 hours.
   Effective Period	The period during which the alert rule is effective. The system monitors the metrics and generates alerts only during the effective period.
   Alert Contact Group	The alert contact groups to which alert notifications are sent. The alert notifications of the application group are sent to the alert contacts that belong to the selected alert contact groups. An alert contact group can contain one or more alert contacts. For more information about how to create an alert contact and an alert contact group, see Create an alert contact or alert contact group.
   Alert Callback	The callback URL that can be accessed over the Internet. CloudMonitor sends HTTP POST requests to push alert notifications to the specified URL. Only HTTP requests are supported. For more information about how to configure an alert callback, see Use the alert callback feature to send notifications about threshold-triggered alerts. Note You can click Advanced Settings to configure this parameter. To test the connectivity of an alert callback URL, perform the following steps: Click Test next to the callback URL. In the Webhook Test panel, you can check and troubleshoot the connectivity of the alert callback URL based on the returned status code and test result details. Note To obtain the details of the test result, you can configure the Test Template Type and Language parameters and click Test. Click Close.
   Auto Scaling	If you turn on Auto Scaling, the specified scaling rule is enabled when an alert is triggered. In this case, you must configure the Region, ESS Group, and ESS Rule parameters. For more information about how to create a scaling group, see Manage scaling groups. For more information about how to create a scaling rule, see Manage scaling rules. Note You can click Advanced Settings to configure this parameter.
   Log Service	If you turn on Log Service, the alert information is written to the specified Logstore in Simple Log Service when an alert is triggered. In this case, you must configure the Region, ProjectName, and Logstore parameters. For more information about how to create a project and a Logstore, see Getting Started. Note You can click Advanced Settings to configure this parameter.
   Simple Message Queue (formerly MNS) - topic	If you turn on Message Service - topic, the alert information is written to the specified topic in Simple Message Queue (formerly MNS) (SMQ) when an alert is triggered. In this case, you must configure the Region and topicName parameters. For more information about how to create a topic, see Create a topic. Note You can click Advanced Settings to configure this parameter.
   Method to handle alerts when no monitoring data is found	The method that is used to handle alerts when no monitoring data is found. Default value: Do not do anything. Valid values: Do not do anything Send alert notifications Treated as normal Note You can click Advanced Settings to configure this parameter.
