Creating Alerts for Servers, Server Groups, and Clusters

Configure proactive monitoring alerts for your hybrid standalone infrastructure to ensure optimal performance, detect issues early, and maintain system reliability across your distributed Mule runtime environment.

Overview

Runtime Manager provides comprehensive alerting capabilities for monitoring your hybrid standalone infrastructure, including:

Individual server health and performance monitoring
Server group coordination and member status tracking
Cluster connectivity and node health supervision
Resource utilization threshold monitoring (CPU, memory, load average, thread count)
Infrastructure lifecycle event notifications (connections, disconnections, deletions)

Runtime Manager retains 30 days of alert history for audit and analysis.

Alerts retrigger when conditions continuously exceed specified thresholds, ensuring persistent notification of ongoing issues.

Rate Limits on Alerts

Anypoint Platform enforces rate limits that determine how often an alert is triggered and prevent excessive emails from being sent. At present, there is no defined limit to the number of Runtime Manager alerts.

Create an Alert

Configure alerts to monitor your servers, server groups, and clusters with customizable thresholds and notification settings.

In Runtime Manager, click Alerts.
- If no alerts exist, you see the initial setup page:
  
  Figure 1. The arrow shows the Create your first alert option.
- For existing alert configurations, use the add button:
  
  Figure 2. The arrow shows the blue plus (+) icon on the Alerts page.
Click the blue plus (+) icon to create a new alert.
Complete the required fields:
- Name
  
  Unique and meaningful name for the alert
  
  The Name is limited to 256 characters.
- Severity level
  
  Severity of the alert: Critical, Warning, or Info
- Source
  
  The source of the alert: servers
  
  This field appears only if your Anypoint Platform account supports local servers.
- Server type
  
  When the source is Servers, the type of server: single server, server group, or cluster.
  
  If your servers aren’t available on your menu, see Servers, Server Groups, and Clusters.
- Servers
  
  The server to apply the alert to
- Condition
  
  The condition that triggers the alert
  
  The available options depend on whether your alert is linked to a server. Some conditions require additional data. See Alert Conditions.
- Subject
  
  The subject of the alert email to send when the alert is triggered
  
  The subject can include variables. See Alert Variables.
- Message
  
  The body text for the email to send when the alert is triggered. The message body can include variables. See Alert Variables.
- Recipients
  
  The recipients of the alert email
  
  You can select up to 20 platform user IDs and enter up to 20 email addresses.
Click Create Alert.

When an alert condition is triggered, Runtime Manager sends email notifications similar to this:

Anypoint Platform Alert Notification email

Alert Conditions

Configure specific conditions that trigger notifications based on your infrastructure monitoring requirements. Alert conditions range from simple status notifications to complex performance threshold monitoring.

Performance and Resource Monitoring

These performance alerts apply to all infrastructure types (servers, server groups, and clusters):

Server CPU Usage

Monitor CPU utilization across your infrastructure. Triggers when CPU usage exceeds the specified percentage for the configured duration.

Configuration: Set the CPU percentage threshold and monitoring duration.

Server Load Average

Monitor system processing load. Triggers when the average processing load exceeds the specified threshold for the configured duration.

Configuration: Set the load average threshold and monitoring duration.

This metric isn’t available on Windows environments.

Server Memory Usage

Track memory consumption across your infrastructure. Triggers when memory usage (in MB) exceeds the specified threshold for the configured duration.

Configuration: Set the memory usage threshold (MB) and monitoring duration.

Server Thread Count

Monitor JVM thread utilization. Triggers when the thread count exceeds the specified level for the configured duration.

Configuration: Set the thread count threshold and monitoring duration.

These alerts vary according to the target type (server, server groups, or clusters) and require no additional parameters:

Servers

Agent version changed
Runtime version changed
Server connected
Server deleted
Server disconnected

Server Groups

Server Group connected
Server Group deleted
Server Group disconnected
Server Group’s node connected
Server Group’s node disconnected
Server added to Server Group
Server removed from Server Group

Clusters

Cluster connected
Cluster deleted
Cluster disconnected
Cluster presents visibility issues
Cluster’s node connected
Cluster’s node disconnected
Server added to Cluster
Server removed from Cluster

Alert Variables

Customize alert email subjects and messages using dynamic variables that provide contextual information about triggered events.

You can’t use the character combination $& in variable expressions.
