AWS Systems Manager Monitoring
AWS Systems Manager - Overview
AWS Systems Manager is a management service that helps you automatically collect software inventory, apply OS patches, create system images, and configure Windows and Linux operating systems. It provides centralized operational visibility and control over your AWS infrastructure through features like Run Command, State Manager, and Patch Manager, enabling you to manage resources at scale.
Monitoring AWS Systems Manager is essential for maintaining the reliability and efficiency of automated operations across your managed instances. Applications Manager's AWS Systems Manager monitoring tool provides real-time tracking of key parameters such as command execution status, delivery timeouts, and managed instance counts, helping administrators quickly identify and resolve command failures and delivery issues across their fleet.

Monitored parameters
Go to the Monitors Category View by clicking the Monitors tab. Click on the Systems Manager (SSM) instance available under Amazon in the Cloud Apps section. Displayed is the AWS Systems Manager bulk configuration view distributed into three tabs:
- Availability tab shows the availability history for the past 24 hours or 30 days.
- Performance tab shows health status and events for the past 24 hours or 30 days.
- List view tab enables you to perform bulk admin configurations.
By clicking a monitor from the list, you'll be taken to the AWS Systems Manager dashboard which includes the following tabs:

Note:
- The command history shown here is provided by AWS and may not always match exactly what you see in the AWS Console. In some cases, AWS may return only recent command history, so older commands may not appear here.
- The Active Commands metric reflects only commands currently in the Executing stage, captured exclusively during the monitor's polling cycle. Any commands initiated prior to the poll are not considered.
