Follow through this guide to learn how you can easily monitor Windows system metrics using Sensu. Sensu is an opensource infrastructure and application monitoring tool. You will learn to monitor such metrics as CPU usage, memory usage, disk usage etc.
Monitor Windows System Metrics using Sensu
Configure Sensu Agent Entity Subscription
As described in the guide below, you need to add the Windows system agent into a specific subscription;
Configure Sensu Agent Entity Subscription
sensuctl entity update WorkBox? Entity Class: agent
? Subscriptions: windows
Updatedsensuctl entity list

rocky8 agent linux linux,entity:rocky8 2022-05-07 20:02:13 +0000 UTC
Next, install Sensu Checks Plugins
As described in the guide below, install Sensu checks plugins;
Install Sensu Check Plugins on the Sensu Backend

Define Sensu Monitoring Command Checks
Next, Create Sensu Monitoring Command Checks.
Since we already defined the checks and define Subscription for Linux systems, you need to update these checks to be run against windows as well.
For example, to update the check_cpu check;
sensuctl check update check_cpuSample update prompts.
? Command: check-cpu-usage -w 80 -c 90
? Interval: 300
? Cron:
? Timeout: 0
? TTL:
? Subscriptions: linux,windows
? Handlers:
? Runtime Assets: check-cpu-usage
? Publish: true
? Check Proxy Entity Name:
? Check STDIN: false
? High Flap Threshold: 0
? Low Flap Threshold: 0
? Metric Format:
? Metric Handlers:
? Round Robin false
Updated
Update the rest or create new checks as you so wish;
This is how my checks look like;
sensuctl check list
Name Command Interval Cron Timeout TTL Subscriptions Handlers Assets Hooks Publish? Stdin? Metric Format Metric Handlers
───────────── ──────────────────────────────── ────────── ────── ───────── ───── ─────────────── ────────── ──────────────────── ─────── ────────── ──────── ─────────────── ──────────────────
check_cpu check-cpu-usage -w 80 -c 90 300 0 0 linux,windows check-cpu-usage true false
check_disk check-disk-usage -w 75 -c 85 300 0 0 linux,windows check-disk-usage true false
check_mem check-memory-usage -w 75 -c 90 300 0 0 linux,windows check-memory-usage true false
check_swap check-swap-usage -w 75 -c 90 300 0 0 linux check-memory-usage true false
The three checks have been defined to run against both Linux and Windows system subscription.
As you are done updating the checks, they should have been executed already.
Verify the event data;
sensuctl event list | grep WorkBoxSample output;
