Monitor VM/OS conditions outside the scope of out of the box metric/properties

Products

• VCF Operations/Automation (formerly VMware Aria Suite)
• VMware Telco Cloud Platform

Issue/Introduction

Monitor VM state such as:

• Stuck in fsck
• In read-only state

Environment

Aria Ops, vROps: 8.18, 8.18.6

TCP: 5.0.2, 5.1

 

Cause

To automate the identification of these VMs, you can use the Telegraf agent to run custom scripts and report the filesystem health as a metric.

This concept revolves around a custom script that can provide a metric that can determine VM/OS states by testing for results such as:

• • Successfully write/touch a file
  • Successfully ping an address

This would prove that a VM has successfully booted and can write to a file system, providing you an indication if a VM is stuck needing an fsck or in a read-only state. 

Resolution

1. Deploy the Telegraf Agent

   • Configure the Telegraf agent on a Linux VM

   • Configure the Telegraf agent on a Windows VM

2. Create a custom script to monitor VM/OS conditions:
