Storage Monitor
Introduction
The Storage Monitoring Ollysource enables real-time collection of storage metrics from CIM/WBEM-compliant storage systems. This plugin connects to storage management interfaces (like HP 3PAR, Dell EMC PowerMax, and other SMI-S compliant storage arrays) to collect performance and capacity data.
Getting Started
Compatibility
This plugin supports monitoring of storage systems that implement the SMI-S (Storage Management Initiative - Specification) standard, including:
HP 3PAR Storage Systems Dell EMC PowerMax Dell EMC VMAX OpenPegasus CIMOM (for testing and development) Any SMI-S compliant storage array
Data Collection Method
The CIM Storage plugin collects data using the WBEM protocol over HTTP/HTTPS. The plugin:
Connects to the CIMOM server at configured intervals Enumerates CIM class instances from specified namespaces Extracts properties from each instance (capacity, performance metrics, identifiers, etc.) Converts the data into Telegraf metrics with tags for endpoint, namespace, class name, and instance identifiers Supports parallel collection of multiple classes for efficient data gathering
