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

Prerequisites​

Dependent Configuration​

To configure this O11ySource, create a 'credential' of type 'user' under the 'Definition' tab.

Inputs for Configuring Data Source​

  • Endpoint: Add the endpoint URL for the Storage Array
  • Endpoint URL: Add the endpoint URL for the Storage Array
  • Resource Path: The resource path, eg : /ecomconfig, /cimom
  • Device Type: Storage Array Vendor Name
  • Class Names: List the Class Names to be Monitored
  • Namespace: Mention the Namespace to be monitored
  • Polling Interval (in seconds): Time interval for polling data from the Storage Array endpoint 300 seconds – 3000 seconds.
  • Authentication Method: Select the Authentication Method
  • Credential: Credentials to access the storage Array endpoint

Firewall Requirement​

To collect data from this O11ySource, ensure the following ports are opened:

Source IPDestination IPDestination PortProtocolDirection
vuSmartMaps IPStorage System endpoint443*TCPOutbound

*Before providing the firewall requirements, please update the port based on the customer environment.

Configuring the Target​

Before configuring the O11ysource, ensure that:

The CIMOM server is running and accessible on the storage system Network connectivity exists between the vuSmartMaps Cluster and the storage system's CIMOM port For HTTPS connections, valid credentials are available. The required CIM classes exist in the specified namespaces on the storage system

Configuration Steps​

  • Enable the O11ySource.
  • Select the sources tab and press the + button to add a new instance that has to be monitored.
  • Provide the required configurations:
  • *Endppint URL
  • *Polling Interval (in seconds)
  • *Credential
  • *Resource type
  • *Device type
  • Click Save to close the data source window.

Metrics Collected​

The metrics are based on the input data collected.
