smisarray

This is a generic python agent to collect inventory and performance data from any SAN Storage Array that support SMI-S and submit to FSM (Foglight™ for Storage Management).

Foglight™ for Storage Management provides complete monitoring of virtual storage environments, providing performance and capacity management metrics. It is designed for customers requiring storage monitoring functionality, but not full-fledged virtualization environment monitoring functionality.

What is SMI-S

The SMI-S, developed by the SMI organization of the SNIA, is an open standard used to manage storage networks of multiple vendors. The SMI-S defines a set of secure and reliable interfaces that help the storage management system identify, classify, and monitor physical and logical resources in a storage area network (SAN). Based on the existing technical standards, the SMI-S covers:

• Common information model (CIM) - The CIM is developed by a distributed management task force (DMTF) to describe concept models of data. The CIM uses a layered object-oriented system structure to model for managed resources. Devices and components can thus be described in an object-oriented manner.
• Web-based enterprise management (WBEM) - The WBEM is an enterprise-class management system structure developed by a DMTF. The WBEM assembles management protocols and standard Internet technologies for unified management in a distributed operating environment, improving data exchange capabilities across technologies and platforms.
• Service location protocol (SLP) - The SLP is used to discover the SMI-S server and its functions in a storage network environment.

As an open standard, the SMI-S expands general-purpose capabilities of the CIM, WBEM, and SLP to achieve interoperability in a storage network environment. For example, the WBEM provides security, resource lock management, and event notification.

Monitoring approach

During this procedure, you configure the agent to use SMI-S to collect from the Array Management Host that monitors the arrays.
To configure an agent to monitor the storage device:
1   On the navigation panel, under Dashboards, click the Administration tab.  
2   Click the Agents tab, then the Agent Status tab
3   Click Deploy Agent Package. 
4   The Storage Device Setup Wizard opens. Each of the following steps corresponds to one page in the wizard. Use the Next and Back buttons to navigate between pages. 
a   On the Select Host Selector page, select the Host to host this agent. 
b   On the Select Agent Packages page, select SMISStorageAgent. 
c   On the Agent Configuration Summary page, review the agent configuration. You can go back and make corrections, if necessary. 
d   Click Finish. 
5   Click Create Agent to open in the wizard
6   The Storage Device Setup Wizard opens. Each of the following steps corresponds to one page in the wizard. Use the Next and Back buttons to navigate between pages. 
a   On the Select Host Selector page, select the Host to host this agent. 
b   On the Select Agent Type and Instance page, select SMISStorageAgent. 
c   On the Agent Configuration Summary page, review the agent configuration. You can go back and make corrections, if necessary. 
d   Click Finish. 
7   Select the Agent to configure, click Edit Properties.
8   Click Modify the private properties for this agent.
9   Edit the User-defined Properties
    Host: ip of the SMI-S,default 127.0.0.1
    Port: port of the SMI-S, default 5989
    Username: the user of the SMI-S
    Password: the password of the SMI-S
10  Click Save.
11  Select the Agent that you want to activate
12  Click Activate.
