EMC Isilon Support in Foglight for Storage Management 3.1

With the launch of Foglight for Storage Management 3.1, we have added support for EMC Isilon storage arrays. In this BLOG, I’ll present some screenshots that illustrate the information that we’re able to collect.

Foglight for Storage Management collects from Isilon arrays using the Command Line Interface (CLI) embedded in the Isilon OneFS operating system. A single agent will collect from all of the nodes that belong to a specific array.

From the “Summary” tab, we can quickly ascertain the health of each of the subcomponents that make up this Isilon array by reviewing the “Related Inventory” section. It tells us how many of each subcomponent are present and the alarm status (good, warning, critical, or failure) of each. We also get a summarized view of total and free storage capacity that is broken down into traditional hard disk drives (HDD) and solid state drives (SSD). Finally, we display some select array-wide performance metrics such as average CPU busy, file system throughput, and number of clients.

From the “Network” tab, we can easily summarize network load and packet error rates across all outwardly facing Ethernet ports and inwardly facing InfiniBand ports. And we get detailed performance and health statistics for every network port in the array. Alternate views can filter the results to only show ports belonging to a specific member node.

The “Member Nodes” tab lists the top 5 nodes in terms of data rate, disk latency, and CPU busy. And it provides detailed health, performance, and capacity information for every node included in the array.

The “Pools” tab lists the top 5 pools in terms of data rate, disk latency, and L2 cache hit rate. And it provides detailed health, performance, and capacity information for every pool included in the array. It even breaks out capacity by hard disk drive vs solid state drive.

From the “IFS” tab, we capture metrics at the OneFS file system level, such as file system throughput, operations rate, and exported directories.

The “Disks” tab lists the top 5 disks in terms of ops rate, queue depth, and latency. And it provides health, performance, and capacity information for every disk in the array. Alternate views can filter the results to only show disks in a specific member node or assigned to a specific pool.

These screenshots represent only a fraction of the information that we collect from your Isilon array. You can analyze even deeper by selecting individual member nodes, Ethernet ports, InfiniBand ports, pools, etc which will take you to more detailed views.

In summary, with the new monitoring support that we’ve included in Foglight for Storage Management 3.1, you’re now able to better monitor and resolve storage-related performance issues quicker when you have EMC Isilon storage arrays in your environment.
