With the launch of Foglight for Storage Management 3.0, we have added support for EqualLogic storage arrays. In this BLOG, I’ll present some screenshots that illustrate the information that we’re able to collect from the EqualLogic arrays.
Foglight for Storage Management uses industry-standard Simple Network Management Protocol (SNMP) to collect information about the EqualLogic array groups. A separate collection agent is automatically assigned to each array group. The agent uses the array group’s SNMP community name to collect and organize information about the groups. If you have not configured SNMP community names for your array groups, you can do so by using the EqualLogic Group Manager.
From the “Summary” tab, we can quickly ascertain the health of each of the subcomponents that make up this EqualLogic array by reviewing the “Related Inventory” section. It tells us how many of each subcomponent are present and and the highest level alarm (warning, critical, or failure) that has triggered for each. We also get a summarized view of pool capacity and LUN/disk health.
From the “Network” tab, we can easily summarize network load and packet error rates across all outwardly facing Ethernet ports. And we get detailed performance and health statistics for every network port in the array.
The “Pools – Members” tab provides performance and capacity information for each of the pools created on the EqualLogic array, including tracking overcommitment and available usable capacity for thinly provisioned pools. It also provides performance and capacity information for each of the individual members (an EqualLogic term) installed in the environment.
On the “LUNs” tab, we can quickly identify which LUNs are the most active and/or exhibiting the worst performance. We also get detailed performance, capacity, and health information for every LUN in the array.
From the “Disks” tab, we see which disks are most active and experiencing the worst performance. We also get detailed performance, capacity, and health information for every disk in the array.
Foglight for Storage Management can map your entire storage topology from VM-to-disk spindle. And, with our one-click storage troubleshooting feature (which I described in a previous BLOG), you can quickly identify bottlenecks in your EqualLogic storage arrays that are causing slow VM performance.
In summary, with the new monitoring support that we’ve included in Foglight for Storage Management 3.0, you’re now able to better monitor and resolve storage-related performance issues quicker when you have EqualLogic storage arrays in your environment.
