Universal Storage Collector could extract performance data not only from EMC Storage Systems 🙂
New Extractor extracts data from IBM Storwize storage family.
Extracting performance data from EMC VMAX isn’t an easy task starting Unisphere 8.
Unisphere 8 store performance in its own format – UPV. It show collected performance, but can’t read any other UPV file. If you reinstall Unisphere it will not show performance from UPV files collected before reinstallation.
Mitrend (online tool for analysing performance data) doesn’t understand UPV files. Mitrend asks for old STP format. But to collect data in that format you should setup one more server – server without Unisphere.
There is a special tool for reading UPV files – Unisphere Offline Performance Viewer. But this tool available only for EMC SPEED Gurus.
Here is a description how to extract performance data from EMC VMAX.
My VNXCollector could extract performance data from EMC CLARiiON/VNX using naviseccli. But I have added extractor for NAR files.
Here is a description why.
First, I have created a VNX Collector. Then I have created a VPLEX Collector. This systems are very similar. My next task was periodically extracting performance data from NAR files. At that moment I decided to create an universal tool to collect performance data from different storage systems with output to different collectors. Later I decide to add gathering performance data from EMC VMAX.
And now after some month of work I present Universal Storage Collector – a modular and flexible tool.
Graphite is a nice tool to look on performance. But from my point of view this is mostly a ‘high-level’ view. Sometimes we need a detailed report in the document. That’s why I have created one more tool for generating report about EMC VPLEX performance – VPLEX Performance Reporter.
This tool was improved and integrated into the new tool Universal Storage Collector
One more storage system I need to analyze is EMC VPLEX.
We can use VPLEX GUI to see performance data in real-time, but how to see a performance for a long period of time?
VPLEXCollector is a tool to gather performance data from VPLEX and providing it to the Graphite.
It is not easy to get information about Pool LUNs distribution by FAST VP tiers in EMC VNX.
In Unisphere (GUI) we need to click on properties of every single LUN.
In Naviseccli (CLI) we can get report for all LUN but it’s ugly as usual.
So, I have created a simple tool to get nice report about LUN distribution.
Optionally it reports LUN’s user size, consumed size and metadata size.
