EMC have released an OVF appliance that is meant to allow you to store and browse 30 days worth of VPLEX performance statistics. Version1 is limited to just a few metrics, but it is a very welcome addition to the VPLEX monitoring tools that are available! Requires GeoSynchrony 5.5
Today I was looking up some information on vplex on the EMC support site, my eye was quickly drawn to the following entries:
I have seen no mention of this at all on either Twitter or on the VPLEX community space at EMC: https://community.emc.com/community/products/vplex
This is typical of EMC in my experience, they are terribad at disseminating support information and making new stuff ‘discoverable’.
So what is this thing?
Up till now, you had several ways to monitor, save, and analyze VPLEX statistics.
- The GUI, but that only shows live data, no history, and only shows very few metics and only on high level
- VPLEXCLI: Monitor create, Monitor collect, etc. Powerfull CLI commands, any statistics can be saved. Can create exportable CSV files. But hard to use and understand, and for live monitoring the implementation is truly horrible, scrolling across your screen in a disruptive way, no ‘top’ kind of function here or anything
- EMC VIPR SRM. EMCs statistics and analytics suite. Good for all kinds of EMC products, uses a ‘perpetual’ version of the above mentioned monitor construct. But definitely not a free tool.
- If you have VMware vROPS: EMC Storage Analytics. Adapter for vROPS, but again not free. v3 of this adapter supports vROPS 6.x
- SNMP. Vplex comes with a MIB, but my experience with it so far is that its got some serious compliance (and syntax) issues that are preventing it from working in, for example the vROPS SNMP adapter. (this was my attempt at a ‘cheapo’ EMC Storage Analytics’ 😉
So, nothing we had so far ‘just worked’ as a fast, and -free, gui-based way of seeing some deep statistics. There was something to be said for this not being available in the product itself. It looks like with “EMC VPLEX Performance Monitor” , which is a free OVF download, they are attempting to address this concern.
Lets check the release notes.
VPLEX Performance Monitor is a stand-alone, customer installable tool that allows you to collect virtual volume metrics from a VPLEX Local or VPLEX Metro system. It allows Storage Administrators to see up to 30 days of historical virtual volume performance data to troubleshoot performance issues and analyze performance trends.
The VPLEX Performance Monitor tool is delivered as an OVA (Open Virtualization Format Archive) file that you deploy as a VMware virtual appliance. The virtual appliance connects to one VPLEX system and collects performance metrics for all virtual volumes that are in storage views. Historical virtual volume metrics are stored in a database within the virtual appliance for 30 days. The virtual appliance has a web application which allows you to view the data in charts that show all 30 days of data at once, or allows you to zoom in on data down to the minute.
The VPLEX Performance Monitor charts the following key virtual volume metrics:
Throughput (total read and write IOPS)
Note: The VPLEX Performance Monitor can connect to one VPLEX Local or Metro system at a time. To monitor additional VPLEX systems, deploy a new instance of the tool for each VPLEX Local or Metro system you want to monitor.
Ok, so admittedly, for a version1, not all that much here, no port statistics or backend storage metrics for example. But in most cases, you are gonna be interested in your virtual volumes most of all anyway, so a good start.
Only 1 VPLEX system at a time? We have 2 Metro-Cluster setups in our environment, which translates to 4 engines in total. Does a ‘system’ equate to an engine? I think so, which means I would need 4 of these appliances. Oh well.
30 days is a nice sweet spot for metric saving as far as I am concerned. This appliance is using an embedded database, so don’t expect options to save your data for years. Get VIPR SRM if you want that.
|IMPORTANT Version 1.0 cannot be upgraded. When the next release is available, you must delete the current VPLEX Monitor virtual appliance and deploy the new one. All performance data and user information will be lost.
Take note of the GeoSynchrony 5.5 requirement. This version only came out recently, so I don’t expect many people to be running this yet.
We don’t in any case, so I can’t provide you with an install demo, yet :p
If you have GeoSynchrony 5.5, go give this a try:
(EMC Support account required)
Update 03:03pm: Was googling for “EMC VPLEX Performance Monitor” to see if anyone else had mentioned it yet, came across this video (with 20 views so far, wow!) that showcases the new tool. https://www.youtube.com/watch?v=HiJgmbLkeTU
The next few weeks I will be in study mode.
Next week a 5 day classroom course for VMware vSphere 4.1: Install, Configure & Manage
The week after that its 3 days VMware vSphere 4: Manage for Performance
Then some exam training and on the 25th the VCP4 exam. I am exited and nervous, as I have not studies for an exam or cert for a long time. But I am also confident as I understand a lot of the material already.
In preparation for this I have been gathering some white papers, been reading up on some things and have also been looking for a good book also. I was in the tram today paging through the Kindle app for the Android, and it struck me that the Amazon sphere would be the right place to consume this kind of stuff. I have the Kindle app on my Ipad, my Phone and on 2 PC’s (I don’t yet own an actual Kindle) and the fact that I can pick up wherever I left off, wherever I am and when I have some time spare, appealed to me.
It’s a relief that I can actually find a good use for all these kindle outputs because I was stuck in the dilemma between the physical and the virtual. I will soon be receiving my first leather bound book from Easton Press, but for a while I felt torn between the superior convenience of ebooks, and the wish to have a proper physical book collection. But I realize now I can split the difference; educational books work a lot better as ebooks. So I can find good an honest use for both the old and new at the same time. This is greatly fulfilling to me somehow. I now even have a reason to get a Kindle.. perhaps.
Still in the tram I bought Scott Lowe’s Mastering VSphere 4, Kindle edition, and directed Amazon to send it to all my devices. By the time I got home, it was already downloaded onto my Ipad.
I used to collect a large amount of the MSPress books, but was saddened when I realized that most of them would become obsolete. Getting the ebook versions of these kinds of books might not necessarily be that much cheaper (mastering VSphere 4 set me back $41), but at least its not a waste of paper!
For a long time I justified buying these books by saying that I would rather read from my hand that from the screen, and this is actually true. But The Ipad and Kindle are convenient enough (and even my Android phone is, to be honest), that I cant justify wasting the trees on this kind of book anymore.
I was also thrilled to discover that some of the old Battletech novels are being re-released as Kindle versions. It was impossible to get your hands on, for example, the Blood of Kerensky trilogy in paperback form, it has been out of print for so long. I read most of the novels until Darkage started, but I never got my hands on some of the oldest titles. I hope they bring them all back! What a rich universe to re-discover!
One of our batch of Lenovo T500 laptops refuses to boot from our Windows Deployment PXE server.
So not easy to get our default company image into it. Hard to explain to Lenovo support what is wrong cause its so very specific. All other network functions are just fine. My colleague ran a trace on the server side, and the Laptop doesn’t even seem to contact it.
If I had to guess I would say its network driver issue and this laptop has a very specific revision of network board .. or something.
It seems I am not the only one running into PXE boot issues with a Lenovo.
Don’t really have that much time to dig deeply into it. I would like to see what the conversation is between our WDS server, the DHCP server and the laptop. Something wierd going on there.
