VM Disk IOPS running on XenServer

DustinB3403

So I just wanted to come back and see the performance markers of a few of my systems after having a few days of logging with Zabbix.

This is pretty cool.

822.29 IOPS for a max. Obviously this is a high amount when the average is only 4.15 IOPS.

So now it's time to investigate.

Now checking on the memory usage, it's completely nominal. The VM has 6GB total allocated to it, and has hardly ever gone above 4GB usage. (When this system was on Hyper-V 16GB of memory were allocated to it)

CPU usage is varied, and all over the place, which being a reporting server is expected. I should create a graph that shows me percentage used so I can better correlate the usage to times.

Is this monitoring a Windows or Linux VM?

DustinB3403

At the moment Windows VM's, I'll be working to get the Zabbix agent setup to monitor everything. Including my Hypervisors so that I can get a better understanding of how everything is performing.

i'll be looking forward to it I really need to get our Zabbix Server doing more "powerful" stuff instead of just ping to see if some thing is alive lol

It does that so well, though!

You can have it email or text you when something major breaks.

We have it E-mailing already when a link goes down did play with a text service but thought no! lol Just need really to spend some time with it and get it doing more.,

Probably measuring the cache and buffer too, nearly all tools get this wrong. Use SAR or free -m on that box to see what this is measuring.

@scottalanmiller This is on a windows system, so those wouldn't work.

Really? Skim conversations ~~much~~ always?

Here is the per Core Utilization (I have to thank @dafyre for figuring this one out) 8 cores total, only taking pictures of a few of them.

What this Discovery rule does it it checks the system for the number of cores it has, and then provides the individual core utilization percentage.

Applied to all Windows systems as it's a part of the Windows Template.

Pretty cool right?
