I have an internal lab I need to monitor, but I want to make sure that I'm monitoring the right stuff (this is my first crack at operational management). Right now I have the following servers to monitor:

  • Web Servers (IIS)
  • Database server (SQL - OLTP)
  • Data warehouse server (SQL - OLAP)

Plus 3 servers that actually generate load during load tests.

Currently I'm just monitoring for disk space usage and am getting alerts if any logical disk falls below 10% free space. None of these machines are production, they're all in a testing lab, so 24/7 uptime isn't required and we don't have someone on call to fix the machines. Mainly we just want a way to know if a disk is about to fail, if we're running out of space during the day (due to database bloat during a test or whatever), and anything I'm not really considering (do I need to monitor network traffic, for example?)

For the purposes of this question, assume I'm just running Perfmon and am picking out the counters manually.

Many good questions generate some degree of opinion based on expert experience, but answers to this question will tend to be almost entirely based on opinions, rather than facts, references, or specific expertise.If this question can be reworded to fit the rules in the help center, please edit the question.

PhysicalDisk - Average Queue Length is always a good one to watch, this could indicate a number of things: performance is low, disk failure imminent, need more memory, need more spindles, etc.

That's a good point. Tracking that on physical rather than logical makes a lot of sense for the operational monitoring aspect, thanks! Would there be any sort of industry threshold on this number, or is it dependent on what my baselines are? – Sean Long Sep 3 '13 at 13:05
Yes, it does depend on your baselines, but largely I take action when it is persistently over 2 (or, on slow/old machines, over 5-10) for prolonged periods. See for a bit of Microsoft blurb on the matter. :) – Daniel Dainty Sep 3 '13 at 13:10
