Manage disk Utilization over time

[eddymicro]

Hello Alex,

I have tests that monitor Disk Utilization using Performance Counters, currently I have warning and failure, for failure I use: Alert > 95% for warning I use:

("%LastReply%" < "%AlertThresholdValue%") and ("%LastReply%" > "75.00")

I test ever 5 minutes

But what I really want is Bad status ONLY if this happens for 4 consecutive tests and warning ONLY if 4 consecutive tests are between 75 and AlertThresholdValue. I know this is probably easy but I could not figure it out. Can you give me a suggestion?

So, you want to see Ok (or Normal) status when result is over 95% for 1st, 2nd or 3rd time? Then If all 4 results were over 95%, you want to set Bad status? If all 4 results were over 95% but some of them were between 75 and 95%, you want to set Warning status?
Sorry, I don't think its possible to do with HostMonitor.

Alex,

Thanks for the reply. Yes you are correct that is my ideal configuration. Can you think of anything that would do part of this? I don't really need the warning status if I can have some way of waiting for more than one result.

You system have become so successful for us that now the only failures we can't control are disk and cpu utilization as they often peak at 100%, let's say during a backup job or a SQL process. So it's not really a failure until it hangs for 30-60 minutes or more.

I just had a thought, what if the first test never fails, but only goes to warning level. Then a second test fails when it counts a certain number from the first test. Can we do that somehow?

What about example #4 from the manual?
===============
Example #4: you may configure HostMonitor to use Normal status for 1st and 2nd failed probes, use Warning status for 3rd and 4th failed probes and set Bad status starting from 5th failed check:
- enable "Use Warning status" option and provide (%FailureIteration% > 2) and (%FailureIteration% < 5) expression
- enable "Use Normal status" option and use expression like (%FailureIteration% > 0) and (%FailureIteration% < 3)
===============

Alex,

I understand how to set the normal and warning statuses as you suggest. I do not see how to set the bad status. The performance counter test I am using does not allow for an expression. I have failure set to (disk utilization) > 95.

Where would I set
set Bad status starting from 5th failed check.
Or what other way could I set the bad status?

Bad status is set by HostMonitor automatically.
You may use additional expressions when you want to set Normal or Warning status (when status is Normal then its not Bad, right?)

You may just setup test using expressions from my previous post and you will see how it works.
Or better check the manual or visit our web site at
