Status Checking

Post by apaitoperations »

Hello Alex,

We use Views to display only relevant testitems.

In View-Properties there is NO Option to filter for Status "Checking" - so how can i see these Testitems ?

I will check total thread-count again when HM stops working next time

You cannot use Views for this purpose. Only Folders.
If new debuglog1.txt does not show any test items, then skip this.
H'm... if Windows Task Manager will show much less threads, this means HostMonitor "sees" problem that does not exist :roll:

Alex

no - new debuglog doesnt show any such items :-(

I will compare thread-count debuglog <-> Windows-Task-manager next time.

I have to many testitems to display them all -> RCC will stop responding or become so slow if i display all testitems :-(

Hi Alex,

I have in our 2nd HostMonitor installation already recorded the number of threads. Below the values ​​from the debug log and threads during the last freezing:

Debuglog:

[12.11.2012 12:35:04] PerfCounter - Prozess(hostmon)\Threads Ok 23

I note: the values ​​for TTThreads and hostmon\Threads are extremely interdependent.

And now?

Could you please explain what exactly this means? How many threads was used by hostmon.exe process according to Task Manager or Performance Counters (while TTThreads: 1001)?

I loged with 2nd hostmonitor threads was used by 1st hostmon.exe process according to Performance Counters. Is there any difference to task manager? I mean this is the same value. I have compare the values live and the values are identically.

Then I do not understand anything :(
1000 threads, 1000 started tests but just 18 items in checking status for more than 40 sec?

I interpret my debuglog so that the value for TTThreads increases continuously up to 1000 (in duration of 4 days), and then after a short time, the system no longer performs tests. At this time all other values​​ such as threads, handles and cpu usage are normal.

So the question is: Why is the value for TTThreads constantly increasing after restart?

The test frequency is now standard to me all the time at 37 tests / sec.

That's very easy to answer - because some test threads hung.
Hard questions:
1) why it hungs
2) if test threads hung, why you do not see "Unknown"/"Timed Out" and "Checking" test items? Its just impossible!!!!

BTW: is this complete list?
-----------
thread log during and after freezing:
[12.11.2012 11:08:44] PerfCounter - Prozess(hostmon)\Threads Ok 55
[12.11.2012 11:13:49] PerfCounter - Prozess(hostmon)\Threads Ok 41
......
----------
or you just copied 18 items while there are much more in the log?

Alex, you got me completely misunderstood.
1000 threads, 1000 started tests but just 18 items in checking status for more than 40 sec?
The 18 lines are not from debuglog. This is a cutout from another logfile from the other Hostmonitor, that monitors continuously the main host.

Then I don't understand why "TTThreads and hostmon\Threads are extremely interdependent"?

Ok, so there are no hung threads, no "checking" and "timed out" items?
And hostmon.exe process always has < 100 threads (even when monitoring is stopped and TTThreads>1000)?

Then this is completely different issue - there is no real problem while HostMonitor "sees" the problem because of some mistake related to thread counter.
Ok, we will check everything related to this counter and may be provide some quick fix with option that disables this counter check...

Alex

thread counter in Hostmonitor

Post by apaitoperations »

Alex,

So there is an internal check within Hostmonitor to count its threads ?

And it has a limit ?
