Hostmon is not responding

ron.visser · Post by **ron.visser** » Fri Feb 04, 2011 4:01 am

After a short while the hostmonitor application is not responding anymore.
In the system tray it looks like it's running but I can't show the gui anymore. Also it doesn't send any alarms. If I start RCC or try or start the web interface I get a connection error.
It doesn't make any difference if start it on the desktop or as a service
If I leave the GUI open It looks like that som tests keep the status Checking. With other words it hangs

Tried to install it on another system same result
disabled all the eventviewer tests same result
run the tests by an agent on the system wich have tests with status checking.

Currently I'm using hostmon 8.82 on W2003 SP2 server and using an admin account for all tests
I use the following tests
CPU usage
ODBC
check service
check UNC

In the event viewer I Find sometimes teh following Informational

The description for Event ID ( 1002 ) in Source ( HostMonService ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. You may be able to use the /AUXSOURCE= flag to retrieve this description;

Hope you have any idea
With kind regards

Usually such problems can be caused by firewall or antivirus monitor.

Do you have installed some antivirus monitors, personal firewall, content monitoring software? Non stanard winsock components?
What ODBC driver do you use for ODBC tests ?
Do you use ODBC logging ? What ODBC driver is used for ODBC logging ?

Also have you used HostMonitor Auditing Tool (available thru menu View)? Any warnings?

Our Firewall is disabled. We use AV software but on the server where hostmon is installed, is the on acces scan disabled. It only perform a full system scan weekly.

The ODBC driver, momently I use te Oracle 10.2 driver and I also used a Oracle 11.0.2 driver. I could'nt find any Oracle logging with a relation to the problems.

In the auditing tool are no messages. Does it keep a history?

Currently I'm only checking (by agent) 1 system and it works fine.
I add some test's and see what's gonna happen

Kind regards Ron Visser

What exactly AV do you use ?

No, it shows actual state.

The ODBC driver, momently I use te Oracle 10.2 driver and I also used a Oracle 11.0.2 driver. I could'nt find any Oracle logging with a relation to the problems.

Oracle clients 10 and 11 often lead to problems, while version 9 is most stable. Could you try to downgrade Oracle client to 9 ?

The AV = McAfee 8.7.0.570 (Enterprise server)
Downgrade to Oracle client 9 is not an option. maybe i'll try this on a testsystem.

At te moment it is still running without ODBC tests

Will it help if I use an agent to perform the ODBC test?

Kind regards Ron

and HostMonito works fine?

This may help to localize the problem. You may setup RMA to perform ODBC tests (its pretty easy, you may select set of tests and change "Test by" property for all ODBC tests at once). If HostMonitor will works just fine while RMA will crash, then we will know for sure - problem caused by ODBC test.
Also you may setup additional test that will check resources used by RMA; e.g. you may setup 2 WMI tests using queries like
select HandleCount from Win32_Process where caption='rma.exe'
select ThreadCount from Win32_Process where caption='rma.exe'
