Performance Counter Error

[Harroguk]

Hi,

I have a test set up to monitor the available memory via performance counters.

The test is \\x.x.x.x\Memory\Available MBytes. When configuring the test I am able to click "Get current value" and I get the correct reply in the alert value Text Box.

However when I accept the test it will not update, the only response I get is "Error: Unable to connect to specified machine"

I have a similar test working correctly on other servers however am having real problems getting this one to work.

Any help you can give would be much appreciated.

Test Code listed below

Could you provide more information, please?
- What version of HostMonitor do you use?
- What Windows do you use? Service Pack?
- Is HostMonitor started as a service or as an application?
- Are you trying to setup the test using RCC or HostMonitor itself?

Please note: Performance counter test requires admins privileges. Does the service account, that you have specified into "Connect as" box, have necessary rights?

If you are trying to setup the test using RCC, please ensure:
1. RPC service is started on target machine
2. Remote Registry service is starged on target machine
3. There are no firewalls between target system, and the system, where HostMonitor is running.

In fact, you may install Remote Monitoring Agent (RMA) on the target system: http://www.ks-soft.net/hostmon.eng/rma-win/index.htm

Also, Microsoft implementation of Performance Counters is not reliable. We recommend to use WMI instead, it works much better. For instance, to check available memory, you may use "WMI" test method with the following query: Select FreePhysicalMemory from Win32_OperatingSystem

Could you provide more information, please?
- What version of HostMonitor do you use?

6.80

- What Windows do you use? Service Pack?

RCC is running on Windows XP
Hostmonitor is running on Server 2003 Standard SP1
Machine to be tested is Server 2003 Standard SP1

- Is HostMonitor started as a service or as an application?

As a service.

- Are you trying to setup the test using RCC or HostMonitor itself?

I have set up teh test via the RCC

Please note: Performance counter test requires admins privileges. Does the service account, that you have specified into "Connect as" box, have necessary rights?

I can log onto teh server that Hostmonitor is installed to with the [ServiceAccount], if I do this I am able to successfully remotely view the counters of the Server to be tested via Perfmon.

If you are trying to setup the test using RCC, please ensure:
1. RPC service is started on target machine
2. Remote Registry service is starged on target machine
3. There are no firewalls between target system, and the system, where HostMonitor is running.

There is a firewall between the Hostmonitor server and the Server to be tested however other tests to that server are working correctly. These include free drive space tests, 3 Event Log tests, a CPU usage test and a ping response test.

In fact, you may install Remote Monitoring Agent (RMA) on the target system: http://www.ks-soft.net/hostmon.eng/rma-win/index.htm

This is not really an option for us as the Server in question is a Domain Controller

So, the test works on XP (RCC), but does not work on Server 2003 (HostMonitor). Hm. Strange. I think, you should assign "Logon as service" privilege to the account, you have specified in "Options" > "Service tab" (account, that is used to start HostMonitor's service).

Do not forget restart the service, please. Could you restart the server, where HostMonitor is running? It might help.

Seems that when the account under "Options > Service" is added to the groups "Performance Logs" and "Performance Counters" in the AD it works correctly, even though I was specifying a different account (That had those permissions already) under the individual tests.

Thanks for the help it all seems to be working now.

Thank you for the feedback. Really useful information.
