wmi / eventlog monitoring quirks

rbartels · Post by **rbartels** » Fri Feb 24, 2006 2:37 pm

I've run into a few issues and would like some clarification.

It seems that when I setup a WMI test or a eventlog test on a remote agent that I have to explicitly tell the remote agent to test itself. If I keep it at localhost it seems to want to check the local counters on hostmonitor and not the local counters of the remote hostmonitor agent that im configuring.

Is there any advantage to having the remote agents do wmi/perf tests or just let them all start from hostmonitor? I mean doesn't hostmonitor tell the agents to do the test anyway? It's not like the remote agents are automagically doing the tests and just sending the results back to hostmonitor as its scheduled. Any advise on the best practices way to implement lots of wmi performance monitoring / event log monitoring would be great. A more indepth knowledge of how hostmonitor is orchestrating test queing or tests per/second might better explain it.

Also I cannot seem to add a wmi/event log tests from the RCC client. I get Error cannot read data: Connection was forcibly closed by the remote host when "checking current data" Any cluepons?

thx

If you want to monitor remote systems, sure there are some advantages
Described right here: http://www.ks-soft.net/hostmon.eng/rma-win/index.htm

I mean doesn't hostmonitor tell the agents to do the test anyway?

"Test by" parameter of the test items defines what application should perform the test.
http://www.ks-soft.net/hostmon.eng/mfra ... htm#Dialog

It's not like the remote agents are automagically doing the tests and just sending the results back to hostmonitor as its scheduled

Sometimes manual can be useful.
Quote from the manual: "RMA is small application that accepts requests from HostMonitor, performs test (or action) and provides information about test result back to HostMonitor".

Also I cannot seem to add a wmi/event log tests from the RCC client. I get Error cannot read data: Connection was forcibly closed by the remote host when "checking current data" Any cluepons?

"checking current data"? Not sure I understand. Where do you see this message?

Right.. Test by ->Remote Agent
Test method -> Perf Counter

THEN you want to select which perf counter test... which opens a new dialog box saying ->
Select a counter to test. THIS dialog box has an option for localhost which IF selected doesn't seem to test the remote RMA which IS "localhost" to that test! You must explicitly tell it to test itself (hope that clarifies that)

As for the RCC test.... Once you as far as above and you select your perf counter test and you wan to check the current current value with the "Get Current Value" button. That action fails with the "Error cannot read data: Connection was forcibly closed by the remote host "

Yes, HostMonitor shows dialog for local system, it cannot use agent to retrieve list of counters

However, if you specify the counter, counter value will be retrieved by specified agent.

As for the RCC test.... Once you as far as above and you select your perf counter test and you wan to check the current current value with the "Get Current Value" button. That action fails with the "Error cannot read data: Connection was forcibly closed by the remote host "

Most likely you have not specified address of the system (where RCC is running) in "Accept connections from the following addresses" list (agent settings)

IC

I thought the RCC interfaced directly with hostmonitors web agent. Then hostmonitor would facilitate adding the test. Your saying that when I use the RCC that I also need to Add that host to every RMA agent that I might want to modify remotely with the RCC?? I thought controlling perms through the operators perm list would be sufficient.

Basically the operation of the telnet service, hostmonitor service and the rcc are different? Telnet service and hostmonitor www based changes are made FROM hostmonitor in the eyes of the RMA agents but changes made by the RCC are seen as comming directly from the client running the RCC (Ok im confused !)

What is web agent?

Not exactly. RCC connects directly to RMA only if you click buttons like "get current value". RCC does not connects to the agent when you want to create/modify test items...

You think agent knows anything about test list and test settings? It does not. RMA responds to requests and provides information about target system, that's it.
