Intermittent RMA Errors

[TheDude]

Hoping you can help a few common intermittent errors we are seeing as we roll out Host Monitor across multiple datacenters.

HostMonitor v. 9.58
RMA (passive) v. 4.58.0.297
Windows Server 2008 R2 Standard Service Pack 1

First Error
Test Method: check NT Event Log
RMA: 301 - System Error. Code: 87

Second Error
Test Method: check NT Event Log
RMA: 301 - Cannot open event log. The RPC server is unavailable.

Third Error
Test Method: Perf Counter test
RMA: Cannot read data

Again with all of these they work and function as normal but occasionally/frequently throw these errors.

Increase timeout for this agent.

I don't think we can do anything in this case.
That's network or target server problem. May be server too busy to respond, out of resources...

If some tests works unstable, setup alert profile to start actions after 2nd, 3rd consecutive failure. Also you may use "Repeat test" action after first "unknown" status.

RMA: 301 - System Error. Code: 87

Are you using Windows Vista mode for this test? or Windows NT mode?

Are you using Windows Vista mode for this test? or Windows NT mode?

We are using Windows Vista mode since they are 2008 R2 servers and they occasionally throw the RMA: 301 - System Error. Code: 87

For some reason in one data center only, when we use Windows Vista mode we get 'RMA: 301 - Cannot open event log. The RPC server is unavailable' always without exception. As soon as we modify them to use Windows NT Mode they immediately work.

Target servers are fine on resources (CPU, RAM, Disk).

Thanks for your responses!

How many NT Event Log tests performed by agent?
There are some bugs in new Windows API (Windows Vista API does not work well in multi-thread environment).
Could you add VistaEvLogMode=1 line into [Misc] section of rma.ini file and restart RMA to apply changes?
(note: test probes will require more time)

Sorry, we cannot explain this.
Windows 2008 R2 as well?

What is "VistaEvLogMode"? Are you controlling the number of threads with this parameter?

Yes, all Win 2008 R2

Also, do you have documentation on all ini settings as well as documentation on all error codes?

We will try the settings you recommend and let you know our results. We currently have many of the perfmon tests disabled to see if it impacts the number of errors we are receiving across all other tests.

What is "VistaEvLogMode"? Are you controlling the number of threads with this parameter?

There are 3 possible values for VistaEvLogMode:
VistaEvLogMode=0 normal multithread mode.
VistaEvLogMode=1 HostMonitor/RMA performs one test per server
VistaEvLogMode=2 HostMonitor/RMA performs one test only (one by one)

Also, do you have documentation on all ini settings

No. All standard ini settings should be changed using HostMontor/RMA GUI. Other undocumented settings should not be used, unless there are some real problem in particular environment.

as well as documentation on all error codes?

HostMonitor just displays errors, returned by Windows API. You may check MS KB atricles for specific errors.
