Performance counter not working

[fzavalloni]

Hi,

I am trying to set the Influx Capacitor to work with Exchange Server 2013 (Windows Server 2012 R2). However I got an issue with performance counter (MSExchange Database ==> Instances and Counter name = I/O Database Reads (Attached) Average Latency). When I start the service, it shows the errors below. 1- Engine MSExchange Database ==> Instances: Object reference not set to an instance of an object. 2- Unable to get performance counter MSExchange Database ==> Instances.I/O Database Reads (Attached) Average Latency.. Category does not exist.

I tried to use the escape characters ( >) but did not work.

All others performance counters worked well, only this one is not working.

Do you have any work around for this?

Tks

I did the same test in another environment with Exchange Server 2010 and Windows Server 2008 R2 and the issue did not occurred.

Hello, It´s me again. I think this error is something related to .NET or Operation System. I wrote a simple code that just list the categorys avaiable.

try
            {
                                PerformanceCounterCategory[] categories = PerformanceCounterCategory.GetCategories();
                List<string> msExchangeCategories = new List<string>();

                foreach (PerformanceCounterCategory obj in categories)
                {
                    if(obj.CategoryName.Contains("Instances"))
                    {
                        msExchangeCategories.Add(obj.CategoryName);

                    }

                }
                foreach (string obj in msExchangeCategories)
                {
                    Console.WriteLine(obj);
                }
            }
            catch (Exception err)
            {
                Console.WriteLine("Error: " + err.Message);
            }

```When I run this program in Windows Server 2008 R2 + Exchange Server 2010, it brings 2 categories.
1- Database ==> Instances
2- MSExchange Database ==> Instances
And running in Windows 2012 R2 + Exchange Server 2013, it brings only one category.
1- Database ==> Instances

Probably there is no workaround for it. If you have something, pls let me know.

It sounds like this is not easily fixed. Could it have something to do with 32 vs 64 bit versions?

Hello,

I made it work. I got the same code I posted here before in Visual Studio and compiled it in .NET 3.5 and after that started working. I switched back to .NET 4.5 and compiled again and it worked again. My second test was doing the same steps but with your project Tharga.Influx-Capacitor.Service. I copied the new .exe file to a production server and those errors gone.

I have to admit that I do not know what cause this, but I found a workaround for this.

Have you ever seen it before?

[poxet]

I have not seen this before... So, now you are running a version of Influx-Capacitor that you compiled your self and it works? That soulds great in that case. The question that appears then is; if you where to run the version compiled by the build server and posted at http://influx-capacitor.com/

Do you think we can consider this bug fixed?

[fzavalloni]

Yes. Of course, probably it was a compilation issue of my side.
