I have a number of Windows Services written in .NET/C# and each of these have custom performance counters added via the System.Diagnostics.CounterCreationData and System.Diagnostics.CounterCreationDataCollection classes.
In System Center 2012 I have a Dashboard for each of these Services in which I want to display/graph the values from my custom counters. However, I only see the standard performance counters which are the same for all Services and can not find my custom counters anywhere. My counters are visible via PerfMon but SCOM does not see them.
Is it possible to do what I want, and how?
Thanks
Have you tried starting the console via command prompt?
Use /clearcache when calling the exe to allow the perf data to reload.
try using powershell script to collect your counters and submit the collected data in a property bag. it should work.

I am working on a tool to generate fake data for System Center Operations Manager for internal testing purposes. I wrote a script as part of a discovery that is able to create an instance of any class I want and make SCOM fake-discover it. Currently, I'm using a class for AD Printer. Now the next step is to somehow create alerts on behalf of the Printer. For this, I wrote a rule targeted at the AD Printer, which reads from the logs to detect when it should be fired. The logs are being written to from a PowerShell script. However, I see no results. But when I target the same rule to All Windows Computers, I see the alerts.
From what I understand the rule will run on all agents that have an instance of the target class. Since I fake-discovered the AD Printer on this agent (which also happens to be the Management Server), should the rule not run on this?
Any other suggestions on how I can achieve this are welcome as well.
PS. I probably cannot share any of my code as I am under an NDA, but I can clarify my approach further, if needed.
Yes, the Powershell script should run on the agents which have instances of the AD Printer. I recommend you to check the OperationsManager event log for script errors. The easiest way to generate (fake) alerts is to set up a simple, Event-based text log monitor: one specific word can trigger the unhealthy state (which in turn generates an alert), while another word resets the monitor to the healthy state. You can specify criteria for both events. Look at this blog post for further details.

I had done all the sensu-uchiwa-graphite set up. And i get a new request,:(. Rather than go to change the threshold in check.json file on sensu server..any plugin at the UCHIWA that this adjustment will be shown in Uchiwa dashboard? I asked because in case that my application teams wanna change it by themselves without accessing to server.
I think sensu-admin in enterprise is available but we need to pay big money per year ;(...
Thanks in advance to help.

This is fairly doable if you use a configuration management system like Chef/Ansible/Puppet - especially if you run standalone checks on the sensu-client.
This allows the clients to define their own thresholds, rather than changing the sensu servers themselves.
See https://sensuapp.org/docs/latest/reference/checks.html#standalone-checks
In this case, the definitions for the checks are sitting on the client servers and they have the choice of their thresholds or configurations. The client itself manages how often to run the check and sends the output back to the server, rather than the server requesting the checks. This helps quite a bit as far as scaling or multitenancy.
The other way to accomplish this, if you are tied to serverside checks, would be to use client attributes (https://sensuapp.org/docs/0.25/reference/checks.html#check-token-substitution)
For example, you can have a cpu check that says something like check-cpu.sh -w :::cpu_warn::: -c :::cpu_critical::: and these come from a cpu_warn and cpu_critical value from the client.json on the client server.
Source: We use sensu extensively in an enterprise environment across thousands of hosts and have been working through these same issues.
I have configured a JON server 3.1.0 and agents allowing to monitor JBoss AS.
I've set alerts to tell us when the process goes down and I now would like to export reports, especially with the availability/unavailability periods of the different processes.
It seems that the predefined reports concern more the utilization of the CPU/memory, but not the availability.
The purpose would be to export this report at the end of every month with the unavailability periods over the past month.
Is this possible? Does this exist by default? If yes, how can I access to this? If not, is there a way to get it?
Thanks for you support
JON 3.1.0 should contain the REST-api as tech preview though (not sure). If this is in, you can use this to access the availability history e.g. via a http
GET localhost:7080/rest/resource/{id}/availability/history
with {id} being the id of the resource you need the report for.
Another option is the CLI, where you can write the output of the cli commands to a file.
Using Fiddler, I want to send multiple requests in one hit, to check the response time from the server, if too many requests are sent at one time. Basically, I want to perform a, kind of, load testing on my service. Is there any way to perform this action? I want to repeat the process of hitting the server, again and again.
In Fiddler, you can repeat a request as many times as you like by hitting SHIFT+R on the selected Web Session. You'll be prompted for a repeat count and then Fiddler will issue the specified number of requests.
Caveat: Having said that, generally speaking, you'd want to use a tool like Telerik Test Studio's Load Test tool for a task like this. Alternatively, you could use Fiddler's Export architecture to generate a script for VS WebTest or Microsoft's free WCAT tool and use those tools to generate the load. You can then run these scripts on multiple machines from multiple networks and generate a more-realistic set of load than you could by simply running on a single client.
I've been load testing with StresStimulus today. Overall, I'm quite impressed.
It's now a standalone application (it used to be a fiddler extension). There's a 7 day free trial which allows up to 50 virtual users. Also, the setup wizard is great for beginners.
For basic load testing the trial should be fine. Consider upgrading for extensive/professional use.
Is there a way under Citrix for my application to make a call to the Citrix host to find out how many copies of my application are presently running? We want to limit this in our license and we need to have a way to verify it in the code.
thanks - dave
No, Citrix XenApp (which is their best-known product and probably the one you are asking about) does not offer any APIs or services that can be used for application license checking.
The closest you could get via Citrix is to use the Powershell SDK and call Get-XASessionProcess to get a process list. The problem with this approach is you need to be a Citrix admin, and it's a fairly round about way of doing this.
If I wanted to implemented a simple concurrent limit for license enforcement I would look at two options:
Implement a simple web-service somewhere that my app talks to, to get a license.
Create a simple Windows service that tracks processes to maintain a count of concurrent instances of your app. When the configured license count is exceeded you could set a flag in a shared memory section in the global namespace. Then in your app you check this flag at startup and exit immediately when it is set.
You could track processes using WMI, e.g.
