I need to use PerfMon to collect data from several machines, and I need to be able to turn collection on/off at certain times. I've got all the data points configured on each machine; I just need to start/stop PerfMon, and to start/stop collection of a set of data points.
For reasons I won't go into, I can't simply configure all collection from a single PerfMon instance on a single machine - I need to start/stop PerfMon data collection on multiple machines at (about) the same time.
The systems involved are all running Windows 2003 Server, and I'm unable to install any additional software on the systems.
Is it possible to do this using e.g. PowerShell (or something else that's normally installed on Windows 2003 servers)?
Take a look at logman.exe. You can use it to create countersets (if you already have a template definition) as well as to start/stop perfmon data collection. See this Overview of Performance Monitor for some information on security requirements of the account executing logman.exe.
From .bat, MSBuild or Nant you can do something like:
Logman start [logname] -s [computername]
or
Logman stop [logname] -s [computername]
Once you've collected all those log files you can use relog.exe to import them into a sql instance so that you can more easily query/report against them.
I know you mentioned you can't install any additional software, but...depending on the setup of your lab, or other environment, you might want to consider having perfmon log to a sql data store. Even if its a Sql Express instance running on a server in the environment it might make your life easier. At least it could/would skip the importing of the data into a single store to make it easy to query/analyze.
Good luck!

I'm installing the latest MMASetup-AMD64.exe and want to hook up to Log Analytics AND SCOM. But, I'm having trouble finding the command line parameters for SCOM. Does anybody know them? The Log Analytics ones are well documented and are here:
ADD_OPINSIGHTS_WORKSPACE=1
OPINSIGHTS_WORKSPACE_ID="1234"
OPINSIGHTS_WORKSPACE_KEY="5678"
I need the equivalent parameters for management group name and management server. Effectively completing these boxes but via the command line.
Thanks in advance.
I believe parameters for management group, secure port, etc. are not available with MMASetup-AMD64.exe. Here are the supported command line options with it. So may be, if its feasible in your environment and setup, try to use MOMAgent.msi to install agent manually or to deploy System Center Operations Manager agents from the command line or by using the Setup Wizard. The parameters like MANAGEMENT_GROUP, SECURE_PORT, etc. are all explained along with examples in this document. For more information, please refer it.

You do know that this represents a value of 10 hours, correct? You are willing to lock resources for that length of time? This is counterintuitive for optimal application performance as you would seek to recover resources as fast as possible to support more sessions versus locking a resource for an extended period of time.
I refer to the following performance "compass rose" as a guiding item (independent of tool)
If you need to amend the file on a remote server you can do this either via OS Process Sampler or via SSH Command Sampler. The first one is a part of JMeter installation, the second one you can install using JMeter Plugins Manager

I have installed OEM 13c and deployed a couple of agents and want to test out the Log File Monitoring utility. I have enabled it and added a log file to monitor.
When I go and test it out, it does not show any alerts when they are put into the Log File. On the agent server, I have tailed the file and see the messages coming into the log file.
Does anyone have experience adding log files to OEM? I could have configured it wrong. Or is there any troubleshooting steps that I can follow to see if the server is even contacting the agent for reading the log file. Status of the agent is good with no incidents.
Without access to the system, it would be difficult to tell you the exact cause of this issue. However, I can list a few potential causes of this issue that I have experienced personally:
Permissions. The Oracle Enterprise Manager Agent is very convoluted when it comes to system permissions within a remote server. The agent can be owned and run as any number of users but during metric evaluation, may also need sudo or pam-authentication permissions to access certain entities on the server. Depending on the authentication profiles on that server, this could be the cause of your issue. There are ways to grant the agent access through the PAM stack if that is necessary.
Syntax. The wildcard syntax in the OEM GUI can be a little confusing as well. I would play with the wildcard elements a bit on the "String" component to ensure that it isn't as simple as adding wildcards to the beginning and end of the string. Without diving into the binaries of the agent plugins, it is difficult to assess exactly how the agent is evaluating this particular metric
One suggestion I would have is to go through the agent commands. There are specific commands you can run to manually force an agent to evaluate a particular metric for a particular target. This can allow you to manually trigger the metric collection locally on the server and evaluate what exactly is being performed at the agent level.
On the system I was running (12c) the command was as follows:
emctl control agent runCollection <hostname>:host host_storage
I am running load tests using the built in system in Visual Studio 2010. The setup is a test controller with four agents. The tests that I am running will put load on an application server and a database server. The problem I am having is that I am unable to get values from the performance counters on the application server and the database server. I have followed the instructions on http://msdn.microsoft.com/en-us/library/ms404661%28v=vs.100%29.aspx and http://blogs.catapultsystems.com/tlingenfelder/archive/2009/06/18/performance-counters-timeouts-and-load-testing-with-visual-studio-2008.aspx in order to troubleshoot, but to no avail.
Using Performance Monitor (perfmon) I can connect and get values from the performance counters on the application server and database, tested from several computers. But when running the load tests, I get nothing.
I am trying to get system performance counters like CPU% and memory usage, so there are no custom counters involved.
Any hints as to what I shoud do next?
The main problem was that I was not aware of that in order to get performance data from a computer during load testing it should have a test agent (or controller) installed on it.
Install test agents and register them with the controller on all machines used for load testing (for me, the appserver and the database, those did not have test agents installed)
In the actual load test in Visual Studio, remove the appserver and database from the counter sets
Add them again
Run the test!
Seems like the old reference to the appserver and database in the load test did not work as expected, hence the need to remove and add them again.
Voila! Performance counters appears and returns values!
I have also the same problem.
The only solution I found is to remove some counters in counter sets and also increase the sampling interval (see here).
Another things that i have in my rig are Roles : agents will run tests but not collect data ; this will be done by my web server (installed a test agent on it). Please look at the link.
I always forget to check what's going on in IIS on our webservers, and am wondering: is there some stupid applet or something that always runs locally that I can click on to check event logs and IIS logs on a remote machine?

You can set up samurize to follow the output of the logging on the local and remote machines but it requires some setup.
You can use a remote shell utility such as OpenSSH to connect to remote machines securely.
One at a time. Compmgmt.msc -> connect to another computer.
But one at a time is boring. Monitoring dozens of machines? I've been using logparser from MS for my log monitoring needs. I run a query that dumps errors and warnings to a csv file a few times a day.
So far, I've only used it to aggregate event logs across the dozen servers in our QA environment, but it appears to take many forms on log input, including IIS. A pseudo log file query (don't have samples with me)
logparser "Select [eventtype], [message] into output.csv FROM \\server1\system, \\server2\system" -i EVT
This shows: You can aggregate multiple servers. You tell it the input format - it supports a dozen log types. You can dump it into a csv file. It looks sort of like SQL. This article in security focus has an IIS log sample.
I'm not an applet type of guy, so I haven't though much about desktop widgets to do this.
