Download Perfmon Server Agent
Mohammed Huberty
During a load test, it is important to know the health of the servers loaded. It is also nice to see if you are targeting a cluster if the load is correctly dispatched. To address this, the plugin package now supports server monitoring! Using it, you can monitor CPU, Memory, Swap, Disks I/O and Networks I/O on almost all platforms!
JMeter cannot retrieve by default server metrics except Tomcat ones. To overcome this situation, we have developed a server agent which will get performance data for JMeter. The agent uses the SIGAR open source library. It is composed of a Java common part and native libraries per OS.
In GUI mode, just add the listener, define servers and metric types to monitor, ensure the agent is running at remote server and is not blocked by a firewall, then run the test. The values will be displayed at real time chart.
PerfMon Server Agent did support only few metrics in versions up to 0.4.2. The old agent still supported in PerfMon Metrics Collector version 0.5.0+. However, version 0.5.0 ships new ServerAgent which provide over 75 separate metrics, support per-process CPU and Memory metrics and even custom metrics for measuring whatever you want: file sizes, database row counts, Java heap sizes and garbage collections.
I am trying to run long SOAK tests (24h) monitoring server CPU/RAM utilization in Jmeter. Using perfmon server agent and plugin. Tests are run headless, using JMeter Docker image. Got everything setup and job is running fine in Jenkins. Measurements are sent to the server every 10 minutes. The tests results are saved in CSV during the test.
However, although the test runs for 24 hours, Perfmon agent seems to be sending data only for around 2 hours. This is how much data i can see is saved in CSV file. Regardless test runs for 5 hours or 24, 2 hours of data is saved.
I am working on JMeter (version 5.2.1) and my requirement is to monitor the server health. Now for that I am using Perfmon plugins (jpgc-perfmon-2.1) and listener to catch the desired output. Also I have downloaded Server Agent (Server Agent-2.2.1 and Server Agent-2.2.3). I am hosting the script and running the server agent on the same machine.Now for capturing the CPU utilization or Memory utilization first I am starting the server Agent and then I am running my JMeter script. But as I am clicking on the start button, the server agent is getting stopped automatically. Also I have tried communication between my local machine and server agent using telnet and its responding properly.

JMeter Plugins has a plugin called PerfMon - which offers a great way to collect metrics on your server health. (Note: be careful not to confuse this with the Windows Performance Monitor - which is also called PerfMon!)
I hope that this information has helped you better understand JMeter performance metrics and how to set up server side performance monitoring for your JMeter testing. Try adding these important metrics to your load test reports and let us know how it goes in the comments!
Note: The server agent will collect metrics and send them to Jmeter by UDP or TCP protocol, where the default port is 4444. To run the server agent on a different port use the following command
Create the CloudWatch agent configuration file with the wizard1. Follow the steps in Create the CloudWatch agent configuration file with the wizard. This is an example of the file that the wizard generates:
2. You can also configure your CloudWatch agent config.json file for other Windows Performance counters. This example shows a generic syntax that you can use to add performance counters that are available in Performance Monitor. Be sure that the counters are visible in Windows Performance Monitor or the agent can't push any datapoint for that counter.
I am also using the performance counter Failed Jobs _Total and I see 3 jobs failed but when I check Activity Monitor I do not see any failed jobs for the past few days...So this _Total is storing every job that failed since the Agent was started or so I am guessing. I only want to see jobs that failed in say the last 24 hours Is there a way this counter can be reset to 0...Restarting the agent doesn't seem to be the best way to reset counters IMHO...
After you apply an update SQL Server 2008 R2 or SQL Server 2012 that is beyond a certain version, the Performance Monitor files sqlagentctr100.dll and sqlctr100.dll in the system32 folder are not updated as expected. For detailed information, see the "More information" section.
The first thing you need to do is launch Performance Monitor. This application can be found under the Administrator Tools in the Windows Control Panel or you can launch it from the Run prompt by typing in "perfmon" and clicking OK. Under the Performance Log and Alerts select Counter Logs and right click to select New Log Settings. The first thing you need to do is give the Counter Log a name.
When you have installed PeopleTools and transferred the appropriatefiles to your web server, application server, and Process Scheduler server,all of the required elements are in place. You do not need to install additionalmodules for the Performance Monitor.
At least two PSAPPSRV server processes must be enabled. This ensuresthat the monitoring system can publish notifications of configuration changesthrough the PeopleSoft Integration Broker gateway. You can enable more PSAPPSRVsto meet increased demand.
If you have more than one PSPPMSRV configured,the monitor servlet automatically implements load balancing across the multiplePSPPMSRVs. Also, if you configure multiple application server domains, eachwith its own PSPPMSRVs, the monitor servlet automatically implements loadbalancing and failover across the domains.
By completing the internet portion of the PeopleSoft Multi-PlatformInstaller program, you have installed all of the elements that PerformanceMonitor requires on the web server. No additional installation proceduresare required.
The PSPPMSRV application server process acts as the PPMI client whenyou record PeopleSoft performance data. To register as a client, the PSPPMSRVrequires the appropriate permissions in PeopleTools Security.
The PSPPMSRV servers periodically read the PPMI value to determine thePPMI URL. When it is set to NONE, the monitoringsystem is disabled, which means that the PSPPMSRVs do not insert performancedata into the monitoring database.
A gateway URL needs to be specified so that the monitoring system cannotify the monitor servlet of configuration changes. The monitoring servletin turn notifies the monitored agents of these changes when they next communicatewith the servlet. This communication uses the gateway, which you specify inthe Integration Broker administration pages.
If the agents have successfully registered, the PPMConsole (a new browserwindow) displays a list of all registered agents along with the agent configurationinformation. If no agents have registered, no list appears.
With years of experience providing performance testing services to business organizations from diverse niche, this blog will help you understand the benefits JMeter dissipates for performance testing while sharing a quick guide on measuring server performance using JMeter.
JMeter consists of many listeners that provide useful information like the response time of each request, the number of requests being processed, response data, throughput, error percentage, etc. but actually there is a strong need to know the utilization of server system resources, like CPU/Memory utilization.
Hi all,i have a problem and i am short of knowledge pls helpthe problem is that we have some WorkStation monitoring agent that report high re-transmitthe agent collecting prefmon every sec and avg every 15 sec and end the percent to the serverthe problem is we dont see correlation with WireSharkin the Perfmon u can see fragment retransmitted and in the Wireshark none or low numbersanyone can understand me who is Lying the Perfmon or Wireshark ??
Depends on where and how the Wireshark capture is taken. While you may capture on the machine where the traffic originates/terminates, it is always the best to capture outside it, using port mirroring or similar techniques to copy the traffic to a machine dedicated for capturing. This allows to avoid issues like TCP offloading which may make some packets invisible to the capturing process and like packets missed due to insufficient processing power. On the other hand, if the perfmon is running on the same machine like the capturing process of Wireshark, both should be affected by the same effects.
The Integration with Windows Performance Monitor feature exposes the performance counters of this software to the Windows Performance Monitor (perfmon) tool which logs and analyzes system performance. The DataCore Performance Monitor Configuration console is used to select the performance counters, create data collector sets, and export them to Windows Performance Monitor. A Windows service named DataCore Perfmon Agent (DcsPerfMonAgent) collects performance data for the configured data collector sets and reports the data to Windows Performance Monitor, where the data can be viewed, logged, and analyzed using the features of Windows Performance Monitor. The Integration with Windows Performance Monitor feature also enables other applications to access the performance data for this software from Windows Performance Monitor in order to monitor the data in third party management applications.
