Performance tuning recommendations for the Presentation Server
This section contains information to help you tune your TrueSight Presentation Server environment.
The information is at the server level. If your deployment use case involves more than one server, this information applies separately to each server.
The following tables provides tuning guidelines for a TrueSight Presentation Server that performs both data collection and event management.
Presentation Server tuning parameters
|TrueSight Process name|
Environment recommended value
|Core process||vm.args.system.2||<TSHOME>\conf\custom\csr.conf||TrueSight core Java process||12 GB (Xmx12g)||26 GB (Xmx26g)*|
(Ensure that you set the same value for the Xms and Xmx settings)
|vm.args.system.2||<TSHOME>\conf\custom\idxsrv.conf||Index server process for Elasticsearch||6 GB (Xms6g)||6 GB (Xms6g)|
|vm.args.system.3||<TSHOME>\conf\custom\idxsrv.conf||Index server process for Elasticsearch||6 GB (Xmx6g)||6 GB (Xmx6g)|
|*Based on the latest performance testing, it is now recommended to use 26 GB instead of the previously recommended 20 GB.|
Optimize the event synchronization
If you are on a large environment and if you encounter slightly slower response times due to the large number of events being synchronized, perform the following steps:
- From a command prompt, go to the <installation directory>\truesightpserver\bin directory.
- Run the following commands to set the eventSchedulePeriod property:
tssh properties set eventSchedulePeriod 12000
tssh server stop
tssh server start
The Presentation Server service is restarted to apply the new setting.
On Linux computers, add
& at the end of the
tssh server start and
tssh server stop commands so that the process runs in the background and you can continue to use the shell.
Disable on-access virus scanners
If your environment has an on-access virus scanner enabled, the startup and access time of the TrueSight Presentation Server might increase.
Exclude the TrueSight Presentation Server installation directory from the on-access virus scanner. Consult the product's documentation for additional information.
Optimize a large deployment
In a large deployment, optimize the following parameters to enhance the UI login and response time.
Edit the installedDirectory\conf\custom\csr.conf file.
In the System properties section, increase the
vm.args.system.2=-Xmxsetting by 20%.
For example, if the current setting is
vm.args.system.2=-Xmx15g, update it to
Ensure that your system has sufficient RAM to accommodate this increase in value.
Update the GC related properties section with the following changes:
vm.args.system.32=-XX:ParallelGCThreads=8 vm.args.system.33=-XX:ConcGCThreads=2 vm.args.system.34=-XX:InitiatingHeapOccupancyPercent=55
- Under the GC related properties section, add a new property
vm.args.system.35=-Xmsand set it to half of the
For example, if the updated setting is
