eG MultiThread Pools Test

This test monitors the usage and performance of thread pools, tracking metrics such as pool size, active threads, queue size, and utilization. This helps administrators identify bottlenecks, prevent resource overloading, and ensure smooth system performance.

Target of the test : The eG Manager

Agent deploying the test : An internal/remote agent

Outputs of the test : One set of results for the eG manager being monitored

Configurable parameters for the test
Parameter	Description
Test period	How often should the test be executed .
Host	The host for which the test is to be configured.
Port	The port number at which the specified host listens.
JMX Remote Port	Here, specify the port at which the JMX listens for requests from remote hosts. In the <EG_MANAGER_INSTALL_DIR>\manager directory (on Windows; on Unix, this will be the /opt/egurkha/manager directory) of the eG manager, you will find a management.properties file. Set the port defined against the com.sun.management.jmxremote.port parameter of the file as the JMX Remote Port.
User, Password, and Confirm Password	By default, JMX requires no authentication or security. Therefore, the User, Password , and Confirm Password parameters are set to none by default.
JNDIName	The JNDIName is a lookup name for connecting to the JMX connector. By default, this is jmxrmi. If you have registered the JMX connector in the RMI registry using a different lookup name, then you can change this default value to reflect the same.
JMX Provider	This test uses a JMX Provider to access the MBean attributes of the eG manager and collect metrics. Specify the package name of this JMX Provider here. By default, this is set to com.sun.jmx.remote.protocol.
Timeout	Specify the duration (in seconds) for which this test should wait for a response from the eG manager. If there is no response from the eG manager beyond the configured duration, the test will timeout. By default, this is set to 240 seconds.
Detailed Diagnosis	To make diagnosis more efficient and accurate, the eG Enterprise embeds an optional detailed diagnostic capability. With this capability, the eG agents can be configured to run detailed, more elaborate tests as and when specific problems are detected. To enable the detailed diagnosis capability of this test for a particular server, choose the On option. To disable the capability, click on the Off option. The option to selectively enable/disable the detailed diagnosis capability will be available only if the following conditions are fulfilled: The eG manager license should allow the detailed diagnosis capability Both the normal and abnormal frequencies configured for the detailed diagnosis measures should not be 0.

Measurements made by the test
Measurement	Description	Measurement Unit	Interpretation
Queue max capacity	Indicates the maximum number of threads that the queue can hold at any given time.	Number	The value of this measure denotes the upper limit of the queue's storage capacity, beyond which new items may be rejected or delayed. Monitoring this helps ensure that the system is properly sized to handle workload peaks without performance degradation.
Queue current size	Indicates the number of threads that are currently present in the queue.	Number
Queue utilization	Indicates the percentage of the queue’s capacity that is currently in use.	Percent	A high value for this measure indicates that the queue is nearing its limit, which could lead to delays or processing bottlenecks if not addressed immediately.
Core pool size	Indicates the number of core threads in the thread pool that are maintained and kept alive, even if they are idle.	Number
Pool max capacity	Indicates the maximum number of threads that the thread pool can create to handle tasks.	Number
Active threads count	Indicates the number of threads in the pool that are currently active and executing tasks.	Number
Pool utilization	Indicates the percentage of the pool’s capacity that is currently in use.	Percent
