SAP NetWeaver 7.1.x

Supported versions

NeoLoad supports SAP NetWeaver Web Application Server versions 7.1.x and later.

Configuration

Before the SAP NetWeaver monitor can be used, several NetWeaver server jars need to be installed.

Copy the following files from the NetWeaver installation directory to the <neoload>/jmxlib/netweaver71 directory:

• <netweaver>/<instance>/<java server>/j2ee/JSPM/deploy/lib/sap.com~tc~bl~pj_jmx~api.jar
• <netweaver>/<instance>/<java server>/j2ee/JSPM/deploy/lib/sap.com~tc~exception~impl.jar
• <netweaver>/<instance>/<java server>/j2ee/j2eeclient/sap.com~tc~je~clientlib~impl.jar
• <netweaver>/<instance>/<java server>/j2ee/j2eeclient/sap.com~tc~je~leanClient.jar
• <netweaver>/<instance>/<java server>/j2ee/JSPM/deploy/lib/sap.com~tc~logging~java~impl.jar

After copying the files, it is unnecessary to restart NeoLoad. The files are automatically synchronized with the Monitoring Agent once the changes have been made.

Connection settings

Defining a monitor on a SAP NetWeaver server requires the name or IP address of the machine to be monitored, as well as the connection port. The port is the SAP NetWeaver server access point for the P4 protocol. The port number can be retrieved using the SAP Management Console at: Management Console > SAP Systems > <SAP System name> > <SAP Instance name> > Access Points. The access point is named P4.

In addition to these settings, a valid user account must be provided if authentication is enabled (same account as the one used to connect to the SAP NetWeaver Administration Console).

Create an SAP NetWeaver monitor

NeoLoad makes it possible to create a new monitor either using the monitored machine creation wizard, as described in Create and configure a monitored machine or from an existing monitored machine, as described in Create and configure a monitor.

NeoLoad displays a list of the applications deployed on the configured server. It then automatically selects the most appropriate counters for each of the selected applications.

  • UsedMemory. Current value of the memory used.
  • UsedMemoryRate. Ratio of the used memory to the available memory.
  • UsageRate. Ratio between the used memory and the total memory of the process.
• Thread Pool. Thread pool counters. These counters are divided between application threads and system thread.
  • CurrentThreadCount. Current number of threads created by the thread pool.
  • InitialThreadCount. Initial size of the thread pool.
  • ActiveThreadsCount. Number of threads from the thread pool that are executing an executable task pool. It shows how many threads from the thread pool are currently processing custom tasks. This Monitor does not indicate a problem.
    The number of used threads depends on the number of configured threads and the value of the maximum pool size, and whether this size is reached or whether the pool can still be resized. Even if the pool is resized to maximum and the value of ActiveThreadsCount and CurrentThreadCount are the same, this does not indicate a problem. The purpose of the threads pool is to restrict the request load to a point where the engine can still have enough resources to process these parallel requests fast enough.
  • MinThreadCount. Minimum size of the thread pool.
  • MaxThreadCount. Maximum size of the thread pool.
  • WaitingTasksCount. The number of tasks waiting to be executed by a free thread.
    WaitingTasksCount shows the number of custom tasks that are waiting to be processed, which means that at the moment there are no free threads in the thread pool although the thread pool is resized to its maximum size. In this case, the tasks that are waiting to be processed start accumulating in a queue. Even when the load is high, the threads process a custom task for a certain time and take the next task from the queue. When the size of the queue grows, it mean that either the request rate is growing and the server node cannot handle such a high load, or there is a blocking situation in the server and the threads are not released from the tasks they are currently executing.
    The Monitor is important to detect how effectively the threading system executes the tasks. With 100% usage rate, caller threads are blocked until some of the tasks that are currently executing finish. This could be a symptom of a deadlock or a bottleneck.
  • WaitingTasksUsageRate. The ratio of the current size of the waiting tasks queue to the maximum configured size. WaitingTasksUsageRate shows the percentage of the waiting tasks queue that is currently used.
    The ratio shows how effectively the threading system executes the tasks. When the usage is 100%, the caller threads are blocked until any of the currently executing tasks finishes. This can be a symptom for a deadlock or bottleneck.
  • WaitingTasksQueueOverflow. The number of threads waiting to deposit a task in the waiting tasks queue when the queue is full.
    WaitingTasksQueueOverflow shows the number of blocked threads waiting to submit a task in the queue of waiting tasks. In this situation there are no free threads to process requests and also the size of the queue of waiting tasks is full, so the threads that need to submit a new task in this queue are blocked until a free slot is available. This Monitor shows a problem.
    This counter is unlikely to change its value from 0 because it means that the capacity of the requests queue is exhausted. This is a severe performance problem. This can also be a symptom for a locking situation (blocking back-end calls or Java level deadlock).
  • MaxWaitingTasksQueueSize. Capacity of the waiting tasks queue, where tasks waiting for execution are stored.
  • ThreadPoolCapacityRate. The ratio of the current thread pool size to the maximum pool size in percentages. ThreadPoolCapacityRate shows the percentage of the maximum pool size that the thread pool has currently reached. This is an informative Monitor that does not indicate a problem.
    If the percentage is high, it means that soon the ability to resize the pool will be exhausted. If the ThreadPoolUsageRate is also high, a requests queue will be formed.
  • ThreadPoolUsageRate. Ratio of active threads count to maximum pool size. The outcome is presented as a percentage.
  • UsageRate. Ratio between active threads count to maximum pool size in percent.
  • Configuration. Configuration of the Threads pool.
• JVM. Information concerning the Java Virtual Machine.
  • Version. Version of the Java Virtual Machine.
• Description. Information concerning the SAP NetWeaver server.
  • Version. Version of the SAP NetWeaver server.
