Viewing Statistics for Streams on a Cluster

Monitor the performance of streams on an ESP cluster by viewing statistics such as CPU history and number of rows processed.

Prerequisites

Enable the time-granularity option on the node in the Event Stream Processor project configuration (.ccr) file. See the Event Stream Processor Administrators Guide for information on the project configuration file.
Log in using the espMonitorRole role to be able to perform this task.

Task

In the Perspective Resources window, select the node, click the arrow, and select Monitor Cluster.

In the left pane of the ESP Cluster Monitor view, select Streams.

Table Name	Stream Details
Streams	This is the header table containing all streams within the selected ESP cluster. Node - name of the ESP node on which the workspace is running. Workspace - name of workspace on which the stream is running. Project - name of project to which the stream is attached. Stream - name of stream attached to the project running on the node. Queue Depth - the number of rows waiting to be processed. Rows In Store - the current number of records in the stream's store.

Streams

This is the header table containing all streams within the selected ESP cluster.

Node - name of the ESP node on which the workspace is running.

Workspace - name of workspace on which the stream is running.

Project - name of project to which the stream is attached.

Stream - name of stream attached to the project running on the node.

Queue Depth - the number of rows waiting to be processed.

Rows In Store - the current number of records in the stream's store.

These statistics display for the stream you select in the header table:

Statistics	Description
Rows Transferred History	A line graph displaying the number of rows processed per second by the stream over time. The data on the graph starts displaying from the time you open the Cluster Monitor - Streams view.
CPU History	A line graph displaying the total CPU usage over time for the stream. The user CPU usage and system CPU usage are also shown on this line graph. The data on the graph starts displaying from the time you open the Cluster Monitor - Streams view.
