Viewing Statistics for Subscribers on a Cluster

Monitor the performance of subscribers on an ESP cluster by viewing statistics such as CPU history and number of rows received. SCC also uses subscribers to gather information used for monitoring. These SCC subscribers also display within this view.

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 Subscribers.

Table Name	Subscriber Details
Subscribers	This is the header table containing all subscribers within the ESP cluster that the selected node belongs to. Node - name of the ESP node on which the workspace is running. Workspace - name of the workspace to which the subscriber is connected. Project - name of the project to which the subscriber is connected. IP Address - IP address of the subscriber. Port - port number on the subscriber's machine used to receive published data from Event Stream Processor. Stream Name - name of the data stream to which the subscriber is subscribed. Queue Depth - number of rows waiting to be received by the subscriber. Rows in Store - number of rows in the subscriber's data store.

Subscribers

This is the header table containing all subscribers within the ESP cluster that the selected node belongs to.

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

Workspace - name of the workspace to which the subscriber is connected.

Project - name of the project to which the subscriber is connected.

IP Address - IP address of the subscriber.

Port - port number on the subscriber's machine used to receive published data from Event Stream Processor.

Stream Name - name of the data stream to which the subscriber is subscribed.

Queue Depth - number of rows waiting to be received by the subscriber.

Rows in Store - number of rows in the subscriber's data store.

These statistics display for the subscriber you select from the header table:

Statistics	Description
CPU History	Line graph displaying the percentage of total CPU usage over time. 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 - Subscribers view.
Rows Transferred History	Line graph displaying rows received per second. The data on the graph starts displaying from the time you open the Cluster Monitor - Subscribers view.
