Viewing Overview Statistics and Alerts for a Node

View alerts for and monitor the performance of the selected ESP node by viewing overview statistics such as CPU, memory, and thread usage.

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 Node.

In the left pane of the ESP Node Monitor view, select Overview.

Name	Statistics
Server	Node name - name of the ESP node. Host - host that server is currently running on. Node version - version of the ESP node. Platform - platform of the machine that the node is running on. Node type - whether node is a manager or controller. State - valid values are running or unknown.
Alerts	This is the header table containing all alerts that have fired for the selected ESP node after you open the ESP Node Monitor view. If you log off without closing this view, alerts that have fired since you logged back on display. Time - when the alert is triggered. Alert Name - name of the alert. This is based on the KPI. Resource - the resource for which the alert is triggered. Severity - alert severity rating. Possible severity ratings are Normal, Warning, or Critical, and are based on ranges of values you specified when setting the alert threshold. Value - the KPI value. The alert is triggered when the KPI value falls within the range of values you specified when setting the alert threshold. Threshold - the range of values you assigned to alert severity ratings. For example, if the low value for the Normal rating is 0 and the high value 100, the threshold is the range of 0 to 100.

Alerts

This is the header table containing all alerts that have fired for the selected ESP node after you open the ESP Node Monitor view. If you log off without closing this view, alerts that have fired since you logged back on display.

Time - when the alert is triggered.

Alert Name - name of the alert. This is based on the KPI.

Resource - the resource for which the alert is triggered.

Severity - alert severity rating. Possible severity ratings are Normal, Warning, or Critical, and are based on ranges of values you specified when setting the alert threshold.

Value - the KPI value. The alert is triggered when the KPI value falls within the range of values you specified when setting the alert threshold.

Threshold - the range of values you assigned to alert severity ratings. For example, if the low value for the Normal rating is 0 and the high value 100, the threshold is the range of 0 to 100.

Statistics	Description
CPU History	Line graph displaying the percentage of total CPU usage over time. The data on the graph starts displaying from the time you open the ESP Node Monitor view. If you log off without closing this view, statistics from the time that you logged back on display.
Memory Usage History	Line graph displaying total memory usage over time, in kilobytes (KB). The data on the graph starts displaying from the time you open the ESP Node Monitor view. If you log off without closing this view, statistics from the time that you logged back on display.
Thread Usage History	Line graph displaying number of threads used over time. The data on the graph starts displaying from the time you open the ESP Node Monitor view. If you log off without closing this view, statistics from the time that you logged back on display.
