Configuring Alerts

Use the Alert Configuration page to configure alerts for your monitored systems. You must ensure to provide values for all mandatory fields to generate alerts.

Access the Alert Configuration by selecting PeopleTools, and then Health Center, and then Configure Health Center Alerts.

This example illustrates the fields and controls on the Alert Configuration page. You can find definitions for the fields and controls later on this page.

Field or Control	Description
Monitoring Interval	Specify the time interval (in seconds) for monitoring. For example, if you enter 1000, domains are monitored every 1000 seconds. Health Center does not impose a limit on maximum monitoring interval that you can specify, however the minimum interval should be greater than the polling frequency set in the Logstash pipeline configuration file located at (<LOGSTASH_HOME>/pt/config/LogstashPipeline.CONF). For example, if the polling frequency is set to 100 seconds, monitoring interval can be set to 1000 seconds. When you set the monitoring interval, you should consider the number of systems being monitored and the number of alerts that are configured. The monitoring interval varies depending on these factors. It is not advisable to set a low value for monitoring interval in an environment where you have configured many alerts. As a general practice, it is advisable to set the monitoring interval to a higher value in a production environment.
Database Name	Choose a database that you want to monitor.
Name of the Metric	Choose a metric that you want to configure an alert for.
Comparison Operator	Choose either greater than or less than as a comparison operator.
Threshold Value	Specify a threshold value for the metric. If the system crosses the specified threshold value, an alert notification is generated. See Setting Up Health Center Metrics
Threshold Frequency	Specify a limit on the number of times the threshold value can be exceeded. If the system exceeds the specified limit, an alert notification is generated. A combination of monitoring interval value, threshold value, and threshold frequency value generates alerts. The threshold frequency value is associated with the Logstash fetch of metrics. Logstash fetches metrics for every polling frequency that is specified in the Logstash pipeline configuration file. For example, let’s specify that the total physical memory is less than 1000 MB for a threshold frequency of 10 and the monitoring interval is 1000 seconds. In this scenario, an alert is generated when the total physical memory goes below 1000 MB for 10 fetches of Logstash within 1000 seconds (monitoring interval).
Frequency to Notify	Specifies how often the alert notification is to be sent to the monitoring PIA. Valid options are: Single - An alert notification is generated only once for a configured metric, the first time the monitored system crosses the configured values. It will not be generated again unless the Logstash instance is restarted. Repeated - For every monitoring interval, an alert notification is sent if the monitored system crosses the configured values. For example, if the monitoring interval is set to 1000 seconds, alerts are generated every 1000 seconds if the configured values are exceeded.
No of Domains	Displays the number of domains for which alert configuration is set.
	Click the chevron icon to display the Domain Details page where you can choose the domains that you want the alerts to be configured. The number of selected domains appears under the No of Domains column. Note: The Domain Details page does not display if the values on the row or the Monitoring Interval field are not entered. On the Domain Details page, the domains are displayed if you’ve configured Performance Monitor and PeopleSoft Health Center correctly.
