Monitor Service Performance
This policy is similar to the Monitor Service Level Agreement policy and does monitor the same set of run-time performance conditions for an API, and sends alerts when the performance conditions are violated. However, this policy monitors run-time performance for a specific application.
The table lists the properties that you can specify for this policy:
Parameter
Value
Action Configuration. Specifies the type of action to be configured.
Name
Specifies the name of the metric to be monitored.
You can select one of the available metrics:
*Availability. Indicates whether the API was available to the specified clients in the current interval.
*Average Response Time. Indicates the average time taken by the service to complete all invocations in the current interval.
*Fault Count. Indicates the number of faults returned in the current interval.
*Maximum Response Time. Indicates the maximum time to respond to a request in the current interval.
*Minimum Response Time. Indicates the minimum time to respond to a request in the current interval.
*Success Count. Indicates the number of successful requests in the current interval.
*Total Request Count. Indicates the total number of requests (successful and unsuccessful) in the current interval.
Operator
Specifies the operator applicable to the metric selected.
Select one of the available operator: Greater Than, Less Than, Equals To.
Value
Specifies the alert value for which the monitoring is applied.
Destination
Specifies the destination where the alert is to be logged.
Select the required options:
*API Gateway
*API Portal
*CentraSite
Note: This option is applicable only for the APIs published from CentraSite to API Gateway.
*Digital Events
*Elasticsearch
*Email (you can add multiple email addresses by clicking ).
Note: If an email alias is available, you can type the email alias in the Email Address field with the following syntax, ${emailaliasname}. For example, if test is the email alias, then type ${test}.
*JDBC
*Local Log: You can select the severity of the messages to be logged (logging level) from the Log Level drop-down list. The available log levels are ERROR, INFO, and WARN.
*Set the Integration Server Administrator's logging level for API Gateway to match the logging levels specified for the run-time actions (go to Settings > Logging > Server Logger). For example, if a Log Invocation action is set to the logging level of Error, you must also set Integration Server Administrator's logging level for API Gateway to Error. If the action's logging level is set to a low level (Warning-level or Information level), but Integration Server Administrator's logging level for API Gateway is set to a higher level (Error-level), then only the higher-level messages are written to the log file.
*Entries posted to the local log are identified by a product code of YAI and suffixed with the initial alphabet of the logging level selected. For example, for an error level, the entry appears as [YAI.0900.0002E].
*SNMP
Alert Interval
Specifies the time period in which to monitor performance before sending an alert if a condition is violated.
Unit
Specifies the unit for the time interval in minutes, hours, days, or weeks for the alert interval.
Alert Frequency
Specifies how frequently to issue alerts for the counter-based metrics (Total Request Count, Success Count, Fault Count).
Select one of the options:
*Only Once. Triggers an alert only the first time one of the specified conditions is violated.
*Every Time. Triggers an alert every time one of the specified conditions is violated.
Alert Message
Specifies the text to be included in the alert.
