The coldfusion monitor is a wonderful feature which you should use for the better performance of your application. Today we will focus on those features of the coldfusion server monitor, in which it provides the alert facility for thresholds or specific events which has happened to your coldfusion server.  

To create an alert for any specific event or threshold, coldfusion facilitates with the option of alert configuration in the application. There are four types of alerts in the coldfusion server monitor -

Unresponsive server -

This alert is created when the threads don’t respond in a predefined time period. The counting of these processes is done in the server monitor. This counting is known as the hung thread count.

Slow server -

This alert is created when the total response time is below than the average response time. The server response time is counted in seconds. This alert can be created in case of the unresponsive server.

JVM memory -  

This alert is created when the when the JVM (Java Virtual Machine) compiler uses the memory defined by the application developer. This alert is created in the case of the garbage collection.

Timeout -

This value can be counted in the seconds. This alert is created when the server processes are waiting for the execution by the CPU and it can not respond within the predefined time. This alert can also be triggered in the case of the unresponsive server case.

All alerts are notified by using the following tools -

• send emails.

• creating snapshots.

• kill extra time and space consuming processes.

• and rejecting new requests.

• creating custom CFCs.
