Requests with Errors
The Requests with Errors report lists the templates that generate an error. The report includes the path of the template,
and the number of times errors occurred in that template. For the most recent error, the report indicates the time of
the error, the error message, CFML stack traces, and Java stack traces. You can view a list of templates or details about
an individual template. The detailed information includes the CFML stack trace.
Requests Timed Out
The Requests Timed Out page lists the templates that timed out. The report includes the path of the template, the
number of times the template timed out, the most recent response time for the template, the time when the template
was most recently used, the most recent estimated request size, and the CFML stack trace. A Java stack trace is not
provided because time outs can only occur within CFML. You can view a list of templates or details about an individual
template. The detailed information includes the CFML stack trace.
Alerts
The Alerts report lists all the snapshots that alerts generate.
Alert Configuration
The Alert Configuration page lets you specify the thresholds for when to generate an alert. Alerts provide warnings of
potential problems, including a slow server or an unresponsive server. The slow-server alert is triggered when the
server’s average response time exceeds a specified limit. The unresponsive-server alert is triggered when more than a
specified number of threads are busy for more than a specified number of seconds. The unresponsive-server alert
creates a snapshot file, which lets you determine where request threads are unresponsive. Both types of alert let you
run a custom CFC when the alert is triggered, which lets you provide your own automated response to an alert
condition. You can specify whether to send an e-mail notification when an alert is triggered, and to whom. You can
also specify the user name and password to log in to the server that is specified on the Mail page of the ColdFusion
Administrator.
Snapshots
The Snapshots report lists all snapshots that are triggered. Snapshots include details about the ColdFusion server at the
moment the snapshot is triggered. These details include:
•
The time and reason the snapshot was triggered
•
Whether profiling and memory tracking are enabled
•
How many running and queued requests exist at the moment of the snapshot
•
Information about memory usage, including:
•
JVM memory usage
•
Server, application, and session scope memory usage
•
Throttle-queue size and memory usage
•
Information about cached queries
•
Status of the database pool
•
The Java stack trace
Snapshots are triggered when one of the following occurs:
