Event Types
Choosing and Defining Events
The Event Triggers feature is accessed from PHP Intelligence | Event Triggers.
The fields that make up the "Configure Event Triggers" table are:
ƒ
Event Type - The type of event under the rules defined, will produce an alert in the
monitoring system.
ƒ
Active - When enabled for a specific event, Zend Monitor (node) will report alerts when they
occur (This gives the user the right to disable an event for a particular server).
ƒ
Rules - Defines the conditions under which an event will produce a report. For example,
(Red) Script Runtime Exceeds 500 Seconds means that the system will generate a critical
(red) event-for Slow Script Execution (Absolute) type events, when meeting the condition (>
500 sec.).
Note:
Define thresholds for both moderate and severe events although, some events have only one level of
severity (like function error).
ƒ
To define whether Zend Monitor will report a specific event, enable/disable the event in the
Active column of the Define Event Triggers table.
ƒ
To save the changes to Event Trigger definitions, click Save Rules.
The database will update with the changes.
Each event type has its own advantages and characteristics.
Note:
Events marked as "Performance Monitoring Events" have a special role in optimizing web application
performance. See "Implementing the Performance Lifecycle".
Each Event Type has its own advantages and characteristics. Listed below are the different Event
Types, their descriptions and recommended usage.
The following is a list of event types, click on the event name for more information about a specific
event:
ƒ
Slow Script Execution (Absolute and Relative) - Generates an event when executing a script
exceeds defined limits or is lower or higher than the average script execution time.
ƒ
PHP Error - PHP Errors are used to identify all types of PHP errors. This type of event is useful
in QA processes to identify problems that may have slipped through the cracks during
production.
ƒ
Java Exception - Java exception events increase the visibility of issues originating from the
Java Side by indicating when uncaught Java exceptions occur in Java Code invoked from PHP
using the Java Bridge.
ƒ
Function Error - Generate a severe event when an error in one of the specified PHP Functions
occurs
ƒ
Slow Function Execution - Identify bottlenecks within functions.
