Execution Duration Measurements
SURVIVOR provides a mechanism for measuring the duration of module execution. This can be useful for, as an example, measuring the response time of services. ### Standard Check Modules Standard check modules are responsible for performing their own duration measurement, as described here. Routines are provided with the standard module libraries to transparently handle duration measurement in most circumstances, as described here. ### Composite Checks Duration measurements for composite checks are calculated by adding together the duration measurements for each component check. (This is subject to change in a future release.) ### Other Modules Other types of modules do not currently support duration measurement. $Date: 2006/11/20 02:47:21 $ $Revision: 0.2 $ | keywords
