Class IncrementalMonitor

java.lang.Object

org.qbroker.monitor.Monitor

org.qbroker.monitor.IncrementalMonitor

All Implemented Interfaces:

MonitorAction, MonitorReport

public class IncrementalMonitor
extends Monitor

IncrementalMonitor monitors the incremental of a number to see if it is out of the ranges. It supports various schemes to get the text containing the number. The number is supposed to be increasing except for a reset. The output may contains multiple lines. IncrementalMonitor parses the text line by line to get the numbers. Then it aggregates them according to the specified operation.

It supports v1 and v2c SNMP query. But it requires Java 1.4 or above due SNMP4J.
