NumberMonitor

java.lang.Object
- org.qbroker.monitor.Monitor
- - org.qbroker.monitor.NumberMonitor

All Implemented Interfaces:

MonitorAction, MonitorReport
```
public class NumberMonitor
extends Monitor
```
NumberMonitor monitors a number to see if it is out of the ranges. It supports various schemes to get the text containing the number. The output may contains multiple lines. NumberMonitor 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.
