The SNMP Monitor tests an SNMP device's ability to respond to an information request and its responsiveness.
It sends a request for a fixed piece of information: uptime (1.3.6.1.2.1.1.3.0), and waits for a valid response in reference to the original request.
Note: A "Community" is a keyword that an SNMP manager must send with all queries. The SNMP agent will not respond unless this keyword is correct.
Note: Commonly, SNMP agents have a list of IP addresses that they will talk to provided that the Community keyword is correct . You may have to configure each SNMP agent that will be monitored to include the IP address of ipMonitor's host machine.
This Monitor:
- Considers the specified resource unavailable after a specified number of seconds.
- Persistently tests the resource at specified intervals.
- Disallows testing during a maintenance period.
- Waits for a specified number of failures to occur before starting alerts.
- Switches testing intervals, from "responding correctly" to "not responding correctly". Configurable intervals allow you to test more or less aggressively in the event of failure.
- Stops alerting after a specified number of alerts.
- Has a placeholder for a WinNT Service Name or any other information required by a recovery script.
