n is either 1 or 0. The default value is 0.
When SNMPEnabled is enabled (n = 1), the SNMP agent automatically starts when InterSystems IRIS® data platform starts up.
To enable SNMP monitoring, select Start SNMP Agent at System Startup. You must also have the %Service_Monitor enabled on the Services page (System Administration > Security > Services).
Changing This Parameter
On the Monitor page of the Management Portal (System Administration > Configuration > Additional Settings > Monitor), select Start SNMP Agent at System Startup to enable this setting. There is also a shortcut to enable %Service_Monitor.
Instead of using the Management Portal, you can change SNMPEnabled in the Config.Monitor class (as described in the class reference) or by editing the CPF in a text editor (as described in the Editing the Active CPF section of the “Introduction to the Configuration Parameter File” chapter in this book).
