This watermark does not appear in the registered version - http://www.clicktoconvert.comSNMP Data Collection OpenNMS uses RRDtool (the end result ofMRTG) to store and graph SNMP data. Configurable: the polling interval, datacollection and how the data is stored. Custom Reports: Almost any report possiblewith RRDtool can be built into OpenNMS.

Automatic actionscan be built to execute on event reception. Events can trigger Notifications Notifications walk a "destination path" toinsure that alerts reach the proper people.
