Real-time charts are used to monitor a device at a higher frequency than NMIS is currently monitoring it, they may also be described as "close watch" or "fast polling" charts. In the first release of real-time charts only devices currently being monitored by NMIS can be added.
There are two parts to creating a real-time chart:
The polling definition describes what will be collected and how the data will be presented. The collection defines which node will be polled, which polling definition will be used and defines the parameters around collection and data retention.
