The smaller the time interval, the more granular the data.
You can customize the display labels for each of the attributes here. In a typical workflow the monitors extract data from the monitored device and send it to the rules engine.

Select the parameters you need to monitor from the list of attributes shown. However, if a rule is violated, a message is immediately sent to the notification server to alert the user about the rule violation.
