Event Filtering

Event filtering is identifying and discarding events which are irrelevant to the Iotellect. For instance, a number of bottom-of-the-range devices may be difficult to configure and occasionally send events of no interest to Iotellect. For example, a desktop printer indicating it needs a paper refill.

There are several ways to filter unnecessary events in Iotellect Server:

  • Many device drivers and plugins capable of receiving events from diverse hardware provide mechanisms for skipping certain events or downgrading their severity. For example, the Syslog plugin has a Severity Conversion Table that allows the level of Iotellect events to be fine-tuned as Syslog messages are received.

  • Events may be excluded from processing, storage, or routing chains by configuring a Pre-filter in Event Processing Rules.

  • Certain events can be excluded from being displayed at the user interface level. Event Filters allow criteria to be set in order to only display relevant events during real-time event monitoring and event history browsing. Secondly, most system facilities that are involved in event mining allow for the specification of various filtering criteria, from simple (based on start/end timestamps and minimal levels) to flexible (ones based on expressions).
