Passive Monitoring

NetEye’s monitoring strategy incorporates both Passive and Active monitoring approaches. While Active monitoring allows to proactively monitor your infrastructure, a solution provided for performing Passive monitoring creates a complete view of your infrastructure state, performance and behavior without actively interacting with it.

In the process of passive monitoring, NetEye will analyze the data received from your devices, process it and then, if required, will generate and execute actions based on your needs and preference.

Passive monitoring proves to be useful when monitored devices and infrastructure are not supporting the installation of an agent for active monitoring, and it is possible to tune them to send particular events to the NetEye for the following processing.

Passive monitoring is more resource-efficient compared to active monitoring. It consumes minimal resources as it works with existing data flows. Additionally, it doesn’t introduce additional traffic or load. This makes it perfectly suitable for critical production environments where minimizing disruptions is crucial.

To assist in running passive monitoring processes, i.e. receiving data from various sources without implementing custom processors, Tornado software was integrated into NetEye.

Tornado, a Complex Event Processor, receives reports of events from data sources such as monitoring, email, and telegram, matches them against pre-configured rules, and executes the actions associated with those rules. These may include sending notifications, logging to files, and annotating events in a time series graphing system.
