NetSpyGlass has a built-in framework that can collect, store, process, and react to the information extracted
from Syslog messages. For example, NetSpyGlass cluster configured to collect and process Syslog messages from network
devices can detect interface flapping, device restarts, fabric channel errors or brute force attacks and other
events registered in device logs. The system can send notifications in a near real-time manner to log, email,
Slack, Pager Duty, or ServiceNow when these events happen.
