Overview
ClearPass supports standard host MIB which provides up/down, disk, CPU, memory and a variety of other alerts. This can be monitored by Airwave or a 3rd party tool supporting SNMP. In addition we can send events and alerts through syslog to any SIEM (or Airwave) where you can construct the appropriate filters needed to trigger alerts, etc. Finally we have our own internal alerting capabilities through Insight (the reporting engine). Insight allows you to send an email/sms based on an alert, this email could obviously trigger some other workflow in 3rd party systems.
