Create thresholds and alerts

Last published : Sep 21, 2026
You can set thresholds and alerts to monitor the state of a NetScaler instance. You can set thresholds on counters and monitor instances and entities on managed instances.
When the value of a counter exceeds the threshold, NetScaler Console generates an event to signify a performance-related issue. When the counter value matches the clear value specified in the threshold, the event is cleared, which means that the particular threshold has returned to its normal state.
You can also associate an action with the threshold. Actions include sending an alert, email, or SMS notification. When the threshold is breached, NetScaler Console performs the action you define is taken automatically like enabling an alert and sending an email or SMS notification.
