Alerts Tab

The Alerts tab displays detailed information about all the SMART Alerts found by the system. The Alert List at the top of the central pane displays the number of alerts for each severity level, corresponding to the Alert Filter settings in the left pane.

Alert severity calculation

The severity of the alert is based on the alert score. To see the alert score, hover over the alert severity icon.

•
Critical severity has a score of 98 – 100.
•
High severity has a score of 93 – 97.
•
Medium severity has a score of 85 – 93.
•
Low severity has a score of 75 – 84.

Alerts that do not meet the minimum threshold of 75 are discarded as false positives.
