   set severity-level-comp =
   set severity-filter medium

 end

More information about above:

enable-severity-filter enable
severity-level-log {no-check | information | notify | warning |error | critical | alert | emergency}
severity-level-comp {>= | = | <=}  # Set the severity level in relation to the log level which they are monitored. 
                                   For example, alerts may be monitored if the messages are greater than, and equal to (>=) Warning log level
severity-filter medium # Set the alert severity indicator for the alert message sent to the recipient
event-time-period {0.5 | 1 | 3 | 6 | 12 | 24 | 72 | 168} # The period of time in hours during which if the threshold number is exceeded, the event will be reported
num-events {1 | 5 | 10 | 50 | 100}  # Set the number of events that must occur in the given interval before it is reported.
enable-generic-text enable  # Enable Grep mode
generic-text <string>  # Enter the text the alert looks for in the log message
