-a specifies a comma-separated list of attributes or metrics names. The default is all.
-w specify one or multiple selection string that can be used to select events. The operators ==, !=, =,!,>,<,>=,<= are available. Wildcards % and _ are supported in the pattern string. % allows you to match any string of any length(including zero length) and _ allows you to match on a single character. The valid attributes are eventtype, monitor, monnode, application, component, id, severity, message, rawdata, comments. Valid severity are: Informational, Warning, Critical.
Operator descriptions:
== Select event where the attribute value is exactly this value.
!= Select event where the attribute value is not this specific value.
=~ Select event where the attribute value matches this pattern string. Not work with severity.
!~> Select event where the attribute value does not match this pattern string. Not work with severity.
