16.5.2 Event Filter Actions

You must associate at least one action with each event filter. The following action types are available:

• Trap: Send SNMP V1 and V2 traps for events matching particular filter criteria.

• Email: Send an email for events matching particular filter criteria.

Setting Match

Criteria

Determines whether the incoming event should be filtered or not. If a field is left blank, it is

automatically matched. The condition for the event filter to be applied is that all the match criteria

specified should be satisfied. If one criteria fails, the filter will not be applied.

You can use the following expressions to specify match criteria:

• Wildcard - Asterisk (*): A match of 0 or more characters of any value.

• For example, “Failed*” will match any string starting with Failed. Expressions like *Failed,

Fai*led*, or * can be used which have relevant meaning.

• Negation - Exclamation (!): Used at the start of the field to specify exclusion of events

matching this expression. For example, !Failed will exclude strings starting with “Failed”.

• Separator - Comma (,): Multiple values can be specified for a single match criteria for

separating them with commas (a logical OR). For example, Critical, Major will match a string

which is either Critical or Major. For another example, if all the objects with names starting

with "abc" or "xyz" are required, then property key -name and value abc*,xyz* is given

• Comma (,) with !: When used together, this will match the string by using a logical AND.

For example, the property key-name of *xyz,!abc* must match all names that end in xyz

AND begin with abc.

• && (Double Ampersands): This is also used for searching objects where a single value should

be matched with many patterns. For example, if all the objects with names starting with

either "abc" or ending with "xyz" are required, then property key -name and value

abc*&&*xyz is given.

• \ (Back Slash): This is used when the name of the object itself contains a comma. This

character is called an escape sequence, since it avoids searching of the objects, as if it were

two different names. For example, if an object with name "a,b" has to be searched, then the

property key - name and the value a\,b is given.

• <between>"value1" and "value2": This is used to get objects with some numeric values

within a specific range. For example, if object names with poll interval value ranging from 300

to 305 is required, then the property key - pollinterval and the value as 300 and 305 is given.

Note that the first number is smaller than the second number. Only the values in between

the given values, including the limits, will be matched.
