Here is an example of filtering out events that include the string 'Teardown'
12:26:35.000 PM 2015-08-10T12:26:35-04:00 host-706-zz-ASA5520-A : %ASA-6-305012: Teardown dynamic UDP translation from inside:10.1.1.1/51971 to outside:x.x.x.x/51971 duration 0:00:31
on your heavy forwarder:
$SPLUNK_HOME/etc/system/local
props.conf
[host::xyz]
TRANSFORMS-null = nullteardowns
transforms.conf
[nullteardowns]
REGEX = Teardown
DEST_KEY = queue
FORMAT = nullQueue
restart heavy forwarder after the change.
Note: if this is syslog data , and you are filtering on host , use the host name of the syslog server itself as this will be processed before the actual host name of the sending device is assigned.
