Implementing Specific-Event Suppression From a
Primary Collector
Implementing Specific-Event Suppression From a Primary
Collector
To enable specific-event suppression in the primary collector, use one of these
methods:

While the primary collector ($0) is running, use the FILTER keyword of
EMSCCTRL to specify a filter table or compiled filter that contains the event-
suppressing directives (this command enables PLF).

While $0 is running, invoke a program that uses the SPI interface to modify the
filter criteria (for example, a program that contains an ADD command with the
event-suppressing filter table or compiled filter as its object).
Implementing Specific-Event Suppression From an Alternate
Collector
To enable specific-event suppression in an alternate collector, use one of these
methods:

When the alternate collector is first started, use the FILTER keyword of
EMSACOLL to specify a filter table or compiled filter that contains the event-
suppression directives. (This command enables PLF.)

While the alternate collector is running, use the FILTER keyword of EMSCCTRL to
specify a filter table or compiled filter that contains the event-suppression
directives. (This command enables PLF.)

While the alternate collector is running, invoke a program that uses the SPI
interface to modify the filter criteria (for example, a program that contains an ADD
command with the event-suppressing filter table or compiled filter as its object).
Implementing Specific-Event Suppression From a Distributor
To enable specific-event suppression in a distributor, use one of these methods:

When the distributor is first started, use the FILTER keyword of the EMSDIST
program to load the event-suppressing filter table or compiled filter. For a detailed
description of EMSDIST command syntax options, see Section 13, EMS
Programs.

If the distributor is already running, invoke a program that uses the SPI interface to
modify the filter criteria (for example, a program that contains an ADD command
with the event-suppressing filter table or compiled filter as its object).
