Worksheets and Calculations

Table 1 and Table 2 summarize the values for this example. You can use these
tables as worksheets to assemble the values you measure and calculate for your
environment. All numerical values are expressed in events per second, except
where noted.

Table 1. Example values for controlling event traffic for the event server

Table 2. Example values for controlling event traffic for gateways

(50 events per second)

140 events per second

The following are the calculations to control event traffic:

event server average rate ≥ gateway A events + gateway B events
EventSendThreshold = adjusted send rate for gateway

gateway A

gateway B

BufferFlushRate + BufferFlushRate ≤ event server peak rate

Additionally, you can control event traffic with state correlation provided with
Tivoli Event Integration Facility and the tec_gateway_sce ACP. See the Tivoli Event
Integration Facility User’s Guide
for more information about filtering events with
state correlation.

Configuration File

The gateway configuration file is optional and does not exist on the managed node
until an ACP containing gateway configuration information is distributed to the
endpoint on the managed node. Default values are in effect until they are modified
by distributing an ACP containing gateway configuration information.

The configuration file names and their locations are as follows:

UNIX:

/etc/Tivoli/tec/tec_gateway.conf

Microsoft Windows:

%SystemRoot%:\drivers\etc\Tivoli\tec\tec_gateway.conf
