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

Average Receive Rate				Expected Peak Rate for High Traffic
120				140
Table 2. Example values for controlling event traffic for gateways
	Event Send	Adjusted	EventSendThreshold		BufferFlushRate
	Rate	Rate
Gateway A	60	80	80		5400 events per
					minute
					(90 events per second)
Gateway B	60	40	40		3000 events per
					minute
					(50 events per second)
Total Events	120	120	120		140 events per second
Sent to Event
Server

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
