IBM Enterprise Console manual tec/gatewaycache@EventServer#tmr-central, EventSendThreshold

The following example illustrates how the Windows path notation can be expanded:

c:\winnt\system32\drivers\etc\Tivoli\tec\tec_gateway.conf

The configuration file defines the behavior of the gateway. The configuration file can have the common keywords described in “Keywords” on page 9, as well as the following custom keywords:

BufEvtPath Specifies the gateway to buffer events at this location if it cannot forward them to the event server. Because a single gateway can forward events to multiple event servers, it must have an event buffer file for each of those event servers. This allows the gateway to send events to the correct event servers when it re-establishes connections to them and flushes buffers. These buffer files are created by the gateway appending the event server location to the name of the file defined with the BufEvtPath option.

The following example shows how to specify this option:

ServerLocation=@EventServer#tmr-central

BufEvtPath=/etc/Tivoli/tec/gateway_cache

In the example, the actual file created is /etc/Tivoli/

tec/gateway_cache@EventServer#tmr-central.

More than one buffer file might be created at the gateway, depending on how many event server locations are configured by the adapters sending events. For each different server location, a separate buffer file is created. Continuing with the example, if the gateway received an event from an adapter that specified server location @EventServer#tmr-east, an additional file named /etc/Tivoli/tec /gateway_cache@EventServer#tmr-eastwould be created.

The default is the following:

UNIX: /etc/Tivoli/tec/cache@EventServer#region

Windows: $DBDIR/cache.dat@EventServer#region (on managed nodes)

$TIVOLIHOME/tec/$(AC_TYPE).cache@ EventServer#region (on endpoints)

Note: The keywords Filter, FilterCache, and FilterMode can be used for the gateway. For reducing network load and improving performance of the managed node containing the gateway, it is better to filter events as close to the source as possible; that is, by specifying filter options in adapter configuration files.

EventSendThreshold

Specifies the maximum number of events per second to send to the server. Use this parameter with the BufferFlushRate keyword.

GatewayAckInterval

Specifies the timeout interval, in seconds, to wait for the
