Setting Parameters for Central Logging

By default, central logging is not active on every application server. Before you can activate central logging, ensure that the log parameters are the same in the central system and on every instance. The system parameters that control central logging all start with the prefix rslg.

To set the rslg parameters you can edit the profile on the current application server or the DEFAULT.PFL file on the central application server. We recommend that you edit the DEFAULT.PFL file.

Procedure

Editing DEFAULT.PFL

This is how you set the parameters for central logging using the DEFAULT.PFL profile:

Display the rslg parameter values in the central system.
To do this, select Environment Display SAPPARAM on the start screen for the system log.
Check the values of the dollowing parameters:
rslg/collect_daemon/host

rslg/collect_daemon/listen_port

rslg/collect_daemon/talk_port

rslg/send_daemon/listen_port

rslg/send_daemon/talk_port

These parameters must be set and must be identical for the central system and all instances.

Below you find information on the values permitted for each parameter. Many of the rslg parameters are already set depending on your installation.
Edit DEFAULT.PFL and ensure that all the parameters are correct.
Save your changes.
The system sets the rslg parameters in the central system and in all instances.

After you have checked if the system profiles are set correctly you have to start the send and collect processes. For information, see Starting System Log Processes.

Parameters for Central Logging

The rslg parameters are defined as follows:

`rslg/collect_daemon/host`	Specifies the name of the node for the central log.
`rslg/collect_daemon/listen_port`	Specifies the listen port for the collect process. By default, this parameter is set to: 14< SAPSYSTEM number> Caution Ensure that the listen port is the same for all instances in your SAP system. End of the caution.
`rslg/collect_daemon/talk_port`	Specifies the talk port for the collect process. By default, this parameter is set to: 15< SAPSYSTEM number> Caution Ensure that the talk port is the same for all instances in your SAP system. End of the caution.
`rslg/send_daemon/listen_port`	Specifies the listen port for the send process. By default, this parameter is set to: 12< SAPSYSTEM number> Caution Ensure that the listen port is the same for all instances in your SAP system. End of the caution.
`rslg/send_daemon/talk_port`	Specifies the talk port for the send process. By default, this parameter is set to: 13<SAPSYSTEM number> Caution Ensure that the talk port is the same for all instances in your SAP system. End of the caution.
`rslg/send_daemon_autostart`	Leave the value of this parameter at 0.

The send process also uses the following dsystem profile parameters. Do not change the default value of this parameter:

`rslg/collect_daemon/exe_file`	Specifies the executable file for the central collect process.
`rslg/send_daemon/exe_file`	Specifies the executable file for the send process.
`rslg/send_daemon/pid_file`	Identifies the file that is initialized when starting the send process.
`rslg/send_daemon/status_file`	Identifies the internal status file lead by the send process.
