Subject: [PATCH] pmlogger_farm: add default configuration file for farm
|
|
|
5823b6 |
loggers
|
|
|
5823b6 |
|
|
|
5823b6 |
Provide a mechanism whereby the farm loggers can be configured.
|
|
|
5823b6 |
There has been reluctance in the past to sharing configuration
|
|
|
5823b6 |
of the local primary logger, so these are now done separately.
|
|
|
5823b6 |
Makes sense to me as the primary pmlogger may need to use more
|
|
|
5823b6 |
frequent sampling, may not want to allow remote pmlc, etc.
