The logfile directive is deprecated for version 2.x configurations. Please enable the use_logd directive instead.
The logfile directive configures a log file. All non-debug messages from Heartbeat will go into this file.
A sample logfile directive is shown below:
logfile /var/log/ha-log
Configuring a log file (instead of using syslog logging) can cause Heartbeat to block for several seconds under heavy load. This can affect the deadtime required for the system.
