Viewing Log Information

This section describes the log path and related permission information.

MEF Center Logs

After MEF Center is successfully installed, the log paths are as follows (the default installation path is /var):

Installation logs: Log path/mef-center-log/mef-center-install
Run logs: Log path/mef-center-log/mef-center-install/mef-center-install-run.log

The time read by mef-center-install-run.log is the host time, and the time read by other MEF Center logs is the container time.
Operation logs: Log path/mef-center-log/mef-center-install/mef-center-install-operate.log
Logs of each module: Log path/mef-center-log/Module name

Viewing MEF Edge Logs

For details about process run logs or software installation logs generated during MEF Edge installation, see Table 1. If the log root path is the default path /var/alog, logs are recorded in /var/alog/MEFEdge_log. The permission on the log folder of each component is 750, and the permission on the log file is 640. The time when MEF Edge logs are read is the host time.
