System Status Log File Overview

The system writes a system log file for each fabric node to provide troubleshooting and monitoring information. See System Status Log File.

The system administrator can customize the information that is collected in the system log file. See Customizing Node System Status Log Checking.

The system administrator can download the latest log files for each fabric node when logged into an appliance. See Downloading System Log Files For an Appliance.

In each operating mode, the system administrator can customize the default log files that are download from an appliance. See Customizing Node Log Files To Download.

System Status Log File

Approximately once a minute, the system checks and writes a status log file SystemStatusLog for each fabric node by default. Each log file consists of system status, such as the disk, CPU, and memory usage information, as shown. Junos Space writes each system status log file to /var/log/SystemStatusLog.
