request system debug-info
Syntax
request system debug-info <node node-name>
Syntax (Junos EVO devices)
request system debug-info <mode custom | lite | normal> <since duration> <node node-name>
Description
Collect debug information from Junos OS Evolved, such as logs. Logs are stored in the /var/tmp/ directory. Debug collector collects cores, application traces, configurations, commits and so on. It also collects outputs from CLI and CLI-PFE commands. You need to login to the device as root user to use this command. Enter the root password and confirm it when requested.
Options
node node-name |
(Optional) Identifier of the node. If a value for |
mode |
|
since |
Specifies the log duration. The supported format is yyyy-mm-dd or #d (ex: 2d) or #h (ex: 5h). By default, you can collect the logs for a duration of 90 days. |
Additional Information
Debug collector takes maximum time while collecting journal logs and traces. You can
use the request system debug-info command for quick debug
collection from /var/tmp in the following sample format:
-
request system debug-info node re0,fpc0,fpc1,fpc2 since 1h—Normal mode with minimal journal and trace logs collection from master RE and all FPCs. -
request system debug-info node re1 since 1h—Normal mode with minimal journal and trace logs collection from backup RE only. -
request system debug-info mode lite node re0,fpc0,fpc1,fpc2 since 1h—Lite mode with minimal journal and trace logs collection from master RE and all FPCs. -
request system debug-info mode lite node re1 since 1h—Lite mode with minimal journal and trace logs collection from backup RE only.
To view the debug_collector.log file:
-
Go to the /var/tmp/ directory.
root@host:~# cd /var/tmp root@host:/var/tmp# ls debug_collector_2017-11-20_13_16_45.tar.gz
-
Uncompress the /var/tmp/ file.
root@host:/var/tmp# tar -xf debug_collector_2017-11-20_13_16_45.tar.gz root@host:/var/tmp# ls debug_collector_2017-11-20_13_16_45 debug_collector_2017-11-20_13_16_45.tar.gz
-
Go to the /var/tmp/debug_collector_timestamp directory.
root@host:/var/tmp# cd debug_collector_2017-11-20_13_16_45 root@host:/var/tmp/debug_collector_2017-11-20_13_16_45# ls debug_collector.log re0 re1 fpc0
-
Look at the log file.
