This article provides example commands to archive and copy logs files between JDM, JCP, and Hypervisor on NFX250.
Below are various archive and copy examples taken from 15.1X53-D45:
Archive all contents of /var/log/ from Hypervisor and move to JDM with a single command:
Execute this command on the Hypervisor:
tar -czvf /var/third-party/hypervisor-CURRENT-DATE.tgz /var/log/* ( collect this file:hypervisor-CURRENT-DATE.tgz from /var/third-party folder on JDM )
Note: /var/third-party folder is shared between JDM and Hypervisor. This means that you can copy a TAR file in the /var/log folder in Hypervisor to the /var/third-party/ folder, and you can collect that same TAR file in /var/third-party from JDM.
Archive and copy /var/log folder from JCP (192.168.1.2) to JDM /var/third-party/ folder while in JDM shell
Tip: Use this option if you have network connectivity from JDM to export logs outside the device.
Execute this command from vJunos0/JCP cli to archive the file:
file archive compress source /var/log/* destination /var/tmp/JCP-CURRENT-DATE.tgz
Execute this command on JDM shell to copy file from JCP /var/tmp location to JDM /var/tmp location:
scp root@192.168.1.2:/var/tmp/JCP-logs.tgz /var/tmp/
Archive and copy /var/log folder from JDM to vjunos0/JCP /var/tmp folder
Tip: Use this option if you have connectivity only from JCP to export the logs from the device
Execute this command on JDM shell to archive /var/log/ folder on JDM:
tar -czvf /var/tmp/JDM-logs.tgz /var/log/*
Execute this command on JDM shell to copy archived file to JCP/vJunos0:
scp /var/tmp/JDM-logs.tgz 192.168.1.2:/var/tmp/
Archive and copy /var/log tar file from hypervisor to vjunos0/JCP /var/tmp folder
Tip: Use this option if you have connectivity only from JCP to export the logs from the device
Execute this command on the hypervisor to archive /var/log folder
tar -czvf /var/tmp/hypervisor-logs /var/log/*
Execute this command on the hypervisor to copy archived file to JCP/vJunos0
scp /var/tmp/hypervisor-logs 192.168.1.2:/var/tmp/
