Compressing Troubleshooting Logs from /var/logs to Send to Juniper Technical Support
Problem
You have collected logs on your device and need to send them to Juniper Technical Support. This topic shows you how to compress the logs into a single file for each Routing Engine to more conveniently send the logs.
Solution
You can compress all the log files in the /var/log directories of the master and backup (if
present) Routing Engines into a single tgz file for each Routing Engine, which enables you to send the logs
to JTAC in a convenient package. You can use either the CLI or the
command shell to perform these tasks; because of its ease of use,
only the CLI version is shown here.
- Access the device through the management IP address or
console, typically on the master Routing Engine, RE0.
user@host> - Archive and compress all the log files on RE0 and put
them in
/var/tmp.user@host> file archive compress source /var/log/* destination /var/tmp/re0.tgz/usr/bin/tar: Removing leading `/' from member names - Confirm that the compressed archive file has been created.
user@host> file list /var/tmpbaseline-config.conf gres-tp idp_license_info install jinstall-12.2-20120328.0-domestic-signed.tgz krt_gencfg_filter.txt preinstall_boot_loader.conf re0.tgz rtsdb sec-download vi.recover
On devices with a single Routing Engine, skip to Step 10.
- Log in to the backup Routing Engine, RE1, and access the
CLI.
Note: 1 is appended to the hostname in the prompt to signify that you are on RE1.
user@host> request routing-engine login backup% cliuser@host11>
- Archive and compress all the log files on RE1 and put
them in
/var/tmp.user@host1> file archive compress source /var/log/* destination /var/tmp/re1.tgz/usr/bin/tar: Removing leading `/' from member names - Confirm that the compressed archive file has been created.
user@host1> file list /var/tmpbaseline-config.conf gres-tp idp_license_info install jinstall-12.2-20120328.0-domestic-signed.tgz krt_gencfg_filter.txt preinstall_boot_loader.conf re1.tgz rtsdb sec-download vi.recover %
- Exit the remote login to the backup Routing Engine to
return to the master Routing Engine. Note that the previously appended 1 is removed from the hostname in the prompt to signify
that you are back on RE0.
user@host1> exitrlogin: connection closed user@host1>
- Copy the compressed archive file from RE1 to RE0.
user@host> file copy re1:/var/tmp/re1.tgz /var/tmp - Confirm the presence of the copied file.
user@host> file list /var/tmpbaseline-config.conf gres-tp idp_license_info install jinstall-12.2-20120328.0-domestic-signed.tgz krt_gencfg_filter.txt preinstall_boot_loader.conf re0.tgz re1.tgz rtsdb sec-download vi.recover %
- Copy the files directly from the master Routing Engine to any local host using FTP, SCP, JWEB, or (on some devices) a mounted USB.
