Article ID: KB27285 KB Last Updated: 29 Oct 2019Version: 3.0 Summary:

This article contains a list what to collect for Junos Content Encore

Symptoms:

What information should I collect to assist in troubleshooting prior to opening a case?

The goal of this document is to reduce the time spent on initial data collection and reduce time to resolve by providing a comprehensive list of what to collect or gather to troubleshoot an issue.
 
Solution:

Please collect the following for Junos Content Encore issues:

 

A. Tech Support Report

Ideally the best data to collect is the Tech Support Report. It is available in the WEB UI under the System Config tab:



The Snapshots menu also on this screen contains any coredumps. If any are present, please download those as well.

Warning:  The tech-support log can be very large, gigs of data. Use KB23337 - How to upload large files to a JTAC Case to upload the tech-support and any snapshots available.  If it is not possible to collect and send the Tech Support Report in, then collect the following and attach it to your case:

mfc # show running-config
mfc # show accesslog default last 500
mfc # show cachelog last 500
mfc # show log
mfc # show counters
mfc # show service
 


B. Additional data to collect:

If the issue is with a specific Namespace, please collect the following. (example: namespace tproxy)

mfc # show namespace tproxy counters
login to the shell with "_shell"
[admin@mfc ~]# cat /var/log/nkn/access.log | grep trpoxy
[admin@mfc ~]# cat /var/log/nkn/cache.log | grep trpoxy


If the issue is with a particular source or client IP address and an origin server. Collect a packet capture as follows:

mfc (config) # tcpdump -nn -i eth0 -S -s 1024 host 10.10.10.10 or host 20.20.20.20 -w mfc.pcap

Run the problem traffic, then Ctrl-c to stop the capture.

You can then tftp, ftp, sftp or SCP the capture off the MFC to view in wireshark.
(config) # file tcpdump upload mfc.pcap tftp://30.30.30.30/mfc.pcap


Attach your data to the case or SFTP as per KB23337 - How to upload large files to a JTAC Case for JTAC to reference.
