Some links to myself on the newnslog files (these are binary log files; high precision; need a tool called nsconmsg to view them).
- NetScaler Master Class of April 2017
- Useful blog posts:
- https://github.com/uncon/wiki/blob/master/netscaler/nsconmsg.md (has a good list of all the options)
- https://www.franken.pro/blog/citrix-netscaler-cli-commands (a very good post with examples)
- https://support.citrix.com/article/CTX113341 – from Citrix
A typical format of the command is like this:
|
1 |
nsconmsg -K /path/to/newnslog -d <operation> |
The <operation> can be one of these (this is just a copy-paste from nsconmsg -?):

The newnslog files are rotated every 2 days (or a certain number of events if I remember correctly). The older ones can be accessed by putting a path to that file (e.g. /var/nslog/newnslog.28.tar.gz in the command above). This will extract the file and show the logs. The Citrix page says we have to extract the logs first, but am guessing that’s old info.
That’s all for now. Will add more to this post later …
