Citrix NetScaler CLI command cheat sheet

I worked with a Citrix NetScaler engineer a year ago on a case where we had to had to review historic and live logs to troubleshoot an issue and was told that they had a cheat sheet of commonly used commands so I asked her to send it to me.  Below are commands I’ve come to find very useful during troubleshooting:

Uncompress an archived log file:

gunzip newnslog.21.gz

Discover the time period covered by the log:

nsconmsg -K newnslog.21 –d setime

View load-balancing statistics from the archived log:

nsconmsg -K newnslog.21 -s ConLb=2 -d oldconmsg

Extract logging information for a shorter duration:

nsconmsg -K newnslog.21 -s time=12Jan2006:00:00 -k short_log.nsl -T 1200 -d copy

Start the log process for newnslog:

nsconmsg -k /var/nslog/newnslog -T 172800 &

If you want to:

View the time span of the current newnslog file:

nsconmsg -K newnslog -d setime

View the time span of the archived newnslog file:

zcat filename | nsconmsg -K pipe -d setime

View events in the current newnslog file:

nsconmsg -K newnslog -d event

View console messages in the current newnslog file:

nsconmsg -K newnslog -d consmsg

View counter values in the current newnslog file:

nsconmsg -K newnslog -d stats

To display integrated caching statistics in the shell:

nsconmsg -K newnslog -s ConIC=1 -d oldconmsg
