I would like to know how to use the compression feature of nfdump 1.5.7.
I'm not sure where it's documented but I don't seem to be able to find
in the mail archives or in the man pages for it.
1. How do you enable it? It seems that it should be an config option
in nfsen.conf but I don't see it. I am using nfdump 1.5.7 with a
current svn snapshot of nfsen. It doesn't look like compression is on
by default.
Here is a current file:
[root]# /usr/local/svn/nfdump/bin/nfdump -v nfcapd.200803101335
File : nfcapd.200803101335
Version : 1 - not compressed
Blocks : 1
Records : 15900
Here is a current nfcapd process:
netflow 22959 1 0 Mar09 ? 00:00:00
/usr/local/svn/nfdump/bin/nfcapd -w -D -I rca-cal-md-1 -p 10060 -u
netflow -g apache -B 200000 -l /data/nfsen/profiles/live/rca-cal-md-1 -P
/data/nfsen/var/run/rca-cal-md-1.pid
2. Once enabled, what performance impact will it have when running
nfsen? Longer query times etc?
3. Anything else to watch out for?
If I have missed the documentation, please just point me to it.
Thanks.
