I've tried as you suggested, however it would appear SSE2 is utilised by
the compiler elsewhere:
[336672.388515] traps: netdata[11013] trap invalid opcode ip:484927
sp:bfc4c2a0 error:0
[336672.388543] in netdata[427000+bb000]
I don't have a lot of gdb experience, however this is what I could glean:
(gdb) run
Starting program: /usr/sbin/netdata -D
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib/i386-linux-gnu/libthread_db.so.1".
Program received signal SIGILL, Illegal instruction.

warning: Source file is more recent than executable.
565 rt->green = NAN;
(gdb)
This doesn't make a lot of sense to me - seems to be failing when trying
to load the config for fping. Moving fping.conf out of the way, it then
fails at mdstat.conf:
(gdb) run
Starting program: /usr/sbin/netdata -D
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib/i386-linux-gnu/libthread_db.so.1".

warning: Source file is more recent than executable.
565 rt->green = NAN;
If I move the whole of /etc/netdata/health.d out of the way, it does
make it through loading the config, but one of the threads dies pretty
soon afterwards:
(gdb) run
Starting program: /usr/sbin/netdata -D

Ah. Good old Soekris.
I had a quick look through the source of netdata. The only part of netdata that
makes use of the SSE instruction set is their implementation of the stats.d.
Now, I didn't test this but you could try disabling just this part of the
application. It shouldn't affect the charts.
/etc/netdata/netdata.conf:
[statsd]
enabled = no
I don't know if the compiler automatically used the SSE2 instruction set
elsewhere, but it's worth a try.
