ok, it all looks fairly good, but just needs a few improvements.
1. first thing is that I'd change your crontab to
* * * * * root /home/ram.sh >/dev/null 2>&1
* * * * * root /home/test.sh >/dev/null 2>&1
It still runs every minute, but gets rid of a bit of maths that the cron
process has to do.
2. Don't run it as root. That is generally a bad idea, as running as root you
can make some big accidents. Create another user and run it as that. (this
isn't causing your problem, but is just a good idea when working with unix)
3. The rrd call stuff looks ok at a casual glance (perhaps someone with a more
critical eye could take a look to double check) so I'll assume it running fine.
4. That leaves us with the data gathering. Add in some local logging so you can
see if what you are getting is really a number
update `cat /proc/meminfo | grep "MemTotal\|MemFree\|SwapTotal\|SwapFree" |awk
'{ print $2 }'`
echo $TIMESTAMP `cat /proc/meminfo | grep
"MemTotal\|MemFree\|SwapTotal\|SwapFree" |awk '{ print $2 }'` >> ram.txt
I suspect there might be occurances of Nan (not a number) comming from your
scripts.
I can't reach the 'test.txt' file, so put some similar logging into that.
kind regards
Darryl
