Thanks for responding, Bernard. Indeed my cron job grabs one counter reading and posts it immediately via gmetric.
The job runs once per minute. One thing I should do is create a logfile of the valies being posted. I'll take care of this tonight.

I wonder if you could merge the data collection with your gmetric cronjob. Also, how frequently is your cronjob run?

Here are my day and hour graph: http://www.greenberg.org/graphs So my hour graph shows individual points with spaces between them, but they don't correspond very well to the data I'm seeing. My day graph seems t o reflect the magnitude of the data in the non-zeo cells. I'd really appreciate an explanation of what's going on, and what the best way is to clean this up.
