Subject: [cacti-user] Y-Axis Units

Hi All,
We have a few graphs with some seemingly incorrect y-axis units. Once of 
our graphs (Tomcat - Connection Rate [from the Tomcat Stats plugin]) is 
showing a y-axis range of 0 *M* - 14 *M* requests/second. And some 
machines have some datapoints right at 14 M.

The documentation indicates that "M" = mega (same as million):
http://www.cacti.net/downloads/docs/html/graph_templates.html

I doubt that these machines are getting 14 million Tomcat requests/sec.

Does anyone have any idea of what could be going on?

BTW, here is how the graph was created:
/usr/bin/rrdtool graph - \
--imgformat=PNG \
--start=-86400 \
--end=-300 \
--title='nw031 - Tomcat - Connection Rate' \
--base=1000 \
--height=120 \
--width=500 \
--alt-autoscale-max \
--lower-limit=0 \
--vertical-label='Requests / Second' \
--slope-mode \

--font AXIS:7: \

Thanks In Advance,
Mike
