load avg y-axis units a bit odd
list Tom Georgoulias
I have several servers who's load avg is often below 1.0 for days at a time. This morning I happened to check their larrd graphs and noticed that they all had rather odd (at least in the load average sense of things) Y-axis scaling. Instead of a fractional value like 0.2, 0.8, they read 200m, 800m. My BB server with larrd-0.43c, which is graphing the same data (it uses BBRELAY to send it to hobbit), uses the fractional units and I verified my hobbitgraphs.cfg la rrd definitions (seen below) matched those in BB/larrd. Is this something hobbit does? I used the same rrdtool tarball to build both my BB & hobbit servers, so I don't think it's the rrd toolkit.

There's a "-u 1.0" missing in the hobbitgraph.cfg config for the "la"
graph, causing it to dynamically adjust the Y-axis graph when your
load is low. Changing it as follows should fix it:
