I run a command like:
rrdtool graph - --start -3600 --end N DEF:m0='load_five.rrd':'sum':AVERAGE PRINT:m0:MAX:%.2lf which should simply print the maximum load over the last hour. This works fine on 1.0.38 (the only other version I've tested on), but not in 1.2.23. At someone's suggestion, I tried outputting to /dev/null instead of standard out and the PRINT lines then show up on standard out. But that's not portable, so what's the solution here? Thanks, Matt Chambers
