I'm trying to add a legend that reports LAST and MAX for 'a' and 'g'.
everything below is functional. I have gone through a few variations of
the RRDs::graph function with no luck.
my rrd definition:
RRDs::create ($rrdfile, "--start", $time, "--step", 120,
"DS:auth:GAUGE:600:0:99999", # auth = authenticated users
"DS:guest:GAUGE:600:0:99999", # guest = guest users
"RRA:MAX:0.5:1:1440", # 48 hours, 2 minute samples
"RRA:MAX:0.5:30:240", # weekly, 10 days of 1 hour samples
"RRA:MAX:0.5:48:336", # monthly, 8 weeks of 4 hour samples
"RRA:MAX:0.5:288:730", # yearly, 2 years of 1 day samples
"RRA:MAX:0.5:2016:1040", # 20 years of 1 week samples
);
My current working graphing:
RRDs::graph "$apgraph$graphfile48",
"--title", $ap,
"--start", "now-48h",
"--width=200",
"--height=50",
"--vertical-label=Active Users",
"DEF:a=$rrdfile:auth:MAX",
"DEF:g=$rrdfile:guest:MAX",
"AREA:a#FFCC33:Authenticated Users ",
"AREA:g#3366FF:Guest Users:STACK",
"--lazy",
;
