How can i get bigger graphs?

Hello,

I was wondering I can I get bigger graphs. Ronny once showed my, but I forgot what to change :). What I mean specifically is how can I get a wider shown area for graphs on the "Resource Graphs" part? I want them with a bigger size (for people having "vision problem" like me :))

My idea was to double the numbers for datacollection-config.xml (like here below):

<rrd step="300">
            <rra>RRA:AVERAGE:0.5:1:4032</rra>
            <rra>RRA:AVERAGE:0.5:12:2976</rra>
            <rra>RRA:AVERAGE:0.5:288:732</rra>
            <rra>RRA:MAX:0.5:288:732</rra>
            <rra>RRA:MIN:0.5:288:732</rra>
        </rrd>
 

but this didn't work as I expected. (graphs still remain small).

Really good question! I think, Ronny showed me this trick too... Unfortunately I forgot it :-)

I've persisted it in my outsourced memory ;)

Great solution! :) Thanks for sharing. Your "outsourced memory" it's on my feed! ;)
Thanks Ronny! It seems that StrafePing graphs have to configured seperately:

response-graph.properties
report.strafeping.name=StrafePing
report.strafeping.columns=strafeping
report.strafeping.type=responseTime, distributedStatus
report.strafeping.command=--title="StrafePing Response Time" \
 --height 200 \
 --width 1000 \
Yes, you're right, there are graphs which overwrite the global rrd command by injecting their own --width and --height. You can just remove it, using the global setting, leave it or set it to something different.
