I don't know if that could be done in a config file, but it certainly can be done by altering the source. Take a look at hobbitd/hobbitgraph.c. Near the top there's a bunch of defines that tell rrdtool how to select the data:

#define HOUR_GRAPH "e-48h" #define DAY_GRAPH "e-12d" #define WEEK_GRAPH "e-48d" #define MONTH_GRAPH "e-576d"

"e-48h" means "end-of-data minus 48 hours", which is the start of the range, the end of the range being the end of the data. Change those numbers to whatever suits you best - i.e. e-24h, e-7d, e-30d & e-365d.

You'll also want to look further down for blocks like this:

 if (strcmp(val, "hourly") == 0) {
               period = HOUR_GRAPH;
               persecs = 48*60*60;
               gtype = strdup(val);
               glegend = "Last 48 Hours";
 }

and fix those up. I guess that would be:

               persecs = 24*60*60;

and glegend = "Last 24 Hours";

for the 24 hour graph. Similarly for DAY_GRAPH, WEEK_GRAPH & MONTH_GRAPH. Go back up to the main source directory and re-run make, then copy hobbitd/hobbitgraph.cgi over to hobbit's server/bin directory.

Seems to work fine for me - I might even keep it like this... :)

I should have been a clearer in my post here. When clicking on the graph in the Trends page, is there a way to change the default historical times? Instead of 48 hrs, 12 days, 48 days, and 576 days, can the graphs be set to 24 hrs, 7 days, 30 days, 365 days?

Thanks,
