Change graphing on Trends link 🔗 link

Is it possible to change the graphing on the trends link to 1 week instead
of 48 hrs?  Or is it possible to have multiple graphs on this page?

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?

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... :)

Ralph,

I gave your suggestion a shot today, and just when I think I am making
progress learning Linux, I get slapped in the face.  I found the
hobbitgraph.c and made the changes as you outlined below.  I then went to
the parent directory (hobbit-4.1.2p1) and ran make, but it errored out with
error:2.  I checked the mod date on the hobbitgraph.cgi file and it was
still set to the date that I originally compiled the program.  I am running
Hobbit on FC4.  Any suggestions?

Thanks,

Dave

Hmmm.  All I can think of is that I made the changes in the original tree that I installed hobbit from, just a few weeks ago.  I'd already done all the configuration steps and installed a working hobbit server from that tree, then went back and made the graph changes, then re-ran make.

Were you working from a just-unpacked hobbit tree??  That might account for your problem.  Other than that, I don't know why it would be different.  I'm working from 4.1.2p1 too.

wrong.  I created a hobbit account and ran the installation configure and
make as hobbit, make install under su.  But I have been logging in as root
on the system so that I could edit the config files and scripts.  Maybe that
is why the make failed?  I was working from the same tree.

That's possible.  You might have a file now owned by root that make can't update.  Personally, I created the hobbit userid, went through the entire installation process as root, then set up a startup script that su's to hobbit to start the server.
