Howdy,

I need some help pointing me in the right direction for troubleshooting.

I migrated Observium from Ubuntu to Debian and life is good except for smokeping.  I have no graphs but…
 * smokeping is installed
 * smokeping and observium’s config.php are using the same configuration as the old server
 * going to [host]cgi-bin/smokeping.cgi shows me all the graphs and they are up to date
 * going to the tech support page shows me that observium finds the graphs e.g.

- Found file ending in ".rrd": router_thorodin_rmham.rrd
- Determined to be a local file, for target router_thorodin_rmham
- After replacing configured split_char _ by . target is router.thorodin.rmham

so at this point I know smokeping is working, the graphs have the right perms to displayed (currently  smokeping:observium), and observium can see the rrd file.   Unfortunately going to the page I get the dreaded “Error drawing graph”.

At the bottom of the smokeping section in tech support I see two items. One is an error for no outgoing latency graph. Any ideas on what else I could look at?
RRD for incoming latency found.
RRD for outgoing latency not found.
