Thomas,
Anyway while the shared memory is not working, you'll posiblehave trouble.
Did you already follow the verification of IPC/Shared memoryverification? Is not, take a look at one described by Henrik is at
http://www.hswn.dk/hobbiton/2005/10/msg00200.html
IPC also has a dedicated session on the install manual(http://www.hswn.dk/hobbit/help/install.html)
Hope this helps.-wm

so something else is wrong.

... are these not the rrd logs you meant..? Can't really find any others... also, if it's that, why is only one host affected?

Hmm.
Well, there are two webservers; one is showing apache graphs, the other isn't. Went ahead and added 'em to a (pretty aggressive) rotation schedule; rrd-data.log is 600k, rrd-status was about 3.5M. Just in case, rrd-status is now limited to 1M.
Stopped and restarted the server, but no apparent effect. The server that had its Apache graphs still does, and that one that doesn't, doesn't.
Here are some recent rrd log entries, if that sheds any light. "Mo" is the server with the graphs, "ws-1" is the one without:

Not sure what's going on here.

Hi Rob,
I dont know if this can help you but every time I have had problems with missing graphs its been because the rrd logfiles were too big.
Just a info..

Hello,
There are two webservers being monitored by hobbit (among many other different servers). Both have bb-hosts entries that are nearly identical. Both have the same version of the client on them (4.1.2p1). Both seem to be working perfectly well in all other respects - both internal (CPU, disk etc) and external (conn, http) tests seem to be working, and have graphs.
However on one, the apache trends show up as expected, and on the other, they have stopped graphing. Current values for the graphless one are good ol' "nan," but *just* for the 4 apache trend graphs - Utilization, Workers, CPU Ut and RPS.
All other trend graphs are there.
Historical data for before the sudden loss of graphing is there (i.e., about a week ago the graphing stopped - 12 day graph shows data before this cutoff).
Nothing has changed, been added, or modified as far as i can tell.
What am i missing..?
Thanks!
