Troubleshooting No Graph for Service

[Patrick Nixon]

Hey all,
 Just wondering if anyone has suggestions on how to troubleshoot why a
files graph wouldn't be showing up, yet other hosts with similar
configurations are just fine.

 The variations are version of OS (RHEL3,4,5), paths that include dots
and don't, and if a single file vs a file/directory pair are being
monitored.

 I turned on debugging and extracted entries for one host (cdr-db)

rrd-status.log :

rrd-data.log:
no corresponding entries.

 Thanks for any insights.
