I have installed OpManager (Build 8051) on RHEL 5 and attempting to monitor several pfsense embedded routers / firewalls.  The monitors (CPU Util, Memory Util, etc) are collecting data and graphing.  The Dials are not displaying any data and stating "No Data Available".  The monitor test are returning values and I have modified the opmanager_snapshot_dial.xml as per other directions found in this forum.

Just to confirm operation I added a Netscreen 5GT to OpManager and the dials do populate for it.

Is there an updated troubleshooting procedure for this problem?  

Thanks.
