So I also upgraded to the latest and got the autodiscovery on custom OIDs.

Didn't have the best effect on my system as it mapped hundreds of individual Isilon nodes to a long range of custom OIDs I had created.

So lessons learned / feature requests :

Previously one could pick (one by one or multi select) the devices to be covered in a specific custom OID. THis option seems to have gone now. I'd like that option back, or alternatively be able to somehow filter or group devices. I also use the combined line or stack graphs for certain things and sometime need to show just a group of devices and not all. Right now with the new version I can only show either a single device or all devices as I cannot create custom OID groups and then narrow down what devices to show there.
On systems like Isilon where you may want to both have cluster wide data (so polling the cluster alias) but also monitor each node in the cluster, the lack of the above mentioned filtering/grouping is a problem as currently the custom OID will only work for me if I delete all individual nodes and only monitor the cluster alias.

On the other hand, now Servertech Sentry4 devices are better supported, so the net outcome of the upgrade was still positive for me.
