I installed beta 4 today and snmp stopped working on a number of devices that are being monitored. Is this a known issue?

I think I answered my own question. Apparently there are now SNMP profiles and I since I don't use standard snmp community names it convert over into beta4 from beta3. If I create a profile using my non-standard names and apply that profile to the devices, it works. Interesting.

oh.. just discovered that ALL the custom data sources have to be manually changed to the correct SNMP profile. What a pain.

Yep. same here. Also, all my notifications just stop working, except syslog and mail. For some reason that I dont know, the sound, beep, flash and popup just do nothing. When I click the "test" button on each notification, there comes a "Ok" and nothing else. Anyone can confirm this?

Another thing Im looking is if there are problems with scan. When a network range is being scanned, in particular a specific device that have about 500 pppoe interfaces. Well, seems that every time dude scan the pppoe device, looks like when I run a complete snmp walk on that device. I dont need to retrieve all snmp info from that device at once. Im not sure yet about what is periodically running on dude that suddenly jump the dude server bit rate from 90kbps to about 800kbps. When disable the network scan, this stop happening. I also have "two" builtin scan tools which seems not working and do nothing. Everything else seems fine, including fixes.

The most wanted thing "for me" stand still: dude server graphing using funtions, not only snmp OIDs. Thx

For your convenience you can select multiple objects (data sources), right
click, choose settings and modify multiple objects at the same time.
(pressing ok or apply updates them all)

beep/popup/flash/sound notifications will be fixed in next version,

When dude is scanning network it is not doing full snmp walk, but it needs to get arp, ip, routes and interface tables. If you have many entries in those
tables then it takes a lot of traffic. I suggest you increase scanning interval.

Scan tool is in development.

Thanks for the reports.
