API Error when running with 'Report SNMP performance data'

[luratech]

I'm getting these errors when i try to run the check with -P switch:

error: walk: unknown object ID (HOST-RESOURCES-MIB)
error: walk: unknown object ID (IF-MIB)
CRITICAL: API error occured: {u'message': u'Fewer items found in D-Bus signature than in Python arguments'}

snmp-settings should be correct - they work just fine in cacti-checks.
Any idea?

Hi,
On what version of NexentaStor is this happening? I can't reproduce this issue.
Also, when you login to your cacti server and run the check manually from that server does this still happen?

regards,

Brenn

Appliance version is 4.0.1 and it also happens on manual checks.
Been digging through the code - i'm almost sure it's not a problem with the script but some internal problem in Nexenta 4.0.1 - the message originates from /usr/lib/python2.6/vendor-packages/_dbus_bindings.so.

Hm, it actually does NOT look like Nexenta related:

tested it with a fresh nexenta 4.0.4 install and no customization except of snmp community.
Same results as on 4.0.1 - nmv.log:

I've also tested from different client machines without any differences.
