Hi there,
a happy new year to all of you!
We’ve solved the issue… or I should say: we’ve found a dirty workaround…
After testing several long passwords for authPriv with/without special characters, lower/upper letters, with/without digits and so on, the SNMP v3 requests still failed with timeouts. Even a restart of the UPS or installing the latest firmware didn’t help.
In the end, we’ve changed the SNMP v3 settings to no authentication (noAuthNoPriv) - and it works in Checkmk.
Unfortunately, there are no hints in the HP documentation about password restrictions, so that we will have to live with this workaround.
Hope this helps other users with similar problems on that hardware.
Kind regards,
Antje
