Morning there are some good practices how to enable snmpv3.
1. SNMP v3 is standard feature set of the SNMP packages in all main *Nix distros.
2. on your device enable snmp v3 and set variables: username, password , crypto key. (username and password are mandatory) 
3. on your network device choose type of the encryption for password (MD5/SHA) for encryption key (DES/AES/AES-128). 
Since you set minimall requirements you can verify if the configuration is correct via snmpwalk.
check manual: https://linux.die.net/man/1/snmpwalk

t-shoot snmp output if don`t receive correct reply from device

============================

Now is the time to add device to Observium:
- add new device and fill username and password and encryption type to the form.

You should read some materials about snmpv3 is more complex than snmpv2. 
I fully recommend: https://en.wikipedia.org/wiki/Simple_Network_Management_Protocol

Let us know if works or not for you.

Additionally not every linux distribution supports full featured SNMPv3 security.

 

For Debian please have a closer look at https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=972985

This is a kind reminder,

 

What I’m looking for are the steps to communicate via SNMPv3 from Observium.

 

The endpoint’s already configured to enable the SNMPv3

Hi,

 

SNMPv3 is more complex than SNMPv2 and requires all of the configuration parameters to match.

 

If you're having trouble making SNMPv3 work to a particular type of device, you should try to make it work properly from the commandline using snmpwalk first.

 

We can't really give a great deal of help for end devices beyond auth and encryption configuration on both Observium and the end device needing to match.

 

adam.

Hello Observium team,

 

 

 

I enabled SNMPV3 in my HP switch, but the Observium shows me error in the verification process and unable to add this device!

 

 

 

Can you please support?

 

 

 

Best regards
