Unable to poll the SNMP configuration of the SA devices with second username

Issue/Introduction

The Security Analytics software can be polled by SNMP.  There is an option to configure a second read-only username.  This is not done correctly by the UI when saved. This can be fixed by logging in as root and editing the configuration file manually.

Environment

Release : 8.2.6

Cause

The SNMP configuration allows for a second read-only username but does not update the /etc/snmpd.conf file properly with that username. This will need to be done from the command line as root.

Resolution

The steps to add a second read-only username:

1. Login as root using ssh
2. Edit /etc/snmp/snmpd.conf
3. Find the section that looks like:

#       groupName      securityModel securityName
group   notConfigGroup usm           firstsnmpusername

     4. Add the second user with a line like this:

group   notConfigGroup usm           secondrouser

     5. The end result will look like:

#       groupName      securityModel securityName
group   notConfigGroup usm           firstsnmprousername
group   notConfigGroup usm           secondrousername

    6. Save the file
    7. Restart snmpd with systemctl restart snmpd

You should be able to poll snmp on the sensor with the second user.
