exometer_report_snmp oid_conflict error

[IgorKarymov]

Hi! I faced with this error when trying to create very basic example of using of exometer with snmp integration.

(agent@cabal)2> 17:20:30.877 [info] MIB /tmp/exometer/EXOMETER-METRICS-MIB unloaded

My example configuration:
https://github.com/IgorKarymov/exometer/tree/oid_conflict_error

Steps to reproduce:

• make

• make devnode_snmp_agent (note: start command and configuration file was changed by me)

  • exometer:update_or_create([api, opiwa1], 3000, histogram, [{snmp, []}])

  Also looks like, that changes of dynamically created MIB was stopped after this error occurred (you can introduce new metrics, but file still be the same, however calls will returns 'ok')

Could you please confirm or comment this issue?

I will try to reproduce this error and get back to you.

Your custom branch is missing the template you were using. Could you share that as well? I suspect something clashing within the template.

[IgorKarymov]

Thanks for response. I'm using this one https://github.com/IgorKarymov/exometer/blob/master/priv/EXOMETER-METRICS-MIB.mib

Hmm, with this file I can't reproduce the error. Will need to try with a properly cleaned copy then.
