@jszwedko - Is this feature still under consideration ???

[jszwedko]

Hi @mkharibalaji !

It is still something we'd like to do, but isn't on our roadmap at the moment. We would be happy to help guide an external contribution for this though!

Hi @jszwedko ,
Happy to contribute.Is there any documentation on how to contribute and some info on writing source & sink.

[jszwedko]

Hi @mkharibalaji !

We are planning to write up some specific documentation for contributing new integrations soon (as well as reference implementations). In absence of that, my recommendation would be to:

• Copy a similar source, in this case the prometheus_scrape source might be the closest as a starting point since it also scrapes an external endpoint on an interval.
• See some of the development documentation which has general recommendations: https://github.com/vectordotdev/vector/blob/master/docs/CONTRIBUTING.md and https://github.com/vectordotdev/vector/blob/master/docs/DEVELOPING.md

Happy to answer any questions! I'm not terribly familiar with SNMP, but looking at Telegraf's configuration for it (https://www.influxdata.com/integration/snmp/) there seem to be a lot of options. I'd suggest starting with a minimal implementation that satisfies your use case and then we can extend it later (e.g. by adding support for encryption).

Thanks @jszwedko .Will check it out.

Lack of SNMP is the main reason for me Vector can't be considered as a replacement for Telegraf at the moment.

In the same scope, it would be great to have a SNMP Trap source. Currently, you have to run e.g. snmptrapd and have it convert your traps to syslog messages, which can then be ingested by the syslog source.
