Cisco_telemetry_mdt input plugin not able to get source IP via tcp.

Telegraf

Hello Team,

Telegraf plugin as been deployed on our system and It has been connected and has been receiving data from several cisco devices using inputs.cisco_telemetry_mdt.

we are able to receive all telemetry related data in tags in a json formate except one key which is a critical key called the source IP.

Telegraf.conf

Telegraf sample output contains

“tags”:{“host”:“abcd”,“interface_name”:“XYZ0/0/0/0”,
“path”:“Cisco-IOS-XR-qos-ma-oper:qos/interface-table/interface/input/service-policy-names/service-policy-instance/statistics”,
“source”:“SourceDeviceName”,“subscription”:“subscription”},“timestamp”:12345678}

Not the Source IP.

After going through the code for cisco telemetry mdt. Unfortunaltely, I can’t find any line adding the source IP to the data point.

Could you please suggest a way to get the field source IP via the telegraf output.

Thank you.
Regards!

Hey!

Is the source IP information reported in the message sent to telegraf or are you referring to the sender of the message? In any case, it would be nice to have this in an issue… Can you please open one and let me know!?
If the message contains the address, please add a reference to the issue showing an example and/or the documentation of that message.

Best regards,

Sven
