Description

Telemetry is not working as expected on the device. The device is establishing connection but tool doesn't seem to be able to collect information from the device.

Solution

Telemetry for junos cli is not supported on EX4300. Below is the document for reference:

https://apps.juniper.net/feature-explorer/feature/4332?fn=gRPC%20support%20for%20the%20Junos%20Telemetry%20Interface

We have confirmed it as we need to have the below processes to run Telemetry on Junos. We checked on different ex4300s. We saw the same results.

 

root@switch> start shell 

% cd /usr/sbin/

% ls -ltr agent*

ls: No match.

% ls -ltr na-grpcd

ls: na-grpcd: No such file or directory

% ls -ltr jsd

lrwxr-xr-x  1 root  wheel  30 Mar 26 09:33 jsd -> /packages/mnt/jsd/usr/sbin/jsd

% exit

exit

{master:0}

root@switch> show system processes | match na-grpcd 

{master:0}

root@switch> show system processes | match agentd 

{master:0}

 

It has also been tested on different software versions and the results are same.
