RPM Probes and data collection via SSH / netconf

Hi

Seems to be failing to scrape any data from the vMX router regarding RPM probes.

Can see messages in the logs that opennti is connecting on port 22 then nothing is happening, as a result the python script is seeing no returned data from the initial “show version”

Any ideas why its not seemingly logging in and running the commands properly?

Cheers! Jon.

Could very well been the lack of hostname.

Hi, Just to test… could you please add a hostname to the vmx? regards
