Thank you for reaching out to the Live Community. Please allow me to address your questions.
You can get the details from Endpoint Data collected by data Cortex XDR ensuring that you have XTH ad-on.

https://docs-cortex.paloaltonetworks.com/r/Cortex-XDR/Cortex-XDR-Pro-Administrator-Guide/Endpoint-Data-Collection

Else you can use below query as a baseline, please finetune it for ssh related logins:
dataset = xdr_data
| filter event_type = ENUM.LOGIN_EVENT
| join (
dataset = endpoints
| filter platform = ENUM.LINUX ) as endp endp.endpoint_name = agent_hostname
Please mark the response as "Accept as Solution" if it answers your query.

Hello ,

Thank you for your help !

Tried the query and this only gives us results for root login information is there a way to get non root login and the dst ip and port are also not seen even after modifying the query a bit.

Hello,

I will suggest to use below query as a baseline and modify the query as per your need.

preset = xdr_login_events | filter agent_hostname = "xxxxx"

Please mark the response as "Accept as Solution" if it answers your query.
