How to obtain output in a text file on Linux machine for commands executed on remote host over SSH?

How to obtain output in a text file on Linux machine locally for commands executed on remote host over SSH ?

• For example I SSH a remote host: ssh admin@10.0.0.1


• Provide Password: admin@IP 10.0.0.1's password: xxxx


• Now I give command to get the logs: show eventlog

Now I want to capture and save the output of this command in a text file and store that file on my local Linux machine manually or through a script.
Also if I want to get the output from multiple devices what should be the process ?
