Script using the Mist remote shell to access a Junos Device and retrieve the log entries (from /var/log/messages*) matching a specific string.

The Script is using the following Junos commands:

• file list /var/log/messages* to get the list of messages files
• file show {message_file} | match {log_match_string} | count on each file to get the number of entries (for validation purpose)
• file show {message_file} | match {log_match_string} | no-more on each file to get the entries (for validation purpose)

IMPORTANT NOTE

this script cannot be run on Windows (work in progress but may never happen)

Usage

• install the dependencies with python3 -m pip install -r requirements.txt
• configure the env file (default env file is ./.env, it's location can be changed in the script itself)
• run the script with python3 ./ws_remote_logs.py
• check the ws_remote_logs.txt to get the results, or ws_remote_logs.log to see the script and websocket logs
