Hopefully this is OK to post, but I’ve been tinkering with the idea of a script that could pull a bunch of information from an Alta Labs device, kinda like a support tool that some other vendors use to gather information to send to support. Although it’s mostly an information and log gathering tool at this point since I’m not much of a scripter!

Figured it was put together enough to post and see if it would help anyone or anyone else felt like tinkering with it. There’s probably some redundent commands or commands that pull excess information at this point but I didn’t feel like removing anything quite yet.

Credit to richb-hanover over here for the original script that I’ve just been tinkering with: [GitHub - richb-hanover/OpenWrtScripts: A set of scripts for maintaining and testing OpenWrt](https://github.com/richb-hanover/OpenWrtScripts?tab=readme-ov-file#getstatssh)

There’s some instructions in the script itself on putting it together, but generally I’ve done the following:

- Open the terminal
- Navigate to the cfg diretory `cd /cfg` since this will allow it to persist through reboots and things
- Run `cat > getstats.sh`
- Paste the contents of the script
- Press `Ctrl + D` a couple of times
- Run the script with `sh getstats.sh`
- Then it should spit out the file `/tmp/openwrtstats.txt` that can be further examined

And here’s the contents of the script itself plus an example of some of it’s output

```auto
#! /bin/sh
#
# getstats.sh - Collect diagnostic information about OpenWrt
# Write the data to a file (usually /tmp/openwrtstats.txt)
#
# Usage: sh getstats.sh ["command 1 to be executed" "command 2" "command 3" ...]
#
# *****To install and run this script*****
#
# SSH into your router and execute these statements. 
# 
# ssh root@192.168.1.1
# cd /tmp
# cat > getstats.sh 
# [paste in the contents of this file, then hit ^D]
# sh getstats.sh
# The results listed are written to the designated file
# (usually /tmp/openwrtstats.txt, unless redirected)

And now some of that example output, although quite abreviated since I was hitting the character limit 😅

Appending to my post here, it sounds like running `cat /cfg/config.json` might be a decent way to pulling a devices configuration to share if needed:

> [@Can' make IPSec VPN or Wireguard work anymore since several updates ago](https://forum.alta.inc/t/can-make-ipsec-vpn-or-wireguard-work-anymore-since-several-updates-ago/6085/5):
>
> It looks like charon is not running at all, which usually indicates that a VPN server is not configured. Can you grab the output of “cfg”, and send your (redacted) /cfg/config.json file via DM?

Copying the output into something like Visual Studio Code worked as a decent way to format the JSON into something more readable. Hopefully that proves helpful to someone somewhere down the line 🙂
