glances client for DD-WRT or other openwrt routers.

[Jeff Eberl]

Hey, just "discovered" glances (I'm a real Christopher Columbus here). I was hoping to get some stats from my router, and make them available to glances. I have a DD-WRT router, and optware installed, with python 2.7 installed.

Unfortunately, it doesn't do pip, and it won't be able to compile on the router.

Also, I can't see a way to install psutils.

So, I'm about to give up.

Is there a simple python only client that anyone knows about that I could run and publish some of the stuff that glances would use?

Even if it just had the CPU, Memory, and USB Stick free space, that would be a start.

Maybe I have to implement all of this: https://github.com/nicolargo/glances/wiki/The-Glances-2.x-API-How-to ?

This would also be useful on my arduino Yun, which uses a version of openwrt.

If i understand yours needs, you want to monitor your DD-WRT router and Arduino Yum (powered by OpenWRT) using Glances. I do not think that you can install Glances directly on your devices (because Glances uses PsUtil and PsUtil should be available in order to make Glances grab the system stats).

Another solution will be to use the Glances SNMP feature. Glances can grab stats through SNMP. You nee to install all the pre-requisites (latest Glances version and the PySNMP python lib).
The run Glances with the following command line:

# glances --snmp-force -c <ip>

Where <ip> is the IP address of your DD-WRT or Arduino.

Note: the SNMP feature is under development...

That seems like it should work. 

Any tips on debugging? I think I have the snmp working:

But a call to glances gives me a blank screen for a few moments, then exits without a word. (glances --snmp-force -c 10.0.2.1)

glances -V

Glances v2.5.1 with psutil v4.0.0

I'd imagine it's frustrating to get support questions on bleeding edge features, but I'd like to help. I don't have 40 hours/week to work on it, but I can find some time.

Strange...

Can you run Glances with the debug mode (-d) and pastebin us the /tmp/glances.log file ?

# glances -d --snmp-version 2c --snmp-force -c <ip>

Not sure where that CRITICAL is coming from. I did try snmpwalk'ing those codes, and got responses.
