How to check memory usage

I’m not a Vera expert and have run into problems with one of my Veralites. Having read a lot of posts I am now very suspicious it is a memory utilisation issue. I would like to check memory utilisation and I read this in an old thread …

"Going in via SSH and running the free mem command will give you an idea of what you’ve got free. "

but I have no idea how to do this. Can somebody explain the process in more detail or point me in the right direction please.

If you run the AltUI plugin, then a simple one-liner in Lua Test will print you lots of info…

for line in io.lines "/proc/meminfo" do print(line) end

gives (on my Vera Edge)…

Or can install the system monitor plugin…

Here is a sample of the output of System Monitor:

Thank you everyone. I finally retrieved the data through installing system monitor. I figure from that if the veralite has 64 MB of RAM then memory capacity is not an issue as it shows 28310 Kb free memory. Back to waiting for a response from support :frowning:
