Title: Clarification about Memory and CPU
Post by: paros on February 01, 2017, 04:41:26 am
Can someone give advice how I should understand the values from Eventwatcher (what is normal/not normal)?
For example, I have a Vera Plus and have the following values:

Vera Memory
Red line: 150MB
Blue line: 195

EventWatcher Memory
0.41MB

Vera CPU
30%

In Unix terms, available = free + cached, so you have lots of elbow room.

The time to worry is when free suddenly dips low.

My Veras (Lite and Edge) typically run at 20% CPU, but I'm not using any heavy plugins like PLEG.

Would it be a good idea to write a short explanation on the reports?

Quote from: EventWatcher User Guide, p. 5
The blue area in the memory plot shows 'cached' memory, the red is 'free', the total being the 'available' memory.  If the free memory falls towards zero then the Luup process is liable to restart itself.

...agreed that's not the same as on the report itself.
