i am running into an space issue on my 64 bit Ubuntu running on Virtual machine even though the space available is 40 GB and total file system usage is 9.5 GB it shows me total usage 37 GB where is my remaining space being used ?
By getting Memtotal and Memfree values from "/proc/meminfo" and subtracting them we must get the Used Memory in Linux. Most of threads and web pages that I have visited have guided through this approach to compute the Total Memory Usage in Linux. But by implementing this method, I get different results with GNOME System Monitor! My result is greater than that (approximately double).
You know that we can use the command top to monitor the real-time CPU usage and toggle the result display to the per-processor view by pressing key '1'. The disadvantage of it is you can only monitor either the whole CPU usage or each processor usage. That is, you can't see them simultaneously. Does anyone know this?
Is there any way to calculate the Linux network interfaces RX , TX for all times?
The suggested method mentioned in this Cyberciti article titled: Linux See Ethernet Statistics only returns the stats of the machine currently, from the the time the system booted until now.
