Under certain architectures the memory and CPU values observed from the CLI only reflect the busy and idle values for the VM containing Junos, however under this VM there are different values, this article will expose a general review for them.
-Hypervisor performance monitoring
-Chassis values monitoring
From CLI go to shell(this under root user)
start shell
Then go to Host Shell
hshell
To check on RAM values:
-sh-4.1# dmidecode | grep 8192
Maximum Memory Module Size: 8192 MB
Installed Size: 8192 MB (Single-bank Connection)
Enabled Size: 8192 MB (Single-bank Connection)
Size: 8192 MB
-sh-4.1# dmidecode | grep "Installed Size"
Installed Size: Not Installed
Installed Size: 32 kB
Installed Size: 256 kB
Installed Size: 3072 kB
To check on CPU values:
-sh-4.1# dmidecode | grep Core
Family: Core i7
Core Count: 2
Core Enabled: 2
Multi-Core
To check on SSD values:
-sh-4.1#-sh-4.1# smartctl -a /dev/sda
smartctl 5.42 2011-10-20 r3458 [x86_64-linux-2.6.32-279.22.1.el6.x86_64]
