SSH Commands To Check The VPS Performance

Here are some common SSH commands done through putty to check the performance of the VPS

Checking the processor used for the VPS

 [abc@vps2 ~]$ cat /proc/cpuinfo
processor       : 0
vendor_id       : GenuineIntel
cpu family      : 6
model           : 44
model name      : Intel(R) Core(TM) i7 CPU 970  @ 3.20GHz
stepping        : 2
cpu MHz         : 3200.539
cache size      : 12288 KB

To check the I/O (Input Output ratio) of the VPS

[abc@vps2 ~]$ dd if=/dev/zero of=test bs=64k count=16k conv=fdatasync
16384+0 records in
16384+0 records out
1073741824 bytes (1.1 GB) copied, 24.9287 s, 43.1 MB/s
[abc@vps2 ~]$

To check the download speed of the VPS

[abc@vps2 ~]$ wget cachefly.cachefly.net/100mb.test

[abc@vps2 ~]$

To check Disk space on the VPS

To check in KB

[abc@vps2 ~]$ df
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/simfs            26214400  11343856  14870544  44% /
none                     65536         4     65532   1% /dev
tmpfs                    65536       396     65140   1% /tmp
tmpfs                    65536       396     65140   1% /tmp
[abc@vps2 ~]$

To check in GB

[abc@vps2 ~]$ df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/simfs             25G   11G   15G  44% /
none                   64M  4.0K   64M   1% /dev
tmpfs                  64M  396K   64M   1% /tmp
tmpfs                  64M  396K   64M   1% /tmp
[abc@vps2 ~]$

An automated to do some of this is to use the shell script “Linux server info script” at akamaras.
