This is my first post. I want to make one perl agent which calculate following things from Linux Server. Actually I want to pull all this information from 2 linux client and wants to display on web interface.
First I want to calculate below details
1) CPU
2) MEMORY
3) Physical Server or Virtual Server Detail (Server Type)
I want to do this in perl.
I found below code which is helpful
Code:
use Sys::CPU;
$number_of_cpus = Sys::CPU::cpu_count();
printf("I have %d CPU's\n",$number_of_cpus);
print " Speed : ",Sys::CPU::cpu_clock(),"\n";
print " Type : ",Sys::CPU::cpu_type(),"\n";
Now i want help about Memory and Physical or Virtual Server checking.
Hi,
Is there a command I can use to find out how many CPU's and what type are on my server? (I was told to use cat /proc/cpuinfo)
Also, how do I know what kind of bus speeds are on my server?
Thanks in advance:) (3 Replies)

im runing top in batch mode like this
top -b -n1 > somefile
but the cpu usage info is not correct.
if i run top normally, the first second, i see the same wrong info, and then it corrects itself.
i found only one small mention of it on this forum. with this link... (7 Replies)
