Yes, I manually refreshed the test, too.Have you tried to refresh "SPU usage test"?
Did that, same effect: running the script on the agent machine returns "1.56", f.e., but hostmon shows 9, or 10.If you have installed mpstat utility on your system, you may try to change linux related string in cpu.sh with the following string:Code: Select all
Linux) mpstat -P ALL | tail -1 | awk '{print 100-$(NF-1)}';;
Code: Select all
Linux) mpstat -P ALL | grep all | awk '{print 100-$(NF-1)}';;
Code: Select all
Linux) mpstat -P ALL | tail -1 | awk '{print 100-$(NF-1)}';;
Sorry, I cannot see any reason why it shows such difference. Probably, you have to recompile the agent on your system. Please send request to support@ks-soft.net and we will send you the source codes.RicochetPeter wrote:Did that, same effect: running the script on the agent machine returns "1.56", f.e., but hostmon shows 9, or 10.
Actually, both these commands are equivalent and correct. You may use both of them.RicochetPeter wrote:Linux) mpstat -P ALL | grep all | awk '{print 100-$(NF-1)}';;

I don't think so. In a multi-CPU machine, the version with "grep" shows the mpstat summary for all CPUs, the version with "tail" shows the last CPU...Actually, both these commands are equivalent and correct.

In general, the syntax you offered is more correct. However, I have the following output on the multi-proc system:RicochetPeter wrote: I don't think so. In a multi-CPU machine, the version with "grep" shows the mpstat summary for all CPUs, the version with "tail" shows the last CPU...

Argh, that's correct, I haven't thought of that.Another thing is that "grep all" will not work on localized systems, where second string does not contain "all" word, but contains some localized characters.
Sorry, my fault. It really shows the last CPU on multi-CPU machine. You are right. So, you may use "grep all".RicochetPeter wrote:Sorry, it will only get the value for the last CPU, as far as I understand the "tail" programme.

Have you made changes in cpu.sh file? You should replace Linux related string using the following (please note: grep all in lowercase!):invisik wrote:HostMonitor reports like 95% utilization on a mostly idle system.

Linux) mpstat -P ALL | grep all | awk '{print 100-$(NF-1)}';;According to the output of mpstat utility you mentioned, average Idle time on your machine is 50.97 So, utilized time calculated as 100-50.97 = 49.03invisik wrote:I ran:

and the result is always 49.07, which also seems odd.
