CPU-Load > 100%

On some busy MSSQL Servers we often have a high CPU load which is displayed with values over 100%, as you see in the example here with
18,446,744,073,660,160,000% (wow
).
Why does this happen and is it possible to correct this display error so that only 100% is displayed at full load?

Hi
@sandro.isoletta, thanks for reaching out.
Which plugin/check command is giving you the crazy CPU load values?

Hi and thank you for your answer.
I've just took a look (nagios was not configured by me, I am new in this company). The command is:
/usr/lib/nagios/plugins/check_nt -H $HOSTADDRESS$ -s $USER6$ -v CPULOAD -l 15,90,99,60,70,85

The check_nt plugin used the NSClient++ agent that is running on the Windows system and it may be a bug wit the version that you are using and you should upgrade it.
You can find it here

Another cause is the counters need to be rebuilt on the Windows server.
