@Aresndiz The data in Splunk is the data being sent by that machine. What tells you that the data in Splunk is not the same as the data on the server? Splunk wil not change the data coming from your server.
I note that the table and the event list do not appear to have the same information, e.g. CPU instance 13 has a reading of 9.32 in your table, yet that number does not match any of the event data you show. Is this what you mean?
CPU measurements are sometimes difficult to compare - in your example, you show data from a 16 core CPU with individual cores ranging from 7 to 60% and a total of 15%. What is the sampling rate of your readings being sent to Splunk, as that reading represents the average value since the previous reading.
If you use a different sampling interval when looking at data on your server you may well see different values, so you need to be comparing like with like.
