localhost;CPU load;predict_load15,load15,load5,load1
localhost;CPU utilization;predict_util,util,wait,system,user

.

The predictive metrics in my example are:

Code Block
languagebash
themeRDark
predict_load15
predict_util

.

Now let's grep for the livestatus queries. In this example, I want to check the "predict_load15":

I receive one query for every entry of the prediction:

Let's execute one query to check the result:

Last but not least, please check this directory:

Code Block
languagebash

./var/check_mk/prediction/<HOSTNAME>/

.

The prediction will create for every Host and Service a directory with the metrics as a subdirectory:
