unmarshal errors

[jennykim...@gmail.com]

Hi!

I'm trying to run this tutorial (https://www.percona.com/blog/2016/02/29/graphing-mysql-performance-with-prometheus-and-grafana/) to get MySQL to work with Prometheus, but can't get my Prometheus to work. The config is written underneath and so is the error-message. Please help me!!!

I even tried the code in http://www.yamllint.com, and it said it was valid....

Thank you! :) 

cat << EOF > /opt/prometheus/prometheus.yml

Hi Jenny,

It appears you have accidentally included the 'cat' command in your config file. 

You'll want to remove the top and bottom lines from your config file (prometheus.yml) in order for it to work.
