This field needs to replace /opt/datadog-agent/agent/checks.d/apache.py

Run the following script to fix an apache instance

curl https://gist.github.com/philliphaines/06e7cef908f921de94b5/raw/9c0674f973ae6e49bdf0c5d32ef43fd5c0feb30b/gistfile1.py > /opt/datadog-agent/agent/checks.d/apache.py
sudo /etc/init.d/datadog-agent restart

is this solution still current? im having problem with datadog-agent cant find the pem file although the file is there
