 === To Do === === To Do ===
-  * /etc/collectd/collectd.conf correctly setted up? + 
-    * Server Plugin: check if "grafana.iqo.uni-hannover.de" with security level = "None" works for a database +  * if bind address already in use find PID with ''netstat -tulpn'' and kill process e.g. with ''sudo kill 1258'' 
-    * Python Plugin: Import modules? +  * types db file in /usr/local/share/collectd needs to be copied to server! otherwise influxd won't even start and listens to server forever
-  * influxd already running? port in use? (can't create database)+
