+===== InfluxDB Setup =====
+**Installation**
+https://docs.influxdata.com/influxdb/v0.9/introduction/installation/
+**Authentication**
+Setup users in influx -cli:
+Admin:
+  CREATE USER admin WITH PASSWORD 'xxxxxxxxxxxx' WITH ALL PRIVILEGES
+Normal User for logging:
+  CREATE USER logger WITH PASSWORD 'yyyyyyyyyyyyyyyyyyyy'
+  GRANT ALL ON "stats" TO logger
+  GRANT ALL ON "_internal" TO logger
+  GRANT ALL ON "opentsdb" TO logger
+At last enable auth in /etc/influxdb/influxdb.conf  Config:
+  auth-enabled = true
+Restart influxdb and login to the cli via:
+  influx -username 'admin' -password 'xxxxxxxxxxxx'  -ssl -unsafeSsl
+**Setup Basic Auth in Grafana Datasources**
+https://docs.influxdata.com/influxdb/v0.9/administration/authentication_and_authorization/
+**httpS**
+With a self-signed Cert you get crypto, but no verification of the host. Anyway:
+  openssl req -x509 -nodes -newkey rsa:2048 -keyout /etc/ssl/influxdb-selfsigned.key -out /etc/ssl/influxdb-selfsigned.crt -days 99999
+/etc/influxdb/influxdb.conf :
+  https-enabled = true
+  https-certificate = "/etc/ssl/influxdb-selfsigned.crt"
+  https-private-key = "/etc/ssl/influxdb-selfsigned.key"
+Change the Datasource URLs in Grafana to use httpS and check "With CA Cert"
+https://docs.influxdata.com/influxdb/v1.2/administration/https_setup/#step-1-generate-a-self-signed-certificate
+===== Telegraf Setup =====
+Telegraf is a superb logging system with a loooot of plugins. It can write directly to influxdb via http(s)
+**Installation**
+With the InfluxDB repos you can install it directly via deb packages:
+https://docs.influxdata.com/telegraf/v0.13/introduction/installation/
+**Configuration**
+Setup InfluxDB Connection in /etc/telegraf/telegraf.conf:
+  [[outputs.influxdb]]
+     urls = ["http://192.168.1.1:8086"]
+     database = "stats"
+     username = "logger"
+     password = "yyyyyyyyyyyyyyyyyyyy"
+**httpS**
+Change the URLs to httpS://..
+For self-signed certs add:
+  insecure_skip_verify = true
