+
+ 
+## Custom telegraf plugins
+
+
+See https://github.com/influxdata/telegraf to learn about plugins.
+
+Useful plugins in this context are probably
+[exec](https://github.com/influxdata/telegraf/tree/1.5.1/plugins/inputs/exec)
+or
+[httpjson](https://github.com/influxdata/telegraf/tree/1.5.1/plugins/inputs/httpjson).
+
+Telegraf will save in the `telegraf` database from the embedded influxdb server.
+
+
+## Grafana
+
+You'll have to add yourself the influxdb data source in grafana, using the
+parameters published by the slapos instance.
+
+http://docs.grafana.org/features/datasources/influxdb/
+
+When adding datasource, use *proxy* option, otherwise Grafana makes your
+browser query influxdb directly, which also uses a self signed certificate.
+One workaround is to configure your browser to also accept influxdb certificate
+before using grafana, but using proxy seems easier.
+
+## Influxdb
+
+Influxdb backups are not done automatically by this software release.
+
+One important thing to notice is that the backup protocol is enabled on ipv4
+provided by slapos, so make sure this ip is not reachable from untrusted
+sources.
+
+## TODO
+
+* influxdb and telegraf runs with very low priority, this could become an option
+* make one partition for each service and use switch software type
+* make it easier to add custom configuration (how ?)
