The persisted values can be queried from within openHAB. There also are nice tools on the web for visualizing InfluxDB time series, such as [Grafana](http://grafana.org/). > There are two Influxdb persistence bundles which support different InfluxDB versions. This service, named `influxdb`, supports InfluxDB 0.9 and newer, and the `influxdb08` service supports InfluxDB up to version 0.8.x. ## Database Structure The states of an item are persisted in time series with names equal to the name of the item. All values are stored in a field called "value" using integers or doubles, `OnOffType` and `OpenClosedType` values are stored using 0 or 1. The times for the entries are calculated by InfluxDB. An example entry for an item with the name "AmbientLight" would look like this: |time | sequence_number| value| |-----|-----------------|-------| |1402243200072 | 79370001 | 6| ## Prerequisites First of all you have to setup and run an InfluxDB server. This is very easy and you will find good documentation on it on the [InfluxDB web site](https://docs.influxdata.com/influxdb/v1.2/). Then database and the user must be created. This can be done using the InfluxDB admin web interface. If you want to use the defaults, then create a database called `openhab` and a user with write access on the database called `openhab`. Choose a password and remember it. ## Configuration This service can be configured in the file `services/influxdb.cfg`. | Property | Default | Required | Description | |----------|---------|:--------:|-------------| | url | http://127.0.0.1:8086 | No | database URL | | user | openhab | No | name of the database user, e.g. `openhab` | | password | | Yes | password of the database user that you chose in [Prerequisites](#prerequisites) above | | db | openhab | No | name of the database | | retentionPolicy | autogen | No | name of the retentionPolicy. Please note starting with InfluxDB >= 1.0, the default retention policy name is no longer `default` but `autogen`. | All item- and event-related configuration is defined in either the file `persistence/influxdb.persist`.
