# InfluxDB (up to 0.8.x) Persistence
|
|
|
|
This service allows you to persist and query states using the [InfluxDB](http://influxdb.org) time series database. 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 `influxdb08`, supports InfluxDB up to version 0.8.x, and the `influxdb` service supports InfluxDB 0.9 and newer.
|
|
|
|
## 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|

## Prerequisites
|
|
|
|
First of all you have to setup and run an InfluxDB server up to version 0.8.x. This is very easy and you will find good documentation on it on the [InfluxDB web site](https://docs.influxdata.com/influxdb/v0.8/).
|
|
|
|
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/influxdb08.cfg`.
