+# Add new database type

+**InsertNode** is stores statistics per node
+
+**InsertLink** is stores statistics per link
+
+**InsertGlobals** is stores global statistics (by `site_code`, and "global" like in `runtime.GLOBAL_SITE` overall sites).
+
+**PruneNodes** is prunes historical per-node data
+
+**Close** is called during shutdown of Yanic.
+
+
+
+For startup, you need to bind your database type by calling `database.RegisterAdapter("typeofdatabase",ConnectFunction)`
+
+it should be in the `func init() {}` of your package.
+
+
+
+The _typeofdatabase_ is used as mapping in the configuration `[[database.connection.typeofdatabase]]` the `map[string]interface{}` of the content are parsed to the _ConnectFunction_ and on of your implemented `Connection` or a `error` is needed as result.

+# Build and Installation
+
+## go
+
+### Install
+```sh
+cd /usr/local/
+wget https://storage.googleapis.com/golang/go1.9.1.linux-amd64.tar.gz -O go-release-linux-amd64.tar.gz
+tar xvf go-release-linux-amd64.tar.gz
+rm go-release-linux-amd64.tar.gz
+```
+
+### Configure go
+Add these lines in your root shell startup file (e.g. `/root/.bashrc`):
+
+```sh
+export GOPATH=/opt/go
+export PATH=$PATH:/usr/local/go/bin:$GOPATH/bin
+```
+
+## Yanic
+
+### Compile
+As root:
+```sh
+go get -v -u github.com/FreifunkBremen/yanic
+```
+
+### Install
+
+```sh
+cp /opt/go/src/github.com/FreifunkBremen/yanic/contrib/init/linux-systemd/yanic.service /lib/systemd/system/yanic.service
+systemctl daemon-reload
+```
+
+Before start, you should configurate yanic by the file `/etc/yanic.conf`:
+
+```
+systemctl start yanic
+```
+
+Enable to start on boot:
+
+```
+systemctl enable yanic
+```
+
+### Update
+For an update just stop yanic and then call the same `go` command again (again as root):
+```sh
+systemctl stop yanic
+go get -v -u github.com/FreifunkBremen/yanic
+```
+Then update the config file, for example look at the diff with the new example:
+```sh
+diff /opt/go/src/github.com/FreifunkBremen/yanic/config_example.toml /etc/yanic.conf
+```

+# Quick Configuration
+
+```sh
+cp /opt/go/src/github.com/FreifunkBremen/yanic/config_example.toml /etc/yanic.conf
+```
+
+# Quick configuration
+For an easy startup you only need to edit the `interfaces` in section
+`[respondd]` in file `/etc/yanic.conf`.  
+
+Then create the following files and folders:
+```sh
+adduser --system yanic --home /var/lib/yanic
+mkdir -p /var/lib/yanic
+mkdir -p /var/www/html/meshviewer/data
+touch /var/log/yanic.log
+chown yanic /var/log/yanic.log /var/lib/yanic /var/www/html/meshviewer/data
+```
+
+#### Standalone
+If you like to run a standalone meshviewer, just set `enable` in section
+`[webserver]` to `true`.
+
+##### Configure the [meshviewer](https://github.com/ffrgb/meshviewer):
+set `dataPath` in `config.json` to `/data/` and make the `build` directory
+accessible under `/var/www/html/meshviewer`.
+
+#### With webserver (Apache, nginx)
+The meshviewer needs the output files like `nodes_path` and `graph_path` inside
+the same directory as the `dataPath`. Change the path in the section
+`[meshviewer]` accordingly.

+# Usage
+
+Yanic provides several commands:
+
+* `import`
+* `query`
+* `serve`
+
+## Import
+
+### RRD-File
+Warning, just tested with olddata.rrd from Freifunk Bremen generated by detailed-rrds branch of [ffmap-backend](https://github.com/ffnord/ffmap-backend/tree/detailed-rrds)
+
+```
+Usage:
+  yanic import <file.rrd> [flags]
+
+Examples:
+  yanic import --config /etc/yanic.toml olddata.rrd
+
+Flags:
+  -c, --config string   Path to configuration file (default "config.toml")
+  -h, --help            help for import
+```
+
+### Firstseen
+To import firstseen values there is a little script in contrib:
+
+```
+/opt/go/src/github.com/FreifunkBremen/yanic/contrib/yanic-import-timestamp -n path/to/nodes_old.json -s state.json /var/lib/yanic/state.json
+```
+
+On a productive system @ once:
+
+```
+systemctl stop yanic; cp /var/lib/yanic/state.json /var/lib/yanic/state.bak; /opt/go/src/github.com/FreifunkBremen/yanic/contrib/yanic-import-timestamp -n path/to/nodes_old.json -s /var/lib/yanic/state.json; systemctl start yanic;
+```
+
+## Serve
+runs yanic in collector-modus to genereate files (e.g. for meshviewer) and save values in databases
+
+from shell
+
+```
+Usage:
+  yanic serve [flags]
+
+Examples:
+  yanic serve --config /etc/yanic.toml
+
+Flags:
+  -c, --config string   Path to configuration file (default "config.toml")
+  -h, --help            help for serve
+```
+
+or run as [daemon]({{site.baseurl}}/docs/install.html)
+
+
+## Query
+
+Send a single request and show response like `gluon-neighbour-info` on gluon.
+
+e.g.  to check the right interface
+
+```
+Usage:
+  yanic query <interface> <destination> [flags]
+
+Examples:
+  yanic query wlan0 "fe80::eade:27ff:dead:beef"
+
+Flags:
+  -h, --help       help for query
+      --wait int   Seconds to wait for a response (default 1)
+```

+# About
+
+A little overview of yanic in connection with other software:
+![Overview](overview.svg)
+
+## How respondd works
+
+It sends the `gluon-neighbour-info` request and collects the answers.
+
+It will send UDP packets with multicast group `ff02:0:0:0:0:0:2:1001` and port `1001`.
+
+If a node does not answer, it will request with the last know address under the port `1001`.

+* Generating JSON for [Meshviewer](https://github.com/ffrgb/meshviewer)
+* Storing statistics in [InfluxDB](https://influxdata.com/) or [Graphite](https://graphiteapp.org/) to be analyzed by [Grafana](http://grafana.org/)
