# Configuration
Here you would find a long description, maybe the description in [example file](https://github.com/FreifunkBremen/yanic/blob/master/config_example.toml) are enough for you.
The config file for Yanic written in "Tom's Obvious, Minimal Language." [syntax](https://github.com/toml-lang/toml).
(if you need somethink multiple times, checkout out the [[array of table]] section)
## [respondd]
{% method %}
Group for configuration of respondd request.
{% sample lang="toml" %}
```toml
[respondd]
enable = true
# synchronize = "1m"
collect_interval = "1m"
#[respondd.sites.example]
#domains = ["city"]
[[respondd.interfaces]]
ifname = "br-ffhb"
#ip_address = "fe80::..."
#send_no_request = false
#multicast_address = "ff02::2:1001"
#port = 10001
```
{% endmethod %}
### enable
{% method %}
Enable request and collection of data per respondd requests
{% sample lang="toml" %}
```toml
enable = true
```
{% endmethod %}
### synchronize
{% method %}
Delay startup until a multiple of the period since zero time
{% sample lang="toml" %}
```toml
synchronize = "1m"
```
{% endmethod %}
### collect_interval
{% method %}
How often send request per respondd.
It will send UDP packets with multicast address `ff02::2:1001` and port `1001`.
If a node does not answer after the half time, it will request with the last know address under the port `1001`.
{% sample lang="toml" %}
```toml
collect_interval = "1m"
```
{% endmethod %}
### [respondd.sites.example]
{% method %}
Tables of sites to save stats for (not exists for global only).
Here is the site _ffhb_.
{% sample lang="toml" %}
```toml
[respondd.sites.ffhb]
domains = ["city"]
```
{% endmethod %}
#### domains
{% method %}
list of domains on this site to save stats for (empty for global only)
{% sample lang="toml" %}
```toml
domains = ["city"]
```
{% endmethod %}
### [[respondd.interfaces]]
{% method %}
Interface that has an ip address in your mesh network.
It is possible to have multiple interfaces, just add this group again with new parameters (see toml [[array of table]]).
{% sample lang="toml" %}
```toml
[[respondd.interfaces]]
ifname = "br-ffhb"
#ip_address = "fe80::..."
#send_no_request = false
#multicast_address = "ff02::2:1001"
#port = 10001
```
{% endmethod %}
### ifname
{% method %}
name of interface on which this collector is running.
{% sample lang="toml" %}
```toml
ifname = "br-ffhb"
```
{% endmethod %}
### ip_address
{% method %}
ip address is the own address which is used for sending.
If not set or set with empty string it will take an address of ifname.
(If `multicast_address` is not set the link local address otherwise a global unicast address)
{% sample lang="toml" %}
```toml
ip_address = "fe80::..."
```
{% endmethod %}
### send_no_request
{% method %}
Disable sending multicast respondd request.
For receiving only respondd packages e.g. database respondd.
{% sample lang="toml" %}
```toml
send_no_request = true
```
{% endmethod %}
### multicast_address
{% method %}
Multicast address to destination of respondd.
If not set or set with empty string it will take the batman default multicast address `ff02::2:1001`
(Needed in babel for a mesh-network wide routeable multicast addreess `ff05::2:1001`)
{% sample lang="toml" %}
```toml
multicast_address = "ff02::2:1001"
```
{% endmethod %}
### port
{% method %}
Define a port to listen and send the respondd packages.
If not set or set to 0 the kernel will use a random free port at its own.
{% sample lang="toml" %}
```toml
port = 10001
```
{% endmethod %}

For all database types the is a internal job, which reset data for nodes (global statistics are still stored).
_(We have for privacy policy to store node data for maximum seven days.)_
{% sample lang="toml" %}
```toml
delete_after = "7d"
delete_interval = "1h"
```
{% endmethod %}

Every database type has his own configuration under `database.connection`.
It is possible to have multiple connections for one type of database, just add this group again with new parameters (see toml [[array of table]]).
{% sample lang="toml" %}
```toml
[[database.connection.example]]
enable = true
```
{% endmethod %}
### enable
{% method %}
Each database-connection has its own config block and needs to be enabled by adding:
{% sample lang="toml" %}
```toml
enable = true
```
{% endmethod %}
## [[database.connection.influxdb]]

Save collected data to InfluxDB.
There are would be the following measurements:
- node: store node specific data i.e. clients memory, airtime
- global: store global data, i.e. count of clients and nodes
- firmware: store the count of nodes tagged with firmware
- model: store the count of nodes tagged with hardware model
{% sample lang="toml" %}
```toml
enable = false
address = "http://localhost:8086"
database = "ffhb"
username = ""
password = ""
insecure_skip_verify = false
[database.connection.influxdb.tags]
tagname1 = "tagvalue 1"
system = "productive"
site = "ffhb"
```
{% endmethod %}
### address
{% method %}
Address to connect on InfluxDB server.
{% sample lang="toml" %}
```toml
address = "http://localhost:8086"
```
{% endmethod %}

{% sample lang="toml" %}
```toml
password = ""
```
{% endmethod %}
### insecure_skip_verify
{% method %}
Skip insecure verify for self-signed certificates.
{% sample lang="toml" %}
```toml
insecure_skip_verify = true
```
{% endmethod %}
### [database.connection.influxdb.tags]
{% method %}
You could set manuelle tags with inserting into a influxdb.
Useful if you want to identify the yanic instance when you use multiple own on the same influxdb (e.g. multisites).
Warning:
Tags used by Yanic would override the tags from this config (e.g. `nodeid`, `hostname`, `owner`, `model`, `firmware_base`, `firmware_release`, `frequency11g`, `frequency11a`).
{% sample lang="toml" %}
```toml
tagname1 = "tagvalue 1s"
# some useful e.g.:
system = "productive"
site = "ffhb"
```
{% endmethod %}
## [[database.connection.graphite]]
{% method %}
Save collected data to a graphite database.
{% sample lang="toml" %}
```toml

```
{% endmethod %}
### address
{% method %}
Address to connect on graphite server.
{% sample lang="toml" %}
```toml
address = "localhost:2003"
```
{% endmethod %}
### prefix
{% method %}
Graphite is replacing every "." in the metric name with a slash "/" and uses
that for the file system hierarchy it generates. it is recommended to at least
move the metrics out of the root namespace (that would be the empty prefix).
If you only intend to run one community and only freifunk on your graphite node
then the prefix can be set to anything (including the empty string) since you
probably wont care much about "polluting" the namespace.
{% sample lang="toml" %}
```toml
prefix = "freifunk"
```
{% endmethod %}
## [[database.connection.respondd]]
{% method %}
Forward collected respondd package to a address
(e.g. to another respondd collector like a central yanic instance or hopglass)

enable = false
type = "udp6"
address = "stats.bremen.freifunk.net:11001"
```
{% endmethod %}
### type
{% method %}
Type of network to create a connection.
Known networks are "tcp", "tcp4" (IPv4-only), "tcp6" (IPv6-only), "udp", "udp4" (IPv4-only), "udp6" (IPv6-only), "ip", "ip4" (IPv4-only), "ip6" (IPv6-only), "unix", "unixgram" and "unixpacket".
{% sample lang="toml" %}

```
{% endmethod %}
### address
{% method %}
Destination address to connect/send respondd package.
{% sample lang="toml" %}

address = "stats.bremen.freifunk.net:11001"
```
{% endmethod %}
## [[database.connection.logging]]
{% method %}
This database type is just for, debugging without a real database connection.
A example for other developers for new database types.
{% sample lang="toml" %}
```toml
enable = false
path = "/var/log/yanic.log"
```
{% endmethod %}
### path
{% method %}
Path to file where to store some examples with every line.
{% sample lang="toml" %}
