`yanic` is a respondd client that fetches, stores and publishes information about a Freifunk network. The goals:
* 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/)
* Provide a little webserver for a standalone installation with a meshviewer
## How it works
In the first step Yanic sends a multicast message to the group `ff05::2:1001` and port `1001`.
Recently seen nodes that does not reply are requested via a unicast message.
## Documentation
Take a look at the [git](https://github.com/FreifunkBremen/yanic/blob/main/SUMMARY.md) or [website](https://freifunkbremen.github.io/yanic/)
# Installation
Take a look into the Documentation (see above) or for Quick Overview in [INSTALL.md](INSTALL.md).
If you like Docker you may want to take a look [here](https://github.com/christf/docker-yanic).
## Configuration
Read comments in [config_example.toml](config_example.toml) for more information.
## Running
Yanic provides several commands:
### Usage
Run Yanic without any arguments to get the usage information:
```
Usage:
yanic [command]
Available Commands:
help Help about any command
import Imports global statistics from the given RRD files, requires InfluxDB
query Sends a query on the interface to the destination and waits for a response
serve Runs the yanic server
Flags:
-h, --help help for yanic
--loglevel uint32 Show log message starting at level (default 40)
--timestamps Enables timestamps for log output
Use "yanic [command] --help" for more information about a command.
```
#### Serve
Runs the yanic server
```
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
Global Flags:
--loglevel uint32 Show log message starting at level (default 40)
--timestamps Enables timestamps for log output
```
#### Query
Sends a query on the interface to the destination and waits for a response
```
Usage:
yanic query [flags]
Examples:
yanic query "eth0,wlan0" "fe80::eade:27ff:dead:beef"
Flags:
-h, --help help for query
--ip string ip address which is used for sending (optional - without definition used the link-local address)
--port int define a port to listen (if not set or set to 0 the kernel will use a random free port at its own)
--wait int Seconds to wait for a response (default 1)
Global Flags:
--loglevel uint32 Show log message starting at level (default 40)
--timestamps Enables timestamps for log output
```
#### Import
Imports global statistics from the given RRD files (ffmap-backend).
```
Usage:
yanic import [flags]
Examples:
yanic import --config /etc/yanic.toml olddata.rrd global global
Flags:
-c, --config string Path to configuration file (default "config.toml")
-h, --help help for import
Global Flags:
--loglevel uint32 Show log message starting at level (default 40)
--timestamps Enables timestamps for log output
```
