## prometheus-mikrotik

tl;dr - prometheus exporter for mikrotik devices

This is still a work in progress .. consider `master` at the moment as a preview
release.

#### Description

A Prometheus Exporter for Mikrotik devices. Can be configured to collect metrics
from a single device or multiple devices. Single device monitoring can be configured
all on the command line. Multiple devices require a configuration file. A user will
be required that has read-only access to the device configuration via the API.

Currently the exporter collects metrics for interfaces and system resources. Others
can be added as long as published via the API.

#### Mikrotik Config

Create a user on the device that has API and read-only access.

`/user group add name=prometheus policy=api,read,winbox`

If `lte` is enabled it requires also the `test` policy.

`/user group add name=prometheus policy=api,read,winbox,test`

Create the user to access the API via.

`/user add name=prometheus group=prometheus password=changeme`

#### Single Device

`./mikrotik-exporter -address 10.10.0.1 -device my_router -password changeme -user prometheus`

where `address` is the address of your router. `device` is the label name for the device
in the metrics output to prometheus. The `user` and `password` are the ones you
created for the exporter to use to access the API.

User and password flags can be set with the `MIKROTIK_USER` and `MIKROTIK_PASSWORD` environment variables, respectively.

```
MIKROTIK_USER=prometheus
MIKROTIK_PASSWORD=changeme
./mikrotik-exporter -address 10.10.0.1 -device my_router
```

#### Config File

`./mikrotik-exporter -config-file config.yml`

where `config-file` is the path to a config file in YAML format.

###### example config
```yaml
devices:
  - name: my_router
    address: 10.10.0.1
    user: prometheus
    password: changeme
  - name: my_second_router
    address: 10.10.0.2
    port: 8999
    user: prometheus2
    password: password_to_second_router
  - name: routers_srv_dns
    srv:
      record: _mikrotik._udp.example.com
    user: prometheus
    password: password_to_all_dns_routers
  - name: routers_srv_custom_dns
    srv:
      record: _mikrotik2._udp.example.com
      dns:
        address: 1.1.1.1
        port: 53
    user: prometheus
    password: password_to_all_dns_routers

features:
  bgp: true
  dhcp: true
  dhcpv6: true
  dhcpl: true
  routes: true
  pools: true
  optics: true
```

If you add a devices with the `srv` parameter instead of `address` the exporter will perform a DNS query
to obtain the SRV record and discover the devices dynamically. Also, you can specify a DNS server to use
on the query.
