bird_exporter
Metric exporter for bird routing daemon to use with Prometheus
Remarks
Since bird_exporter uses the bird unix sockets, bird has to be installed on the same maschine as bird_exporter. Also the user executing bird_exporter must have permission to access the bird socket files.
Bird configuration
To get meaningful uptime information bird has to be configured this way:
timeformat protocol iso long;
Important information for users of bird 2.0+
Version 2.0 of bird routing daemon does support IPv4 and IPv6 in one single daemon now.
For further information see here.
Since version 1.1 bird_exporter can be used with bird 2.0+ using the -bird.v2 parameter.
When using this parameter bird_exporter queries the same bird socket for IPv4 and IPv6.
In this mode the IP protocol is determined by the channel information and parameters -bird.ipv4, -bird.ipv6 and -bird.socket6 are ignored.
Metric formats
In version 1.0 a new metric format was introduced.
To prevent a breaking change the new format is optional and can be enabled by using the -format.new flag.
The new format handles protocols more generic and allows a better query structure.
Also it adheres more to the metric naming best practices.
In both formats protocol specific metrics are prefixed with the protocol name (e.g. OSPF running metric).
This is a short example of the different formats:
old format
bgp4_session_prefix_count_import{name="bgp1"} 600000
bgp6_session_prefix_count_import{name="bgp1"} 50000
ospfv3_running{name="ospf1"} 1
new format
bird_protocol_prefix_import_count{name="bgp1",proto="BGP",ip_version="4"} 600000
bird_protocol_prefix_import_count{name="bgp1",proto="BGP",ip_version="6"} 50000
bird_ospfv3_running{name="ospf1"} 1
Default Port
In version 0.7.1 the default port changed to 9324 since port 9200 is the default port of elasticsearch. The new port is now registered in the default port allocation list (https://github.com/prometheus/prometheus/wiki/Default-port-allocations)
Sockets
In version 0.8 communication to bird changed to sockets. The default socket path is /var/run/bird.ctl (for bird) and /var/run/bird6.ctl (for bird6). In case you are using different paths in your installation, the socket path can be specified by usind the -bird.socket (for bird) and -bird.socket6 (for bird6) flag.
