Type: improvement
Counters are labeled with interface indices in the Prometheus exporter
output. For example:
# TYPE _if_drops counter
_if_drops{thread="0",interface="0"} 0
_if_drops{thread="0",interface="1"} 0
_if_drops{thread="0",interface="2"} 2112
[..]
Currently, it's unable to map interface indices to the interface names
using only output provided by the Prometheus exporter. However, this
mapping is present in the vpp_get_stats output:
# vpp_get_stats dump /if/names
[0]: local0 /if/names
[1]: GigabitEthernet0/8/0 /if/names
[2]: GigabitEthernet0/9/0 /if/names
[..]
With this change, add name vectors to Prometheus exporter output as info
metrics. Thus exposing interfaces and their indices:
# TYPE _if_names_info gauge
_if_names_info{index="0",name="local0"} 1
_if_names_info{index="1",name="GigabitEthernet0/8/0"} 1
_if_names_info{index="2",name="GigabitEthernet0/9/0"} 1
