Add custom labels support in /targets endpoint #74
Description
To support custom labels and metrics collection intervals (scrape_interval) for different services, we would like to implement the ability to set
Example of the /targets endpoint:
[
{
"targets": ["X.X.X.X:9890/metrics?target=system:0"]
},
{
"targets": ["X.X.X.X:9890/metrics?target=service1"],
"labels": {
"datacenter": "dc1",
"__scrape_interval__": "5m",
"__scrape_timeout__": "2m",
"__no_stale_markers__": "true"
}
},
{
"targets": ["X.X.X.X:9890/metrics?target=service2"],
"labels": {
"datacenter": "dc2",
"__scrape_interval__": "2m",
"__scrape_timeout__": "5m",
"__no_stale_markers__": "true"
}
}
]
Example of config file:
services:
"service1":
service_type: "postgres"
conninfo: "postgres://postgres_exporter:XXXXX@Z.Z.Z.Z:5432/db1"
target_labels:
- name: __scrape_interval__
value: 5m
- name: __scrape_timeout__
value: 2m
- name: __no_stale_markers__
value: true
- name: datacenter
value: dc1
"service2":
service_type: "postgres"
conninfo: "postgres://postgres_exporter:XXXXX@Y.Y.Y.Y:5432/db2"
target_labels:
- name: __scrape_interval__
value: 2m
- name: __scrape_timeout__
value: 5m
- name: __no_stale_markers__
value: true
- name: datacenter
value: dc2
