# Metricator's API
|
|
|
|
This page describes Metricator's API.
|
|
|
|
## URL forming
|
|
|
|
API URLs are formed like: `/api/vX/TYPE/OTHER_DATA`, where:
|
|
|
|
* `vX` is a version (e.g. `v1`).
|
|
* `TYPE` - request type (see below).
|
|
* `OTHER_DATA` - other data that is needed to properly process request of `TYPE`.
|
|
|
|
## Versions
|
|
|
|
Metricator's API currently supports API version 1.
|
|
|
|
## Handlers
|
|
|
|
### Get Metricator's build info
|
|
|
|
**URL**: `/api/vX/info`
|
|
|
|
Returns a JSON with build info with following items:
|
|
|
|
* `Branch` for git branch.
|
|
* `Build` for commit **number**.
|
|
* `CommitHash` for git commit hash.
|
|
* `Version` for tagged (or not tagged) build.
|
|
|
|
Caveats:
|
|
|
|
1. `Version` contains string formed with [Semantic Versioning](https://semver.org/spec/v2.0.0.html) in mind, so there is either "X.Y.Z" for tagged release or "X.Y.Z-dev` for development (built not from tag) release.
|
|
|
|
Example:
|
|
|
|
```json
|
|
{"Branch":"master","Build":"24","CommitHash":"095e24a2b0b908d790153a4ed0bee51d9dba7685","Version":"0.1.0-dev"}
|
|
```
|
|
|
|
### Get registered applications list
|
|
|
|
**URL**: `/api/vX/apps_list`
|
|
|
|
Returns a JSON with all known applications.
|
|
|
|
Example:
|
|
|
|
```json
|
|
["app1", "app2", "gw1", "gw2"]
|
|
```
|
|
|
|
### Get all known metrics for application
|
|
|
|
**URL**: `/api/vX/metrics/APP_NAME`
|
|
|
|
Where:
|
|
|
|
* `APP_NAME` is a name of registered application.
|
|
|
|
Example:
|
|
|
|
```json
|
|
[
|
|
{
|
|
"Name":"dnsdist_frontend_tcpgaveup/frontend:127.0.0.1:53/proto:TCP/thread:0",
|
|
"Description":"Amount of TCP connections terminated after too many attempts to get a connection to the backend",
|
|
"Type":"counter",
|
|
"Value":"0",
|
|
"Params":null
|
|
},
|
|
{
|
|
"Name":"dnsdist_frontend_queries/frontend:127.0.0.1:53/proto:UDP/thread:0",
|
|
"Description":"Amount of queries received by this frontend",
|
|
"Type":"counter",
|
|
"Value":"0",
|
|
"Params":null
|
|
},
|
|
{
|
|
"Name":"dnsdist_frontend_queries/frontend:127.0.0.1:53/proto:UDP/thread:0",
|
|
"Description":"Amount of queries received by this frontend",
|
|
"Type":"counter",
|
|
"Value":"53842",
|
|
"Params":null,
|
|
}
|
|
]
|
|
```
|
|
|
|
### Get single metric data
|
|
|
|
**URL**: `/api/vX/metrics/APP_NAME/METRIC_NAME`
|
|
|
|
Where:
|
|
|
|
* `APP_NAME` is a name of registered application.
|
|
* `METRIC_NAME` is a name of metric exposed by this application.
