# metric2fs-rs
|
||||
|
||||
A simple graphite metric metadata storage.
|
||||
|
||||
This is a POC.
|
||||
|
||||
## Features
|
||||
|
||||
Handle most, but not all, graphite paths style & wildcards listed on https://graphite.readthedocs.io/en/latest/render_api.html#paths-and-wildcards
|
||||
|
||||
* Asterisk globbing (eg: `test*`);
|
||||
* List & ranges (eg: `[a-z0-9]` or `[abc]`);
|
||||
* Value lists (eg: `{abc,def}`).
|
||||
|
||||
However, the double star globbing is not supported (eg: `**`).
|
||||
|
||||
|
||||
## Build & run
|
||||
|
||||
```sh
|
||||
cargo build
|
||||
RUST_LOG=debug cargo run
|
||||
```
|
||||
|
||||
## API
|
||||
|
||||
### Write a metric
|
||||
|
||||
Send a POST request to `/metric` with metric(s) in the body
|
||||
|
||||
```sh
|
||||
curl -sq -d testaroo.a.a.a http://localhost:3000/metric
|
||||
```
|
||||
|
||||
### Retrieve metrics
|
||||
|
||||
Send a GET request to `/metric` with `q=` parameter as a globbing expression
|
||||
|
||||
```sh
|
||||
curl "http://localhost:3000/metric?q=te*ar*.\{a\}.\{b,c\}.\[bcd\]"
|
||||
```
|
||||
|
||||
## Testing
|
||||
|
||||
```sh
|
||||
for metric in testaroo.{a,b,c}.{a,b,c}.{a,b,c,d,e,f}; do curl -sq -d $metric http://localhost:3000/metric ; done
|
||||
curl "http://localhost:3000/metric?q=te*ar*.\{a\}.\{b,c\}.\[b-e\]"
|
||||
testaroo.a.b.b
|
||||
testaroo.a.b.c
|
||||
testaroo.a.b.d
|
||||
testaroo.a.b.e
|
||||
testaroo.a.c.b
|
||||
testaroo.a.c.c
|
||||
testaroo.a.c.d
|
||||
testaroo.a.c.e
|
||||
```
