# requiemdb
Permanent Storage for Open Telemetry Data.
# Features
- **OTLP gRPC server**: You can send metrics, traces and logs directly
from your apps using otel gRPC exporter. Works with all supported language SDK.
- **Query as code**: version, reuse , run or experiment with scripts.
- **Embedded javascript engine**: Use modern javascript or typescript for querying.
- **Standard compliant data**: Work with data as defined in Open Telemetry Standards
You don't need bespoke query language to understand and get insight from your
applications. Work with samples as defined in [Open Telemetry Protocol](https://github.com/open-telemetry/opentelemetry-proto) using modern javascript or typescript.
# Getting started
## Installation
You can see release page for downloads if you have go installed do this
```bash
go install github.com/gernest/requiemdb/cmd/rq@latest
```
This will have `rq` binary installed
## Start the server
```
rq
```
Wait for 2 minutes to have `rq` collect the process stats so we can query them.
> Metrics,traces and logs emitted by `rq` are stored in the same `rq` instance.
> This is to allow quick evaluation of `rq` capabilities before deployment.
Let's check system cpu time, create a file `cpu.ts`
```ts
// cpu.ts
import { Metrics } from "@requiemdb/rq";
/**
* Query instant system.cpu.time
*/
Metrics.render(
(new Metrics()).
name("system.cpu.time").
query()
)
```
```bash
rq query cpu.ts
```
```
system.cpu.time
TIMESTAMP VALUE ATTRIBUTES
2024-04-03 14:37:40 193h2m11.21s { state = "idle" }
2024-04-03 14:37:40 13h36m20.38s { state = "user" }
2024-04-03 14:37:40 8h20m8.09s { state = "system" }
2024-04-03 14:37:40 0s { state = "other" }
```
# Sending data
```
RQ_OTLP_LISTEN=localhost:4317 rq
```
Configure your gRPC exporter to use `RQ_OTLP_LISTEN` endpoint.
