An object store can be used as data storage location for metrics, and logs which
|
|
can then be leveraged for systems observability.
|
|
|
|
## Metrics
|
|
|
|
### Prometheus
|
|
|
|
Prometheus itself has no object store capabilities, however two projects exist
|
|
which support storing metrics in an object store:
|
|
|
|
- [Cortex](https://cortexmetrics.io/)
|
|
- [Thanos](https://thanos.io/)
|
|
|
|
## System logs
|
|
|
|
### Vector
|
|
|
|
[Vector](https://vector.dev/) natively supports S3 as a
|
|
[data sink](https://vector.dev/docs/reference/configuration/sinks/aws_s3/)
|
|
(and [source](https://vector.dev/docs/reference/configuration/sources/aws_s3/)).
|
|
|
|
This can be configured with Garage with the following:
|
|
|
|
```bash
|
|
garage key new --name vector-system-logs
|
|
garage bucket create system-logs
|
|
garage bucket allow system-logs --read --write --key vector-system-logs
|
|
```
|
|
|
|
The `vector.toml` can then be configured as follows:
|
|
|
|
```toml
|
|
[sources.journald]
|
|
type = "journald"
|
|
current_boot_only = true
|
|
|
|
[sinks.out]
|
|
encoding.codec = "json"
|
|
type = "aws_s3"
|
|
inputs = [ "journald" ]
|
|
bucket = "system-logs"
|
|
key_prefix = "%F/"
|
|
compression = "none"
|
|
region = "garage"
|
|
endpoint = "https://my-garage-instance.mydomain.tld"
|
|
auth.access_key_id = ""
|
|
auth.secret_access_key = ""
|
|
```
|
|
|
|
This is an example configuration - please refer to the Vector documentation for
|
|
all configuration and transformation possibilities. Also note that Garage
|
|
performs its own compression, so this should be disabled in Vector.
