Cole

Cole can use his sixth sense to give you metrics about your Grafana dashboards

Overview

Cole is a lightweight service that handles HTTP logs of Grafana to provide insights about the usage of Grafana instances and expose it through Prometheus metrics.

Grafana router logging dependency

Cole uses its sixth sense by Grafana HTTP logs, and because of this, you need to enable the router_logging to log all HTTP requests (not just errors).

For more information about router logging, please, check the Grafana official documentation.

Metrics Documentation

See the docs directory for more information on the exposed metrics.

Building from source

To build Cole from source code, first ensure that you have a working Go environment with version 1.16 or greater installed.

To build the source code you can use the make build, which will compile in the assets so that Cole can be run from anywhere:

$ mkdir -p $GOPATH/src/github.com/nicolastakashi/cole
$ cd $GOPATH/src/github.com/nicolastakashi/cole
$ git clone https://github.com/nicolastakashi/cole.git
$ cd cole
$ make build
$ ./cole server <args>

The Makefile provides several targets:

• build: build the cole
• fmt: format the source code
• vet: check the source code for common errors
• tests: run unit tests
