# Grafterm [![CircleCI][circleci-image]][circleci-url] [![Go Report Card][go-reportcard-image]][go-reportcard-url]
Visualize metrics dashboards on the terminal, like a simplified and minimalist version of [Grafana] for terminal.
## Features
- Multiple widgets (graph, singlestat, gauge).
- Multiple datasources usage.
- User stored datasources.
- Override dashboard datasource ID to different datasource ID configured by the user.
- Custom dashboards based on JSON configuration files.
- Extensible metrics datasource implementation (Prometheus and Graphite included).
- Templating of variables.
- Auto time interval adjustment for queries.
- Auto unit formatting on widgets.
- Fixed and adaptive grid.
- Color customization on widgets.
- Configurable autorefresh.
- Single binary and easy usage/deployment.
## Installation
Download the binaries from [releases]
## Running options
Exit with `q` or `Esc`
### Simple
```bash
grafterm -c ./mydashboard.json
```
### Relative time
```bash
grafterm -c ./mydashboard.json -d 48h
```
### Refresh interval
```bash
grafterm -c ./mydashboard.json -r 2s
```
### Debugging
When grafterm doesn't show anything may be that has errors getting metrics or similar. There is available a `--debug` flag that will write a log on `grafterm.log` (this path can be override with `--log-path` flag)
Read the log
```bash
tail -f ./grafterm.log
```
And run grafterm in debug mode.
```bash
grafterm -c ./mydashboard.json -d 48h -r 2s --debug
```
### Fixed time
Setting a fixed time range to visualize the metrics using duration notation. In this example is start at `now-22h` and end at `now-20h`
```bash
grafterm -c ./mydashboard.json -s 22h -e 20h
```
Setting a fixed time range to visualize the metrics using timestamp [ISO 8601] notation.
```bash
grafterm -c ./mydashboard.json -s 2019-05-12T12:32:11+02:00 -e 2019-05-12T12:35:11+02:00
```
### Replacing dashboard variables
```bash
grafterm -c ./mydashboard.json -v env=prod -v job=envoy
```
### Replacing dashboard datasource configuration
Replace dashbaord `prometheus` datasource with user datasource `thanos-prometheus` (check [Datasources](#datasources) section):
```bash
grafterm -c ./mydashboard.json -a "prometheus=thanos-prometheus"
```
Replace dashboard `prometheus` datasource with user datasource `thanos-prometheus` available on `/tmp/my-datasources.json` user datasource configuration file:
```bash
grafterm -c ./mydashboard.json -a "prometheus=thanos-prometheus" -u /tmp/my-datasources.json
```
## Dashboard
Check [this][cfg-md] section that explains how a dashboard is configured. Also check [dashboard examples][dashboard-examples]
## Datasources
Datasources are the way grafterm knows how to retrieve the metrics for the dashboard.
check available types and how to configure in [this][cfg-md] section.
**If you want support for a new datasource type, open an issue or send a PR**
### Overriding dashboard datasources
Dashboard referenced datasources on the queries can be override.
#### User datasource
Grafterm dashboards can have default datasources but the user can override these datasources using a datasources config file. This file has the same format as the dashboard configuration file but will ignore anything other than the `datasources` block. Example:
```json
{
"version": "v1",
"datasources": {
"prometheus": {
"prometheus": { "address": "http://127.0.0.1:9090" }
},
"localprom": {
"prometheus": { "address": "http://127.0.0.1:9091" }
},
"thanos": {
"prometheus": { "address": "http://127.0.0.1:9092" }
},
"m3db": {
"prometheus": { "address": "http://127.0.0.1:9093" }
},
"victoriametrics": {
"prometheus": { "address": "http://127.0.0.1:8428" }
},
"wikimedia": {
"graphite": { "address": "https://graphite.wikimedia.org" }
}
}
}
```
