## Installation
|
|
|
|
Installing VictoriaLogs datasource
|
|
[requires](https://grafana.com/docs/grafana/latest/setup-grafana/configure-grafana/#allow_loading_unsigned_plugins)
|
|
the following changes to Grafana's `grafana.ini` config:
|
|
|
|
``` ini
|
|
[plugins]
|
|
allow_loading_unsigned_plugins = victorialogs-datasource
|
|
```
|
|
|
|
If using `grafana-operator`, adjust `config` section in your `kind=Grafana` resource as below:
|
|
|
|
```
|
|
config:
|
|

|
### Grafana Provisioning
|
|
|
|
Provisioning of Grafana plugin requires creating [datasource config file](http://docs.grafana.org/administration/provisioning/#datasources):
|
|
|
|
```yaml
|
|
apiVersion: 1
|
|
datasources:
|
|
# <string, required> Name of the VictoriaLogs datasource
|
|
# displayed in Grafana panels and queries.
|
|
- name: VictoriaLogs
|
|
# <string, required> Sets the data source type.
|
|
type: victorialogs-datasource
|
|
# <string, required> Sets the access mode, either
|
|
# proxy or direct (Server or Browser in the UI).
|
|
access: proxy
|
|
# <string> Sets URL for sending queries to VictoriaLogs server.
|
|
# see https://docs.victoriametrics.com/victorialogs/querying/
|
|
url: http://victorialogs:9428
|
|
# <string> Sets the pre-selected datasource for new panels.
|
|
# You can set only one default data source per organization.
|
|
isDefault: true
|
|
```
|
|
|
|
Please find the example of provisioning Grafana instance with VictoriaLogs datasource below:
|
|
|
|
1. Create a file at `./provisioning/datasources/vm.yml` with datasource example file.
|
|
|
|
1. Define Grafana installation via docker-compose:
|
|
|
|
```yaml
|
|
version: '3.0'
|
|
services:
|
|
grafana:
|
|
image: grafana/grafana:11.0.0
|
|
environment:
|
|
- GF_INSTALL_PLUGINS=https://github.com/VictoriaMetrics/victorialogs-datasource/releases/download/v0.2.1/victorialogs-datasource-v0.2.1.zip;victorialogs-datasource
|
|
- GF_PLUGINS_ALLOW_LOADING_UNSIGNED_PLUGINS=victorialogs-datasource
|
|
ports:
|
|
- 3000:3000/tcp
|
|
volumes:
|
|
- ./provisioning:/etc/grafana/provisioning
|
|
```
|
|
|
|
1. Run docker-compose file:
|
|
|
|
```
|
|
docker-compose -f docker-compose.yaml up
|
|
```
|
|
|
|
After Grafana starts successfully, datasource should be available in the datasources tab
|

### Install in Kubernetes
|
|
|
|
#### Grafana helm chart
|
|
|
|
Example with Grafana [helm chart](https://github.com/grafana/helm-charts/blob/main/charts/grafana/README.md):
|
|
|
|
Option 1. Using Grafana provisioning:
|
|
|
|
``` yaml
|
|
env:
|
|
GF_INSTALL_PLUGINS: "https://github.com/VictoriaMetrics/victorialogs-datasource/releases/download/v0.2.1/victorialogs-datasource-v0.2.1.zip;victorialogs-datasource"
|
|
GF_PLUGINS_ALLOW_LOADING_UNSIGNED_PLUGINS: "victorialogs-datasource"
|
|
```
|
|
|
|
Option 2. Using Grafana plugins section in `values.yaml`:
|
|
|
|
``` yaml
|
|
plugins:
|
|
- https://github.com/VictoriaMetrics/victorialogs-datasource/releases/download/v0.2.1/victorialogs-datasource-v0.2.1.zip;victorialogs-datasource
|
|
```
|
|
|
|
Option 3. Using init container:
|
|
|
|
``` yaml
|
|
extraInitContainers:
|
|
- name: "load-vm-ds-plugin"
|
|
image: "curlimages/curl:7.85.0"
|
|
command: [ "/bin/sh" ]
|
|
workingDir: "/var/lib/grafana"
|
|
securityContext:
|
|
runAsUser: 472
|
|
runAsNonRoot: true
|
|
runAsGroup: 472
|
|
args:
|
|
- "-c"
|
|
- |
|
|
set -ex
|
|
mkdir -p /var/lib/grafana/plugins/
|
|
ver=$(curl -s -L https://api.github.com/repos/VictoriaMetrics/victorialogs-datasource/releases/latest | grep -oE 'v[0-9]+\.[0-9]+\.[0-9]+' | head -1)
|
|
curl -L https://github.com/VictoriaMetrics/victorialogs-datasource/releases/download/$ver/victorialogs-datasource-$ver.tar.gz -o /var/lib/grafana/plugins/vl-plugin.tar.gz
|
|
tar -xf /var/lib/grafana/plugins/vl-plugin.tar.gz -C /var/lib/grafana/plugins/
|
|
rm /var/lib/grafana/plugins/vl-plugin.tar.gz
|
|
volumeMounts:
|
|
# For grafana-operator users, change `name: storage` to `name: grafana-data`
|
|
- name: storage
|
|
mountPath: /var/lib/grafana
|
|
```
|
|
|
|
For `grafana-operator` users, the above configuration should be done for the part `/spec/deployment/spec/template/spec/initContainers` of your `kind=Grafana` resource.
|
|
|
|
This example uses init container to download and install plugin. To allow Grafana using this container as a sidecar set the following config:
|
|
|
|
```yaml
|
|
sidecar:
|
|
datasources:
|
|
initDatasources: true
|
|
enabled: true
|
|
```
|
|
|
|
See more about chart settings [here](https://github.com/grafana/helm-charts/blob/541d97051de87a309362e02d08741ffc868cfcd6/charts/grafana/values.yaml)
|
|
|
|
Option 4 would be to build custom Grafana image with plugin based on same installation instructions.
|
|
|
|
#### Grafana operator
|
|
|
|
Example with Grafana [operator](https://github.com/grafana-operator/grafana-operator):
|
|

|
|
curl -L https://github.com/VictoriaMetrics/victorialogs-datasource/releases/download/$ver/victorialogs-datasource-$ver.tar.gz -o /var/lib/grafana/plugins/vl-plugin.tar.gz
|
|
tar -xf /var/lib/grafana/plugins/vl-plugin.tar.gz -C /var/lib/grafana/plugins/
|
|
rm /var/lib/grafana/plugins/vl-plugin.tar.gz
|
|
volumeMounts:
|
|
- name: grafana-data
|
|
mountPath: /var/lib/grafana
|
|
config:
|
|
plugins:
|
|
allow_loading_unsigned_plugins: victorialogs-datasource
|
|
```
|
|
|
|
See [Grafana operator reference](https://grafana-operator.github.io/grafana-operator/docs/grafana/) to find more about Grafana operator.
|
|
This example uses init container to download and install plugin.
|
|
|
|

rm /var/lib/grafana/plugins/vl-plugin.tar.gz
|
|
```
|
|
|
|
1. Restart Grafana
|
|
|
|
## Getting started development
|
|
|
|
### 1. Configure Grafana
|
|
|
|
Installing dev version of Grafana plugin requires to change `grafana.ini` config to allow loading unsigned plugins:
|
|
|
|
``` ini
|
|
# Directory where Grafana will automatically scan and look for plugins
|
|
plugins = {{path to directory with plugin}}
|
|
```
|
|
|
|
``` ini
|
|
[plugins]
|
|
allow_loading_unsigned_plugins = victorialogs-datasource
|
|
```
|
|
|
|
### 2. Run the plugin
|
|
|
|
In the project directory, you can run:
|
|
|
|
```sh
|
|
# install dependencies
|
|
yarn install
|
|
|
|
# run the app in the development mode
|
|
yarn dev
|
|
|
|
# build the plugin for production to the `victorialogs-datasource` folder and zip build
|
|
yarn build:zip
|
|
```
|
|
|
|
### 3. How to build backend plugin
|
|
|
|
From the root folder of the project run the following command:
|
|
|
|
```
|
|
make victorialogs-backend-plugin-build
|
|
```
|
|
|
|
This command will build executable multi-platform files to the `victorialogs-datasource` folder for the following platforms:
|
|
|
|
* linux/amd64
|
|
* linux/arm64
|
|
* linux/arm
|
|
* linux/386
|
|
* amd64
|
|
* arm64
|
|
* windows
|
|
|
|
### 4.How to build frontend plugin
|
|
|
|
From the root folder of the project run the following command:
|
|
|
|
```
|
|
make victorialogs-frontend-plugin-build
|
|
```
|
|
|
|
This command will build all frontend app into `victorialogs-datasource` folder.
|
|
|
|
### 5. How to build frontend and backend parts of the plugin:
|
|
|
|
When frontend and backend parts of the plugin is required, run the following command from the root folder of the project:
|
|
|
|
```
|
|
make victorialogs-datasource-plugin-build
|
|
```
|
|
|
|
This command will build frontend part and backend part or the plugin and locate both parts into `victorialogs-datasource` folder.
|
|
|
|
## How to make new release
|
|
|
|
1. Make sure there are no open security issues.
|
|
1. Create a release tag:
|
|
* `git tag -s v1.xx.y` in `master` branch
|
|
1. Run `TAG=v1.xx.y make build-release` to build and package binaries in `*.tar.gz` release archives.
|
|
1. Run `git push origin v1.xx.y` to push the tag created `v1.xx.y` at step 2 to public GitHub repository
|
|
1. Go to <https://github.com/VictoriaMetrics/victorialogs-datasource/releases> and verify that draft release with the name `TAG` has been created and this release contains all the needed binaries and checksums.
|
|
1. Remove the `draft` checkbox for the `TAG` release and manually publish it.
|
|
|
|
## Notes
|
|
|
|
In the `plugin.json` file of our plugin, the `metrics` field is set to `true`. This is not to support metric queries in the classical sense but to ensure our plugin can be selected in the Grafana panel editor.
|
|
|
|
For more information on the fields in `plugin.json`, please refer to the [Grafana documentation](https://grafana.com/developers/plugin-tools/reference-plugin-json#properties).
