### Docker image build
|
|
|
|
Run the following command from the root of VictoriaMetrics repository in order to build `victoriametrics/vmui` Docker image:
|
|
|
|
```
|
|
make vmui-release
|
|
```
|
|
|
|
Then run the built image with:
|
|
|
|
```
|
|
docker run --rm --name vmui -p 8080:8080 victoriametrics/vmui
|
|
```
|
|
|
|
Then navigate to `http://localhost:8080` in order to see the web UI.
|
|
|
|
|
|
### Static build
|
|
|
|
Run the following command from the root of VictoriaMetrics repository for building `vmui` static contents:
|
|
|
|
```
|
|
make vmui-build
|
|
```
|
|
|
|
The built static contents is put into `app/vmui/packages/vmui/` directory.
|
|
|
|
|
|
### Updating vmui embedded into VictoriaMetrics
|
|
|
|
Run the following command from the root of VictoriaMetrics repository for updating `vmui` embedded into VictoriaMetrics:
|
|
|
|
```
|
|
make vmui-update
|
|
```
|
|
|
|
This command should update `vmui` static files at `app/vmselect/vmui` directory. Commit changes to these files if needed.
|
|
|
|
Then build VictoriaMetrics with the following command:
|
|
|
|
```
|
|
make victoria-metrics
|
|
```
|
|
|
|
Then run the built binary with the following command:
|
|
|
|
```
|
|
bin/victoria-metrics -selfScrapeInterval=5s
|
|
```
|
|
|
|
Then navigate to `http://localhost:8428/vmui/`. See [these docs](https://docs.victoriametrics.com/#vmui) for more details.

## Predefined dashboards
|
|
|
|
vmui allows you to pre-define dashboards. <br/>
|
|
Predefined dashboards will be displayed in the `"Dashboards"` tab.
|
|
If there are no dashboards or if they cannot be fetched, the tab will be hidden.
|
|
|
|
### Setup
|
|
|
|
You can setup pre-defined dashboards in two ways: [Setup by local files](#setup-by-local-files) or [Setup by flag](#setup-by-flag)
|
|
|
|
#### Setup by local files
|
|
|
|
By creating local files in the "folder" directory:
|
|
|
|
- In this case, to update the dashboards, you need to recompile the binary;
|
|
- These dashboards will be displayed if there are no dashboards located at the path set by the "--vmui.customDashboardsPath" flag.
|
|
|
|
1. Create `.json` config file in a folder `app/vmui/packages/vmui/public/dashboards/`
|
|
2. Add the name of the created JSON file to `app/vmui/packages/vmui/public/dashboards/index.js`
|
|
|
|
#### Setup by flag
|
|
|
|
It is possible to define path to the predefined dashboards by setting `--vmui.customDashboardsPath`.
|
|
- The panels are updated when the web page is loaded;
|
|
- Only those dashboards that are located at the path specified by the `--vmui.customDashboardsPath` flag are displayed;
|
|
- Local files from the previous step are ignored.
|
|
|
|
1. Single Version
|
|
If you use single version of the VictoriaMetrics this flag should be provided for you execution file.
|
|
```
|
|
./victoria-metrics --vmui.customDashboardsPath=/path/to/your/dashboards
|
|
```
|
|
|
|
2. Cluster Version
|
|
If you use cluster version this flag should be defined for each `vmselect` component.
|
|
```
|
|
./vmselect -storageNode=:8418 --vmui.customDashboardsPath=/path/to/your/dashboards
|
|
```
|
|
At that moment all predefined dashboards files show be near each `vmselect`. For example
|
|
if you have 3 `vmselect` instances you should create 3 copy of your predefined dashboards.
|
|
|
|

## Timezone configuration
|
|
|
|
vmui's timezone setting offers flexibility in displaying time data. It can be set through a configuration flag and is adjustable within the vmui interface. This feature caters to various user preferences and time zones.
|
|
|
|
### Default Timezone Setting
|
|
|
|
#### Via Configuration Flag
|
|
|
|
- Set the default timezone using the `--vmui.defaultTimezone` flag.
|
|
- Accepts a valid IANA Time Zone string (e.g., `America/New_York`, `Europe/Berlin`, `Etc/GMT+3`).
|
|
- If the flag is unset or invalid, vmui defaults to the browser's local timezone.
|
|
|
|
#### User Interface Adjustments
|
|
|
|
- Users can change the timezone in the vmui interface.
|
|
- Any changed setting in the interface overrides the flag's default, persisting for the user.
|
|
- The timezone specified in the `--vmui.defaultTimezone` flag is included in the vmui's timezone selection dropdown, aiding user choice.
|
|
|
|
### Key Points
|
|
|
|
- **Fallback to Browser's Local Timezone**: If the flag is not set or an invalid timezone is specified, vmui uses the local timezone of the user's browser.
|
|
- **User Preference Priority**: User-selected timezones in vmui take precedence over the default set by the flag.
|
|
- **Cluster Consistency**: Ensure uniform timezone settings across cluster nodes, but individual user interface selections will always override these defaults.
|
|
|
|
### Examples
|
|
|
|
Setting a default timezone, with user options to change:
|
|
|
|
```
|
|
./victoria-metrics --vmui.defaultTimezone="America/New_York"
|
|
```
|
|
|
|
In this scenario, if a user in Berlin accesses vmui without changing settings, it will default to their browser's local timezone (CET). If they select a different timezone in vmui, this choice will override the `"America/New_York"` setting for that user.
