After you've [installed InfluxDB OSS](/influxdb/v2.1/install/), you're ready to get started. Explore the following ways to work with your data:
|
|
|
|
- [Collect and write data](#collect-and-write-data)
|
|
- [Query data](#query-data)
|
|
- [Process data](#process-data)
|
|
- [Visualize data](#visualize-data)
|
|
- [Monitor and alert](#monitor-and-alert)
|
|
|
|
*Note:** To run InfluxDB, start the `influxd` daemon ([InfluxDB service](/influxdb/v2.1/reference/cli/influxd/)) using the [InfluxDB command line interface](/influxdb/v2.1/reference/cli/influx/). Once you've started the `influxd` daemon, use `localhost:8086` to log in to your InfluxDB instance.
|
|
|
|
To start InfluxDB, do the following:
|
|
1. Open a terminal.
|
|
2. Type `influxd` in the command line.
|
|
|
|
```sh
|
|
influxd
|
|
```
|
|
|
|
### Collect and write data
|
|
|
|
Collect and write data to InfluxDB using the Telegraf plugins, the InfluxDB v2 API, the `influx` command line interface (CLI), the InfluxDB UI (the user interface for InfluxDB 2.1), or the InfluxDB v2 API client libraries.
|
|
|
|
#### Use Telegraf
|
|
|
|
Use Telegraf to quickly write data to {{< cloud-name >}}.
|
|
Create new Telegraf configurations automatically in the InfluxDB UI, or manually update an existing Telegraf configuration to send data to your {{< cloud-name "short" >}} instance.
|
|
|
|
For details, see [Automatically configure Telegraf](/influxdb/v2.1/write-data/no-code/use-telegraf/auto-config/)
|
|
and [Manually update Telegraf configurations](/influxdb/v2.1/write-data/no-code/use-telegraf/manual-config/).
|
|
|
|
#### Scrape data
|
|
|
|
**InfluxDB OSS** lets you scrape Prometheus-formatted metrics from HTTP endpoints. For details, see [Scrape data](/influxdb/v2.1/write-data/no-code/scrape-data/).
|
|
|
|
#### API, CLI, and client libraries
|
|
|
|
For information about using the InfluxDB v2 API, `influx` CLI, and client libraries to write data, see [Write data to InfluxDB](/influxdb/v2.1/write-data/).
|
|
|
|
### Query data
|
|
|
|
Query data using Flux, the UI, and the `influx` command line interface.
|
|
See [Query data](/influxdb/v2.1/query-data/).
|
|
|
|
### Process data
|
|
|
|
Use InfluxDB tasks to process and downsample data. See [Process data](/influxdb/v2.1/process-data/).
|
|
|
|
### Visualize data
|
|
|
|
Build custom dashboards to visualize your data.
|
|
See [Visualize data](/influxdb/v2.1/visualize-data/).
|
|
|
|
### Monitor and alert
|
|
|
|
Monitor your data and sends alerts based on specified logic.
|
|
See [Monitor and alert](/influxdb/v2.1/monitor-alert/).
