>**Note:**
* Telegraf 1.9.x is required to use the https:// option with Telegraf.
* Currently, not all plugins are supported.
* If you are already have a Telegraf agent running, you can use v. 1.8 or later and add the InfluxDB v2 output plugin to "dual land" data into your existing InfluxDB 1.x and InfluxDB 2.0 instances.

Follow the steps described here to quickly configure Telegraf plugins and to start collecting system metrics from your InfluxDB 2.0 OSS instance.
## Configure a connection for available Telegraf plugins
Follow the steps below to configure your Telegraf plugins and connection for
collecting system statistics.
1. Open a web browser to your InfluxDB 2.0 instance [localhost:9999](http://localhost:9999).
The login screen for the UI (user interface) appears.
2. Log in using your username and password. The **Getting started with InfluxDB 2.0** screen appears.
3. Click **Configure a Data Collector**. A new dialog appears with the **Telegraf** selected.
4. Click **Create Configuration**. The **Data Loading** page appears.
5. Select your predefined **Bucket**, click the **System** option, and then
click **Continue**. A page with **Plugins to Configure** appears.
6. Review the list of **Plugins to Configure**. Click **Continue** repeatedly to cycle through
information on each of the plugins and then continue to the next step. Alternatively, click
**Skip to Verify** to proceed to the next step.
7. On the **Listen for Telegraf Data** page, follow the steps to install Telegraf,
configure your API Token, and start Telegraf on your local instance.
8. Verify that you correctly completed these steps by clicking **Listen for Data** (if you don't
see this, scroll down the internal frame). A "Connection Found!" message appears.
9. After verifying your new connection, click **Finish**. Your configuration name
and the associated bucket name appears in the list of Telegraf connections.
After configuring your Telegraf plugins and connection, you can create a dashboard
that displays your system statistics.
## Create a dashboard to display system statistics
The steps below will guide you to creating a dashboard and adding a cell that
displays a system measurement that your InfluxDB 2.0 server instance is now collecting.
1. Click **Dashboards** in the navigation bar on the left. You should see the
**Dashboards** page that lists any existing dashboards.
2. Click **Create Dashboard**. A new dashboard appears.
3. Click **Name this Dashboard** and enter a name (for example, "System Stats").
4. Click **Add Cell**. A new page appears to define a cell to appear in your
new dashboard.
5. Click **Name this Cell** and enter a cell name (for example, "Maximum CPU Usage").
6. In the lower left, select the bucket that is collecting your system statistics.
Under **_measurement**, a listing of available measurements appears.
7. Click **cpu**. A new **_field** listing appears.
8. Scroll down the list and select **usage_system**. A new **cpu** listing appears.
9. In the **cpu** listing, select **cpu-total**.
10. In the **AGGREGATE FUNCTIONS** listing on the right, select **max**.
11. Click **Submit**, located above **AGGREGATE FUNCTIONS**. A line graph displaying
recently collected data appears.
12. To finish adding the cell, click the green box with a check symbol (located in the
upper right of the page). Your new dashboard with one cell now appears.
You have now created a dashboard with one cell displaying a system measurement based on
data collected using the Telegraf plugins and connection that you configured. You can
continue to explore the new time series data being collected in your bucket by creating
new cells and trying out different visualizations and cell displays.

You can use the InfluxDB 2.0 user interface (UI) to quickly define a scraper that can capture hardware and OS metrics from third-party systems and translate the data into the popular Prometheus format, which is supported by InfluxDB.
Follow the steps below to configure an InfluxDB 2.0 scraper to collect metrics generated by InfluxDB 2.0 into a bucket.
## Configure an InfluxDB scraper to collect InfluxDB 2.0 metrics
Follow the steps here to capture Prometheus format data into an InfluxDB 2.0 bucket.
1. Open a web browser to your InfluxDB 2.0 instance
[localhost:9999](http://localhost:9999). The login screen for the UI (user interface) appears.
2. Log in using your username and password. The **Getting started with InfluxDB 2.0** screen appears.
3. In the navigation bar on the left, click **Organizations** and then click the name of your organization. The **Organization** page appears for the selected organization.
4. Click the **Scrapers** tab. A listing of any existing scrapers appears, listing the **URL** and the **BUCKET** name.
5. Click **Create Scraper**. The **Data Loading** page appears with **Add Scraper Target** options to define a scraper.
6. From the **Bucket** listing, select the bucket that you wan to be use to collect data.
7. Enter the **Target URL** to use for the Prometheus `/metrics` HTTP endpoint. The default URL value is `http://localhost:9100/metrics`.
8. Click **Finish**. The new scraper for Node Explorer appears as a new row in the listing of scrapers and displays the values for the **URL** and the **BUCKET**.
The new scraper for the Prometheus Node Exporter is now collecting data into the InfluxDB bucket you specified.

The [Prometheus Node Exporter](https://github.com/prometheus/node_exporter#node-exporter) and supported collectors capture hardware and OS metrics from third-party systems and translate the data into the popular Prometheus format, which is supported by InfluxDB. You can easily configure Node Exporter-generated output to be scraped into an InfluxDB 2.0 bucket for monitoring in dashboards.
After you have installed the Prometheus Node Exporter, follow the steps below to configure an InfluxDB 2.0 scraper to collect Node Exporter-generated data into an InfluxDB 2.0 bucket.
