## About exporting data to InfluxDB

InfluxDB is a time series database that can store large volumes of time series data, and perform real-time analysis on that data.

Data from your scenario runs can be exported to an external InfluxDB database, enabling you to use the data in applications other than Analysis. The data is output to a running InfluxDB server, versions 1.8 or 2.x.

Using an external database enables data mashing with other tools and data vendors, and using third-party dashboards, such as Grafana, to easily visualize the data. You can download a customized Grafana dashboard from Grafana dashboards.

To enable the data export, you must set up a working connection to the InfluxDB server. For details, see Connect to an external InfluxDB server.

You can export the online run summary data, and/or the raw results data:

- The online summary data is the same data displayed in the Controller graphs. You can configure Controller to export this data in real time to InfluxDB. The data is then automatically exported whenever you run a scenario.

- The raw results data is the raw data collated from the load generators. You can configure Controller to export this collated data during runtime, or trigger export at the end of a scenario run. For details, see Export raw data to InfluxDB .

  You can also configure the connection to the InfluxDB server and raw data export from the command line. For details, see Export raw data to InfluxDB from the command line.

Note: In your InfluxDB configuration file, we recommend you set max-values-per-tag= 0 to allow for unlimited values per tag. For details, refer to the InfluxDB product documentation.

## Connect to an external InfluxDB server

You must set up a working connection to the InfluxDB server in order to export data.

To configure the connection to the InfluxDB server:

1. Prerequisites:

   - Secure Communication. To enable secure communication with your InfluxDB server, you need to use either a self-signed or trusted CA signed certificate. Copy the InfluxDB server certificate to the Controller machine.

     For details on configuring InfluxDB to work with HTTPS, see the InfluxDB documentation.

   - InfluxDB 2.x. By default, the online data export works with InfluxDB version 1.8. To work with InfluxDB version 2.x, you must first run the following InfluxDB commands from the command line interface.

     The same defined database name, username, and password should then be used in the Online Data Export Settings dialog box.

     Copy code

         influx.exe v1 auth create --username User --password Password --token YourToken --org YourOrg --read-bucket bucketId --write-bucket bucketId
         influx.exe v1 dbrp create --bucket-id bucketId --rp DEFAULT_RP --db DatabaseName --default --token YourToken  --org YourOrg

2. In Controller, select Results > Influx Settings, and select the relevant option:

   - Raw Data Export Settings

   - Online Data Export Settings

3. In the displayed Data Export Settings dialog box, configure the connection to the InfluxDB server.

   User interface elements are described below. The parameters vary, depending on the data type to export, and the selected InfluxDB version.

   UI Elements | Description
   --- | ---
   Influx version | Select one of supported versions.
   Server URL | Define the URL or IP address of the external database server, and include the port number. For example: http://my-influx-url:8086 HTTPS URLs are supported, as long as the appropriate certificates have been installed.
   Database name | The name of the database server. Note: For online data on InfluxDB version 2.x, the database name must be the same as used for the bucket you created for the server.
   Username and Password | These settings must be completed if the InfluxDB server requires authentication; otherwise, they can remain blank. Note: For online data on InfluxDB version 2.x, the username and password must be the same as used for the bucket you created for the server.
   Proxy Authentication | Enter proxy server details, if relevant.
   Organization ID | The ID used in InfluxDB for your organization.
   API Token | The InfluxDB token that provides authentication to write to your bucket.
   Bucket name | The name of the InfluxDB bucket where the data is stored.

4. Click Test Connection to make sure the details are correct.
5. Save the settings. The settings remain in effect until changed.

The connection is now ready to export online data whenever you run a scenario.

To export raw data, see Export raw data to InfluxDB .

Tip: To stop automatic export of online data, use the Clear button in the Online Data Export Settings dialog box to remove the settings and break the connection.

## Export raw data to InfluxDB

Exporting raw data to other formats is useful when, for example, the run results are too large for Analysis to handle, or when you want to use test data in applications developed for your specific needs.

The raw data from the run results can be exported to InfluxDB at the end of a scenario run, or collated and exported during runtime. Exporting data at runtime reduces the time spent collating and exporting data at the end of a scenario run.

You can set up the data export in the UI, or from the command line. For details on the latter, see Export raw data to InfluxDB from the command line.

For details on the raw data that is exported to InfluxDB, see Raw data storage tables.

To export raw data to InfluxDB from UI:

1. Set up the connection to the InfluxDB server. For details, see Connect to an external InfluxDB server.

1. To collate the raw data at runtime, in the Collate Settings dialog box select Automatically export results to InfluxDB. For details, see Collate scenario run results.

2. To export the raw data at the end of a scenario run, in the Controller menu, select Results > Export to Influx.

   A notification pane opens. During the export, status and messages are displayed in this pane. When the export is complete, click Close.

## Export raw data to InfluxDB from the command line

You can export raw results data to InfluxDB from the command line.

Enter the following on the command line:

Copy code

    LrRawResultsExporter -source_dir <folder_path>
         [-to_influx -influx_url <server url> -database <database name>] [-user <username> -password <password>]
         [-proxy_server <server url> -proxy_user <username> -proxy_password <password>]
         [-target_dir <folder_path> -to_json]

Parameters:

Option | Description
--- | ---
-source_dir | The location of the source file (.lrr) containing the scenario run results.
-to_influx | Instructs the Exporter to export the raw data to InfluxDB.
-database | The InfluxDB database name.
-influx_url | The InfluxDB server address, including the port number. HTTPS URLs are supported, as long as the appropriate certificates have been installed.
-password | The InfluxDB password.
-username | The InfluxDB user name.
-proxy_url | The proxy server address, including the port number.
-proxy_user | The proxy username. Include if proxy requires authentication.
-proxy_password | The proxy password. Include if proxy requires authentication.
-to_json | Exports the data to the target directory in JSON format (see Export data to JSON). Data can be exported simultaneously to both JSON and InfluxDB.

For details on the raw data that is exported to InfluxDB, see Raw data storage tables.

## Raw data storage tables

The raw data exported to InfluxDB is stored in the database in the following tables:

Table | Description
--- | ---
Error | The error events that occurred during the scenario run.
Transaction | Complete transaction information.
TransactionBreakdown | Transaction breakdown information.
VuserCount | Vuser count during the scenario run.

## Export data to JSON

Exporting test results in JSON format enables you to use the data in applications other than Analysis.

The data exported to JSON is output to a folder, and contained in a set of files:

File | Description
--- | ---
RunInfo.txt | Contains information about the scenario run that generated the processed raw results.
offline.txt | Contains the offline monitor data recorded by the monitors set up in the scenario run.
offlineMetadata.txt | Contains additional metadata for the offline monitor datapoints stored in offline.txt.
*.eve | As in the original .eve files, these files contain all the information recorded from the run: transaction data, transaction breakdown data (including for TruClient), errors (script errors only), and web-related data points.

To export raw data in JSON format, enter the following on the command line:

Copy code

    LrRawResultsExporter -source_dir <folder_path>
    -target_dir <folder_path> -to_json [-f]

Parameters:

Option | Description
--- | ---
‑source_dir | The location of the source file (.lrr) containing the scenario run results.
-target_dir -to_json | Instructs the Exporter to export the raw data to JSON files in the specified target folder.
-f | Forces the execution of the application, automatically overwriting the target directory if it already exists.

## Excluding time zone information from exported data

By default, the result time zone information is included in the exported raw results data.

When exporting to InfluxDB or JSON, you can configure the export to exclude the time zone information.

To exclude the timezone:

1. Open the <installdir>\Analysis\LrRawResultsExporter.ini file. If the file does not exist, create a file by the name LrRawResultsExporter.ini in that location.

2. Add the following line: `IncludeResultTimeZone=0`.

This setting is effective for:

- Controller. If you set this configuration and then select Export to InfluxDB from the Controller user interface, the exported data will not contain the time zone difference.

- Raw Results Exporter. If you use the command line Raw Results Exporter tool to export raw data to Influx or JSON, the exported data will not contain the time zone difference.
