Analyze SFTP Data in Infragistics Reveal
Use the CData API Server to create an OData API on top of SFTP data and visualize live SFTP data in Ingragistics Reveal.
Reveal is a data visualization solution provided by Infragistics and can be paired with the CData API Server and SFTP ADO.NET Provider to build dynamic dashboards from live SFTP data. The CData API Server generates an OData API for SFTP, which is natively consumable in Reveal. In this article, we walk through connecting to SFTP in API Server and connecting to the API Server from Infragistics Reveal to create a simple dashboard.
Connect to SFTP from API Server
CData API Server uses a straightforward, point-and-click interface to connect to data sources and generate APIs.
- Open API Server and click Settings -> Connection -> Add Connection
- Select "SFTP"
- Enter the necessary authentication properties to connect to SFTP.
SFTP can be used to transfer files to and from SFTP servers using the SFTP Protocol. To connect, specify the RemoteHost;. service uses the User and Password and public key authentication (SSHClientCert). Choose an SSHAuthMode and specify connection values based on your selection.
Set the following connection properties to control the relational view of the file system:
- RemotePath: Set this to the current working directory.
- TableDepth: Set this to control the depth of subfolders to report as views.
- FileRetrievalDepth: Set this to retrieve files recursively and list them in the Root table.
Add SFTP Resource Definitions in API Server
After connecting to SFTP, create Resources, which represent API endpoints for SFTP data.
- Click Settings -> Resources -> Add Resource
- Select the SFTP connection
- Select the table you wish to retrieve and click Next
- (Optional) Edit the resource to select specific fields and more
- Save the settings
Add an API Server User
Create a User to connect to SFTP from Reveal through API Server.
- Click Settings -> Users
- Click Add
- Configure a User with access to the SFTP Connection and Resource(s)
(Optional) Configure Cross-Origin Resource Sharing (CORS)
When accessing and connecting to multiple different domains from an application such as Ajax, there is a possibility of violating the limitations of cross-site scripting. In that case, configure the CORS settings in Settings -> Server.
- Enable cross-origin resource sharing (CORS): ON
- Allow all domains without '*': ON
- Access-Control-Allow-Methods: GET, PUT, POST, OPTIONS
- Access-Control-Allow-Headers: Authorization
Save the changes to the settings.
Create a Dashboard in Reveal
With the API Server configured, we can visualize SFTP data in Reveal.
- Log into Reveal and click Dashboards -> New
- Click Data Source -> OData Feed
- Specify the API Server API endpoint URL, for example: https://serverurl/api.rsc
- Select Generic Credentials and specify the API Server username and authentication token
- Select the entity you wish to visualize
- Select fields and choose a chart type
