HTTP/HTTPS
HTTP/HTTPS Device Driver allows Iotellect Server to exchange data with external web servers using HTTP or HTTPS protocol. It allows to form various raw requests (GET, POST, etc.) and inject responses (both their headers and contents) into platform core for further processing.
 | A web server is a computer program that delivers (serves) content, such as web pages, using the Hypertext Transfer Protocol (HTTP), over the World Wide Web. |
HTTP/HTTPS driver also provides monitoring of any web server (Apache, IIS, etc.) by checking whether a monitored device accepts HTTP(S) requests and responds with correct pages. The driver supports GET and POST requests, authorization and other options for HTTP(S) requests.

Device Account Properties
Connection Properties
Connection settings define how Iotellect Server communicates with a certain HTTP server. These settings can be accessed using Edit Device Properties action of the Device Context. Here is a list of available connection properties:
Setting | Description |
Address | IP address or host name of the HTTP server. |
Protocol | HTTP or HTTP Secure (HTTPS). |
Protocol Version | Version 1.1 or 2.0. |
Port | Port the HTTP server is running on. |
URL | Path to a monitored resource located on the specified HTTP server. |
Request Method | HTTP request methods are currently supported: GET, POST, PUT and DELETE. |
Post Data | Data to be submitted with POST request, in the string form. |
Put Data | Data to be submitted with PUT request, in the string form. |
Encoding | Specifies the encoding of the Post Data and Reply content. |
Enable Authentication | Enables realm authorization (if it's required). |
Username | User name to be used for authorization. |
Password | Password for authorization. |
Domain | Domain for NTLM authorization. |
Workstation | Workstation for NTLM authorization. |
Certificate | Alias of an SSL/TLS certificate to use for authentication. The certificate with that alias must exist in the Client Certificate storage of the Iotellect server. |
Proxy | Address of HTTP/HTTPS/SOCKS proxy to use. |
Additional HTTP Headers | Additional information to be included in request header. Specified as a table with the following fields:
|
Agent | User agent string. |
Timeout | HTTP server operations timeout. |
Disable SNI Extension | Disables Server Name Indication extension of the TLS protocol. |
Device Assets
Assets are not supported by the driver.
Device Settings
HTTP device driver creates the only device setting variable indicating the result of HTTP request. This variable includes the following fields that may be analyzed using different Iotellect modules:
Property | Description |
Successful | Indicates that web server monitor had no error during last page read. |
Response Time, milliseconds | Server response time. |
Reply Code | HTTP response code. |
Headers | HTTP response headers table. |
Reply | HTTP response body, i.e. web page contents. |
Error | Error text, or NULL if request was successful (even if HTTP response code is not 200/OK). |
Reply Binary Data | Binary version of the reply. |
Device Operations
Execute HTTP Request
This operation sends a raw HTTP GET, PUT, DELETE or POST request to the device and returns the output. Input values include URL, request method, POST data and additional HTTP headers. Values returned are success flag, response time, HTTP reply code, headers, returned page text and error text.
Device Events
No events provided by the driver.
Connection Handling
HTTP device is deemed Online if no error occurred during connection and HTTP request execution, and valid HTTP response was obtained.
Synchronization Details
HTTP monitor connects to the IP host, sends an HTTP request built using provided configuration (port, URL, request type and data, HTTP headers, agent, timeout) and analyzes the response.
 | If authentication is enabled in the settings and Basic Access Authentication is required to access a web page the driver also sends an authorization request. |
