How to Сreate Devices and Targets
An HTTP/S monitoring checks a single URL for availability, performance, proper content, and errors. It supports POST and GET requests, cookies, form submissions, custom headers, password-secured sites (basic HTTP/S authorization as well as cookie/script authorization mechanisms), and timeout thresholds.
HTTP/S monitoring validates security certificates, check certificate authority, and check for expiration. It can also be configured to send you reminders when the certificate expiration date is approaching.
You can convert request parameters values to Context Parameters to pass in values, for example, retrieved from a response of another device. You can set up context parameters for the URL, Headers, request body (for Post, Put, Patch request types), and for the custom script in the Prepare script field. For details, see How to Use Context Parameters in HTTP(S) Requests.
Configuring a Request
Enter the URL of the page you wish to perform the task on. It should be formatted as such: www.example.com.
You can turn on a visually friendly input mode by clicking the Detailed switcher on the top of the section.
SSL/Certificate Check for HTTPS task
Secure Socket Layer SSL Certificate Monitoring is a standard aspect of HTTPS monitoring.
For an HTTPS task, the following additional options are available:
- Authority: verifies whether a certificate chain contains a root certificate that is trusted, or not trusted.
- Common Name (CN): validates that an address you navigate to matches the address certificate the address was signed to.
- Date: verifies the certificate expiration date.
- Revocation: validates that the certificate’s chain of trust doesn’t contain a revoked certificate.
- Usage: verifies a certificate chain for the improper use of an intermediate certificate.
- Expiration Reminder in Days: a reminder that notifies (as an error) about certificate expiration.
- Client Certificate: client certificate name.

Completion Timeout (in seconds)
Enter the number of seconds the task should wait for a response from the web page before ending the task and returning an error. If this is left blank the default timeout for a task is 120 seconds.
You can send a GET or a POST request to the web page. Selecting a GET request will simply retrieve data from the web server. Selecting a POST request indicates that you are including a set of data for the server to act upon. Note: if you set the request type to POST but do not specify a POST parameter in the additional parameters section below, the POST value will default back to get upon saving the task.
Content Validation Keywords are used to ensure that the expected content was loaded onto a web page.
In the Keyword fields, you can specify one or more words or phrases that you wish to search for in the web page content. If the expected keywords are not found, the task will return an error.
You can enter multiple strings into the keyword fields. The values you enter can be separated by logical expressions as follows:
{[(“keyword1″&”keyword2″)|!”keyword3”]}
]} – keyword expression end;
where
{[ – keyword expression start;
() – grouping brackets;
& – logical AND;
| – logical OR;
! – logical NOT;
“string” – a keyword;
A successful keyword expression must include the start and end brackets as follows:
{[“keyword”]}
Basic authentication is used to allow users to access content on some websites.
Username: contains a username for HTTP/S basic or digest access authentication.
User Password: contains a password for HTTP/S basic or digest access authentication.
Read the article on Authentication username and password for more information.
The option allows to add any additional custom headers in the following format (by “=” symbol, each header should start from a new line):
Header_name_1 = "value" Header_name_2 = "value"
Header Name: specify the name of the parameter as it will appear in the request.
Value: enter the value associated with the name of the parameter.
Post Data options for Post requests
If Post request type was selected you can specify the following Post parameters:
- Name: the name of the parameter as it will appear in the request.
- Value: the value associated with the name of the parameter.
Read the article on Authentication username and password for more information.
The DNS Options feature allows users to choose how domain name server (DNS) requests are conducted during a monitoring task.
To specify the mode of resolving hostnames, in the DNS Resolve Mode section, select one of the available modes. For more details on the feature configuration, see DNS Mode Options.
The Custom DNS Hosts section contains the mappings of IP addresses to hostnames.
To specify the mapping, enter the IP address and the host name in the corresponding fields.
See also: DNS Mode Options.
Prepare Script and Post Script
The fields can contain C# code, which can be used for specific POST, GET, URL data or for validating or publishing custom headers. Please see the Using Prepare Script and Post Script article or contact technical support for more details on usage.
