How to Create Devices and Targets

How it Works

Dotcom-Monitor checks a remote mail server to verify that users can access their email account via Microsoft Exchange ActiveSync protocol then sends an email to check for the successful delivery of the email message. After the email delivery has been deemed successful, the email is deleted.

Creating a Target

Email Address

Defines the destination email address.


Contains a password for authentication.


Pressing the discover button begins a Microsoft Exchange special service called Autodiscovery. The Autodiscover service simplifies the provisioning of your client by returning the required system settings after you enter your e-mail address and password.

If the Autodiscover service is configured properly at the mail server, then the PORTTarget Mail Server, and USE SSL options will be filled in automatically.

Time Validation Threshold (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.


When enabled the connection over SSL will be requested.

Accept all SSL certificates

When enabled all certificate-related errors (like Certificate Authority, Certificate Date, Certificate Common Name, etc.) are ignored.

Server Information

Target Mail Server: Specifies mail server address.

Port: Specifies mail server port number.

Domain\Username: The field contains a domain (depending on a configuration of a server, a domain name may be not necessary) and a username for authentication.

DNS Options

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 allows to set up the mapping of IP addresses to hostnames. IPv6 and IPv4 DNS resolution is supported.

To specify the mapping, enter the IP address and the hostname in the corresponding fields.

Error Filter

You can set a filter to ignore specific error types and codes. In the Error Filter section, you can filter out certain user-configurable errors. For example, DNS errors could be filtered out based on who is responsible for DNS server operations. You can create filters that will ignore specific errors that you know may occur and are not relevant to the goal of a specific device.

In addition, you can set up the system to ignore a range of error codes using a dash, or multiple error codes using semicolons as a separator.

For example, if on one particular device, you do not care about 404 errors, you can filter them out so that you do not receive alerts when they are detected.

Note that if an error matches the filter conditions, the error will not be reflected on the reports and can’t be tracked down.
