Sensors

ICMP ping

The ICMP ping sensor allows to check if there is a host in the network using the ICMP ping scanning method.

You can:

  • specify the number of scan retries in the Retry count field;
  • set the packet lifetime in the TTL (Time To Live) field; 
  • set the scanning packet size (in bytes) in the Packet size field.

TCP/IP

The TCP/IP sensor allows to check availability of any TCP port.

Select the TCP port to be checked in the drop-down Server port list or enter it manually. If the remote port is open, the monitor will change its color to green; otherwise, it'll turn red. Sensor check errors will color the monitor black.

HTTP

The HTTP sensor allows to check the content of a remote HTML page.

Enter the address of the HTML page to be checked into the Request URL field. The following string format is used:

[http://][example.com][:port]/[dir[/...]][index.html]

Thus, the only mandatory element is the forward slash specifying the site root. The prefix http:// is optional. The site (domain) name is also optional. If no name is specified, then the name from the device properties is used. If a name is specified, it is used only in the Host field of the GET-request, but it is not used for the IP resolution. If no port is specified, the default port is used (80). The path and/or the HTML page title may be specified after the slash. Examples:

http://www.example.com/dir1/dir2/page.html

example.com:8080/

/folder/index.php

Enter the lines you want to check for into the multi-line text field. You can also set the check rules:

  • Contains or Doesn't contain: check if the entered lines must be present or absent in the HTML page, respectively;
  • Any or All: check if any line must be present or all of them.

If the selected conditions are true, the monitor will change its state to green; otherwise, it'll turn red. Sensor check errors will color the monitor black.

FTP

The FTP sensor allows to check the FTP-server performance.

Enter the username and password to be used during the authorization on the FTP-server into the User and Password fields respectively. Specify the Server port in the corresponding field.

If the selected conditions are true, the monitor will change its state to green; otherwise, it'll turn red. Sensor check errors will color the monitor black.

SMTP, POP3, IMAP and Telnet

The SMTP, POP3, IMAP and Telnet sensors allow to check uptimes of the corresponding servers.

If the server works fine, the monitor will change its state to green; otherwise, it'll turn red. Sensor check errors will color the monitor black.

Event log

The Event log sensor allows to check if there's a record (its type, category, number and content) in Windows Event Log both on local and remote computers.

  • Set the time period in the From and For the last fields;
  • Set the queried record identifier in the ID field;
  • Select the message type (Error, Information, Warning, Audit success, Audit failure, Success) from the Event type drop-down list.

If you need to find a specific string in the record, then enter it (or its part) into the Message field.
Important note! Records will be filtered only by the set criteria.

Registry state

The Registry state sensor allows to check whether a particular key and its value is present in the registry, using a set of rules, both on local and remote computers.

Select the registry section you would like to work with in the Key drop-down list. Then set the path to the parameter (section) and the name of the parameter in the mandatory fields Subkey and Field, respectively. Example of a path to a section: Software\Microsoft\Windows\CurrentVersion\Run.

In the Enter data to find here field specify a value to be used by a rule. To enter binary data use hexademical notation 0x (e.g. 0xABC123).

Select one of the sensor rules from the Rule drop-down list:

  • Exists: the specified parameter is present in the registry;
  • Does not exist: the specified parameter is not present in the registry;
  • Equal: the registry value is exactly equal to the specified value;
  • Not equal: the registry value is not exactly equal to the specified value;
