Supported Active Monitors
The following is a list of all of the Active
Monitor types that are supported by WhatsUp Gold.
. The Active Script Monitors let you write either
VBScript or JScript code to perform a check on a device. If the
script returns an error code, the monitor is considered down.
Please be aware that Ipswitch does not support the scripts that you
create, only the ability to use them in the Active Script
- . The DNS monitor is a simple service Monitor that
checks for the DNS (Domain Name Server) on port 53. If no DNS
service responds on this port, then the service is considered
- . The Simple Network Management Protocol is the
protocol governing network management and monitoring of network
devices and their functions. This monitor queries the SNMP device
and tries to match the expected returned value.
- . Telnet is a simple service monitor that checks
for a Telnet server on port 23. If no telnet service responds on
this port, then the service is considered down.
- . The Ping monitor sends an ICMP (ping) command to
the device. If the device does not respond, the monitor is
- . The TCP/IP monitor is used to monitor a TCP/IP
service that either does not appear in the list of standard
services or uses a non-standard port number.
- . The NT Service Monitor lets you check the status
of a service on an Windows machine and attempts a restart of the
service (if the appropriate Administrator permissions exist).
A running Windows Management Instrumentation (WMI) service on the
targeted machine is required for this NT Service Monitor to work
properly. Windows 2000 Service Pack 2 or higher, XP, and 2003 are
installed with the WMI service. WMI is not installed with WhatsUp,
but can be downloaded from Microsoft and installed on Windows
