Required Ports For Spotlight

Spotlight Diagnostic Server must be able to maintain bi-directional communication with every monitored host.  Additionally, it must be capable of sending and receiving data from every Spotlight Client application in addition to sending data to any properly configured Spotlight Cloud.  Spotlight utilizes designated ports for such communication protocol which facilitates the monitoring.  These ports also allows for provisioning data collection between Spotlight and monitored hosts along with displaying data in Spotlight Client and Cloud applications.

In order to leverage the described communication, the following guidelines should be followed:

  • The required ports below need to be configured.
  • There must not be any firewall blocking the port traffic.
  • There must not be any other services using these ports.
  • The ports should not be configured as ephemeral ports.

 
On the server hosting Spotlight Diagnostic Server:

Description

3843

TCP

Inbound

This port is used by the Spotlight Client to communicate with the Spotlight Diagnostic Server.

3166

TCP

Inbound/Outbound

This port is used by the Spotlight Diagnostic Server to communicate with the Spotlight OOP Collector process on the same host. No external connections are required on this port.

40403

TCP

Inbound

This port is used by the Spotlight Client to communicate with the Spotlight Diagnostic Server.

80

TCP

Outbound

This port is used by the Spotlight Diagnostic Server to communicate with Spotlight Cloud feature.

Description

3843

TCP

Outbound

This port is used by the Spotlight Client to communicate with the Spotlight Diagnostic Server.

40403

On the monitored servers:

Windows servers:

Port

Protocol

Direction

Description

135

TCP

Inbound/Outbound

The Spotlight Diagnostic Server uses WMI queries to retrieve performance counter information from monitored Windows Server and hosts of database connections. Verify TCP port 135 is open on monitored Windows server and hosts of database connections. **Note: Port 135 is the default port used by WMI. To determine and limit the range of ports used by WMI refer to Spotlight Help documents.

 

Servers hosting SQL Server database:

Port

Protocol

Direction

Description

135

TCP

Inbound/Outbound


The Spotlight Diagnostic Server uses WMI queries to retrieve performance counter information from monitored Windows Server and hosts of database connections. Verify TCP port 135 is open on monitored Windows server and hosts of database connections.

1434

UDP

Inbound/Outbound

SQL Server uses UDP 1434 to locate the SQL Server instance port number. If UDP 1434 is closed then the SQL Server instance port number must be included in the connection string used to connect Spotlight to the SQL Server instance. **Note: Port 1434 is the default port used by SQL Server. Otherwise, the default port used by the instance must be included in connection string used in Spotlight to connect to this instance.

 

Unix servers:

Port

Protocol

Direction

Description

Port 22 or designated port for SSH

 

Inbound/Outbound

Verify the port number for SSH (secure shell) connection to the Unix/Linux machine is open. The default port number is 22.

 


Some of the possible application errors received with blocked ports:

  • Unable to connect to monitored host: “The RPC server is unavailable.”
  • Unable to connect to monitored host: "No connection could be made because the target machine actively refused it”
  • Spotlight application hangs at startup and unable to connect to Diagnostic Server host: "No server found on the specified host."
  • Unable to open Planned Outage or Alarm Actions windows
  • Unable to upload data to Spotlight Cloud: "Diagnostic Server - Spotlight Cloud data transfer Spotlight Cloud data transfer failed"
