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:
On the server hosting Spotlight Diagnostic Server:
This port is used by the Spotlight Client to communicate with the Spotlight Diagnostic Server.
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.
This port is used by the Spotlight Diagnostic Server to communicate with Spotlight Cloud feature.
This port is used by the Spotlight Diagnostic Server to communicate with Spotlight Cloud feature and vCenter monitoring.
On the user client machines hosting Spotlight client application:
On the monitored servers:
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:
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.
Verify the port number for SSH (secure shell) connection to the Unix/Linux machine is open. The default port number is 22.
