Unable to connect from Central manger to Collector

  • 1.  Unable to connect from Central manger to Collector

    Posted Mon February 12, 2024 03:27 AM

    Hi,  After installing Collector, tried to register the Collector with Central manager. Now it has been changed as Managed unit but when i checked in collector GUI getting the error stating that unable to connect to CM, functionality is limited until the connection is restored. Verified the port connectivity, 22 & 8443 are open bidirectionally. By using ping cmd in CLI, able to send & recieve from CM to Collector & collector to CM. How to resolve this issue ?

    Hi,

    Could you please check the two options below?

    1 - Open 3306 port 

    description for this port: Communication between central manager and managed units

    TCP 3306 – MySQL, opened to specific sources (for instance, the Central Manager is open to all managed units; a managed unit is open to the Central Manager)

    You can check the article:

    https://www.ibm.com/docs/en/guardium/10.6?topic=system-guardium-port-requirements

    2- The shared secret key information of your devices must be the same.

    Can you check shared secret key ? 

    Best regards.
