    Key Features

    • System Requirements: Establish minimum resource allocations for computers hosting MID Servers.
    • ECC Queue: Understand the External Communication Channel (ECC) Queue, which stores jobs for the MID Server until it is ready to process them.
    • MID Server Dashboard: Utilize reports and gauges to monitor the MID Server's ongoing operations and performance.
    • MID Server Properties and Parameters: Adjust settings to control the behavior of all MID Servers or specific instances as needed.
    • Protected Records and Reserved Characters: Be aware that certain MID Server records cannot be altered and specific characters are prohibited in XML-based passwords.
    • Privileged Commands: Use default and custom SSH commands with higher privileges to gather required information from host servers.
    • MIDSystem Methods: Access various methods to retrieve information about the MID Server using MIDSystem variables.
    • MID Server Heartbeat: Configure the response check interval for the MID Server, which defaults to every 5 minutes.
    • JVM Memory Size: Adjust the Java Virtual Machine (JVM) memory size to better suit the workload demands of your MID Server.
    • Pause Functionality: Temporarily pause the MID Server to halt polling of the ECC Queue or to stop sending Discovery results to the instance.

    Key Outcomes

    By following the MID Server reference information, ServiceNow customers can effectively configure their MID Servers, monitor performance, and ensure secure communication between systems. This leads to improved operational efficiency and reliability in service delivery.

    Reference topics

    System requirements
    Use the minimum system requirements to allocate resources for computers hosting MID Servers.
    ECC Queue
    Learn about the External Communication Channel (ECC) Queue, which is the connection point between the MID Server and the instance. Jobs that the MID Server needs to perform are saved in this queue until the MID Server is ready to handle them.
    MID Server Dashboard
    Use the reports and gauges in the MID Server dashboard to monitor ongoing operations.
    MID Server properties
    Use MID Server properties to control the behavior of all MID Servers or a particular MID Server.
    MID Server parameters
    Use MID Server parameters to control the behavior of a particular MID Server.
    MID Server protected records and reserved characters
    Some MID Server records cannot be altered. Certain special characters are pre-defined in XML and cannot be used in passwords.
    MID Server privileged commands
    To discover certain information on a host server, the MID Server must run SSH commands with higher privileges. The platform provides default privileged commands for the MID Server to use and the ability to add additional commands to the system.
    MIDSystem methods
    MIDSystem variables (referred to by the variable name ms.) provide a variety of methods to get information about the MID Server.
    MID Server heartbeat
    Configure the interval that the instance uses when it checks the "heartbeat" of MID Server. By default, the instance checks the MID Server for a response every 5 minutes.
    Set JVM memory size
    Modify the JVM setting for your MID Server from the default size to suit the amount of work your MID Server does in your network.
    Pause the MID Server
    Pause the MID Server to temporarily prevent it from polling the ECC Queue for work or sending Discovery results back to the instance.
