DX Gateway

The DX Gateway package consists of On-Prem Gateway, On-Prem ITSM (CA Service Management), RESTmon, and Log Collector (Logstash). You can install all the components or only the required component by modifying the common configuration file.
  • On-Prem Gateway:
    The On-Prem Gateway is an interfacule which collects alarms from
    DX SaaS
    and sends alarms to the On-Premise third-party products through channels. The On-Prem Gateway acts as a poller which collects alarm data periodically. The On-Prem gateway and the third-party product must be installed on the same system. For more information, see the On-Prem Gateway section.
  • On-Prem ITSM:
    On-Prem ITSM (Incident Manager) integrates with CA Service Management (CA SM) to track and manage alarms raised in
    DX SaaS
    . When an alarm occurs in
    DX SaaS
    , a ticket is created in the CA Service Management system. For more information, see the Integrate CA Service Management section.
  • DX RESTmon:
    Integrates with third-party products or services over REST APIs and pulls data into DX Operational Intelligence (OI). For more information, see the DX RESTmon section.
  • DX Log Collector:
    The Log Collector collects syslogs from network devices or servers and ingests into OI. The Log Collector also includes Filebeat to collect logs of the DX Operational Intelligence containers and parses them based on the predefined patterns. For more information, see the DX Log Collector section.

Prerequisites for DX Gateway
Review the following prerequisites before deploying DX Gateway.
Hardware Requirements
Deploy DX Gateway on systems with the following minimum resources:
  • Memory - 16GB of RAM
  • CPU - 4 Cores
  • Storage - 100 GB
DX RESTmon runs on Java processes so you can tune the memory allocation pool settings for the JVM to optimize performance based on your environment. The default memory allocation for a Java process is 2GB, we recommend you to increase it to a minimum of 4GB for optimum RESTmon performance.
For example, you can update the Java heap size to 8GB in RESTmon by executing the run.bat or run.sh from
\Restmon, and add
Configuration Requirements
  • Access to DX Operational Intelligence (DX OI).
  • Access to
    DX SaaS
    . You can download the DX Gateway package only from
    DX SaaS
  • Verify that OpenJDK 14 is installed on the system where you want to deploy the DX Gateway. As a prerequisite, ensure that Java is installed and the JAVA_HOME environment variable points to your Java installation directory.
  • On-Prem Gateway
  • On-Prem ITSM
    • Review the On-Prem ITSM specific requirements before you deploy the DX Gateway. This includes creating and adding the Channel. For more information, see the Integrate Service Management section.
  • DX RESTmon
    • DX RESTmon supports JSON- and XML-formatted payloads. To use XML-formatted payloads, enter xml2json as a value to the xml_ns field in the schema. For JSON-formatted payloads, you do not need to provide any value.
    On-Prem ITSM and DX RESTmon both run on the default 8080 port (HTTP). If you are installing both the components on the same server, ensure you set a different port for DX RESTmon or On-Prem ITSM by modifying the
    value in the respective <
    >\config\application.properties file.
  • Log Collector
    • The Log Collector installation works only on a Linux Operating System.
    • Do not modify the value (
      ) for the
      parameter. The Log Collector creates the
      folder and places all the required files in this folder.
    • The Log Collector does not require the Tenant ID, Username, and Password fields. The URL in the
      parameter is sufficient for it to collect data.
    • The Log Collector also includes Filebeat to collect logs of the DX Operational Intelligence containers and parses them based on the predefined patterns.

Contents of the DX Gateway Package
The DX Gateway package consists of the following files and folders:
  • Config
    : This folder contains the
    file which is required to configure the common
    DX SaaS
    connection details.
  • installer.bat and installer.sh
    : Use the
    to start the installation on a Windows or Linux computer respectively.
  • Scripts
    : This folder contains the scripts to start and stop the installers.
  • Onprem
    : This folder contains the On-Prem Gateway configuration files.
  • Onprem-Itsm
    : This folder contains the Onprem-ITSM configuration files.
  • Restmon
    : This folder contains the DX RESTmon configuration files.
  • Logstash
    : This folder contains the Log Collector syslog configuration files.
Configure and Deploy DX Gateway
The common configuration file in DX Gateway enables you to deploy all the four components (On-Prem Gateway, On-Prem ITSM, RESTmon, and Log Collector) at the same time or individually based on your requirement.
  • Ensure that you have downloaded the DX Gateway package.
  • Ensure that you have reviewed the DX Gateway Prerequisites section.
  • The following procedure lists only the parameters which require user input. All other parameters in the
    file are auto-populated when you run the DX-Gateway installer.
Follow these steps:
  1. Navigate to the
  2. Edit the following parameters in the
    • dxsaas_tenant_id
      : Enter the
      DX SaaS
      tenant name. For example,
    • dxsaas_username
      : Enter the
      DX SaaS
      username. For example, .
    • dxsaas_password
      : Enter the password for the user.
      Enter the password as clear text and leave the
      field to
      . The application encrypts the password and sets the encryption field to
      If the service account user is enabled for your tenant, provide that service account user name and password for integrations. In addition to these parameters, also ensure to update the

      : Enter true to enable the proxy configuration. Default: false.
    • proxy_hostname:
      Enter the hostname which has proxy configured.
    • proxy_port
      : Enter the port for the proxy hostname. Default:
    • proxy_protocol

  7. Enter
    for each of the components, you want to install. The following snapshot shows that RESTMon is not selected, and Incident Manager and On-Prem Gateway are selected for installation.

  8. Verify the deployment is successful by viewing the
    folder. The Logs folder is created once the installation is initialized for each of the components. For more information, see the DX Gateway Logs section.
You have now successfully configured the components.
For more information on using these components, see the following sections:
DX Gateway Logs
folder is created once the installation is initialized for the components. The logs folder contains all the individual component logs.
Ensure you provide the required
permissions to the folder before you trigger the installation. For example, on Linux:
chmod 755 -R DX-Gateway
The following are the log files created in the logs folder.
  • DX Gateway: Logs/dxgateway.log *
    This logs issues specific to the DX Gateway startup and initialization.
  • On-Prem Gateway: Logs/webhook_gtw.log
  • On-Prem ITSM: Logs/incident_manager.log
  • DX RESTmon: Logs/restmon.log
  • DX Log Collector: Logs/logstash.out
