Sensor not displayed in the resource tree

Prev Next

After adding the Sensor and establishing trust, if the Sensor is not displayed in the resource tree, perform the following steps for troubleshooting:

Task

  1. Capture traffic using Wireshark in the Manager.
  2. Verify if the Manager is receiving UDP response packets from the Sensor.
  3. Configure the firewall to allow UDP traffic if response packets are not coming.
  4. Verify if the Manager system has multiple NIC cards. If yes:
    • For Windows-based Manager, open <Manager_Install_Dir>\bin\tms.bat.

      Note

      The default installation path for Windows-based Manager is %programfiles%\Trellix\IPS Manager\App.

    • For Linux-based Manager, open open tms.sh by executing the command edit tms.sh
  5. Later, modify the following line to assign the relevant IP address that is also used in the Sensor configuration: Set JAVA_OPTS=%JAVA_OPTS% -Dlumos.fixedManagerSNMPIPaddress=""restart Manager

    You can enable detailed debugging messages by modifying the following files:

    • For Windows-based Manager, <Manager_Install_Dir>\config\log4j_ism.xml file
    • For Linux-based Manager, log4j_ism.xml file. To open this file, execute edit log4j_ism.xml

    Later, add and change the following lines if it is existed:

    • <category name="iv.core.DiscoveryService"> <priority value="DEBUG"/></category>
    • <category name="iv.core.SensorConfiguration"> <priority value="DEBUG"/></category>
