Abstract

Refer to the following troubleshooting resources for the Cortex XDR agent for Linux.

Resource

Description

Services and Processes

Services:

  • /opt/traps/bin/pmd‑ Running with root privileges.

Processes:

  • /opt/traps/bin/dypd or /opt/traps/bin/dypdng (depending on the Linux kernel version) - Running with root privileges, pmd starts and stops a single dypd helper process.

  • /opt/traps/analyzerd/clad- Unprivileged process running inside the sandbox, pmd starts and stops a single analyzerd helper process.

  • /opt/traps/analyzerd/spmd‑ Unprivileged process running inside the sandbox, pmd starts and stops a single analyzerd helper process.

  • /opt/traps/python/payload/lted‑ Unprivileged process running inside the sandbox, pmd starts and stops multiple lted processes on demand.

  • /opt/traps/python/payload/pyxd

Memory usage of lted processes

All lted instances are forks of the same process, sharing most of the physical memory pages. Using ps and sum of RSS of all lted instances could be misleading, since the same shared memory pages will be counted several times. The correct way to analyze memory usage of lted processes is using PSS (Proportional set size), which can be calculated by the smem utility.

Cortex XDR agent logs

Indicates information, warnings, and errors related to Cortex XDR that are stored on the endpoint, accessible to privileged users only.

  • Installation logs: /var/log/traps-install.log

  • Agent logs: /var/log/traps/

Kernel Module
