      Description

      We run dmesg -T > /dev/null 2>&1 instead of $sudo dmesg -T > /dev/null 2>&1 to see if human readable timestamps are supported.

      # Print out any Out of Memory killed process messages.
      - command: shell.exec
        params:
          system_log: true
          working_dir: src # Temporary files created in src will be cleaned up in "pre".
          script: |
            ${set_sudo}
            # Use dmesg -T option, if supported, to display timestamps.
            dmesg=dmesg
            dmesg -T > /dev/null 2>&1
            if [ $? -eq 0 ]; then
              dmesg="dmesg -T"
            fi
            $sudo $dmesg 2> /dev/null > dmesg.txt
            if [ $? -ne 0 ]; then
              echo "Cannot check for OOM (Out of memory) killed processes on this platform"
              exit 0
            fi
            egrep -i '(Out of memory|OOM[- ]killer|Killed process)' dmesg.txt > oom.txt
            if [ -s oom.txt ]; then
              echo "OOM (Out of memory) killed processes detected"
              cat oom.txt
            else
              echo "No OOM (Out of memory) killed processes detected"
            fi
