A zombie process refers to a completed process that retains an entry in the process table, awaiting its parent process to acknowledge its exit status. However, if the parent process exits without signaling its child process to exit properly, the child process enters a zombie state.

Configure the Zombie Process plugin and calculate the number of Zombie Processes created in the server.

How it works?

  • Log-in to your Site24x7 account. Sign up here if you don't have one.
  • Download and install the latest version of Site24x7 Linux Agent
  • Install the Zombie Process plugin
  • The agent will execute the plugin and push the data to the Site24x7 server


  • Our plugin uses 'top' command to get the number of Zombie Process count

Zombie Process plugin installation:

  • Create a directory with the name "zombies", under Site24x7 Linux Agent plugin directory - /opt/site24x7/monagent/plugins/zombies
    cd /opt/site24x7/monagent/plugins/
    mkdir zombies
  • Download the file "zombies.py" from our GitHub repository and place it under the "zombies" directory
    wget https://raw.githubusercontent.com/site24x7/plugins/master/zombies/zombies.py
  • Once the plugin file is downloaded, the agent will mark it up in the next data collection and you can view it in Site24x7 client


  • Reports back the number of Zombie Processes present in the server.
