Configuring the Management Server


If you have installed PLOSSYS Output Engine with a separate management server or in a cluster, perform the following instructions on the management server.


Operating System Settings

  1. In an editor, open the following configuration file:

    /etc/sysctl.conf
    
  2. Adjust the necessary operating system settings

    • for high-volume systems:

      net.ipv4.ip_local_port_range = 10000 65535
      fs.file-max = 1058576
      
    • for working with Elasticsearch:

      vm.max_map_count = 262144
      

Elasticsearch

  1. On the management server, edit the following file:

    /opt/seal/etc/seal-elasticsearch/elasticsearch.yml
    
  2. Add the following lines:

    network.host: "0.0.0.0"
    discovery.type: "single-node"
    
  3. Save the file.

  4. On the management server, edit the following file:

    /opt/seal/etc/seal-elasticsearch/jvm.options
    
  5. Set Max_Heap_Size to at least 50 % of the server's RAM.

    –Xmx<ram_mb>m
    –Xms<ram_mb>m
    

    Example - 2048 MB

    –Xmx2048m
    –Xms2048m
    

    Caution - value

    <ram_mb> is the amount of RAM in Megabyte. You have to set –Xmx<ram_mb>m and –Xms<ram_mb>m to the same value, otherwise Elasticserach will not start.

  6. Save the file.

  7. Restart Elasticsearch:

    sudo systemctl restart seal-elasticsearch
    

Kibana

  1. In the /opt/seal/etc/kibana.yml file, activate the following setting:

    server.host: "0.0.0.0"
    
  2. Restart Kibana:

    sudo systemctl restart seal-kibana
