  • Monitoring server
  • Monitored servers
    • k1cam0, k1cam1 (SL7)
    • k1sum1 (Debian9)
    • k1script (Debian8)

Installation

  • Monitoring server 
    > apt-get install rrdtool gmetad ganglia-webfrontend ganglia-monitor

    • Setting files: /etc/ganglia/gmond.conf and /etc/ganglia/gmetad.conf
