  4. install influxdb

    apt install curl gnupg gnupg1 gnupg2 net-tools software-properties-common

    sudo curl -sL https://repos.influxdata.com/influxdb.key | sudo apt-key add -

    source /etc/lsb-release echo "deb https://repos.influxdata.com/${DISTRIB_ID,,} ${DISTRIB_CODENAME} stable" | sudo tee /etc/apt/sources.list.d/influxdb.list

    show databases show users

  5. install telegraf

    sudo apt install telegraf -y

    sudo systemctl start telegraf sudo systemctl enable telegraf

    sudo systemctl status telegraf

    Configure Telegraf

    In this step, we will configure the Telegraf to use basic input plugins for collecting system metric of the server and using the influxdb as the output plugin.

    cd /etc/telegraf/telegraf.d/

    touch my_config_telegraf.conf nano my_config_telegraf.conf

Global Agent Configuration

[agent] hostname = "Grafana" flush_interval = "10s" interval = "10s"

Input Plugins

[[inputs.cpu]] percpu = true totalcpu = true collect_cpu_time = false report_active = false [[inputs.disk]] ignore_fs = ["tmpfs", "devtmpfs", "devfs"] [[inputs.io]] [[inputs.mem]] [[inputs.net]] [[inputs.system]] [[inputs.swap]] [[inputs.netstat]] [[inputs.processes]] [[inputs.kernel]]

      # Output Plugin InfluxDB
      [[outputs.influxdb]]
        database = "telegraf"
        urls = [ "http://127.0.0.1:8086" ]
        username = "telegraf"
        password = "myP@ssw0rd"

      #Telegraf provides telegraf command to manage the configuration, 
      #including generate the configuration itself, run the command as below.
