Install and Setup TIG Stack on Fedora 30

Last Updated:

In this guide, we are going to learn how to install and setup TIG stack on Fedora 30 for monitoring system metrics such as memory, disk, logged in users, system load, swap usage, system uptime, system processes. TIG stack is a group of powerful open-source monitoring tools, Telegraf, InfluxDB and Grafana where;

  • Telegraf is an open-source server agent for collecting and sending metrics and events from databases, systems, and IoT sensors.
  • InfluxDB is an open-source time series database and provides datastore for metrics, events, and real-time analytics.
  • Grafana is a data visualization and monitoring tool and supports time series datastores such as Graphite, InfluxDB, Prometheus, Elasticsearch.

Install and Setup TIG Stack on Fedora 30

In order to setup TIG stack on Fedora 30, you need to install and configure each component of the stack. We have already covered the installation of Telegraf and InfluxDB on Fedora 30 in our previous guides. See the links below for the installation procedure.

Install Telegraf on Fedora 30/Fedora 29

Install InfluxDB on Fedora 30/Fedora 29

Install Grafana on Fedora 30

Grafana can be installed on Fedora 30 using the RPM binary package or directly via Grafana repository using DNF package manager. To install using an RPM binary package,

dnf install

To install Grafana from Grafana repository, you need to create the repository as shown below;

cat > /etc/yum.repos.d/grafana.repo << EOF

Then install Grafana via the dnf command.

dnf install grafana

Start the Grafana server and enable it to run on boot.

systemctl status grafana-server
systemctl enable grafana-server

Open Grafana port on firewalld to allow external access.

firewall-cmd --add-port=3000/tcp --permanent
firewall-cmd --reload

You can now access Grafana via the address http://server-IP:3000. The default credentials for username and password are admin. Reset the password when prompted and proceed to Grafana dashboard.

Learn how to Install Grafana on Fedora 29, Debian 9, Ubuntu 18.04 by following the links below;

Create InfluxDB Database and User

Once you have installed InfluxDB, you need to create a database that will used to store the time series metrics collected by the Telegraf agent. Hence, connect to InfluxDB and create a database and databaseas shown below;

Connected to http://localhost:8086 version 1.7.6
InfluxDB shell version: 1.7.6
Enter an InfluxQL query
> create database telegraf
> use telegraf
Using database telegraf
> create user telegraf with password 'StrongP@SS'

You can verify this by running the commands below;

> show databases
name: databases
> show users
user     admin
----     -----
telegraf false

Test connection to the database using the username and password created.

influx -username 'telegraf' -password 'StrongP@SS' -database telegraf
Connected to http://localhost:8086 version 1.7.6
InfluxDB shell version: 1.7.6
Enter an InfluxQL query

Configuring Telegraf

Once the installation of Telegraf is done, proceed with configuration. Telegraf is plugin-driven with 4 distinct plugin types:

Well, in this guide, we are going to configure TIG stack to monitor system memory usage, system processes, disk usage, system load, system uptime and logged in users.

The default configuration file for Telegraf is /etc/telegraf/telegraf.conf. Before we can continue, we will make a backup of the default configuration.

mv /etc/telegraf/telegraf.conf /etc/telegraf/telegraf.conf.bak

Next, create a new configuration with your specific metrics. To generate a configuration file, Telegraf provides a command line tool, telegraf, that can be used to define specific input plugins, output plugins.

For example to to generate a configuration file with input plugins such as system memory usage, cpu, swap, load, logged in users, processes and define output as InfluxDB, run the command below;

telegraf config -input-filter cpu:mem:swap:system:processes -output-filter influxdb > /etc/telegraf/telegraf.conf

Next, edit the configuration file to define the URL for InfluxDB, the metrics database, the user and password to connect to metrics database such that your Telegraf configuration file looks like below without comment lines.

  interval = "10s"
  round_interval = true
  metric_batch_size = 1000
  metric_buffer_limit = 10000
  collection_jitter = "0s"
  flush_interval = "10s"
  flush_jitter = "0s"
  precision = ""
  debug = false
  quiet = false
  logfile = ""
  hostname = ""
  omit_hostname = false
  urls = [""]
  database = "telegraf"
  username = "telegraf"
  password = "StrongP@SS"
  percpu = true
  totalcpu = true
  collect_cpu_time = false
  report_active = false
  ignore_fs = ["tmpfs", "devtmpfs", "devfs", "overlay", "aufs", "squashfs"]

To learn more options used, check Telegraf administration configuration page.

Once you are done with Telegraf configuration, restart it.

systemctl restart telegraf

Telegraf configuration tests

Telegraf enables you to run configuration tests outputing metrics to stdout. To run a general test for all metrics defined;

telegraf --config telegraf.conf --test

To run configuration test for a specific metric for example, system input plugin;

telegraf -test -config /etc/telegraf/telegraf.conf --input-filter system
2019-05-08T03:01:29Z I! Starting Telegraf 1.10.3
> system, load1=0,load15=0,load5=0,n_cpus=1i,n_users=2i 1557284489000000000
> system, uptime=33495i 1557284489000000000
> system, uptime_format=" 9:18" 1557284489000000000

Configure Grafana

Add Data source

Login to Grafana dashboard as admin with your new password.

install and setup TIG stack  on Fedora 30

Next, you need to add the data source. In this case, our data source is InfluxDB, hence click on Add data source and select InfluxDB.

grafana influxdb datasource

Set the Name and URL of the InfuxDB data source (Leave it as http://localhost:8086 for local connection).

InfluxDB data source name and URL

Scroll down and set the InfluxDB database connection details defined above.

Set influxdb database credentials

Next, click on Save & Test to test the connection to the InfluxDB database.

test connection to InfluxDB database

Setup Grafana Dashboard

You can either create your own dashboards or import an already customized dashboard from Grafana community. In this guide, we are going to download a dashboard that a user jmutai has customized. All credit goes back to him.

Hence, click the plus (+) on the left panel and select import. After that, copy the ID of the dashboard and paste it as shown in the screenshot below.

Grafana Dashboard ID

After a few, location of the Grafana dashboard to import is updated. Next, select the InfluxDB data source and import the dashboard.

import grafana dashboard

Immediately your dashboard is imported, you should be able to see your dashboards.
