Overview

Telegraf is a plug-in driven server agent for collecting and sending metrics and events from databases, systems and IoT sensors.

To send your Prometheus-format Apache Aurora metrics to Logz.io, you need to add the inputs.aurora and outputs.http plug-ins to your Telegraf configuration file.

Configuring Telegraf to send your metrics data to Logz.io

Set up Telegraf v1.17 or higher
For Windows:
wget https://dl.influxdata.com/telegraf/releases/telegraf-1.19.2_windows_amd64.zip

After downloading the archive, extract its contents into C:\Program Files\Logzio\telegraf\.

The configuration file is located at C:\Program Files\Logzio\telegraf\.

For MacOS:
brew install telegraf

The configuration file is located at /usr/local/etc/telegraf.conf.

For Linux:

Ubuntu & Debian

sudo apt-get update && sudo apt-get install telegraf

The configuration file is located at /etc/telegraf/telegraf.conf.

RedHat and CentOS

sudo yum install telegraf

The configuration file is located at /etc/telegraf/telegraf.conf.

SLES & openSUSE

# add go repository
zypper ar -f obs://devel:languages:go/ go
# install latest telegraf
zypper in telegraf

The configuration file is located at /etc/telegraf/telegraf.conf.

FreeBSD/PC-BSD

sudo pkg install telegraf

The configuration file is located at /etc/telegraf/telegraf.conf.

Add the inputs.aurora plug-in

First you need to configure the input plug-in to enable Telegraf to scrape the Apache Aurora data from your hosts. To do this, add the following code to the configuration file:

[[inputs.aurora]]
  ## Schedulers are the base addresses of your Aurora Schedulers
  schedulers = ["http://127.0.0.1:8081"]

  ## Set of role types to collect metrics from.
  ##
  ## The scheduler roles are checked each interval by contacting the
  ## scheduler nodes; zookeeper is not contacted.
  # roles = ["leader", "follower"]

  ## Timeout is the max time for total network operations.
  # timeout = "5s"

  ## Username and password are sent using HTTP Basic Auth.
  # username = "username"
  # password = "pa$$word"

  ## Optional TLS Config
  # tls_ca = "/etc/telegraf/ca.pem"
  # tls_cert = "/etc/telegraf/cert.pem"
  # tls_key = "/etc/telegraf/key.pem"
  ## Use TLS but skip chain & host verification
  # insecure_skip_verify = false

The full list of data scraping and configuring options can be found here

Add the outputs.http plug-in

After you create the configuration file, configure the output plug-in to enable Telegraf to send your data to Logz.io in Prometheus-format. To do this, add the following code to the configuration file:

[[outputs.http]]
  url = "https://<<LISTENER-HOST>>:8053"
  data_format = "prometheusremotewrite"
  [outputs.http.headers]
     Content-Type = "application/x-protobuf"
     Content-Encoding = "snappy"
     X-Prometheus-Remote-Write-Version = "0.1.0"
     Authorization = "Bearer <<PROMETHEUS-METRICS-SHIPPING-TOKEN>>"

Replace the placeholders to match your specifics. (They are indicated by the double angle brackets << >>):

  • Replace <<PROMETHEUS-METRICS-SHIPPING-TOKEN>> with a token for the Metrics account you want to ship to.
    Here’s how to look up your Metrics token.
  • Replace <<LISTENER-HOST>> with the Logz.io Listener URL for your region, configured to use port 8052 for http traffic, or port 8053 for https traffic. For example, listener.logz.io if your account is hosted on AWS US East, or listener-nl.logz.io if hosted on Azure West Europe.
Start Telegraf
On Windows:
telegraf.exe --service start
On MacOS:
telegraf --config telegraf.conf
On Linux:

Linux (sysvinit and upstart installations)

sudo service telegraf start

Linux (systemd installations)

systemctl start telegraf
Check Logz.io for your metrics

Give your data some time to get from your system to ours, then log in to your Logz.io Metrics account, and open the Logz.io Metrics tab.
