Junos Telemetry Interface

Junos Telemetry Interface (JTI) is a push mechanism to collect operational metrics for monitoring the health of a network that has no scaling limitations. 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 JTI OpenConfig Telemetry metrics to Logz.io, you need to add the inputs.jti_openconfig_telemetry 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-1.27.3_windows_amd64.zip

After downloading the archive, extract its content 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.jti_openconfig_telemetry plug-in​

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

[[inputs.jti_openconfig_telemetry]]
  ## Type of JTI OpenConfig Telemetry-IP interface.
  ## Can be either "tunnel" or "router".
  # service_type = "tunnel"

  ## Address of the JTI OpenConfig Telemetry-IP interface.
  service_address = "localhost:3671"

  ## Measurement definition(s)
  # [[inputs.jti_openconfig_telemetry.measurement]]
  #   ## Name of the measurement
  #   name = "temperature"
  #   ## Datapoint-Type (DPT) of the JTI OpenConfig Telemetry messages
  #   dpt = "9.001"
  #   ## List of Group-Addresses (GAs) assigned to the measurement
  #   addresses = ["5/5/1"]

  # [[inputs.jti_openconfig_telemetry.measurement]]
  #   name = "illumination"
  #   dpt = "9.004"
  #   addresses = ["5/5/3"]
note

The database name is only required for instantiating a connection with the server and does not restrict the databases that we collect metrics from. 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 <<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.
  • Replace <<PROMETHEUS-METRICS-SHIPPING-TOKEN>> with a token for the Metrics account you want to ship to. Look up your Metrics token.

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.
