Overview

Aerospike is a flash-optimized and in-memory open source distributed key value NoSQL database. 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 Aerospike metrics to Logz.io, you need to add the inputs.aerospike 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 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.

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.aerospike plug-in

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

[[inputs.aerospike]]
  ## Aerospike servers to connect to (with port)
  ## This plugin will query all namespaces the aerospike
  ## server has configured and get stats for them.
  servers = ["localhost:3000"]

  # username = "telegraf"
  # password = "pa$$word"

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

  # Feature Options
  # Add namespace variable to limit the namespaces executed on
  # Leave blank to do all
  # disable_query_namespaces = true # default false
  # namespaces = ["namespace1", "namespace2"]

  # Enable set level telemetry
  # query_sets = true # default: false
  # Add namespace set combinations to limit sets executed on
  # Leave blank to do all sets
  # sets = ["namespace1/set1", "namespace1/set2", "namespace3"]

  # Histograms
  # enable_ttl_histogram = true # default: false
  # enable_object_size_linear_histogram = true # default: false

  # by default, aerospike produces a 100 bucket histogram
  # this is not great for most graphing tools, this will allow
  # the ability to squash this to a smaller number of buckets
  # To have a balanced histogram, the number of buckets chosen 
  # should divide evenly into 100.
  # num_histogram_buckets = 100 # default: 10

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.
