Apache ZooKeeper

Apache ZooKeeper is an open-source server for highly reliable distributed coordination of cloud applications. 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 Zookeper metrics to Logz.io, you need to add the inputs.zookeper and outputs.http plug-ins to your Telegraf configuration file.

Configure Telegraf to send metrics data to Logz.io​

Set up Telegraf v1.17 or higher on each Zookeeper machine​

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.zookeper plug-in​

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

[[inputs.zookeper]]
  ## An array of address to gather stats about. Specify an ip or hostname
  ## with port. ie localhost:2181, 10.0.0.1:2181, etc.

  ## If no servers are specified, then localhost is used as the host.
  ## If no port is specified, 2181 is used
  servers = [":2181"]

  ## Timeout for metric collections from all servers.  Minimum timeout is "1s".
  # timeout = "5s"

  ## Optional TLS Config
  # enable_tls = true
  # 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
note

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.

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.
