Apache ZooKeeper Metrics

Collect and ship Apache ZooKeeper server metrics to Logstash and Elasticsearch.

Metricbeat is a lightweight shipper that helps you monitor your Apache ZooKeeper servers by collecting metrics running on the Apache ZooKeeper server. Configure Metricbeat using the pre-defined examples below to collect and ship Apache ZooKeeper logs & service metrics and statistics to Logstash or Elasticsearch.

Step 1 - Install MetricbeatCopy

deb (Debian/Ubuntu/Mint)

curl -L -O https://artifacts.elastic.co/downloads/beats//-oss-7.8.1-amd64.deb
sudo dpkg -i -oss-7.8.1-amd64.deb

rpm (CentOS/RHEL/Fedora)

curl -L -O https://artifacts.elastic.co/downloads/beats//-oss-7.8.1-x86_64.rpm
sudo rpm -vi -oss-7.8.1-x86_64.rpm

macOS

curl -L -O https://artifacts.elastic.co/downloads/beats//-oss-7.8.1-darwin-x86_64.tar.gz
tar xzvf -oss-7.8.1-darwin-x86_64.tar.gz

Windows

  • Download the Windows zip file from the official downloads page.
  • Extract the contents of the zip file into C:\Program Files.
  • Rename the -<version>-windows directory to ``.
  • Open a PowerShell prompt as an Administrator (right-click the PowerShell icon and select Run As Administrator). If you are running Windows XP, you may need to download and install PowerShell.
  • Run the following commands to install as a Windows service:
cd 'C:\Program Files\'
.\install-service-.ps1
If script execution is disabled on your system, you need to set the execution policy for the current session to allow the script to run. For example: PowerShell.exe -ExecutionPolicy UnRestricted -File .\install-service-.ps1.
My OS isn't here! Don't see your system? Check out the official downloads page for more options (including 32-bit versions).

Step 2 - Locate configuration fileCopy

/etc/metricbeat/metricbeat.yml

Step 3 - Configure outputCopy

We'll be shipping to Logstash so that we have the option to run filters before the data is indexed.
Comment out the elasticsearch output block.

## Comment out elasticsearch output
#output.elasticsearch:
#  hosts: ["localhost:9200"]
No input available! Your stack is missing the required input for this data source Talk to support to add the input

Step 4 - Validate configurationCopy

Let's check the configuration file is syntactically correct by running directly inside the terminal. If the file is invalid, will print an error loading config file error message with details on how to correct the problem.

deb/rpm

sudo  -e -c /etc//.yml

macOS

cd <EXTRACTED_ARCHIVE>
./ -e -c .yml

Windows

cd <EXTRACTED_ARCHIVE>
.\.exe -e -c .yml

Step 5 - Enable moduleCopy

There are several built in metricbeat modules you can use. To enable the Apache ZooKeeper module, run the following:

metricbeat modules list
metricbeat modules enable zookeeper

Step 6 - Configure moduleCopy

Each module has its own configuration file where different metricsets can be enabled / disabled. Locate the configuration file for the Apache ZooKeeper module.

/etc/metricbeat/modules.d/zookeeper.yml

By default the following metricsets are disabled. To enable or disable a metric simply comment or uncomment the line out.

- module: zookeeper
 # metricsets:
   # - mntr
   # - server
  period: 10s
  hosts: ["localhost:2181"]

Step 7 - Start MetricbeatCopy

Ok, time to start gathering metrics!

sudo systemctl enable metricbeat
sudo systemctl start metricbeat

Step 8 - CompatibilityCopy

The Apache ZooKeeper metricsets were tested with Apache ZooKeeper 3.4.8 and are expected to work with all versions >= 3.4.0. Versions prior to 3.4 do not support the mntr command.
