Day3 ElasticSearch: Install Datadog

Introduction

Datadog is a powerful platform for measuring ElasticSearch.

Recently our team met some issues when we upgrade our ElasticSearch.

With Datadog, we can easily monitor memory, query time and garbage collection.

Today I try to install that.

Unfortunately, it is only free for 14 days…..

Installing Datadog on Ubuntu

Use our easy one-step install.

DD_API_KEY=b96a25a6cf77c77f2ad1292480011aeb bash -c "$(curl -L https://raw.githubusercontent.com/DataDog/datadog-agent/master/cmd/agent/install_script.sh)"

Notice: if you met the problem, it would be proxy issue in apt-get

Datadog Configuration

The configuration files and folders for the Agent are located in:

• /etc/datadog-agent/datadog.yaml

Configuration files for Integrations:

• /etc/datadog-agent/conf.d/

Configure the Agent (conf.yaml + datadog.yaml)

create conf.yaml

Firstly, we just clone the sample file (conf.yaml.example) to our target file (conf.yaml)

cd /etc/datadog-agent/conf.d/elastic.d
sudo cp conf.yaml.example conf.yaml

Configure conf.yaml

in /etc/datadog-agent/conf.d/elastic.d/conf.yam

we set the url, stats, tags and logs.

Configure datadog.yaml

/etc/datadog-agent/datadog.yaml

edit api_key, proxyand logs

Launch the datadog-agent

sudo service datadog-agent start

check the status

sudo datadog-agent status

NOTICE: each time you edit the files, please stop and start again

sudo service datadog-agent stop
sudo service datadog-agent start
sudo service datadog-agent restart
