Elasticsearch

Overview

Elasticsearch is a distributed, open source search and analytics engine for all types of data, including textual, numerical, geospatial, structured, and unstructured. Elasticsearch is built on Apache Lucene and was first released in 2010 by Elasticsearch N.V. (now known as Elastic).

Prerequisites

In order to monitor an Elasticsearch cluster, it must be prepared acccording to Elasticsearch's official documentation: https://www.elastic.co/guide/en/elasticsearch/reference/7.8/monitor-elasticsearch-cluster.html

In order to be able to communicate with the Elasticsearch node's API, the Centreon Poller should access to the port 9200 with the http protocol on the Elasticsearch node.

Installation

Online Licence Business & IT Editions
Offline Licenses
  1. Install the Plugin on all Centreon pollers monitoring Elasticsearch ressources:
yum install centreon-plugin-Applications-Databases-Elasticsearch
  1. Install the Plugin-Pack 'Elasticsearch' in the " Configuration > Plugin Packs" page of the Web Centreon interface
  1. Install the Plugin on all Centreon pollers monitoring Elasticsearch ressources:
yum install centreon-plugin-Applications-Databases-Elasticsearch
  1. Install the Plugin-Pack RPM on the Centreon server Central:
yum install centreon-pack-applications-databases-elasticsearch
  1. In the Configuration > Plugin Packs page of the Web Centreon interface, install the Plugin-Pack 'Elasticsearch'

Host Configuration

Apply the "App-DB-Elasticsearch-custom" template to your newly created host. Then fill the macros value fileds marked as mandatory below:

|Mandatory| Macro | Description | Default value | Example | | :-------| :---------------- --- | :---------------------------------- | :------------ | :------- | | X | ELASTICSEARCHPORT | The Elasticsearch instance port | 9200 | 1234 | | X | ELASTICSEARCHPROTO | The Elasticsearch instance protocol | http | https | | | ELASTICSEARCHUSERNAME | The Elasticsearch instance username | | centreon | | | ELASTICSEARCHPASSWORD | The Elasticsearch instance password | | centreon |

FAQ

How to check in the CLI that the configuration is OK and what are the main options for ?

One the Plugin is installed, you can test it directly in the command line from your Centreon poller with the user centreon-engine:

/usr/lib/centreon/plugins/centreon_elasticsearch.pl \ 
    --hostname=168.253.16.125 \
    --port=9200 \
    --proto=http \
    --plugin=database::elasticsearch::restapi::plugin \
    --mode=node-statistics \
    --filter-name='Node 1'  \
    --username='Elasticsearch_username' \
    --warning-disk-free='20%' \

The command request statistic to the Elasticsearch node named 'Node 1' (--mode=node-statistics --filter-name='Node 1) with the IP/FQDN address 168.253.16.125 (--hostname=168.253.16.125). We will use the port 9200 (--port=9200) and the http protocol (proto=http''). The username of the datebase is Elasticsearch_username (--username='Elasticsearch_username') and its pasword is Elasticsearch_password(--password='Elasticsearch_password'). This command will trigger a WARNING alert if there is less than 20% of free space on the disk (--warning-disk-free='20%'') and a CRITICAL alert if less than 5% (--critical-disk-free='5%'). Some thresholds can also be set on metrics with options "--warning-" and "--critical-".

All the available modes can be listed with the command line:

/usr/lib/centreon/plugins/centreon_elasticsearch.pl \
    --list-mode

And the different mode's options can be displayed with the --help parameter:

/usr/lib/centreon/plugins/centreon_elasticsearch.pl \
    --mode=node-statistics \
    --help

Why do I get the following error:

UNKNOWN: 500 Can't connect

This error message means that the Centreon Plugin couldn't successfully connect to the host API. Check that no third party device (such as a firewall) is blocking the request. A proxy connection may also be necessary to connect to the API. This can be done by using the --proxyurl option in the command.

UNKNOWN: 501 Protocol scheme 'connect' is not supported

When using a proxy to connect to the host, this error message means that the Centreon Plugin library does not support the proxy connection protocol.

In order to prevent this issue, use the curl HTTP backend by adding the following option to the command: --http-backend='curl'.
