MongoDB node by Zabbix agent 2

Overview

The template to monitor single MongoDB server by Zabbix that work without any external scripts. Most of the metrics are collected in one go, thanks to Zabbix bulk data collection.

MongoDB node by Zabbix Agent 2 — collects metrics by polling zabbix-agent2.

Requirements

Zabbix version: 6.4 and higher.

Tested versions

This template has been tested on:

MongoDB 4.0.21, 4.4.3

Configuration

Setup

Setup and configure zabbix-agent2 compiled with the MongoDB monitoring plugin.
Set the {$MONGODB.CONNSTRING} such as <protocol(host:port)> or named session.
Set the user name and password in host macros ({$MONGODB.USER}, {$MONGODB.PASSWORD}) if you want to override parameters from the Zabbix agent configuration file.

Note, depending on the number of DBs and collections discovery operation may be expensive. Use filters with macros {$MONGODB.LLD.FILTER.DB.MATCHES}, {$MONGODB.LLD.FILTER.DB.NOT_MATCHES}, {$MONGODB.LLD.FILTER.COLLECTION.MATCHES}, {$MONGODB.LLD.FILTER.COLLECTION.NOT_MATCHES}.

Test availability: zabbix_get -s mongodb.node -k 'mongodb.ping["{$MONGODB.CONNSTRING}","{$MONGODB.USER}","{$MONGODB.PASSWORD}"]"

MongoDB node by Zabbix agent 2

Overview

For Zabbix version: 6.2 and higher
The template to monitor single MongoDB server by Zabbix that work without any external scripts. Most of the metrics are collected in one go, thanks to Zabbix bulk data collection.

MongoDB node by Zabbix Agent 2 — collects metrics by polling zabbix-agent2.

This template was tested on:

MongoDB, version 4.0.21, 4.4.3

Setup

Setup and configure zabbix-agent2 compiled with the MongoDB monitoring plugin.
Set the {$MONGODB.CONNSTRING} such as <protocol(host:port)> or named session.
Set the user name and password in host macros ({$MONGODB.USER}, {$MONGODB.PASSWORD}) if you want to override parameters from the Zabbix agent configuration file.

Test availability: zabbix_get -s mongodb.node -k 'mongodb.ping["{$MONGODB.CONNSTRING}","{$MONGODB.USER}","{$MONGODB.PASSWORD}"]"

Zabbix configuration

No specific Zabbix configuration is required.

MongoDB node by Zabbix agent 2

Overview

The template to monitor single MongoDB server by Zabbix that work without any external scripts. Most of the metrics are collected in one go, thanks to Zabbix bulk data collection.

MongoDB node by Zabbix Agent 2 — collects metrics by polling zabbix-agent2.

Requirements

Zabbix version: 6.0 and higher.

Tested versions

This template has been tested on:

MongoDB 4.0.21, 4.4.3

Configuration

Setup

Setup and configure zabbix-agent2 compiled with the MongoDB monitoring plugin.
Set the {$MONGODB.CONNSTRING} such as <protocol(host:port)> or named session.
Set the user name and password in host macros ({$MONGODB.USER}, {$MONGODB.PASSWORD}) if you want to override parameters from the Zabbix agent configuration file.

Test availability: zabbix_get -s mongodb.node -k 'mongodb.ping["{$MONGODB.CONNSTRING}","{$MONGODB.USER}","{$MONGODB.PASSWORD}"]"

MongoDB node by Zabbix agent 2

Overview

For Zabbix version: 5.4 and higher
The template to monitor single MongoDB server by Zabbix that work without any external scripts. Most of the metrics are collected in one go, thanks to Zabbix bulk data collection.

MongoDB node by Zabbix Agent 2 — collects metrics by polling zabbix-agent2.

This template was tested on:

MongoDB, version 4.0.21, 4.4.3

Setup

Setup and configure zabbix-agent2 compiled with the MongoDB monitoring plugin.
Set the {$MONGODB.CONNSTRING} such as <protocol(host:port)> or named session.
Set the user name and password in host macros ({$MONGODB.USER}, {$MONGODB.PASSWORD}) if you want to override parameters from the Zabbix agent configuration file.

Test availability: zabbix_get -s mongodb.node -k 'mongodb.ping["{$MONGODB.CONNSTRING}","{$MONGODB.USER}","{$MONGODB.PASSWORD}"]"

Zabbix configuration

No specific Zabbix configuration is required.

Macros used

Template DB MongoDB node by Zabbix Agent 2

Overview

For Zabbix version: 5.0 and higher
The template to monitor single MongoDB server by Zabbix that work without any external scripts. Most of the metrics are collected in one go, thanks to Zabbix bulk data collection.

Template DB MongoDB node by Zabbix Agent 2 — collects metrics by polling zabbix-agent2.

This template was tested on:

MongoDB, version 4.0.21, 4.4.3

Setup

Setup and configure zabbix-agent2 compiled with the MongoDB monitoring plugin.
Set the {$MONGODB.CONNSTRING} such as <protocol(host:port)> or named session.
Set the user name and password in host macros ({$MONGODB.USER}, {$MONGODB.PASSWORD}) if you want to override parameters from the Zabbix agent configuration file.

Test availability: zabbix_get -s mongodb.node -k 'mongodb.ping["{$MONGODB.CONNSTRING}","{$MONGODB.USER}","{$MONGODB.PASSWORD}"]"

Zabbix configuration

No specific Zabbix configuration is required.

MongoDB cluster by Zabbix agent 2

Overview

The template to monitor MongoDB sharded cluster by Zabbix that work without any external scripts. Most of the metrics are collected in one go, thanks to Zabbix bulk data collection.

MongoDB cluster by Zabbix agent 2 — collects metrics from mongos proxy(router) by polling zabbix-agent2.

Requirements

Zabbix version: 6.4 and higher.

Tested versions

This template has been tested on:

MongoDB 4.0.21, 4.4.3

Configuration

Setup

Setup and configure zabbix-agent2 compiled with the MongoDB monitoring plugin.
Set the {$MONGODB.CONNSTRING} such as <protocol(host:port)> or named session of mongos proxy(router).
Set the user name and password in host macros ({$MONGODB.USER}, {$MONGODB.PASSWORD}) if you want to override parameters from the Zabbix agent configuration file.

All sharded Mongodb nodes (mongod) will be discovered with attached template "MongoDB node by Zabbix agent 2".

Test availability: zabbix_get -s mongos.node -k 'mongodb.ping["{$MONGODB.CONNSTRING}","{$MONGODB.USER}","{$MONGODB.PASSWORD}"]"

Feedback

Please report any issues with the template at https://support.zabbix.com

You can also provide feedback, discuss the template or ask for help with it at ZABBIX forums.

This template is for Zabbix version: 6.0

Also available for: 6.4 6.2 5.4 5.0

Source: https://git.zabbix.com/projects/ZBX/repos/zabbix/browse/templates/db/mongodb_cluster?at=release/6.0

MongoDB cluster by Zabbix agent 2

Overview

The template to monitor MongoDB sharded cluster by Zabbix that work without any external scripts. Most of the metrics are collected in one go, thanks to Zabbix bulk data collection.

MongoDB cluster by Zabbix agent 2 — collects metrics from mongos proxy(router) by polling zabbix-agent2.

Requirements

Zabbix version: 6.0 and higher.

Tested versions

This template has been tested on:

MongoDB 4.0.21, 4.4.3

Configuration

Setup

Setup and configure zabbix-agent2 compiled with the MongoDB monitoring plugin.
Set the {$MONGODB.CONNSTRING} such as <protocol(host:port)> or named session of mongos proxy(router).
Set the user name and password in host macros ({$MONGODB.USER}, {$MONGODB.PASSWORD}) if you want to override parameters from the Zabbix agent configuration file.

All sharded Mongodb nodes (mongod) will be discovered with attached template "MongoDB node by Zabbix agent 2".

Test availability: zabbix_get -s mongos.node -k 'mongodb.ping["{$MONGODB.CONNSTRING}","{$MONGODB.USER}","{$MONGODB.PASSWORD}"]"

Macros used

Name	Description	Default
{$MONGODB.CONNSTRING}	Connection string in the URI format (password is not used). This param overwrites a value configured in the "Server" option of the configuration file (if it's set), otherwise, the plugin's default value is used: "tcp://localhost:27017"	`tcp://localhost:27017`
{$MONGODB.USER}	MongoDB username
{$MONGODB.PASSWORD}	MongoDB user password
{$MONGODB.CONNS.AVAILABLE.MIN.WARN}	Minimum number of available connections	`1000`
{$MONGODB.LLD.FILTER.COLLECTION.MATCHES}	Filter of discoverable collections	`.*`
{$MONGODB.LLD.FILTER.COLLECTION.NOT_MATCHES}	Filter to exclude discovered collections	`CHANGE_IF_NEEDED`
{$MONGODB.LLD.FILTER.DB.MATCHES}	Filter of discoverable databases	`.*`
{$MONGODB.LLD.FILTER.DB.NOT_MATCHES}	Filter to exclude discovered databases	`(admin\|config\|local)`
{$MONGODB.CURSOR.TIMEOUT.MAX.WARN}	Maximum number of cursors timing out per second	`1`
{$MONGODB.CURSOR.OPEN.MAX.WARN}	Maximum number of open cursors	`10000`

MongoDB cluster by Zabbix agent 2

Overview

For Zabbix version: 5.4 and higher
The template to monitor MongoDB sharded cluster by Zabbix that work without any external scripts. Most of the metrics are collected in one go, thanks to Zabbix bulk data collection.

MongoDB cluster by Zabbix agent 2 — collects metrics from mongos proxy(router) by polling zabbix-agent2.

This template was tested on:

MongoDB, version 4.0.21, 4.4.3

Setup

Setup and configure zabbix-agent2 compiled with the MongoDB monitoring plugin.
Set the {$MONGODB.CONNSTRING} such as <protocol(host:port)> or named session of mongos proxy(router).
Set the user name and password in host macros ({$MONGODB.USER}, {$MONGODB.PASSWORD}) if you want to override parameters from the Zabbix agent configuration file.

All sharded Mongodb nodes (mongod) will be discovered with attached template "MongoDB node by Zabbix agent 2".

Test availability: zabbix_get -s mongos.node -k 'mongodb.ping["{$MONGODB.CONNSTRING}","{$MONGODB.USER}","{$MONGODB.PASSWORD}"]"

Zabbix configuration

No specific Zabbix configuration is required.
