# MongoDB cluster by Zabbix agent 2

## Overview

For Zabbix version: 6.2 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

> See [Zabbix template operation](https://www.zabbix.com/documentation/6.2/manual/config/templates_out_of_the_box/zabbix_agent2) for basic instructions.

1. Setup and configure zabbix-agent2 compiled with the MongoDB monitoring plugin.
2. Set the {$MONGODB.CONNSTRING} such as <protocol(host:port)> or named session of mongos proxy(router).
3. Set the user name and password in host macros ({$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}.

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.

### Macros used

|Name|Description|Default|
|----|-----------|-------|
|{$MONGODB.CONNS.AVAILABLE.MIN.WARN} |<p>Minimum number of available connections</p> |`1000` |
|{$MONGODB.CONNSTRING} |<p>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"</p> |`tcp://localhost:27017` |
|{$MONGODB.CURSOR.OPEN.MAX.WARN} |<p>Maximum number of open cursors</p> |`10000` |
|{$MONGODB.CURSOR.TIMEOUT.MAX.WARN} |<p>Maximum number of cursors timing out per second</p> |`1` |
|{$MONGODB.LLD.FILTER.COLLECTION.MATCHES} |<p>Filter of discoverable collections</p> |`.*` |
|{$MONGODB.LLD.FILTER.COLLECTION.NOT_MATCHES} |<p>Filter to exclude discovered collections</p> |`CHANGE_IF_NEEDED` |
|{$MONGODB.LLD.FILTER.DB.MATCHES} |<p>Filter of discoverable databases</p> |`.*` |
|{$MONGODB.LLD.FILTER.DB.NOT_MATCHES} |<p>Filter to exclude discovered databases</p> |`(admin|config|local)` |
|{$MONGODB.PASSWORD} |<p>MongoDB user password</p> |`` |
|{$MONGODB.USER} |<p>MongoDB username</p> |`` |
