Discussion thread for official Zabbix Template DB MongoDB

[AlexL]

This thread is designed to provide grounds for discussion of the official Zabbix Template for MongoDB .
The template and details of the template will soon be available in GIT repository.

Zabbix is always looking for ways to improve our services and to make our users happier.
We pride ourselves on doing our best each and every day, but we know that there is always something more to learn.
We would like to hear back from you to know what have you liked and what would you improve in the template.

Hi Alex,

Do you think you will code the SSL encryption for MongoDB ?
Even with current MongoDB version (5.0.2), it is not possible to disable encryption for loopback ... as the requests come from Agent2 locally installed on the MongoDB Server.

Thanks, Alain

Hi

Is there any way to use a database other than 'admin' for authentication?

Hello,

What can be done to make it works for MongoDB version 5 ?
I suppose the first step will be to update the Mongo driver and recompile the agent ?

Best regards,
Georgi

Hi,
This is the classical template. I'm asking about the Go driver used in the Agent2

Hi,
is it possible remove authentication from key names (Zabbix raw items - i.e. mongodb.oplog.stats["{$MONGODB.CONNSTRING}","{$MONGODB.USER}","{$MONGO DB.PASSWORD}"] )?

Change Macro Value to "Secret text"

What rights are needed to use MongoDB plugin?

There should be a document stating the exact rights the mongodb plugin needs to operate. For an example look at the mysql plugin.

[Georgi]

Hi,
the used Mongo commands are in the Go plugin folder (zabbix-6.0.4.tar\zabbix-6.0.4\src\go\plugins\mongodb) in Agent2 ( Zabbix source file)
Doing a quick search the commands are
collStats, top, connPoolStats, dbStats ,replSetGetConfig, and serverStatus
Your monitoring user should be able to execute them .

[gelowe]

Doing more research it seems the Role clusterMonitor has all the rights needed

So ppl just need to add a user with these rights , example creating account zabbix_mon with password of bad-paasword

use admin
db.createUser(
{
user: "zabbix_mon",
pwd: "bad-password",
roles: [ { role: "clusterMonitor", db: "admin" } ]
}
)

• I'm getting
  "Unknown metric mongodb.server.status"
  
  What should I do?

[bugrakeskin]

Hi,

If you struggle with scram-sha-256 ;

db.createUser(
{
user: "zabbix",
pwd: "password",
roles: [ { role: "monitor", db: "admin" } ],
mechanisms : ["SCRAM-SHA-1","SCRAM-SHA-256"]
}
)​

::: Zabbix 6.0 LTS - i have a mongo cluster , 1 primary and 2 slaves.

Problem : I can get data only i restart the agent2 on mongodb.

What i did:

MongoDB side ;

User created with root priviledges(for testing)
agent2 is installed.
agent2 is active&passive working without errors.

Zabbix side;

MongoDB server is created in the GUI. >> Mongodb Temp. for agent2 is added. >> The Macros is filled with | user name , password and tcp:\\xxx-port

When i restart the agent2 i can see the data is coming but only one time. No refreshing.

Am i doing something wrong?

Thank you.

Zabbix 6.0 LTS
MongoDB 6 - 3 node cluster

Problem : items do not work (Items are disabled by default, I enabled them)
Unhealthy replicas
Number of unhealthy replicas

Reported error example on SECONDARY node:
"Preprocessing failed for: {"$clusterTime":{"clusterTime":{"T":1689660301, "I" :20},"signature":{"hash":{"Subtype":0,"Data":"2...
1. Failed: cannot extract value from json by path "$.members[?(@.self == "true")].unhealthyNodes.first()": no data matches the specified path"

Posible fix for Unhealthy replicas:
"$.members[?(@.health == 0)].name" code is working for me.

Feel free to check templates
Thank you.

Yup, same error here!
I've just made theses fixes in my "MongoDB node by Zabbix agent 2" template:

• Item "MongoDB: Unhealthy replicas"
  Preprocessing > JSONPath :

  $.members[?(@.health == 0)].name

• Item "MongoDB: Number of unhealthy replicas"
  Preprocessing > JSONPath :

  $.members[?(@.health == 0)].length()

Hi, I'm trying to monitor my mongo db from scratch.

First apply the MongoDB node by Zabbix agent 2 template, then Install and configure zabbix-agent2 compiled with the MongoDB monitoring plugin. creating a file called mongo.conf and there indicating the variable Plugins.MongoDB.System.Pat with the path of the mongo executable, then perform the include in the zabbix.conf indicating the path of the mongo.conf, following everything from this resource: Monitorización e integración de Mongodb con Zabbix

Also create the zabbix monitor user in mongo with its readAnyDatabase and clusterMonitor role. to validate that everything is in order, I execute this instruction mongodb.ping[tcp://127.0.0.1,user,password] on my host mongodb receiving the following:
zabbix_get [25684]: Get value error: cannot resolve [mongodb.node]

Could someone help me with the installation, if I'm correct.
