How to Setup PMM(Percona Monitoring and Management) server and Register PMM client on RHEL based system for MongoDB

 In this article we will see how to configure PMM (Percona Monitoring and Management) server and PMM Client setup for MongoDB.

PMM Architecture
Source: https://www.percona.com/

Prerequisites:

1. We need to have Docker 1.12.6 or higher installed.

PMM Server Installation:

1. Pull the image.

   docker pull percona/pmm-server:2
   

2. Create a persistent data container.

   docker create --volume /srv \
   --name pmm-data \
   percona/pmm-server:2 /bin/true

3. Run the image.

   docker run --detach --restart always \
   --publish 443:443 \
   --volumes-from pmm-data \
   --name pmm-server \
   percona/pmm-server:2

           

Devopszones: Create volume

devopszones: PMM server Install

              3. Connect to Percona Monitoring and Management:

https://<IP Address or hostname of your Percona Monitoring and Management Server>/

Default username/password is admin/admin and should be changed on first login.

Install Client

1. Download and install Percona Repo Package

sudo yum install https://repo.percona.com/yum/percona-release-latest.noarch.rpm

2. Install Percona Monitoring and Management Client

sudo yum install pmm2-client

Devopszones: PMM2 client Install

Devopszones: PMM2 Admin Version

Connect Client to Server

Requirements: Client to server communication to secure port on pmm-server (443 assumed) — must be performed on every system to be monitored.

Register Percona Monitoring and Management client with server

sudo pmm-admin config  --server-insecure-tls  --server-url=https://admin:<password>@<PMM Server IP>

Devopszones: PMM2  client Register

MongoDB

Create a Percona Monitoring and Management specific user for monitoring (from the MongoDB CLI)

Enter the MongoDB Console: mongo

use admin

db.createRole({
role: "explainRole",
privileges: [{
resource: {
db: "",
collection: ""
},
actions: [
"listIndexes",
"listCollections",
"dbStats",
"dbHash",
"collStats",
"find"
]
}],
roles:[]
})

db.getSiblingDB("admin").createUser({
user: "pmm",
pwd: "<password>",
roles: [
{ role: "explainRole", db: "admin" },
{ role: "clusterMonitor", db: "admin" },
{ role: "read", db: "local" }
]
})
exit

Register the server for monitoring

sudo pmm-admin add mongodb --username=pmm --password=<password>

Easy-install script

Linux

curl -fsSL -O https://raw.githubusercontent.com/percona/pmm/PMM-2.0/get-pmm.sh -O https://raw.githubusercontent.com/percona/pmm/PMM-2.0/.sha256-oneline && \
sha256sum .sha256-oneline -c && \
chmod +x ./get-pmm.sh && \
./get-pmm.sh
