Skip to content MongoDB Exporter setup is needed to facilitate monitoring and metrics collection for MongoDB deployments. In this post, we will delve into the capabilities of MongoDB Exporter, its installation, configuration, and how it can enhance your MongoDB monitoring experience.
Understanding MongoDB Exporter
MongoDB Exporter serves as a bridge between MongoDB and monitoring systems like Prometheus. It exposes MongoDB metrics in a format that can be readily consumed by these systems, enabling administrators and developers to gain valuable insights into the performance and health of their MongoDB clusters.
Generally, this is installed on the MongoDB server but it is not mandatory. But wherever it is installed MongoDB server should be reachable from it so that it can periodically pull metrics through the rest APIs.
Key Features
- Rich Metrics Collection: MongoDB Exporter collects a variety of metrics, including database connections, query performance, memory usage, and replication statistics.
- Compatibility: It works seamlessly with Prometheus, a widely used open-source monitoring and alerting toolkit.
- Customizable Metrics: You can choose which metrics to collect based on your monitoring requirements.
- Easy Integration: MongoDB Exporter integrates with popular visualization tools like Grafana, allowing you to create insightful dashboards.
Installation
Prerequisites for MongoDB Exporter Setup
- MongoDB instance(s) to monitor
- Prometheus installed and configured
- Install MongoDB through the Ansible script
Main Steps for MongoDB Exporter Setup
Download MongoDB Exporter:
wget https://github.com/percona/mongodb_exporter/releases/download//mongodb_exporter
Make it Executable:
chmod +x mongodb_exporter
Run MongoDB Exporter:
./mongodb_exporter --mongodb.uri=mongodb://localhost:27017
Configuration Options for MongoDB Exporter Setup
MongoDB Exporter provides various configuration options to tailor its behavior:
--mongodb.uri: Connection URI for MongoDB.--web.listen-address: Address on which to expose metrics (default::9216).--web.telemetry-path: Path under which to expose metrics (default:/metrics).--mongodb.tls: Use TLS to connect to MongoDB.
These options allow you to customize MongoDB Exporter according to your deployment specifics.
MongoDB Exporter Setup Integration with Prometheus and Grafana
Configure Prometheus:
Add the following to your Prometheus configuration file (prometheus.yml):
scrape_configs:
- job_name: 'mongodb_exporter'
static_configs:
- targets: ['<server_ip>:9216'] # please replace value of <server_ip> with actual server ip
Configure Grafana:
- Import a MongoDB Exporter dashboard from the Grafana dashboard repository.
- Configure Prometheus as the data source.
Monitor MongoDB using MongoDB Exporter
Once MongoDB Exporter is up and running, you can explore the metrics exposed by accessing the /metrics endpoint. These metrics cover various aspects of your MongoDB deployment, such as connections, memory usage, indexes, and more.
With Prometheus and Grafana, you can create comprehensive dashboards that provide real-time visibility into your MongoDB performance, helping you identify issues and optimize your database configurations.
