MongoDB

StackGen's [Kubernetes agent](../../Collecting Telemetry/Install the OpsVerse Agent#VEqXM) can be used to collect metrics from MongoDB

Kubernetes​

Add the following YAML snippet to the agent's values.yaml and run the agent based on these [instructions](../../Collecting Telemetry/Install the OpsVerse Agent#VEqXM).

mongodb-exporter:
  enabled: true
  annotations:
    prometheus.io/scrape: "true"

  # Option A:
  # [mongodb[+srv]://][user:pass@]host1[:port1][,host2[:port2],...][/database][?options]
  mongodb:
    uri: ""

  # (or) Alternatively, Option B:
  # Name of an externally managed secret (in the same namespace) containing the connection uri as key `mongodb-uri`.
  # If this is provided, the value mongodb.uri is ignored.
  existingSecret:
    name: ""
    key: "mongodb-uri"

MongoDB Atlas​

To configure an Atlas integration with Prometheus, follow the steps below:

  • Complete the procedure given in the MongoDB documentaion
  • After the setup, a generated snippet is provided. Copy and store it securely and replace the username, password and the url in the below snippet.

Add the following YAML snippet to the agent's values.yaml and run the agent based on these [instructions](../../Collecting Telemetry/Install the OpsVerse Agent#VEqXM).

- job_name: "<job_name>"
  scrape_interval: 10s
  metrics_path: /metrics
  scheme : https
  basic_auth:
    username: <username>
    password: <password>
  http_sd_configs:
    - url: https://cloud.mongodb.com/prometheus/v1.0/groups/<placeholder>/discovery
      basic_auth:
        username: <username>
        password: <password>

MongoDB​

Add the following YAML snippet to the agent's values.yaml and run the agent based on these [instructions](../../Collecting Telemetry/Install the OpsVerse Agent#VEqXM).

mongodb-exporter:
  enabled: true
  annotations:
    prometheus.io/scrape: "true"

  # Option A:
  # [mongodb[+srv]://][user:pass@]host1[:port1][,host2[:port2],...][/database][?options]
  mongodb:
    uri: ""

  # (or) Alternatively, Option B:
  # Name of an externally managed secret (in the same namespace) containing the connection uri as key `mongodb-uri`.
  # If this is provided, the value mongodb.uri is ignored.
  existingSecret:
    name: ""
    key: "mongodb-uri"

Single Machine​

Alternatively, you can install the Prometheus MongoDB exporter on a single machine.

Prerequisite(s):

  • you have the [StackGen Agent running on the machine](../../Collecting Telemetry/Install the OpsVerse Agent#dszlx).

Run this command to install the MongoDB exporter as a systemd unit:

# For amd64
curl https://raw.githubusercontent.com/OpsVerseIO/installers/main/prometheus-exporters/install-exporter-amd64.sh | sudo bash -s -- -e mongodb

# For arm64
curl https://raw.githubusercontent.com/OpsVerseIO/installers/main/prometheus-exporters/install-exporter-arm64.sh | sudo bash -s -- -e mongodb
  • The agent will begin scraping the metrics automatically; the script will drop the scrape target into /etc/opsverse/targets/, so the agent will begin automatically scraping
  • If you need to update MongoDB connection info, after you install, you may edit /etc/systemd/system/prom-mongodb-exporter.service with the appropriate CLI args you want, and then restart the service:
