Wireguard and MongoDB Integration

Input and output integration overview

This plugin collects and reports statistics from the local Wireguard server, providing insights into its interfaces and peers.

The MongoDB Telegraf Plugin enables users to send metrics to a MongoDB database, automatically managing time series collections.

Integration details

Wireguard

The Wireguard plugin collects statistics on the local Wireguard server using the wgctrl library. It reports gauge metrics for Wireguard interface device(s) and its peers. This enables monitoring of various parameters related to Wireguard functionality, enhancing an administrator’s capability to assess the performance and status of their Wireguard setup. The metrics collected can lead to proactive management of the network interfaces, aiding in detecting and resolving issues before they impact service availability.

MongoDB

This plugin sends metrics to MongoDB and seamlessly integrates with its time series functionality, allowing for automatic creation of collections as time series when they don’t already exist. It requires MongoDB version 5.0 or higher to utilize the time series collections feature, which is vital for efficiently storing and querying time-based data. This plugin enhances the monitoring capabilities by ensuring that all relevant metrics are stored and organized correctly within MongoDB, providing users the ability to leverage MongoDB’s powerful querying and aggregation features for time series analysis.

Configuration

Wireguard

[[inputs.wireguard]]
  ## Optional list of Wireguard device/interface names to query.
  ## If omitted, all Wireguard interfaces are queried.
  # devices = ["wg0"]

MongoDB

[[outputs.mongodb]]
              # connection string examples for mongodb
              dsn = "mongodb://localhost:27017"
              # dsn = "mongodb://mongod1:27017,mongod2:27017,mongod3:27017/admin&replicaSet=myReplSet&w=1"

              # overrides serverSelectionTimeoutMS in dsn if set
              # timeout = "30s"

              # default authentication, optional
              # authentication = "NONE"

              # for SCRAM-SHA-256 authentication
              # authentication = "SCRAM"
              # username = "root"
              # password = "***"

              # for x509 certificate authentication
              # authentication = "X509"
              # tls_ca = "ca.pem"
              # tls_key = "client.pem"
              # # tls_key_pwd = "changeme" # required for encrypted tls_key
              # insecure_skip_verify = false

              # database to store measurements and time series collections
              # database = "telegraf"

              # granularity can be seconds, minutes, or hours.
              # configuring this value will be based on your input collection frequency.
              # see https://docs.mongodb.com/manual/core/timeseries-collections/#create-a-time-series-collection
              # granularity = "seconds"

              # optionally set a TTL to automatically expire documents from the measurement collections.
              # ttl = "360h"

Input and output integration examples

Wireguard

1. Network Performance Monitoring: Monitor the performance metrics of your Wireguard interfaces, allowing you to track bandwidth usage and identify potential bottlenecks in real-time. By integrating these statistics into your existing monitoring system, network administrators can gain insights into the efficiency of their VPN configuration and make data-driven adjustments.

2. Peer Health Checks: Implement health checks for Wireguard peers by monitoring the last handshake time and traffic metrics. If a peer shows a significant drop in RX/TX bytes or hasn’t completed a handshake in a timely manner, alerts can be triggered to address potential connectivity issues proactively.

3. Dynamic Resource Allocation: Use the metrics collected by the Wireguard plugin to dynamically allocate or adjust network resources based on current bandwidth usage and peer activity. For instance, when a peer is heavily utilized, administrators can respond by allocating additional resources or adjusting configurations to optimize performance accordingly.

4. Historical Data Analysis: Aggregate data over time to analyze historical trends in Wireguard device performance. By storing these metrics in a time-series database, teams can visualize long-term trends, assess the impact of configuration changes, and drive strategic decisions regarding network management.

MongoDB

1. Dynamic Logging to MongoDB for IoT Devices: Utilize this plugin to collect and store metrics from a fleet of IoT devices in real-time. By sending device logs directly to MongoDB, you can create a centralized database that allows for easy access and querying of health metrics and performance data, enabling proactive maintenance and troubleshooting based on historical trends.

2. Time Series Analysis of Web Traffic: Use the MongoDB Telegraf Plugin to gather and analyze web traffic metrics over time. This application can help you understand peak usage times, user interactions, and behavior patterns, which can guide marketing strategies and infrastructure scaling decisions for improved user experience.

3. Automated Monitoring and Alerting System: Integrate the MongoDB plugin into an automated monitoring system that tracks application performance metrics. With time series collections, you can set up alerts based on specific thresholds, allowing your team to respond to potential issues before they affect users. This proactive management can enhance service reliability and overall performance.

4. Data Retention and TTL Management in Metrics Storage: Leverage the TTL feature for documents within MongoDB collections to auto-expire outdated metrics. This is particularly useful for environments where only recent performance data is relevant, preventing your MongoDB database from becoming cluttered with old metrics and ensuring efficient data management.
