Wireguard and GroundWork Integration

Input and output integration overview

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

This plugin writes to a GroundWork Monitor instance, allowing for effective metrics management and monitoring in a centralized manner.

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.

GroundWork

The GroundWork plugin enables Telegraf to send metrics to a GroundWork Monitor instance, specifically supporting GW8 and newer versions. This integration allows users to leverage the robust monitoring capabilities of GroundWork, enabling comprehensive oversight of metrics collected from diverse sources. Users can specify various parameters such as the GroundWork instance URL, agent IDs, and authentication credentials, allowing for a tailored fit within their existing monitoring setups. It also supports secret-store secrets to enhance security for sensitive fields like username and password. Tags used within the plugin provide fine-grained control over how metrics are categorized and displayed within the GroundWork interface, allowing for custom configurations that adapt to different monitoring needs. However, users should be aware that string metrics are currently not supported by GroundWork, impacting how they manage their data.

Configuration

Wireguard

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

GroundWork

[[outputs.groundwork]]
  ## URL of your groundwork instance.
  url = "https://groundwork.example.com"

  ## Agent uuid for GroundWork API Server.
  agent_id = ""

  ## Username and password to access GroundWork API.
  username = ""
  password = ""

  ## Default application type to use in GroundWork client
  # default_app_type = "TELEGRAF"

  ## Default display name for the host with services(metrics).
  # default_host = "telegraf"

  ## Default service state.
  # default_service_state = "SERVICE_OK"

  ## The name of the tag that contains the hostname.
  # resource_tag = "host"

  ## The name of the tag that contains the host group name.
  # group_tag = "group"

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.

GroundWork

1. Centralized Monitoring Dashboard: Use the GroundWork plugin to aggregate metrics from multiple Telegraf instances into a single GroundWork Monitor dashboard. This configuration offers complete visibility into system health across various components, enabling swift identification of performance bottlenecks and improved incident response times.

2. Service Health Monitoring with Alerts: Configure this plugin to send critical service metrics to GroundWork, establishing a robust alerting system. Metrics such as CPU usage and service statuses can trigger alerts based on threshold values, informing administrators of potential issues before they escalate, thereby enhancing system reliability.

3. Historical Data Analysis: Leverage the historical metric capabilities of GroundWork using this plugin to conduct trend analysis over time. This application allows organizations to make data-driven decisions based on comprehensive historical performance metrics, which can assist in capacity planning and optimize resource allocation.

4. Custom Service Tags for Enhanced Monitoring: Extend the functionality of this plugin by utilizing custom tags for different services and hosts. By customizing these tags, users can filter and categorize metrics more effectively within their monitoring framework, leading to tailored monitoring experiences that align specifically with business objectives.
