IPVS and Azure Application Insights Integration

Input and output integration overview

The IPVS plugin is designed to collect metrics related to IPVS virtual and real servers on Linux systems.

This plugin writes Telegraf metrics to Azure Application Insights, enabling powerful monitoring and diagnostics.

Integration details

IPVS

The IPVS plugin gathers metrics about IPVS virtual and real servers using the Linux kernel netlink socket interface. As a component specifically designed for Linux, it tracks performance related to IP virtual servers, allowing users to monitor various attributes such as active connections, packet statistics, and byte counts. Key metrics include those for both virtual and real servers, facilitating a comprehensive view of server performance. The plugin also requires the Telegraf process to run with appropriate permissions, typically as root or a user with specific capabilities for proper operation.

Azure Application Insights

The Azure Application Insights plugin integrates Telegraf with Azure’s Application Insights service, facilitating the seamless transmission of metrics from various sources to a centralized monitoring platform. This plugin empowers users to harness the capabilities of Azure Application Insights, a powerful application performance management tool, allowing developers and IT operations teams to gain valuable insights into the performance, availability, and usage of their applications. By employing this plugin, users can monitor application telemetry and operational data efficiently, contributing to better diagnostics and improved application performance.

Key features of this plugin include the ability to specify an instrumentation key for the Application Insights resource, configure the endpoint URL for tracking, and enable additional diagnostic logging for a more comprehensive analysis. Furthermore, the plugin provides context tagging capabilities, allowing the addition of specific Application Insights context tags to enhance the contextual information associated with metrics being sent. These features collectively make the Azure Application Insights Output Plugin a vital tool for organizations looking to optimize their monitoring capabilities within Azure.

Configuration

IPVS

[[inputs.ipvs]]
  # no configuration

Azure Application Insights

[[outputs.application_insights]]
  ## Instrumentation key of the Application Insights resource.
  instrumentation_key = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxx"

  ## Regions that require endpoint modification https://docs.microsoft.com/en-us/azure/azure-monitor/app/custom-endpoints
  # endpoint_url = "https://dc.services.visualstudio.com/v2/track"

  ## Timeout for closing (default: 5s).
  # timeout = "5s"

  ## Enable additional diagnostic logging.
  # enable_diagnostic_logging = false

  ## NOTE: Due to the way TOML is parsed, tables must be at the END of the
  ## plugin definition, otherwise additional config options are read as part of
  ## the table

  ## Context Tag Sources add Application Insights context tags to a tag value.
  ##
  ## For list of allowed context tag keys see:
  ## https://github.com/microsoft/ApplicationInsights-Go/blob/master/appinsights/contracts/contexttagkeys.go
  # [outputs.application_insights.context_tag_sources]
  #   "ai.cloud.role" = "kubernetes_container_name"
  #   "ai.cloud.roleInstance" = "kubernetes_pod_name"

Input and output integration examples

IPVS

1. Load Balancing Performance Monitoring: Use the IPVS plugin to monitor the performance of a load balancing setup in a Linux environment where IPVS is implemented. By collecting metrics such as byte counts, packet rates, and active connections, administrators can gain real-time insights into server performance, allowing for proactive adjustments to load distribution strategies and ensuring that no individual server becomes a bottleneck.

2. Automated Alerting for Connection Thresholds: Integrate the metrics collected by the IPVS plugin with an alerting system to automatically notify administrators when active connections exceed or fall below specified thresholds. This use case enables dynamic scaling of backend resources, optimizing application performance and resource utilization, while minimizing the risk of sudden service disruptions.

3. Historical Performance Trend Analysis: Store the metrics gathered by the IPVS plugin in a time-series database for historical analysis. By analyzing trends over time, organizations can identify patterns in server performance, correlate them with application usage spikes, and make informed decisions regarding infrastructure upgrades or maintenance schedules to better handle peak loads.

Azure Application Insights

1. Application Performance Monitoring: Utilize the Azure Application Insights plugin to continuously monitor the performance of your web applications or microservices. By sending Telegraf metrics directly to Application Insights, teams can visualize real-time application performance data, enabling proactive tuning and optimization of application resources. This setup not only enhances the reliability of applications but also ensures user satisfaction through consistent performance monitoring.

2. Integrated Logging and Telemetry: Combine this plugin with centralized logging solutions to provide a comprehensive observability stack. By sending telecom data to Azure Application Insights, teams can correlate performance metrics with log data and gain deeper insights into application behavior, allowing for more efficient troubleshooting and root cause analysis.

3. Contextual Monitoring of Cloud Resources: Use the context tagging feature to enrich your application metrics with specific contextual information related to your cloud environment. This enhanced context can be invaluable for understanding the performance of cloud-native applications, enabling better scaling decisions and resource management based on real usage patterns.

4. Real-time Alerts Setup: Configure Application Insights to trigger alerts based on specific metrics received via this plugin. This allows teams to be notified of performance degradation or anomalies in real-time, enabling immediate action to mitigate issues and maintain high availability of applications.
