Apache Zookeeper and Azure Data Explorer Integration

Input and output integration overview

The Zookeeper Telegraf plugin collects and reports metrics from Zookeeper servers, facilitating monitoring and performance analysis. It utilizes the ‘mntr’ command output to gather essential statistics critical for maintaining Zookeeper’s operational health.

The Azure Data Explorer plugin allows integration of metrics collection with Azure Data Explorer, enabling users to analyze and query their telemetry data efficiently. With this plugin, users can configure ingestion settings to suit their needs and leverage Azure’s powerful analytical capabilities.

Integration details

Apache Zookeeper

The Zookeeper plugin for Telegraf is designed to collect vital statistics from Zookeeper servers by executing the ‘mntr’ command. This plugin serves as a monitoring tool that captures important metrics related to Zookeeper’s performance, including connection details, latency, and various operational statistics, facilitating the assessment of the health and efficiency of Zookeeper deployments. In contrast to the Prometheus input plugin, which is recommended when the Prometheus metrics provider is enabled, the Zookeeper plugin accesses raw output from the ‘mntr’ command, rendering it tailored for configurations that do not adopt Prometheus for metrics reporting. This unique approach allows administrators to gather Java Properties formatted metrics directly from Zookeeper, ensuring comprehensive visibility into Zookeeper’s operational state and enabling timely responses to performance anomalies. It specifically excels in environments where Zookeeper operates as a centralized service for maintaining configuration information and names for distributed systems, thus providing immeasurable insights essential for troubleshooting and capacity planning.

Azure Data Explorer

The Azure Data Explorer plugin allows users to write metrics, logs, and time series data collected from various Telegraf input plugins into Azure Data Explorer, Azure Synapse, and Real-Time Analytics in Fabric. This integration serves as a bridge, allowing applications and services to monitor their performance metrics or logs efficiently. Azure Data Explorer is optimized for analytics over large volumes of diverse data types, making it an excellent choice for real-time analytics and monitoring solutions in cloud environments. The plugin empowers users to configure metrics ingestion based on their requirements, define table schemas dynamically, and set various ingestion methods while retaining flexibility regarding roles and permissions needed for database operations. This supports scalable and secure monitoring setups for modern applications that utilize cloud services.

Configuration

Apache Zookeeper

[[inputs.zookeeper]]
  ## An array of address to gather stats about. Specify an ip or hostname
  ## with port. ie localhost:2181, 10.0.0.1:2181, etc.

  ## If no servers are specified, then localhost is used as the host.
  ## If no port is specified, 2181 is used
  servers = [":2181"]

  ## Timeout for metric collections from all servers. Minimum timeout is "1s".
  # timeout = "5s"

  ## Float Parsing - the initial implementation forced any value unable to be
  ## parsed as an int to be a string. Setting this to "float" will attempt to
  ## parse float values as floats and not strings. This would break existing
  ## metrics and may cause issues if a value switches between a float and int.
  # parse_floats = "string"

  ## Optional TLS Config
  # enable_tls = false
  # tls_ca = "/etc/telegraf/ca.pem"
  # tls_cert = "/etc/telegraf/cert.pem"
  # tls_key = "/etc/telegraf/key.pem"
  ## If false, skip chain & host verification
  # insecure_skip_verify = true

Azure Data Explorer

[[outputs.azure_data_explorer]]
  ## The URI property of the Azure Data Explorer resource on Azure
  ## ex: endpoint_url = https://myadxresource.australiasoutheast.kusto.windows.net
  endpoint_url = ""

  ## The Azure Data Explorer database that the metrics will be ingested into.
  ## The plugin will NOT generate this database automatically, it's expected that this database already exists before ingestion.
  ## ex: "exampledatabase"
  database = ""

  ## Timeout for Azure Data Explorer operations
  # timeout = "20s"

  ## Type of metrics grouping used when pushing to Azure Data Explorer.
  ## Default is "TablePerMetric" for one table per different metric.
  ## For more information, please check the plugin README.
  # metrics_grouping_type = "TablePerMetric"

  ## Name of the single table to store all the metrics (Only needed if metrics_grouping_type is "SingleTable").
  # table_name = ""

  ## Creates tables and relevant mapping if set to true(default).
  ## Skips table and mapping creation if set to false, this is useful for running Telegraf with the lowest possible permissions i.e. table ingestor role.
  # create_tables = true

  ##  Ingestion method to use.
  ##  Available options are
  ##    - managed  --  streaming ingestion with fallback to batched ingestion or the "queued" method below
  ##    - queued   --  queue up metrics data and process sequentially
  # ingestion_type = "queued"

Input and output integration examples

Apache Zookeeper

1. Cluster Health Monitoring: Integrate the Zookeeper plugin to monitor the health and performance of a distributed application relying on Zookeeper for configuration management and service discovery. By tracking metrics such as session count, latency, and data size, DevOps teams can identify potential issues before they escalate, ensuring high availability and reliability across applications.

2. Performance Benchmarks: Utilize the plugin to benchmark Zookeeper performance in varying workload scenarios. This not only helps in understanding how Zookeeper behaves under load but also assists in tuning configurations to optimize throughput and reduce latency during peak operations.

3. Alerting for Anomalies: Combine this plugin with alerting tools to create a proactive monitoring system that notifies engineers if specific Zookeeper metrics exceed threshold limits, such as open file descriptor counts or high latency values. This enables teams to respond promptly to issues that could impact service reliability.

4. Historical Data Analysis: Store the metrics collected by the Zookeeper plugin in a time-series database to analyze historical performance trends. This allows teams to evaluate the impact of changes over time, assess the effectiveness of scaling actions, and plan for future capacity needs.

Azure Data Explorer

1. Real-Time Monitoring Dashboard: By integrating metrics from various services into Azure Data Explorer using this plugin, organizations can build comprehensive dashboards that reflect real-time performance metrics. This allows teams to respond proactively to performance issues and optimize system health without delay.

2. Centralized Log Management: Utilize Azure Data Explorer to consolidate logs from multiple applications and services. By utilizing the plugin, organizations can streamline their log analysis processes, making it easier to search, filter, and derive insights from historical data accumulated over time.

3. Data-Driven Alerting Systems: Enhance monitoring capabilities by configuring alerts based on metrics sent via this plugin. Organizations can set thresholds and automate incident responses, significantly reducing downtime and improving the reliability of critical operations.

4. Machine Learning Model Training: By leveraging the data sent to Azure Data Explorer, organizations can perform large-scale analytics and prepare the data for feeding into machine learning models. This plugin enables the structuring of data that can subsequently be used for predictive analytics, leading to enhanced decision-making capabilities.
