Mesos and Graylog Integration

Input and output integration overview

This input plugin gathers metrics from Mesos.

The Graylog plugin allows you to send Telegraf metrics to a Graylog server, utilizing the GELF format for structured logging.

Integration details

Mesos

The Mesos plugin for Telegraf is designed to collect and report metrics from Apache Mesos clusters, which is essential for monitoring and observability in container orchestration and resource management. Mesos, known for its scalability and ability to manage diverse workloads, generates various metrics about resource usage, tasks, frameworks, and overall system performance. By utilizing this plugin, users can track the health and efficiency of their Mesos clusters, gather insights into resource distribution, and ensure that applications receive the necessary resources in a timely manner. The configuration allows users to specify the relevant Mesos master’s details, along with the desired metric groups to collect, making it adaptable to different deployments and monitoring needs. Overall, this plugin integrates seamlessly within the Telegraf collection pipeline, supporting detailed observability for cloud-native environments.

Graylog

The Graylog plugin is designed for sending metrics to a Graylog instance using the GELF (Graylog Extended Log Format) format. GELF helps standardize the logging data, making it easier for systems to send and analyze logs. The plugin adheres to the GELF specification, which lays out requirements for specific fields within the payload. Notably, the timestamp must be in UNIX format, and if present, the plugin sends the timestamp as-is to Graylog without alterations. If omitted, it automatically generates a timestamp. Additionally, any extra fields not explicitly defined by the spec will be prefixed with an underscore, helping to keep the data organized and compliant with GELF’s requirements. This capability is particularly valuable for users monitoring applications and infrastructure in real-time, as it allows for seamless integration and improved visibility across multiple systems.

Configuration

Mesos

[[inputs.mesos]]
  ## Timeout, in ms.
  timeout = 100

  ## A list of Mesos masters.
  masters = ["http://localhost:5050"]

  ## Master metrics groups to be collected, by default, all enabled.
  master_collections = [
    "resources",
    "master",
    "system",
    "agents",
    "frameworks",
    "framework_offers",
    "tasks",
    "messages",
    "evqueue",
    "registrar",
    "allocator",
  ]

  ## A list of Mesos slaves, default is []
  # slaves = []

  ## Slave metrics groups to be collected, by default, all enabled.
  # slave_collections = [
  #   "resources",
  #   "agent",
  #   "system",
  #   "executors",
  #   "tasks",
  #   "messages",
  # ]

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

Graylog

[[outputs.graylog]]
  ## Endpoints for your graylog instances.
  servers = ["udp://127.0.0.1:12201"]

  ## Connection timeout.
  # timeout = "5s"

  ## The field to use as the GELF short_message, if unset the static string
  ## "telegraf" will be used.
  ##   example: short_message_field = "message"
  # short_message_field = ""

  ## According to GELF payload specification, additional fields names must be prefixed
  ## with an underscore. Previous versions did not prefix custom field 'name' with underscore.
  ## Set to true for backward compatibility.
  # name_field_no_prefix = false

  ## Connection retry options
  ## Attempt to connect to the endpoints if the initial connection fails.
  ## If 'false', Telegraf will give up after 3 connection attempt and will
  ## exit with an error. If set to 'true', the plugin will retry to connect
  ## to the unconnected endpoints infinitely.
  # connection_retry = false
  ## Time to wait between connection retry attempts.
  # connection_retry_wait_time = "15s"

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

Input and output integration examples

Mesos

1. Resource Utilization Monitoring: Use the Mesos plugin to continually monitor CPU, memory, and disk usage across your Mesos cluster. For a rapidly scaling application, tracking these metrics helps ensure that resources are dynamically allocated according to workloads, preventing bottlenecks and optimizing performance.

2. Framework Performance Analysis: Integrate this plugin to measure the performance of different frameworks running on Mesos. By comparing active frameworks and their task success rates, you can identify which frameworks provide the best resource efficiency or may require optimization.

3. Alerts for System Health: Set up alerts based on metrics collected by the Mesos plugin to notify engineering teams when resource utilization exceeds key thresholds or when specific tasks fail. This allows for proactive intervention and maintenance before critical failures occur.

4. Capacity Planning: Utilize gathered metrics to analyze historical resource usage patterns to assist in capacity planning. By understanding peak loads and resource utilization trends, teams can make informed decisions on scaling infrastructure and deploying additional resources as needed.

Graylog

1. Enhanced Log Management for Cloud Applications: Use the Graylog Telegraf plugin to aggregate logs from cloud-deployed applications across multiple servers. By integrating this plugin, teams can centralize logging data, making it easier to troubleshoot issues, monitor application performance, and maintain compliance with logging standards.

2. Real-Time Security Monitoring: Leverage the Graylog plugin to collect and send security-related metrics and logs to a Graylog server for real-time analysis. This allows security teams to quickly identify anomalies, track potential breaches, and respond to incidents promptly by correlating logs from various sources within the infrastructure.

3. Dynamic Alerting and Notification System: Implement the Graylog plugin to enhance alerting mechanisms in your infrastructure. By sending metrics to Graylog, teams can set up dynamic alerts based on log patterns or unexpected behavior, enabling proactive monitoring and rapid incident response strategies.

4. Cross-Platform Log Consolidation: Use the Graylog plugin to facilitate cross-platform log consolidation across diverse environments such as on-premises, hybrid, and cloud. By standardizing logging in the GELF format, organizations can ensure consistent monitoring and troubleshooting practices, regardless of where their services are hosted.
