Kibana Input Plugin

The kibana plugin queries the Kibana API to obtain the service status.

• Telegraf minimum version: 1.8
• Kibana minimum tested version: 6.0

Global configuration options

In addition to the plugin-specific configuration settings, plugins support additional global and plugin configuration settings. These settings are used to modify metrics, tags, and field or create aliases and configure ordering, etc. See the CONFIGURATION.md for more details.

Configuration

# Read status information from one or more Kibana servers
[[inputs.kibana]]
  ## Specify a list of one or more Kibana servers
  servers = ["http://localhost:5601"]

  ## Timeout for HTTP requests
  timeout = "5s"

  ## HTTP Basic Auth credentials
  # username = "username"
  # password = "pa$$word"

  ## 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
 
  ## If 'use_system_proxy' is set to true, Telegraf will check env vars such as
  ## HTTP_PROXY, HTTPS_PROXY, and NO_PROXY (or their lowercase counterparts).
  ## If 'use_system_proxy' is set to false (default) and 'http_proxy_url' is
  ## provided, Telegraf will use the specified URL as HTTP proxy.
  # use_system_proxy = false
  # http_proxy_url = "http://localhost:8888"

Metrics

• kibana
  • tags:
    • name (Kibana reported name)
    • source (Kibana server hostname or IP)
    • status (Kibana health: green, yellow, red)
    • version (Kibana version)
  • fields:
    • status_code (integer, green=1 yellow=2 red=3 unknown=0)
    • heap_total_bytes (integer)
    • heap_max_bytes (integer; deprecated in 1.13.3: use heap_total_bytes field)
    • heap_used_bytes (integer)
    • heap_size_limit (integer)
    • uptime_ms (integer)
    • response_time_avg_ms (float)
    • response_time_max_ms (integer)
    • concurrent_connections (integer)
    • requests_per_sec (float)

Example Output

kibana,host=myhost,name=my-kibana,source=localhost:5601,status=green,version=6.5.4 concurrent_connections=8i,heap_max_bytes=447778816i,heap_total_bytes=447778816i,heap_used_bytes=380603352i,requests_per_sec=1,response_time_avg_ms=57.6,response_time_max_ms=220i,status_code=1i,uptime_ms=6717489805i 1534864502000000000

Run example environment

Requires the following tools:

• Docker
• Docker Compose

From the root of this project execute the following script: ./plugins/inputs/kibana/test_environment/run_test_env.sh

This will build the latest Telegraf and then start up Kibana and Elasticsearch, Telegraf will begin monitoring Kibana's status and write its results to the file /tmp/metrics.out in the Telegraf container.

Then you can attach to the telegraf container to inspect the file /tmp/metrics.out to see if the status is being reported.

The Visual Studio Code Remote - Containers extension provides an easy user interface to attach to the running container.
