Overview
The Agent’s KyotoTycoon check tracks get, set, and delete operations, and lets you monitor replication lag.
Minimum Agent version: 6.0.0
Setup
Installation
The KyotoTycoon check is included in the Datadog Agent package, so you don’t need to install anything else on your KyotoTycoon servers.
Configuration
Edit the kyototycoon.d/conf.yaml file, in the conf.d/ folder at the root of your Agent’s configuration directory. See the sample kyototycoon.d/conf.yaml for all available configuration options:
init_config:
instances:
## @param report_url - string - required
## The report URL should be a URL to the Kyoto Tycoon "report" RPC endpoint.
#
- report_url: http://localhost:1978/rpc/report
Restart the Agent.
Log collection
Collecting logs is disabled by default in the Datadog Agent, enable it in your datadog.yaml file:
Add this configuration block to your kyototycoon.d/conf.yaml file to start collecting Kyoto Tycoon logs:
logs:
- type: file
path: /var/data/ktserver.log
source: kyototycoon
Change the path parameter value based on your environment. See the sample kyototycoon.d/conf.yaml for all available configuration options.
Restart the Agent.
Validation
Run the Agent’s status subcommand and look for kyototycoon under the Checks section.
