Logs

The agent gathers metrics using the uWSGI stats server, so you should enable it.

You can do so by adding the options --stats 127.0.0.1:1717 --memory-report to your server. Note that without --memory-report, the metric uwsgi_memory_used won’t be available.

By default, the agent assumes that the stats server is enabled on port 1717, if your server uses another port, you can change it in the configuration.

If some auto-detected parameters are wrong, you can manually override them by adding the following to /etc/glouton/conf.d/99-local.conf:

service:
  [...]
  # For a uWSGI running outside a container
  - type: "uwsgi"
    address: "127.0.0.1"
    port: 8080
    stats_port: 1717
    # If your server uses the --stats-http option, you should set the protocol to "http".
    # If the protocol is not set, "tcp" is used by default.
    stats_protocol: "tcp"

  # For an additional uWSGI running outside a container
  - type: "uwsgi"
    instance: "NAME_ASSOCIATED_WITH_YOUR_ADDITIONAL_SERVICE"
    address: "127.0.0.1"
    port: 8080
    stats_port: 1717

  # For a uWSGI running in a Docker container
  - type: "uwsgi"
    instance: "CONTAINER_NAME"
    port: 8080
    stats_port: 1717

The following metrics are gathered:

Metric	Description
service_status	Status of uWSGI
uwsgi_requests	Number of requests per second
uwsgi_transmitted	Amount of data transmitted in bits/s
uwsgi_memory_used	Memory used in bytes
uwsgi_avg_request_time	Average time to process a request in seconds
uwsgi_exceptions	Number of exceptions per second
uwsgi_harakiri_count	Number of worker timeout per second
