Monitoring

Data for monitoring

  Now we monitor two types of events for monitoring: request and error. First type is all requests, second is failed requests only. Every event is a point in the time series. The point is represented as union of the following data:

• series name (now requests and errors)

• start request time

• tags, indexed data in storage, dictionary: keys - string tag names, values - string, integer, float

• fields, non indexed data in storage, dictionary: keys - string tag names, values - string, integer, float

‘Requests’ series. Triggered on every request. Each point contains a data about corresponding request (execution time and etc).

• tags

  tag name	description
  service	always “luna-image-store”
  route	concatenation of a request method and a request resource (POST:/buckets)
  status_code	http status code of response

• fields

  fields	description
  request_id	request id
  execution_time	request execution time

‘Errors’ series. Triggered on failed request. Each point contains error_code of luna error.

• tags

  tag name	description
  service	always “luna-image-store”
  route	concatenation of a request method and a request resource (POST:/buckets)
  status_code	http status code of response
  error_code	luna error code

• fields

  fields	description
  request_id	request id

Every handler can add additional tags or fields.

Database

Monitoring is implemented as data sending to an influx database. You can setup your database credentials in configuration file in section “monitoring”.
