Lambda 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 data about corresponding request (execution time and etc).

• tags

  tag name	description
  service	always “lambda-<lambda-id>”
  route	concatenation of a request method and a request resource (POST:/main)
  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 “lambda-<lambda-id>”
  route	concatenation of a request method and a request resource (POST:/main)
  status_code	http status code of response
  error_code	luna error code

• fields

  fields	description
  request_id	request id

Database

Monitoring is implemented as data sending to an influx database.
