Instance Method Details

#all(request_limit: nil) {|entry| ... } ⇒ Enumerator

Retrieves all log entries by repeatedly loading #next until #next? returns false. Calls the given block once for each log entry, which is passed as the parameter.

An Enumerator is returned if no block is given.

This method may make several API calls until all log entries are retrieved. Be sure to use as narrow a search criteria as possible. Please use with caution.

Examples:

Iterating each log entry by passing a block:

require "gcloud"

gcloud = Gcloud.new
logging = gcloud.logging
entries = logging.entries order: "timestamp desc"

entries.all do |entry|
  puts "[#{e.timestamp}] #{e.log_name} #{e.payload.inspect}"
end

Using the enumerator by not passing a block:

require "gcloud"

gcloud = Gcloud.new
logging = gcloud.logging
entries = logging.entries order: "timestamp desc"

all_payloads = entries.all.map do |entry|
  entry.payload
end

Limit the number of API calls made:

require "gcloud"

gcloud = Gcloud.new
logging = gcloud.logging
entries = logging.entries order: "timestamp desc"

entries.all(request_limit: 10) do |entry|
  puts "[#{e.timestamp}] #{e.log_name} #{e.payload.inspect}"
end

Parameters:

  • request_limit (Integer) (defaults to: nil) —

    The upper limit of API requests to make to load all log entries. Default is no limit.

Yields:

  • (entry) —

    The block for accessing each log entry.

Yield Parameters:

  • entry (Entry) —

    The log entry object.

Returns:

  • (Enumerator)

      break if request_limit < 0
    end
    break unless results.next?
    results = results.next
  end
end

#next ⇒ Sink::List

Retrieve the next page of entries.

Examples:

require "gcloud"

gcloud = Gcloud.new
logging = gcloud.logging

entries = dataset.entries
if entries.next?
  next_entries = entries.next
end

#next? ⇒ Boolean

Whether there is a next page of entries.

Examples:

require "gcloud"

gcloud = Gcloud.new
logging = gcloud.logging

entries = logging.entries
if entries.next?
  next_entries = entries.next
end

Returns:

  • (Boolean)
