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 "google/cloud/logging"

logging = Google::Cloud::Logging.new
entries = logging.entries order: "timestamp desc"

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

Using the enumerator by not passing a block:

require "google/cloud/logging"

logging = Google::Cloud::Logging.new
entries = logging.entries order: "timestamp desc"

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

Limit the number of API calls made:

require "google/cloud/logging"

logging = Google::Cloud::Logging.new
entries = logging.entries order: "timestamp desc"

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

Parameters:

  • request_limit (Integer) —

    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)

#next ⇒ Sink::List

Retrieve the next page of entries.

Examples:

require "google/cloud/logging"

logging = Google::Cloud::Logging.new

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