New returns a new Logger object with cloud logging client initialized if running on GCE.

NewCloudproberLog is a convenient wrapper around New that sets context to context.Background and attaches cloudprober prefix to log names.

MaxLogEntrySize Max size of each log entry (100 KB) This limit helps avoid creating very large log lines in case someone accidentally creates a large EventMetric, which in turn is possible due to unbounded nature of "map" metric where keys are created on demand.

EnvVars defines environment variables that can be used to modify the logging behavior.

LogPrefixEnvVar environment variable is used to determine the stackdriver log name prefix.

Logger implements a logger that logs messages to Google Cloud Logging.
