Generate measurement logs with timestamps #552
Description
Currently Gatekeeper generates measurement logs without a timestamp. For example:
GATEKEEPER GK: The GK block basic measurements at lcore = 10: [tot_pkts_num = 446848, tot_pkts_size = 238366782, pkts_num_granted = 440041, pkts_size_granted = 234185440, pkts_num_request = 4579, pkts_size_request = 623809, pkts_num_declined = 2228, pkts_size_declined = 1942893, tot_pkts_num_dropped = 2228, tot_pkts_size_dropped = 1942893, tot_pkts_num_distributed = 0, tot_pkts_size_distributed = 0]
We are working on storing Gatekeeper measurements in InfluxDB, and having date and time information in the log message would make the job easier. The format of the timestamp is not that important as long as it can be parsed with some ease by some strptime-like function. My suggestion is YYYY-MM-DD HH:MM:SS.
