Techniques perform log management. Such techniques involve obtaining a count value of a counter associated with a log entry in the log, the count value of the counter incrementing at a predetermined frequency. Such techniques further involve determining a rough time instant when the log entry is created based on the count value, a reference count value of the counter associated with the log entry, a reference time corresponding to the reference count value and the frequency. Such techniques further involve correcting the rough time instant based at least in part on the frequency and a set of count values of the counter corresponding to a set of time instants, to determine a corrected time when the log entry is created. Accordingly, the log backed up to the external storage device has accurate time information.

Techniques for issuing a data storage management request may include: receiving, from a client at a data storage system, a set of one or more messages; performing natural language processing on the set of one or more messages to extract first information used in forming the data storage management request; executing the data storage management request in accordance with the first information extracted; and responsive to executing the request, sending a response to the client indicating a result of executing the data storage management request. State information may be retained in connection with a first conversation to obtain information for a first request or command. If the first conversation is interrupted to commence a second conversation for a second request, the state information may be stored for the duration of the second conversation and then restored to resume the first conversation from the point of interruption.
