Memory sub-system event log management

A method, comprising:

• receiving data indicative of occurrence of a plurality of events;
• determining respective event log types for the received plurality of events;
• associating respective identifiers including a corresponding counter for each of the determined event log types;
• determining a best bit to event ratio to identify a bit-size of the corresponding counter to be used for each of the determined event log types based at least upon a number of times that the corresponding determined event log types occurred in previous operations;
• changing a size of the respective identifier including the bit-size of the corresponding counter based at least upon the corresponding determined best bit to event ratio;
• updating corresponding counter values to count a number of occurrence of associated event log type;
• and
• storing the updated counter values and corresponding associated event log data including the respective identifiers and the determined event log types to a memory device;
• and
• wherein the size of each of the identifiers is based on a parameter and the parameter is:
• a quantity of the plurality of events;
• or
• a size of a memory space for storing each of the identifiers and associated counters.

A system, comprising:

• a memory device;
• and
• a processing device coupled to the memory device and configured to perform operations comprising:
• receiving data indicative of a plurality of events;
• determining respective event log types of the received plurality of events;
• associating a respective identifier including a corresponding counter for each of event log types;
• determining a best bit to event ratio to identify a size of the corresponding counter to be used for each of the event log types, wherein the best bit to event ratio is based at least upon a number of times that the corresponding event log types occurred in previous operations;
• changing a size of the respective identifier including the size of the corresponding counter based at least upon the corresponding determined best bit to event ratio;
• updating corresponding counter values to count a number of occurrence of associated event log type;
• detecting an occurrence of a triggering event that includes a power down of the system;
• in response to the detected occurrence of the triggering event, storing the updated counter values and corresponding associated event log data including the respective identifiers and the determined event log types to the memory device;
• and
• generating histogram data comprising occurrences of each of the plurality of events and the event log types;
• and
• wherein the size of each of the identifier is based on a parameter and the parameter is:
• a quantity of the plurality of events;
• or
• a size of a memory space for storing each of the identifiers and associated counters.
