Systems, methods and computer program products are provided. An indication that a log of data entries has reached a size limit for the log is received. The data entries are continually stored in the log over time, and each entry comprises an associated log level. A threshold log level for data entries in the log is determined. At least one new data entry for the log is received. An existing data entry having a log level less than or equal to the threshold log level is overwritten by the new data entry, so that the size limit is not exceeded.
