+/*! Configuration for osmo_time_cc.
+ * Report the cumulative counter of time for which a flag is true as rate counter.
+ * For example, for each second that the flag is true, increment a rate counter.
+ *
+ * The flag to be monitored is reported by osmo_time_cc_set_flag().
+ *
+ * The granularity defines how much time one rate counter increment represents:
+ * the default configuration is gran_usec = 1000000, i.e. one rate counter increment represents one second.
+ *
+ * Reporting as rate counter is configurable by round_threshold_usec and forget_sum_usec, examples:
+ *
+ * round_threshold_usec:
+ * - To get "ceil()" behavior, set round_threshold_usec = 1. This increments the rate counter for each gran_usec period
+ * where the flag was seen true, even if it was true for only a very short fraction of a gran_usec period.
+ * - To get "round()" behavior, set round_threshold_usec = half of gran_usec. The rate counter increments when the flag
+ * has been true for 0.5 of a gran_usec (and then again at 1.5 * gran_usec) of 'true' flag. round_threshold_usec = 0
+ * is a special value that means to use half of gran_usec.
+ * - To get "floor()" behavior, set round_threshold_usec >= gran_usec. The rate counter increments when reaching full
+ * gran_usec periods of the flag being true.
+ *
+ * forget_sum_usec:
+ * This is a tradeoff between the accuracy of the reported rate counter and making sure that the events reported are not
+ * irrelevantly long ago.
+ * - To keep sub-granularity-period surplus time forever, set forget_sum_usec = 0.
+ * - To keep surplus time for up to a minute, set forget_sum_usec = 60000000 (60 seconds).
+ * - To get rid of "leftover" time (almost) immediately after the flag goes false, set forget_sum_usec = 1.
+ * - If gran_usec is set to one second and forget_sum_usec is set to one minute, the reported rate counter has a
+ * possible inaccuracy of 1/60th, but makes sure that no timings older than a minute affect the current reports.
+ *
+ * Reporting modes in detail:
+ *
+ * The rate_ctr increments when the cumulative counter passes round_threshold_usec (default: half of gran_usec).
