A Data Source (ds) - * can be a traffic counter, a temperature, the number of users logged - * into a system. The rrd database format can handle the input of - * several Data Sources (ds) in a singe database. - * - * dst - Data Source Type (dst). The Data Source Type (dst) defines the rules - * applied to Build Primary Data Points from the input provided by the - * data sources (ds). - * - * pdp - Primary Data Point (pdp). After the database has accepted the - * input from the data sources (ds). It starts building Primary - * Data Points (pdp) from the data. Primary Data Points (pdp) - * are evenly spaced along the time axis (pdp_step). The values - * of the Primary Data Points are calculated from the values of - * the data source (ds) and the exact time these values were - * provided by the data source (ds). - * - * pdp_st - PDP Start (pdp_st). The moments (pdp_st) in time where - * these steps occur are defined by the moments where the - * number of seconds since 1970-jan-1 modulo pdp_step equals - * zero (pdp_st). - * - * cf - Consolidation Function (cf). An arbitrary Consolidation Function (cf) - * (averaging, min, max) is applied to the primary data points (pdp) to - * calculate the consolidated data point. - * - * cdp - Consolidated Data Point (cdp) is the long term storage format for data - * in the rrd database. Consolidated Data Points represent one or - * several primary data points collected along the time axis. The - * Consolidated Data Points (cdp) are stored in Round Robin Archives - * (rra). - * - * rra - Round Robin Archive (rra). This is the place where the - * consolidated data points (cdp) get stored. The data is - * organized in rows (row) and columns (col). The Round Robin - * Archive got its name from the method data is stored in - * there. An RRD database can contain several Round Robin - * Archives. Each Round Robin Archive can have a different row - * spacing along the time axis (pdp_cnt) and a different - * consolidation function (cf) used to build its consolidated - * data points (cdp). - * - * rra_st - RRA Start (rra_st). The moments (rra_st) in time where - * Consolidated Data Points (cdp) are added to an rra are - * defined by the moments where the number of seconds since - * 1970-jan-1 modulo pdp_cnt*pdp_step equals zero (rra_st). - * - * row - Row (row). A row represent all consolidated data points (cdp) - * in a round robin archive who are of the same age. - * - * col - Column (col). A column (col) represent all consolidated - * data points (cdp) in a round robin archive (rra) who - * originated from the same data source (ds). - * - */ - -/**************************************************************************** - * POS 1: stat_head_t static header of the database - ****************************************************************************/ - -typedef struct stat_head_t { - - /* Data Base Identification Section ***/ - char cookie[4]; /* RRD */ - char version[5]; /* version of the format */ - double float_cookie; /* is it the correct double - * representation ? */ - - /* Data Base Structure Definition *****/ - unsigned long ds_cnt; /* how many different ds provide - * input to the rrd */ - unsigned long rra_cnt; /* how many rras will be maintained - * in the rrd */ - unsigned long pdp_step; /* pdp interval in seconds */ - - unival par[10]; /* global parameters ... unused - at the moment */ -} stat_head_t; - - -/**************************************************************************** - * POS 2: ds_def_t (* ds_cnt) Data Source definitions - ****************************************************************************/ - -enum dst_en { DST_COUNTER=0, /* data source types available */ - DST_ABSOLUTE, - DST_GAUGE, - DST_DERIVE}; - -enum ds_param_en { DS_mrhb_cnt=0, /* minimum required heartbeat.
