rrdinfoSYNOPSISrrdtool info filename [--daemon|-d address [--noflush|-F]] DESCRIPTIONThe info function prints the header information from an RRD in a parsing friendly format. Check rrdcreate if you are uncertain about the meaning of the individual keys.
EXAMPLEThis is the output generated by running info on a simple RRD which contains two data sources and one RRA. Note that the number after the last_update keyword is in seconds since 1970. The string NaN stands for *UNKNOWN* data. In the example it means that this RRD has neither minimum nor maximum values defined for either of its data sources. filename = "random.rrd" rrd_version = "0001" step = 300 last_update = 955892996 header_size = 2872 ds[a].type = "GAUGE" ds[a].minimal_heartbeat = 600 ds[a].min = NaN ds[a].max = NaN ds[a].last_ds = "UNKN" ds[a].value = 2.1824421548e+04 ds[a].unknown_sec = 0 ds[b].type = "GAUGE" ds[b].minimal_heartbeat = 600 ds[b].min = NaN ds[b].max = NaN ds[b].last_ds = "UNKN" ds[b].value = 3.9620838224e+03 ds[b].unknown_sec = 0 rra[0].cf = "AVERAGE" rra[0].pdp_per_row = 1 rra[0].cdp_prep[0].value = nan rra[0].cdp_prep[0].unknown_datapoints = 0 rra[0].cdp_prep[1].value = nan rra[0].cdp_prep[1].unknown_datapoints = 0 ENVIRONMENT VARIABLESThe following environment variables may be used to change the behavior of
