RRDINFO(1) rrdtool RRDINFO(1) NNAAMMEE rrdtool info - extract header information from an rrd SSYYNNOOPPSSIISS rrrrddttooooll iinnffoo _f_i_l_e_n_a_m_e_._r_r_d DDEESSCCRRIIPPTTIIOONN The iinnffoo 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. EEXXAAMMPPLLEE This is the output generated by running iinnffoo on a simple rrd which contains two datasources and one rra. Note that the number after the _l_a_s_t___u_p_d_a_t_e keyword is in seconds since 1970. The string NNaaNN stands for _*_U_N_K_N_O_W_N_* data. In the example it means that this rrd has neither minimum not maximum values defined for either of its datasources. filename = "randome.rrd" rrd_version = "0001" step = 300 last_update = 955892996 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 _f_i_l_e_n_a_m_e_._r_r_d The name of the RRRRDD you want to dump.
