It can also extract numerical reports. If no _X_P_O_R_T statements are found, there will be no output. --ss|----ssttaarrtt _s_e_c_o_n_d_s (default end-1day) The time when the exported range should begin. Time in seconds since epoch (1970-01-01) is required. Negative numbers are relative to the current time. By default one day worth of data will be printed. See also AT-STYLE TIME SPECIFICATION section in the _r_r_d_f_e_t_c_h documentation for a detailed explanation on how to specify time. --ee|----eenndd _s_e_c_o_n_d_s (default now) The time when the exported range should end. Time in seconds since epoch. See also AT-STYLE TIME SPECIFICATION section in the _r_r_d_f_e_t_c_h documentation for a detailed explanation of ways to specify time. --mm|----mmaaxxrroowwss _r_o_w_s (default 400 rows) This works like the --ww|----wwiiddtthh parameter of _r_r_d_g_r_a_p_h. In fact it is exactly the same, but the parameter was renamed to describe its purpose in this module. See _r_r_d_g_r_a_p_h documentation for details. ----sstteepp _v_a_l_u_e (default automatic) See rrdgraph documentation. ----eennuummddss The generated xml should contain the data values in enumerated tags. <v0>val</v0><v1>val</v1> DDEEFF::_v_n_a_m_e==_r_r_d::_d_s_-_n_a_m_e::_C_F See _r_r_d_g_r_a_p_h documentation.

The first block is enclosed by a mmeettaa element and contains some meta data. The second block is enclosed by a ddaattaa element and contains the data rows. Let's assume that the _x_p_o_r_t command looks like this: rrdtool xport \ --start now-1h --end now \ DEF:xx=host-inout.lo.rrd:output:AVERAGE \ DEF:yy=host-inout.lo.rrd:input:AVERAGE \ CDEF:aa=xx,yy,+,8,* \ XPORT:xx:"out bytes" \ XPORT:aa:"in and out bits" The resulting meta data section is (the values will depend on the RRD characteristics): <meta> <start>1020611700</start> <step>300</step> <end>1020615600</end> <rows>14</rows> <columns>2</columns> <legend> <entry>out bytes</entry> <entry>in and out bits</entry> </legend> </meta> The resulting data section is: <data> <row><t>1020611700</t><v>3.4000000000e+00</v><v>5.4400000000e+01</v></row> <row><t>1020612000</t><v>3.4000000000e+00</v><v>5.4400000000e+01</v></row> <row><t>1020612300</t><v>3.4000000000e+00</v><v>5.4400000000e+01</v></row> <row><t>1020612600</t><v>3.4113333333e+00</v><v>5.4581333333e+01</v></row> <row><t>1020612900</t><v>3.4000000000e+00</v><v>5.4400000000e+01</v></row> <row><t>1020613200</t><v>3.4000000000e+00</v><v>5.4400000000e+01</v></row> <row><t>1020613500</t><v>3.4000000000e+00</v><v>5.4400000000e+01</v></row> <row><t>1020613800</t><v>3.4000000000e+00</v><v>5.4400000000e+01</v></row> <row><t>1020614100</t><v>3.4000000000e+00</v><v>5.4400000000e+01</v></row> <row><t>1020614400</t><v>3.4000000000e+00</v><v>5.4400000000e+01</v></row> <row><t>1020614700</t><v>3.7333333333e+00</v><v>5.9733333333e+01</v></row> <row><t>1020615000</t><v>3.4000000000e+00</v><v>5.4400000000e+01</v></row> <row><t>1020615300</t><v>3.4000000000e+00</v><v>5.4400000000e+01</v></row> <row><t>1020615600</t><v>NaN</v><v>NaN</v></row> </data> EEXXAAMMPPLLEE 11 rrdtool xport \ DEF:out=if1-inouts.rrd:outoctets:AVERAGE \ XPORT:out:"out bytes" EEXXAAMMPPLLEE 22 rrdtool xport \ DEF:out1=if1-inouts.rrd:outoctets:AVERAGE \ DEF:out2=if2-inouts.rrd:outoctets:AVERAGE \ CDEF:sum=out1,out2,+ \ XPORT:out1:"if1 out bytes" \ XPORT:out2:"if2 out bytes" \ XPORT:sum:"output sum" AAUUTTHHOORR Tobias Oetiker <tobi@oetiker.ch> 1.3.8 2008-03-15 RRDXPORT(1)
