I am using API to get objects/rrdexport. I am getting the output as below. This is not clear to me as what this data really mean, specially "rta,rtmax,rtmin & pl and how to interpret its associated values"
{
"meta": {
"start": "1552395900",
"step": "300",
"end": "1552395900",
"rows": "289",
"columns": "4",
"legend": {
"entry": [
"rta",
"pl",
"rtmax",
"rtmin"
]
}
},
"data": {
"row": [
{
"t": "1552395900",
"v": [
"6.7376000000e-02",
"0.0000000000e+00",
"1.7447000000e-01",
"3.8218000000e-02"
]
},
