Zenoss, Not able to understand use of data values

Question

I am working on a project in which we are monitoring data of some virtual devices which is running on zenoss server , I get the actual data by calling several api's lets suppose calling on some url which ends with /getRRDInfoTabDevice gives value of data store and data point, then i again make call using this values and i get data in xml which is as follows

<row><t>2147483700</t><v0>1.8917126005e-305</v0></row>

where t is data for time, and v0 is actual data, so my question is what is the use of this value v0, as one can see its in e-305 which is almost near to zero ?

Answer 1

This value is in octet /second , this value is used to monitor cpu utilization , network utilization etc. It basically depends on what you are monitoring through your rrdtool.
