Hello there,
I am trying to use rrd_update_r() to update a rrdb through a c++ program.
So I am generating the argc/argv on the fly to pass into the function.
The originating string is the following:
time_t tm = time(NULL);
stringstream ss;
ss << tm;
string updstr = string("update sensors.rrd \
--template CO2unf:CO2fil:O2pp:O2pct:O2temp:O2pres ")\
+ ss.str() + string(":1015:1000:123:20.63:38.48:987");
I get this error from rrd_get_error():
sensors.rrd: expected timestamp not found in data source from update
Is timestamp not accepted in seconds from EPOCH?
Thank you in advance for your help!
