Data Normalisation. You have not collected enough data yet. You are submitting your data with 'N' for 'Now' as the time point; however, RRDTool stores in regular Interval steps. Assuming your interval is 5min, then you need to cover the whole 5min before the cdp (consolidated data point) in the RRA can be written, which means that you will usually need to least 2 updates before it starts to write. After that, you should get one data point every update.
If your DS type is not Gauge, then you definitely need 2 data points in order to work out the slope. If you have an Interval of X seconds and a heartbeat of H, and your smallest RRA has a Consolidation step size of S, then continue to submit data points at approximately X seconds intervals but not more than H seconds for at least X(S+1) seconds, and you should see data points start to appear in the RRA.

I have database with 9 DS: DS:Cluj-Napoca:GAUGE:360:0:1000 \ DS:Timisoara:GAUGE:360:0:1000 \ DS:Iasi:GAUGE:360:0:1000 \ DS:Constanta:GAUGE:360:0:1000 \ DS:Craiova:GAUGE:360:0:1000 \ DS:Brasov:GAUGE:360:0:1000 \ DS:Galati:GAUGE:360:0:1000 \ DS:Ploiesti:GAUGE:360:0:1000 \ DS:Oradea:GAUGE:360:0:1000 \ And the update command is: rrdtool update wazers_ro.rrd N:${USERS[1]}:${USERS[2]}:${USERS[3]}:${USERS[4]}:${USERS[5]}:${USERS[6]}:${USERS[7]}:${USERS[8]}:${USERS[9]} However only the first value gets update. If I do a dump on the file this is what I get: <row><v> 2.1000000000e+01 </v><v> NaN </v><v> NaN </v><v> NaN </v><v> NaN </v><v> NaN </v><v> NaN </v><v> NaN </v><v> NaN </v></row> So, why aren't the other values going into the database? Thanks. -- View this message in context: http://rrd-mailinglists.937164.n2.nabble.com/Issue-only-the-first-value-gets-into-the-database-tp7582340.html Sent from the RRDtool Users Mailinglist mailing list archive at Nabble.com. _______________________________________________ rrd-users mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users _______________________________________________ rrd-users mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users
