[rrd-users] Problems with rrd update on RRD database

[Brian Ipsen]

Hi

 

 I'm having a very strange issue with a RRD database.

 

The database is created using:

 

            rrdtool create file.rrd -b `date +%s` -s 300 \

            DS:BackupDisk:GAUGE:600:0:10 \

            DS:NoBackupDisk:GAUGE:600:0:10 \

            DS:BackupVTape:GAUGE:600:0:10 \

            DS:NoBackupVTape:GAUGE:600:0:10 \

            DS:BackupTape:GAUGE:600:0:10 \

            DS:NoBackupTape:GAUGE:600:0:10 \

            DS:ReclaimVTape:GAUGE:600:0:10 \

            DS:NoReclaimVTape:GAUGE:600:0:10 \

            DS:ReclaimTape:GAUGE:600:0:10 \

            DS:NoReclaimTape:GAUGE:600:0:10 \

            DS:ReclaimCopy:GAUGE:600:0:10 \

            DS:NoReclaimCopy:GAUGE:600:0:10 \

            DS:Migration:GAUGE:600:0:10 \

            DS:NoMigration:GAUGE:600:0:10 \

            DS:Expiration:GAUGE:600:0:10 \

            DS:NoExpiration:GAUGE:600:0:10 \

            DS:FullDbBackup:GAUGE:600:0:10 \

            DS:NoFullDbBackup:GAUGE:600:0:10 \

            DS:IncrDbBackup:GAUGE:600:0:10 \

            DS:NoIncrDbBackup:GAUGE:600:0:10 \

            DS:Export:GAUGE:600:0:10 \

            DS:NoExport:GAUGE:600:0:10 \

            DS:Import:GAUGE:600:0:10 \

            DS:NoImport:GAUGE:600:0:10 \

            RRA:AVERAGE:0.5:1:600 \

            RRA:AVERAGE:0.5:6:700 \

            RRA:AVERAGE:0.5:24:775 \

            RRA:AVERAGE:0.5:288:800 \

            RRA:MAX:0.5:1:600 \

            RRA:MAX:0.5:6:700 \

            RRA:MAX:0.5:24:775 \

            RRA:MAX:0.5:288:800

 

This seem to be OK.. When  I update the RRD, I use:

 

rrdtool update /var/www/html/tsm/rrd/$1-processes.rrd -t
BackupDisk:NoBackupDisk:BackupVTape:NoBackupVTape:BackupDisk:NoBackupDisk:Re
claimVTape:NoReclaimVTape:ReclaimTape:NoReclaimTape:ReclaimCopy:NoReclaimCop
y:Migration:NoMigration:Expiration:NoExpiration:FullDbBackup:NoFullDbBackup:
IncrDbBackup:NoIncrDbBackup:Export:NoExport:Import:NoImport
N:0:1:0:1:1:0:0:1:0:1:0:1:0:1:0:1:0:1:0:1:0:1:0:1

 

But when doing a rrdtool dump of the RRD file, I search for the data I
insert - and now it looks like:

 

                        <!-- 2010-06-24 17:20:00 CEST / 1277392800 -->
<row><v> 1.0000000000e+00 </v><v> 0.0000000000e+00 </v><v> 0.0000000000e+00
</v><v> 1.0000000000e+00 </v><v> NaN </v><v> NaN </v><v> 0.0000000000e+00
</v><v> 1.0000000000e+00 </v><v> 0.0000000000e+00 </v><v> 1.0000000000e+00
</v><v> 0.0000000000e+00 </v><v> 1.0000000000e+00 </v><v> 0.0000000000e+00
</v><v> 1.0000000000e+00 </v><v> 0.0000000000e+00 </v><v> 1.0000000000e+00
</v><v> 0.0000000000e+00 </v><v> 1.0000000000e+00 </v><v> 0.0000000000e+00
</v><v> 1.0000000000e+00 </v><v> 0.0000000000e+00 </v><v> 1.0000000000e+00
</v><v> 0.0000000000e+00 </v><v> 1.0000000000e+00 </v></row>

 

So - for some weird reason the value for BackupDisk is set to 1 in the RRD
file - even though I specified the order and the value - so that it actually
should be 0 . and vice-versa for the value NoBackupDisk

 

What am I doing wrong ? Or is this a bug ??

 

Regards

Brian
