Hi All,
I am finding this issue of rrd xport not returning rows whereas the
rrd fetch is returning rows with the same parameters.
Would be great if any of you could help me or have faced this issue.I am using
rrdtool version 1.3.6.
Below is the snapshot of the commands executed and their result .
RRDTOOL FETCH: returns one row as shown below
[r...@dev006 ~]# /usr/local/third-party/rrd/bin/rrdtool fetch
/var/stats/rrd_data/service_class_data/service_class_TESTSC04.rrd AVERAGE -r 3
-s 1262886000 -e 1262886180
AccelTrafficBytesIn PThruTrafficBytesIn GoodPutBytesOut
GoodPutBytesIn WanPThruBytesIn BytesOut
1262886600: 4.3554497354e+02 0.0000000000e+00 1.6151587302e+02 5.8164285714e+02
0.0000000000e+00 5.6100264550e+03
RRDTOOL XPORT : things to observe
1) in the result , step is 600 eventhough step is set to 3 in the command
2) start and end time in the result are not the same as in the command
3) no rows are returned.
[r...@dev006 ~]# /usr/local/third-party/rrd/bin/rrdtool xport --step 3 -s
1262886000 -e 1262886180
