How to create a scatter chart over an undetermined number of events?

Hello,

I am very new to splunk and would greatly appreciate any advice.

I have a collection of reports that each contain the following fields:

BM3_SGA_TGT_SIZE BM2_SGA_TGT_SIZE BM1_SGA_TGT_SIZE B_SGA_TGT_SIZE BP1_SGA_TGT_SIZE BP2_SGA_TGT_SIZE BP3_SGA_TGT_SIZE

BM3_EST_PHYREAD BM2_EST_PHYREAD BM1_EST_PHYREAD B_EST_PHYREAD BP1_EST_PHYREAD BP2_EST_PHYREAD BP3_EST_PHYREAD

BM3_EST_DBTIME BM2_EST_DBTIME BM1_EST_DBTIME B_EST_DBTIME BP1_EST_DBTIME BP2_EST_DBTIME BP3_EST_DBTIME

Each report has been added to splunk as an event.

I would like to create a single scatter that aggregates the data across all the events and plots according to the following:

(1st Y-Axis) BM3_EST_PHYREAD and (2nd Y-Axis)BM3_EST_DBTIME over (X-axis) BM3_SGA_TGT_SIZE

(1st Y-Axis) BM2_EST_PHYREAD and (2nd Y-Axis)BM2_EST_DBTIME over (X-axis) BM2_SGA_TGT_SIZE

(1st Y-Axis) BM1_EST_PHYREAD and (2nd Y-Axis)BM1_EST_DBTIME over (X-axis) BM1_SGA_TGT_SIZE

(1st Y-Axis) B_EST_PHYREAD and (2nd Y-Axis)B_EST_DBTIME over (X-axis) B_SGA_TGT_SIZE

(1st Y-Axis) BP1_EST_PHYREAD and (2nd Y-Axis)BP1_EST_DBTIME over (X-axis) BP1_SGA_TGT_SIZE

(1st Y-Axis) BP2_EST_PHYREAD and (2nd Y-Axis)BP2_EST_DBTIME over (X-axis) BP2_SGA_TGT_SIZE

(1st Y-Axis) BP3_EST_PHYREAD and (2nd Y-Axis)BP3_EST_DBTIME over (X-axis) BP3_SGA_TGT_SIZE

The values and order of TGT_SIZE will be consistent across all events.

The values of PYHREAD and DBTIME will vary across events.

Thus far I have created the following search query:

 

 

 

index=oraawr sourcetype="awr_general_stats" CUSTOMER_NAME="U*" DB_NAME="SA*" INSTANCE_NAME="sa*1" SNAP_ID=*
| eval TGT_SIZE=mvappend(BM3_SGA_TGT_SIZE,BM2_SGA_TGT_SIZE,BM1_SGA_TGT_SIZE,B_SGA_TGT_SIZE,BP1_SGA_TGT_SIZE,BP2_SGA_TGT_SIZE,BP3_SGA_TGT_SIZE)
| eval EST_PHYREAD=mvappend(BM3_EST_PHYREAD,BM2_EST_PHYREAD,BM1_EST_PHYREAD,B_EST_PHYREAD,BP1_EST_PHYREAD,BP2_EST_PHYREAD,BP3_EST_PHYREAD)
| eval EST_DBTIME=mvappend(BM3_EST_DBTIME,BM2_EST_DBTIME,BM1_EST_DBTIME,B_EST_DBTIME,BP1_EST_DBTIME,BP2_EST_DBTIME,BP3_EST_DBTIME)
| table TGT_SIZE EST_PHYREAD EST_DBTIME

 

 

 

 

It returns the following table:

Each row corresponds to a single event.  In this particular case there are 93 events, so there are 93 rows.  

My initial thought was to consolidate  the rows.  So instead of 93x 7 values of TGT_SIZE I would have 691 rows, keeping the order.  Do the same for EST_PHYREAD and EST_DBTIME.

But I can't seem to figure out the correct commands to use.

I guidance would be greatly appreciated.

Thanks,

If you want to expand those rows, you first make a composite field of the 3 values. expand them and split the values out again. like this. I'm guessing the second column in your example was EST_DBTIME, not EST_PHYREAD

... your search ...
| eval data=mvzip(mvzip(TGT_SIZE,EST_PHYREAD,","),EST_DBTIME, ",")
| fields data
| mvexpand data
| rex field=data "(?<TGT_SIZE>[^,]*),(?<EST_PHYREAD>[^,]*),(?<EST_DBTIME>.*)"
| fields TGT_SIZE EST_PHYREAD EST_DBTIME

Thank you very much.  That was very helpful.  Now I just have to find a good scatter visualization.  Do you have any suggestions?

Thanks!

I've used the 3D Scatterplot viz from Splunkbase

https://splunkbase.splunk.com/app/3138

as well as the default one, but the default is a bit clunky.

Other than that, I've not used any other
