How to plot a bar chart to plot fields with KB,Bytes,MB and GB values?

Hi ,

I have split the below log into key value paris ParEdenSpace_init=6.5 MB ParEdenSpace_Used=204.6 ParEdenSpace_Commited=1.7 GB and ParEdenSpace_Max=12.8 GB.

I have used below query to plot the data, however, the minParEdenSpaceUsed value is in KB but it is showing high value in the graph attached. How would I normalize the values before I plot the data and how to identify if the value is in bytes, MB or GB and then convert into standard GB or MB.

timechart span=1d min(ParEdenSpace_Used) as minParEdenSpaceUsed ,max(ParEdenSpace_Used) as  maxParEdenSpaceUsed,min(ParEdenSpace_Committed) as  minParEdenSpace_Committed,max(ParEdenSpace_Committed) as  maxParEdenSpace_Committed,,max(ParEdenSpace_Max) as  maxParEdenSpace_Max

sometime the same field value has value in KB,MB and GB .ParEdenSpace_Used can have values like 294.9 KB,2G B ,1.9 MB etc

To make it easy to understand (because you weren't sure if you'd convert to GB or MB above), I'll propose a way to normalize to bytes. This approach will split each relevant field into two pieces - val and multiplier. Based on the value of the field multiplier, a case statement multiplies the val by 1024 (to convert from KB), 1024*1024 (to convert from MB), 1024*1024*1024 (to convert from GB), or by no multiplier (to keep bytes in bytes).

| foreach minParEdenSpaceUsed, maxParEdenSpaceUsed, minParEdenSpace_Committed, maxParEdenSpace_Committed, maxParEdenSpace_Max 
    [ eval <<FIELD>>=split('<<FIELD>>', " ") 
    | eval val=mvindex(<<FIELD>>, 0), multiplier=mvindex(<<FIELD>>, 1) 
    | eval <<FIELD>>=case(multiplier="bytes", val, multiplier="KB", val*1024, multiplier="MB", val*1024*1024, multiplier="GB", val*1024*1024*1024) 
    | fields - val multiplier ]

If you wanted to convert to GB or MB, you'd adjust that math accordingly.

If you do following search, what output (value) you get for various fields? Can you post some sample results from below query?

your base search | head 1 | table ParEdenSpace_Used ParEdenSpace_Used  ParEdenSpace_Committed ParEdenSpace_Committed ParEdenSpace_Max
