How to get the difference of value between two tables?

[aaa2324]

Hi Team,

I need to find difference between two tables and generate an alert when the diffence between Table B and Table A is greater than 3 and publish the diffence in table. Kindly help on this

Table A       Table B   

3234          3240

4234           4236

2345           2348

1345           1349

Hey @aaa2324 ,

Try renaming the columns in the table and remove the spaces in the column name and then you'll be able to calculate the difference easily. Your query should look something like below:

<<your_base_query>>
| rename "Table A" as Table_A "Table B" as Table_B
| eval diff=Table_B-Table_A

And then you can save this search as an alert and have the alert triggered if diff>3.
