How to use the value of a column as a trigger an alert

[trunghung]

I currently have a table with 3 columns that was created from a few column append search queries.
count count count
Error | day1 | day2 | day3 | % betwen 1 & 2 | % between 1 & 3
Err A | 2 | 4 | 2 | 100% | 0%
Err B | 4 | 5 | 6 | 25% | 50%
Err C |blank | 5 | 6 | infinite % | infinite%

I would like to have an alert that that it would alert me if the increase between days is over 50% on any of the row. Is it possible to do something like that? thank you very much.

Assuming your field names are exactly as they appear in your question above, try this search as the alert search and set "number of events greater than 0" as alert condition

your current search giving above output with fields Error, day1, day2, day3, "% betwen 1 & 2", "% between 1 & 3" 
| where '% between 1 & 3'>50 OR '% between 1 & 2' >50

If you only have fields Error, day1, day2, day3, they try something like this

your current search giving above output with fields Error, day1, day2, day3 | where (day1/day2)>0.5 OR (day1/day3)>0.5
