How to add sub totals to a table

[vshakur]

Suppose I have the following table:

comonent | count |

--------------|---------|
a1 | 3 |
a2 | 5 |
a3 | 6 |
b1 | 2 |

b2 | 5 |

I would like to add two rows to the table that would represent the sum of all the a's and the b's. In other words, I'd like to create new components called a-total and b-total that would contain the sum of all the a components and the b components respectfully, and then add those components to the component field.

If you need to sort as well (giving all a's and corresponding a-total, then all b's and corresponding b-total), try like this

your current search giving fields component and count
| eval keep=0
| appendpipe [| where match(component,"^a") | addcoltotals labelfield=component label="a-total" 
 eval keep=1]
| appendpipe [| where match(component,"^b") | addcoltotals labelfield=component label="b-total" 
 eval keep=1]
| where keep=1

Here's one way to do it:

your base search 
| appendpipe 
  [ | where match(component, "^a") 
    | stats sum(count) AS count 
    | eval component="a-total" ] 
| appendpipe 
  [ |where match(component, "^b") 
    | stats sum(count) AS count 
    | eval component="b-total" ]

The appendpipe command allows you to add some more calculations while preserving the original query results.
