Description
You can apply this operation either as a Filter or Create columnfield operation:
Filter | Filters those events where a value is less than either another field of the same data type or a specified value. |
---|---|
Create columnfield | Creates a Boolean column that shows true when a value is less than either another field of the same data type or a specified value. |
How does it work in the search window?
Select Filter / Create column field in the search window toolbar, then select the Less than operation. You need to specify two arguments:
Argument | Data type |
---|---|
Value mandatory | Any |
is less than mandatory | The same as the Value data type |
If you use the Create columnfield operation, the data type of the values in the new column field is boolean (true or false).

Working with strings Be aware that in case you use strings, the values will be compared according to the ASCII code, in which each character has an associated value. If you want to know more about the ASCII code, click the following link. |
Example
In the demosiem.logtrust.ecommerceweb.dataactivity
table, we want to get only the events where the number of bytes sent responseTime is less than 800than 500. To do it, we will apply a Filter using the Less than operation.
The arguments needed for the filter are:
Value - bytesTransferred columnresponseTime field
is less than - Click the pencil icon and enter 800500
...
Click Filter data and you will see the following result:
...
Click Create columnfield and follow the same steps to add a new Boolean column that shows true when the values in the bytesTransferred column the responseTime field are less than or equal to 800500.
How does it work in LINQ?
Use the operator where
... to apply the Filter operation and select
... as
... to apply the Create column operation. These are the valid formats of the Less than operation:
value1 < value2
lt(value1, value2)
Examples
You can copy the following LINQ scripts and try the above example on the demo.ecommerce.data
table:
Code Block |
---|
from demo.ecommerce.data where bytesTransferred < 800 |
...
Code Block |
---|
from demo.ecommerce.data where lt(bytesTransferred, 800) |
And this is the same example using the Create column operation:
Code Block |
---|
from demo.ecommerce.data select bytesTransferred < 800 as bytes_lt_800 |
...
