mvexpand command: Examples
The following are examples for using the SPL2 mvexpand
command.
To learn more about the mvexpand
command, see How the SPL2 mvexpand command works.
1. Expand the values in a specific field
Suppose you have the fields a
, b
, and c
. Each field has the following corresponding values:
a | b | c |
---|---|---|
1 | x | V1, V2, V3 |
2 | y | V4, V5 |
You run the mvexpand
command and specify the c
field.
... | mvexpand c
This example takes each row from the incoming search results and then create a new row with for each value in the c
field.The other fields will have duplicate values, while the c
field will have each value from the multivalue field in a separate row.
a | b | c |
---|---|---|
1 | x | V1 |
1 | x | V2 |
1 | x | V3 |
2 | y | V4 |
2 | y | V5 |
2. Limit the number of values from the multivalue field to expand
Limit the number of values to expand to 10. Any remaining values are dropped.
... | mvexpand limit=10 my_mvfield
3. Pipeline example
Consider the following raw event data:
_raw |
---|
9/13/2024 09:00:00 SERVER myserver |
To separate the IP addresses from the _raw
field, use the mvexpand
command.
$pipeline = from $source | rex field=_raw max_match=0 /(?P<iplist>\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3})/ | mvexpand iplist | into $destination
The results look like this:
_raw | iplist |
---|---|
9/13/2024 09:00:00 SERVER myserver |
192.0.2.1 |
9/13/2024 09:00:00 SERVER myserver |
192.0.2.2 |
9/13/2024 09:00:00 SERVER myserver |
192.0.2.3 |
