Few important tips to take note of

Here we can see about Field Extraction and table formatting

| fields – to make searches more efficient, main part of search

  • -fieldname fieldname2 is different for – fieldname fieldname2

it makes search more efficient if the fields are included or excluded.

| table – like fields- but changes data to tabulated format (transforming command)

fields to be used before using the table command

| dedup – to remove duplicate values form the values displayed in the events/rows

  1. count ex:
  2. top, limit: top vendor limit=5
  3. rare
  4. showperc=true/false
  5. otheruser=true

  5. min
  6. max
  7. list
  8. values
