For example, I would like to get only ERROR, HINT, and STATEMENT from below strings
postgresERROR
postgresHINT
postgresSTATEMENT
If use "%{WORD:log_type}", then I get full string as below, but I am interested in only uppercase word. Please suggest if there are any other ways.
{
"log_type": [
"postgresERROR"
]
}
Thanks!
