Hi,

I have the below type of logs:

log1: Mon Feb 8 02:57:36 EST 2021 41% /logs

log2: Mon Feb 8 02:57:36 EST 2021 73% /opt

log3: Mon Feb 8 02:57:36 EST 2021 69% /var

log4: Mon Feb 8 02:57:36 EST 2021 48% /apps

I want to create a table as below:

File_System           Disk_Usage

\logs                             41

\opt                              73

\var                               69

\apps                           48

Here I want to extract the "Disk_Usage" and "File_System" fields with the respective values. This might be a very silly question but I might be missing out something while creating the rex command. So please help me create the rex command. you kind support will be highly appreciated.

 

Thank you.

hi @Mrig342,

Try this,

| makeresults 
| eval _raw=" _raw
Mon Feb 8 02:57:36 EST 2021 41% /logs
Mon Feb 8 02:57:36 EST 2021 73% /opt
Mon Feb 8 02:57:36 EST 2021 69% /var
Mon Feb 8 02:57:36 EST 2021 48% /apps" 
| multikv forceheader=1 
| rex "\s(?<Disk_Usage>\d+)\%\s\/(?<File_System>\w+)" 
| table File_System, Disk_Usage
