Regex help for RouteOnContent processor

avatar
Master Collaborator

Hello Experts,

 

I am looking for a regex to configure in "RouteOnContent" processor of Nifi so that based on specific string in flow file content I can route FF.

 

FF content :

● rclone.service - Rclone(file transfer tool) Remote Service
   Loaded: loaded (/etc/systemd/system/rclone.service; enabled; vendor preset: enabled)
   Active: active (running) since Thu 2022-02-03 09:46:01 UTC; 6h ago
 Main PID: 23647 (rclone)
    Tasks: 13
   Memory: 61.3M
      CPU: 5.143s
   CGroup: /system.slice/rclone.service
           └─23647 /usr/bin/rclone rcd --rc-no-auth --rc-job-expire-duration=60m --cache-tmp-upload-path=/tmp/rclone/upload

 

I want to search for the string "Active: active (running)" in flow file content, if present route to different path.

 

I tried few regex but did not work as expected.

 

Any suggestion would be much appreciated.

 

Thanks

Mahendra

Those parentheses on your search would be considered special characters ina. regular expression unless escaped.

I can get this to work using this:

 

Active: active \(running\)

What @DigitalPlumber said.

Also make sure that Match Requirement is set to "content must contain match", otherwise it won't work.
