Hello @kondalarao, use the df command. 

df -h

It will show you all the files and how much space they are taking up. The only way out is deleting the files you do not need.

Check filesystem usage.

df -h

If /var is showing 100% full then check actual usage of /var

du -h -x /var|tail -1   ---> It will show actual usage of  /var

Check for deleted files which are getting accessed. If actual usage of /var is less than showing in “df -h” command then there must be issue with open log files which are deleted but still accessed by Process.

Check for deleted files which are getting accessed.

lsof +L1

lsof | grep "/var" | grep deleted

You will also get process id accessing that files. Just kill or stop these processes. And now check filesystem usage, it should show normal.
