Check log file or check db file
- to check a log file for excessive activity
Run: sudo tail -f <file>
for example:
sudo tail -f /var/log/synocal.log
- to check a db file
Don’t use tail -f for a db file. Instead open the application and check the logging to this specific application.
for example for DNS:
/var/packages/DNSServer/target/named/var/log/SYNODNSLOGDB
Open DNS server and check the logging. If DNS server is responsible for the excessive writes change the log settings in this application.
