Troubleshooting Guide

Change log level

Send SIGUSR1 signal to dragonfly process to change log level

kill -s SIGUSR1 <pid of dfdaemon, scheduler, cdn, or manager>

stdout:

change log level to debug
change log level to fatal
change log level to panic
change log level to dpanic
change log level to error
change log level to warn
change log level to info

The change log level event will print in stdout and core.log file, but if the level is greater than info, stdout only.

Download slowly than without Dragonfly

1. Confirm limit rate in dfget.yaml

   download:
     # total download limit per second
     totalRateLimit: 200Mi
     # per peer task download limit per second
     # default is 20Mi, this default is in consideration of extreme environments
     perPeerRateLimit: 100Mi
   upload:
     # upload limit per second
     rateLimit: 100Mi
   

2. Confirm source connection speed in CDN and dfdaemon

500 Internal Server Error

1. Check error logs in /var/log/dragonfly/daemon/core.log
2. Check source connectivity(dns error or certificate error)

Example:

curl https://example.harbor.local/

When curl says error, please check the details in output.
