Hi, It still doesn’t work. When I debug rrdcached, it seems that rrdcached does not receive any packet. Then I try to deploy the rrdcached in another machine, When rrdc_connect within rrdcached plugin is executed, I can monitor the connection is setup. But when rrdc_update is executed, no packet can be found in wireshard.
BTW: Both collectd and rrdcached are running by root user. B.R.

I have gone through the old threads and have tried “chmod 777 /root/tools/rrdcached”. But it doesn’t work. What is the problem? B.R.
