device polled by sub-poller can not draw as no xx.rrd file
as pic below,how to solve this issue
device first belong to group 0,later changed to sub-poller group
setup rrdcached on one server and configure it on all servers
It should run on one server and be configured on both servers to point to the one server
type
lnms config:get rrdcached
on both nodes … the results should be the same - you can not have multiple rrdcached servers
same with redis
yes,both are the same.
both show unix:/var/run/rrdcached.sock
in sub poller can not find the connection to main rrdcached’s.network itself is ok
what’s the matter?
the remote poller should be set to use the network to connect to rrdcached, not to use a unix socket (which is only local to the host)
ie rrdcached should be ‘somehost.whatever.com:42217’

official docs should be more clear.
I follow that state “you should copy config.php from main to all slave.”
but “But in the end, it was the lack of understanding of the deployment principles that led to the issue.”
