I recently installed netdata on KVM host using netdata image version 1.33.1… Cannot see any VM guest data in charts. I checked cgroup:plugins and it is enabled… tried to search through community but could not find anything
[plugins]
cgroups = yes
Seems this may be the problem… but not sure how to get the date command of alpine linux.
bash-5.1# ./cgroup-name.sh
./cgroup-name.sh: line 20: /usr/bin/date: No such file or directory
: cgroup-name.sh: FATAL: called without a cgroup name. Nothing to do.
bash-5.1#
Is there a container with Redhat image
Hi there,
Could you share some more info?
- access the netdata conf: <node_ip>:19999/netdata.conf and share the
[plugin:cgroups]config - kernel version
uname -r - Host OS distr/version
- ( it might be useful later) Selinux status on the host:
/etc/selinux/config - Install method (from what I see you are trying to monitor you host with netdata via a docker container). Have you create the container with the exact command in our docs? Install Netdata with Docker | Learn Netdata
Tasos.
Thanks and appreciate you looking into this…

From the host - [root@adckvm644a ~]# uname -r

From the container -
bash-5.1# uname -a

Red Hat Enterprise Linux release 8.2 (Ootpa)
[root@adckvm644a ~]# cat /etc/selinux/config

Install Method – pulled the image from docker hub.
Will check your docs… but i believe the docker hub image has date command missing, which is causing cgroup script to fail.

So you just ran docker run netdata/netdata?
This won’t work as expected . Please remove the container and create it with this Install Netdata with Docker | Learn Netdata command
I did follow the process, but it seems the image is not compatible on redhat… I used the whole command line as mentioned in Netdata docs. just curious if you have a working environment with kvm guests on redhat running with this image.
