Readme for collectd docker container in barometer project
==============================================================================
This text file includes information about environment preparation and
deployment collectd in docker container
Table of content:
1. DESCRIPTION
2. SYSTEM REQUIREMENTS
3. INSTALLATION NOTES
4. ADDITIONAL STEPS
------------------------------------------------------------------------------
1. DESCRIPTION
This Dockerfile provides instruction for building collect in isolated container
------------------------------------------------------------------------------
2. SYSTEM REQUIREMENTS
Docker >= 17.06.0-ce
------------------------------------------------------------------------------
3. INSTALLATION NOTES
To build docker container run
sudo docker build -f ./docker/Dockerfile .
from barometer folder.
To run builded image run
sudo docker images
Get docker image id
sudo docker run -ti --net=host -v `pwd`/../src/collectd_sample_configs:/opt/collectd/etc/collectd.d \
-v /var/run:/var/run -v /tmp:/tmp --privileged <image id> /run_collectd.sh
To make some changes run
sudo docker run -ti --net=host -v `pwd`/../collectd_sample_configs:/opt/collectd/etc/collectd.d \
-v /var/run:/var/run --privileged <image id> /bin/bash
/opt/collectd/sbin/collectd -f
------------------------------------------------------------------------------
4. ADDITIONAL STEPS
To check if container works properly additional packages should be installed
on host system.
MCELOG
To simulate mcelog message use instruction in http://artifacts.opnfv.org/barometer/docs/index.html#mcelog-plugin
git clone https://github.com/andikleen/mce-inject
cd mce-inject/
make
sudo make install
modprobe mce-inject
go to mcelog folder
sudo make test
if runs multiple times mcelog service shoud be restarted(cause mcelog make test exits closes mcelog)
VIRT
http://artifacts.opnfv.org/barometer/docs/index.html#virt-plugin
Check that libvirtd is running on the remote host
systemctl status libvirtd
virsh list
virsh perf instance-00000003
sudo virsh perf instance-00000003 --enable cpu_cycles --live
sudo virsh perf instance-00000003 --enable cmt --live
sudo virsh perf instance-00000003 --enable mbmt --live
sudo virsh perf instance-00000003 --enable mbml --live
sudo virsh perf instance-00000003 --enable instructions --live
sudo virsh perf instance-00000003 --enable cache_references --live
sudo virsh perf instance-00000003 --enable cache_mises --live
sudo virsh perf instance-00000003 --enable cache_misses --live
OVS
To successfuly run ovs plugins in Docker you need an ovs instance to connect to
sudo yum install -y openvswitch-switch
sudo service openvswitch-switch start
sudo ovs-vsctl set-manager ptcp:6640
Alternatively you can build ovs from source
yum -y install make gcc openssl-devel autoconf automake rpm-build \
redhat-rpm-config python-devel openssl-devel kernel-devel \
kernel-debug-devel libtool wget python-six selinux-policy-devel
mkdir -p ~/rpmbuild/SOURCES
cd ~/rpmbuild/SOURCES
wget http://openvswitch.org/releases/openvswitch-2.5.3.tar.gz
tar xfz openvswitch-2.5.3.tar.gz
sed 's/openvswitch-kmod, //g' rhel/openvswitch.spec > rhel/openvswitch_no_kmod.spec
rpmbuild -bb --nocheck rhel/openvswitch_no_kmod.spec
cd ../RPMS/x86_64/
yum install -y openvswitch-2.5.3-1.x86_64.rpm
sudo systemctl start openvswitch.service
sudo ovs-vsctl set-manager ptcp:6640
To check if connection is successfull please check
sudo ovs-vsctl show
319efc53-b321-49a9-b628-e8d70f9bd8a9
Manager "ptcp:6640"
is_connected: true - can be a marker that ovs plugins successfully connected
ovs_version: "2.5.3"
on the host.
