Collect real-time kvm vm performance graphics using collectD and visage

Software features:

The collectD software is used to monitor and collect performance data of KVM virtual machines, including CPU, memory, disk Io, and network traffic.

Use the visage software to plot the collected data.

Installation:

System Environment: ubuntu12.04

CollectD

First, download the collectD package collectd-5.4.0 on the collectD Official Website

Install the collectD dependency package

apt-get install bison flex autoconf pkg-config libtool libgcrypt11-dev librrd-dev

After the installation is complete, go to the collectd-5.4.0 directory to compile the source code and install

./configure --prefix=/ --exec-prefix=/usr  --enable-cpu --enable-network --enable-libvirt --enable-logfile --enable-rrdtool  --enable-rrdcachedmake&&make install

Modify configurations

mkdir /etc/collectmv /etc/collectd.conf /etc/collectvi /etc/collect/collectd.conf

Modify the content in the collectD. conf file

Copy the collectD execution file to the/ECT/init. d/directory under the installation directory and start collectD.

service collectd start

Visage

Install the visage dependency package

apt-get install -y build-essential librrd-ruby ruby ruby-dev rubygems

Install visage Software

apt-get install gemgem install visage-app

Start visage

visage-app start

Access the web interface of visage-app after startup

http://visage-app-server:9292

Answer:

When visage-app is started, the following error occurs:

Compile ollectd to install types. RB is in the/share/collectD/directory by default. copy the RB file to the/usr/share/collectD directory and set collectD. set parameters in the conf configuration file:
Typesdb "/usr/share/collectD/types. DB"
Then start collectD and visage-app

Visage-the app cannot collect data

Why can't I find the server on the visage-app interface? By default, the visage-app starts to collect servers in the/var/lib/collectD/RRD directory, but the collectD compilation and installation data is in the/var/lib/collectD/directory by default. In the collectD. conf configuration file, set the parameter basedir "/var/lib/collectD/RRD"
