Chapter 4. Installing the Performance Monitoring Suite

Locate a bare metal system that meets the following minimum specifications:

Allow the system to access the Operational Tools packages:

Open the firewall on the system to allow connections to Graphite and Grafana:

# firewall-cmd --zone=public --add-port=2003/tcp --permanent
# firewall-cmd --zone=public --add-port=3030/tcp --permanent
# firewall-cmd --reload

Once that is done, install the Graphite and Grafana software by running the following command:

# yum install python-carbon graphite-web grafana httpd

Configure the Grafana web interface to allow access. Edit /etc/httpd/conf.d/graphite-web.conf and modify the Require line as follows:

...
<Directory "/usr/share/graphite/">
    <IfModule mod_authz_core.c>
        # Apache 2.4
        Require all granted
    </IfModule>
...

Synchronize the database behind Graphite web. Run the following command; when prompted if you want to create a super user, choose no:

# sudo -u apache /usr/bin/graphite-manage syncdb --noinput

Start and enable all the Graphite and Grafana services:

# systemctl start httpd
# systemctl enable httpd
# systemctl start carbon-cache
# systemctl enable carbon-cache
# systemctl start grafana-server
# systemctl enable grafana-server

Configure Grafana to talk to your Graphite instance:

Enable the Operational Tools repository:

# subscription-manager repos --enable=rhel-7-server-openstack-8-optools-rpms

Install collectd:

# yum install collectd

Configure collectd to send the data to the performance monitoring aggregator/relay. To do so, create /etc/collectd.d/10-write_graphite.conf with the following contents, where PERFORMANCE_MONITORING_HOST is the host name or IP address of the host that was configured previously to be the performance monitoring aggregator/relay:

<LoadPlugin write_graphite>
  Globals false
</LoadPlugin>

<Plugin write_graphite>
  <Carbon>
    Host "PERFORMANCE_MONITORING_HOST"
    Port "2003"
    Prefix "collectd."
    EscapeCharacter "_"
    StoreRates true
    LogSendErrors true
    Protocol "tcp"
  </Carbon>
</Plugin>

If you are using SELinux, allow collectd to tcp network connect:

# setsebool -P collectd_tcp_network_connect=1

Start and enable collectd:

# systemctl start collectd
# systemctl enable collectd
