Deploying Operational Tools¶
TripleO comes with an optional suite of tools designed to help operators maintain an OpenStack environment. The tools perform the following functions:
This document will go through the presentation and installation of these tools.
Operational Tool Server:
Monitoring Relay/proxy (RabbitMQ)
Monitoring Controller/Server (Sensu)
Data Store (Redis)
API/Presentation Layer (Uchiwa)
Log relay/transformer (Fluentd)
Data store (Elastic)
API/Presentation Layer (Kibana)
Performance receptor (Collectd)
An API/Presentation Layer (Grafana)
There is no operational tools installed by default on the undercloud
Deploying the Operational Tool Server¶
There is an ansible project called opstools-ansible (OpsTools) on github that helps to install the Operator Server, further documentation of the operational tool server installation can be founded at (OpsToolsDoc).
Deploying the Undercloud¶
As there is nothing to install on the undercloud nothing needs to be done.
Before deploying the Overcloud¶
The Deploying with Heat Templates document has a more detailed explanation of the following steps.
Install client packages on overcloud-full image:
Mount the image and create a chroot:
temp_dir=$(mktemp -d) sudo tripleo-mount-image -a /path/to/overcloud-full.qcow2 -m $temp_dir sudo mount -o bind /dev $temp_dir/dev/ sudo cp /etc/resolv.conf $temp_dir/etc/resolv.conf sudo chroot $temp_dir /bin/bash
Install the packages inside the chroot:
dnf install -y centos-release-opstools dnf install -y sensu fluentd collectd exit
Unmount the image:
sudo rm $temp_dir/etc/resolv.conf sudo umount $temp_dir/dev sudo tripleo-unmount-image -m $temp_dir
Upload new image to undercloud image registry:
openstack overcloud image upload --update-existing
Operational tools configuration files:
The files have some documentation about the parameters that need to be configured
Configure the environment
The easiest way to configure our environment will be to create a parameter file, let’s called parameters.yaml with all the parameters defined.
MonitoringRabbitHost: server_ip # Server were the rabbitmq was installed MonitoringRabbitPort: 5672 # Rabbitmq port MonitoringRabbitUserName: sensu_user # the rabbitmq user to be used by sensu MonitoringRabbitPassword: sensu_password # The password of the sensu user MonitoringRabbitUseSSL: false # Set to false MonitoringRabbitVhost: "/sensu_vhost" # The virtual host of the rabbitmq
LoggingServers: # The servers - host: server_ip # The ip of the server port: 24224 # Port to send the logs [ 24224 plain & 24284 SSL ] LoggingUsesSSL: false # Plain or SSL connections # If LoggingUsesSSL is set to false the following lines can # be deleted LoggingSharedKey: secret # The key LoggingSSLCertificate: | # The content of the SSL Certificate -----BEGIN CERTIFICATE----- ...contents of server.pem here... -----END CERTIFICATE-----
CollectdServer: collectd0.example.com # Collectd server, where the data is going to be sent CollectdServerPort: 25826 # Collectd port # CollectdSecurityLevel: None # Security by default None the other values are # Encrypt & Sign, but the two following parameters # need to be set too # CollectdUsername: user # User to connect to the server # CollectdPassword: password # Password to connect to the server # Collectd, by default, comes with several plugins # extra plugins can added on this parameter CollectdExtraPlugins: - disk # disk plugin - df # df plugin ExtraConfig: # If the plugins need to be set, this is the location collectd::plugin::disk::disks: - "/^[vhs]d[a-f][0-9]?$/" collectd::plugin::df::mountpoints: - "/" collectd::plugin::df::ignoreselected: false
Continue following the TripleO instructions for deploying an overcloud:
openstack overcloud deploy --templates \ [-e /usr/share/openstack-tripleo-heat-templates/environments/monitoring-environment.yaml] \ [-e /usr/share/openstack-tripleo-heat-templates/environments/logging-environment.yaml] \ [-e /usr/share/openstack-tripleo-heat-templates/environments/collectd-environment.yaml] \ -e parameters.yaml
Wait for the completion of the overcloud deployment process.
