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:

• Availability Monitoring

• Centralized Logging

• Performance Monitoring

This document will go through the presentation and installation of these tools.

Architecture

1. 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)

   • Aggregator/Relay (Graphite)

   • An API/Presentation Layer (Grafana)

2. Undercloud:

   • There is no operational tools installed by default on the undercloud

3. Overcloud:

   • Monitoring Agent (Sensu)

   • Log Collection Agent (Fluentd)

   • Performance Collector Agent (Collectd)

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 instalation 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

Note

The Deploying with Heat Templates document has a more detailed explanation of the following steps.

1. 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
     

2. Operational tools configuration files:

   The files have some documentation about the parameters that need to be configured

   • Availability Monitoring:

     /usr/share/openstack-tripleo-heat-templates/environments/monitoring-environment.yaml
     

   • Centralized Logging:

     /usr/share/openstack-tripleo-heat-templates/environments/logging-environment.yaml
     

   • Performance Monitoring:

     /usr/share/openstack-tripleo-heat-templates/environments/collectd-environment.yaml
     

3. 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.

   • Availability Monitoring:

     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
     

   • Centralized Logging:

     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-----
       ...contens of server.pem here...
       -----END CERTIFICATE-----
     

   • Performance Monitoring:

     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
     

4. 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
   

5. Wait for the completion of the overcloud deployment process.
