Deploying Operational 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¶

1. 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
  

2. Configure the environment

The easiest way to configure our environment will be to create a parameter file, let’s called paramters.yaml with all the paramteres 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
  

3. 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
   

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