Configure Enterprise Tools cluster

Daria Barysheva
IMPORTANT
Before the subsequent monitoring configuring, make sure that the Enterprise Tools (ET) cluster is installed via ADCM. All the following actions are performed on its base.

Step 1. Add monitoring services to the ET cluster

The steps for adding services to a cluster are listed below:

  1. From the CLUSTERS tab switch to the cluster configuring. To do this, click the row that contains the added cluster or click the icon in the Config column. Both methods open the cluster menu.

    et config cluster
    Switching to cluster configuring

  2. Open the Services tab in the cluster menu and click Add services.

    Switching to services adding

  3. In the opened dialog, select the services that should be added to the cluster, and click Add.

    mon offline services add 02
    Choosing services

    The brief description of available services is listed below.

    Monitoring services that should be added to the Enterprise Tools cluster
    Service Purpose

    Diamond

    A Python service used for collecting system metrics from the hosts that are connected to the monitoring system. The collected metrics are processed by Carbon (the backend services of Graphite)

    Graphite

    Includes several components:

    • Carbon — a set of services that are used to process metrics collected by Diamond.

    • Whisper DB — a temporary file database where collected metrics are stored.

    • Web service — allows to get and visualize metrics from Whisper DB.

    Grafana

    A web service that allows to create convenient sets of graphs, alerts, and other visualization tools for metrics received from Graphite. By default, uses the port 3000

  4. As a result, the added services are displayed at the Services tab.

Step 2. Distribution of monitoring components

The steps of adding components to hosts are listed below:

  1. From the CLUSTERS tab switch to the cluster configuring. To do this, click the row that contains the added cluster or click the icon in the Config column. Both methods open the cluster menu.

    et config cluster
    Switching to cluster configuring

  2. Open the Hosts - Components tab in the cluster menu, add monitoring components to all cluster hosts, and click Save.

Step 3. Configure monitoring services

  1. From the CLUSTERS tab switch to the cluster configuring. To do this, click the row that contains the added cluster or click the icon in the Config column. Both methods open the cluster menu.

    et config cluster
    Switching to cluster configuring

  2. Open the Services tab in the cluster menu, find the row that contains the desired service, and click the gear icon in the Config column.

    Switching to service configuring

  3. In the opened window, fill in the configuration parameters of the selected service. The fields highlighted in orange are mandatory. After completing the service configuring, click Save.

Step 4. Install monitoring services

  1. Run the Install Monitoring action at the CLUSTERS tab.

    mon offline services install 01
    Switching to installing monitoring

  2. In the opened window, click Run.

    mon offline services install 07
    Verifying installing

  3. Wait until the installing process is completed.

    NOTE
    In case of errors, you can find the logs at the JOBS tab.

Step 5. Verify results

Graphite

To check availability of the Graphite web-interface, you can do:

  1. Enter in the browser bar the address of the host where the monitoring cluster is deployed. To specify the port number, use the value of the Web-interface TCP port parameter from the ip_and_ports section defined when configuring the Graphite service during the monitoring cluster installation. The value 80 (used by default) can be omitted.

    IMPORTANT
    In case of offline installation, this address matches the address of the host where the Enterprise Tools cluster is deployed.

  2. Expand a tree at the left side of the opened form. System metrics are displayed there, grouped by hosts. You can select some of these metrics to view their change dynamics in the form of a graph at the right side of the screen.

Grafana

To check availability of the Grafana web-interface, you can do:

  1. Enter in the browser bar the address of the host where the monitoring cluster is deployed. To specify the port number, use the value of the Port parameter from the ip_and_ports section defined when configuring the Grafana service during the monitoring cluster installation (by default 3000).

  2. Select the Home menu item in the opened form.

  3. Open one of available dashboards. For example, Arenadata System metrics.

    mon offline services install 04
    Switching to Arenadata System metrics

  4. View available graphs.
