resource.metrics.monitoring

This repository contains the source code necessary to build Ubuntu Hyper-V hard-drives containing the Chronograf and Kapacitor applications.

Image

The image is created by using the Linux base image and amending it using a Chef cookbook which installs chronograf and kapacitor.

Contents

In addition to the default applications installed in the template image the following items are also installed and configured:

Configuration

The configuration for the Chronograf and Kapacitor instances comes from a Consul-Template template file which replaces some of the template parameters with values from the Consul Key-Value store.

Chronograf

The Chronograf configuration only requires the address for the Influx service.

Kapacitor

The Kapacitor configuration requires

  • The address of the Influx service
  • Information about the email domain in order to send emails

Provisioning

No additional configuration is applied other than the default one for the base image.

Logs

No additional configuration is applied other than the default one for the base image.

Metrics

Metrics are collected by Telegraf.

Build, test and release

The build process follows the standard procedure for building Calvinverse images.

Deploy

  • Download the new image to one of the Hyper-V hosts.
  • Create a new directory in one of the designated workspace hard-disks (workspace 1 - 6) for the image under the suitable environment folder (e.g. test-01 when adding the image to the test environment) and copy the image VHDX file there
  • Create a VM that points to the image VHDX file with the following settings
    • Name: <Environment>_<ResourceName>-<Number>
    • Generation: 2
    • RAM: 1024 Mb. Do not use dynamic memory
    • Network: VM
    • Hard disk: Use existing. Copy the path to the VHDX file
  • Update the VM settings:
    • Enable secure boot. Use the Microsoft UEFI Certificate Authority
    • Attach a DVD image that points to an ISO file containing the settings for the environment. These are normally found in the output of the Calvinverse.Infrastructure repository. Pick the correct ISO for the task, in this case the Linux Consul Client image
  • Start the VM, it should automatically connect to the correct environment once it has provisioned
  • Remove the old VM
    • SSH into the host
    • Issue the consul leave command
    • Shut the machine down with the sudo shutdown now command
    • Once the machine has stopped, delete it

Usage

The Chronograf webpage will be made available from the proxy at the /dashboards/monitoring sub-address.
