v1.0.0

1.0.0 (December 7, 2020)

UPGRADE NOTES:

• The terraform modules source path in your stack configuration requires to be updated to use to new module path in /modules root directory to meet terraform registry requirements.
  Please follow this doc to update any existing configuration.
• You can use, if you prefer, the terraform registry from now as source instead of the git or github source types.

BREAKING CHANGES:

• All existing stack configuration using path from the old tree structure will fail for every modules using v1+ tag with the error "no module found"
  The tag v0.4.1 contains exactly same features than v1.0.0 on the detectors scope and it will be the last one supporting tree structure.

NOTES:

• It has the same functional scope than https://github.com/claranet/terraform-signalfx-detectors/releases/tag/v0.4.1 and if resource is preserved in the state file after upgrade you should not see any diff. Its changes mainly focus move from tree to flat structure, enrich documentation, improve CI and provide tooling to help developer to contribute
• It is the first version compatible with the terraform registry using a flat structure. All modules are now available here as a flat directories list.

NEW FEATURES:

• provide full modules list and one stack example in terraform registry which become the documentation start point to use a module.
• rework and refactor scripts splitting them into 2 directories module to work on modules changes as dev or stack to generate terraform source to use by end user.
• modules readmes are all generated from a template with a jinja based generator
• detector generator: add support for extrapolation, vm filters, heartbeat subject
• convert most of the detectors from system-common module into yaml configuration as example of using yaml config files and the generator to create new detectors
• add a new makefile which help to setup the tooling environment and perform automation tasks like generate detectors from config files, auto update readme, bootstrap a new module or a new stack..

DOCUMENTATION:

Documentation exist in 2 locations: inside this repository and inside its wiki. Each one has a different purpose.

• In the repo and especially docs root directory, the documentation provides an operational quick start. The users can learn how to deploy detectors easily to test before to go deeper.
  The developers will find tasks to do for every common types of changes known like creating a new detector or a new module.

• Wiki has been improved to provides a conceptual understanding with everything useful to go further in the usage or the development of this project. Users will find advanced usages tricks or tips and more detailed procedures. Developers could learn how it works under the hood to propose global enhancements which could impact all modules.

v0.3.0

ENHANCEMENTS:

v0.2.0

0.2.0 (October 13, 2020)

UPGRADE NOTES:

• notifications global variable assignation should be updated using object and defining every severities. This is a requirement to avoid undesired or missing binding caused by old behavior. Please check this change to see an example of upgrade.

BREAKING CHANGES:

• notifications global variable is now an object where attributes represents every SignalFx severities (Critical, Major, Minor, Warning, Info) for safer assignation
• [my_detector]_notifications is now a map(string) to ease overriding

v0.1.0

0.1.0 (September 11, 2020)

First release 🎉 which integrates the entire perimeter from https://github.com/claranet/terraform-datadog-monitors and more!

• all modules from original repos has been reworked (not simply translated)
• fixes multiple bugs from original repo (i.e. elasticsearch latencies, azure metrics changes ..)
• lot of improvements taking advantages of our experience but also the richness of signalflow (i.e. lasting function)
• add new modules like http, ntp, haproxy, rabbitmq and more
• terraform code updated to take advantage of HCL 2 features
• more variables and more overriding capabilities to increase the level of customization
• modules compatible with terraform >= 0.12.26 (including 0.13)

Next release will come soon focusing on homogenization, documentation and organization:

• reorganize the repo as flat modules list
• modules doc auto generated
• CI improvements
• a main README to explain the purpose of this repo and provide tips and guidance about modules usage
