v0.7.0 - Improved demo report creation and added select_value option

I was struggling, if I make this a minor or major update. In the end, it doesn't matter: it should be now much more easy, to use the ruby-grafana-reporter!

• breaking changes
• new features
  • added option select_value for grafana_panel_query_value and grafana_sql_value to specify the desired return value. It supports min, max, avg, sum, first, last
• improvements
  • added an animated gif to the readme, which hopefully helps new users to understand on how to use the ruby-grafana-reporter
  • demo report now is now creating with more content, also for very light dashboards, to support better understanding for new users
• bugfixes
  • fix regexp to escape '+' symbol in positive delta times such as e.g. now/h+8h, which lead to an infinite loop (#47)
  • grafana_sql_table and grafana_panel_query_table were not creating any demo entries... this is not fixed
  • fixed build pipeline

Enjoy!

v0.6.6 - Support influx in newer grafana versions and added 'render-scale'

This release contains some improvements and bugfixes, mostly mentioned by you. Thanks for staying with me!
Don't worry about the missing releases - I mistakenly created intermediate releases, which should not have been done.

• breaking changes
• new features
  • now supports option render-scale (#44)
  • supports InfluxDB now for Grafana versions >= 8 (#42)
• improvements
  • explanations in documentation are overworked
  • error messages clarified
  • moved from ocra to ocran to support newer ruby versions
• bugfixes
  • timeout handed over for image renderings are now also forwarded to the webrequest (#45)
  • fixed build pipeline

Looking forward to your feedback!

v0.6.3 - Avoid errors with nil datasources and improved error messages

This release contains a bugfix and further improved debugging capabilities.

• improvements
  • shows whole stacktrace on internal errors
• bugfixes
  • removes nil datasources from grafana datasource array to avoid exceptions including a proper warning message (#35)

If you see FATAL errors when using the reporter, you should definitely move to this version.

Happy to hear your feedback!

v0.6.2 - Support new datasource API for SQL databases

This release adds support to the new datasource API for SQL databases.

• bugfixes
  • SQL queries now support new API endpoint, when using Grafana >= 8.x (#31)
• nerd stuff
  • setup a complete automated build pipeline to reduce efforts for testing in multiple environments and releasing properly

Awaiting your feedback!

v0.6.1 - Bugfix and improved debugging capabilities

This release is mainly intended to debug specific bugs and therefore provides extended debugging capabilities and minor bugfixes.

• improvements
  • adds option verbose_log="true" as option for queries, which prints additional information about query results to the log
  • added grafana_value_as_variable as well as include_headline to the functional documentation
• bugfixes
  • some queries could not be executed, because of wrong evaluation of headlines (#31)

Hopefully this supports debugging us in debugging the issues :-)

v0.6.0 - adjust version dependencies and add support for new prometheus queries

This release updates all dependencies to current docker asciidoctor release, which means Ruby >=2.7 at least.
The main reason for this release anyway was to add support for newer prometheus queries since grafana 7.5.x and to hunt down current bugs reported.

• improvements
  • adjust dependencies to match current docker asciidoctor release
  • add support for prometheus queries for grafana >= 7.5.x
  • datasources now receive information about the used grafana version, so that different handling is possible for different grafana versions
• bugfixes
  • handle properly, if an unsupported variable is used on a dashboard - anyway queries which rely on this, won't run properly, but other queries can be used without any issues
  • handle issue if datasources are nil - which should never happen, but did in bug #29. A message is added to the logs giving more details for a future final fix

Enjoy!

v0.5.4 - Critical bugfix release

This release fixes a critical bug introduced with v0.5.3.

• bugfixes
  • panels using the default datasource could no longer be rendered

v0.5.3 - Support dataframe reponses and variable datasources

This is a quick release, fixing some issues, which are related to new grafana versions and support advanced debugging.

• new features
  • handle panels properly, where the datasource is configured by a variable (#23)
  • support dataframe responses for all internal datasources (#22)
• improvements
  • issues during handling datasource responses will now throw proper error messages, including the query response as raw text for debugging purposes (added to support debugging of #24)

Enjoy!

v0.5.2 - Support newer Grafana versions datasource storage and dataframes for Prometheus

This release contains only bugfixes to enable compatibility with newer Grafana versions.

• new features
  • support dataframes response format for Prometheus queries
• improvements
  • show proper error message if a Datasource cannot handle the query response of Grafana, which might happen more often in future
• bugfixes
  • support new way of storing Grafana datasources in JSON (Hash instead of Strings)

Let me know, if further bugs exist.

v0.5.1 - Improved prometheus support and some other minor improvements

This release mainly improves prometheus support.

• improvements
  • add support for calling prometheus instant queries from sql inline and sql table queries with the parameter instant=true
  • add support for interval option in sql inline or table queries, which will replace $__interval variable in influx queries or will be forwarded to prometheus as step variable
  • add support for inline prometheus queries, including test case, please note: due to a bug ] in an inline prometheus query has to be escaped by \] (added note to help documentation)
  • add full support for vector, scalar and string instant query results of prometheus queries
  • properly handly prometheus query errors
  • improve checks of configuration files before starting up, e.g. checks for http:// or https:// at the beginning of host configurations
• bugfixes
  • use panel configured step configuration in prometheus panels as default for interval option
  • added ERB support note in gem description
  • added missing blanks in log messages

Enjoy!
