+# What's new in Grafana v2.6
|
|
|
+
|
|
|
+## Release highlights
|
|
|
+The release includes a new Table panel, a new InfluxDB query editor, support for Elasticsearch Pipeline Metrics and
|
|
|
+support for multiple Cloudwatch credentials.
|
|
|
+
|
|
|
+### Table Panel
|
|
|
+<img src="/img/v2/table-panel.png">
|
|
|
+
|
|
|
+The new table panel is very flexible, supporting both multiple modes for time series as well as for
|
|
|
+table, annotation and raw JSON data. It also provides date formating and value formating and coloring options.
|
|
|
+
|
|
|
+#### Time series to rows
|
|
|
+
|
|
|
+In the most simple mode you can turn time series to rows. This means you get a `Time`, `Metric` and a `Value` column.
|
|
|
+Where `Metric` is the name of the time series.
|
|
|
+
|

|
|
|
+
|
|
|
+#### Table Transform
|
|
|
+Above you see the options tab for the **Table Panel**. The most important option is the `To Table Transform`.
|
|
|
+This option controls how the result of the metric/data query is turned into a table.
|
|
|
+
|
|
|
+#### Column Styles
|
|
|
+The column styles allow you control how dates and numbers are formatted.
|
|
|
+
|
|
|
+### Time series to columns
|
|
|
+This transform allows you to take multiple time series and group them by time. Which will result in a `Time` column
|
|
|
+and a column for each time series.
|
|
|
+
|
|
|
+<img src="/img/v2.6/table_ts_to_columns.png">
|
|
|
+
|
|
|
+In the screenshot above you can see how the same time series query as in the previous example can be transformed into
|
|
|
+a different table by changing the `To Table Transform` to `Time series to columns`.
|
|
|
+
|
|
|
+### Time series to aggregations
|
|
|
+This transform works very similar to the legend values in the Graph panel. Each series gets its own row. In the Options
|
|
|
+tab you can select which aggregations you want using the plus button the Columns section.
|
|
|
+
|
|
|
+<img src="/img/v2.6/table_ts_to_aggregations.png">
|
|
|
+
|
|
|
+You have to think about how accurate the aggregations will be. It depends on what aggregation is used in the time series query,
|
|
|
+how many data points are fetched, etc. The time series aggregations are calculated by Grafana after aggregation is performed
|
|
|
+by the time series database.
|
|
|
+
|
|
|
+#### Raw logs queries
|
|
|
+
|
|
|
+If you want to show documents from Elasticsearch pick `Raw Document` as the first metric.
|
|
|
+
|
|
|
+<img src="/img/v2.6/elastic_raw_doc.png">
|
|
|
+
|
|
|
+This in combination with the `JSON Data` table transform will allow you to pick which fields in the document
|
|
|
+you want to show in the table.
|
|
|
+
|
|
|
+<img src="/img/v2.6/table_json_data.png">
|
|
|
+
|
|
|
+#### Elasticsearch aggregations
|
|
|
+
|
|
|
+You can also make Elasticsearch aggregation queries without a `Date Histogram`. This allows you to
|
|
|
+use Elasticsearch metric aggregations to get accurate aggregations for the selected time range.
|
|
|
+

|
|
|
+
|
|
|
+#### Annotations
|
|
|
+
|
|
|
+The table can also show any annotations you have enabled in the dashboard.

|
|
+### The New InfluxDB Editor
|
|
|
+The new InfluxDB editor is a lot more flexible and powerful. It supports nested functions, like `derivative`.
|
|
|
+It also uses the same technique as the Graphite query editor in that it presents nested functions as chain of function
|
|
|
+transformations. It tries to simplify and unify the complicated nature of InfluxDB's query language.
|
|
|
+
|
|
|
+<img src="/img/v2.6/influxdb_editor_v3.gif">
|
|
|
+
|
|
|
+In the `SELECT` row you can specify what fields and functions you want to use. If you have a
|
|
|
+group by time you need an aggregation function. Some functions like derivative require an aggregation function.
|
|
|
+
|
|
|
+The editor tries simplify and unify this part of the query. For example:
|
|
|
+
|
|
|
+
|
|
|
+The above will generate the following InfluxDB `SELECT` clause:
|
|
|
+
|
|
|
+```sql
|
|
|
+SELECT derivative(mean("value"), 10s) /10 AS "REQ/s" FROM ....
|
|
|
+```
|
|
|
+
|
|
|
+#### Select multiple fields
|
|
|
+Use the plus button and select Field > field to add another SELECT clause. You can also
|
|
|
+specify a `asterix` to select all fields.
|
|
|
+
|
|
|
+### Group By
|
|
|
+To group by a tag click the plus icon at the end of the GROUP BY row. Pick a tag from the dropdown that appears.
|
|
|
+You can remove the group by by clicking on the `tag` and then click on the x icon.
|
|
|
+
|
|
|
+
|
|
|
+The new editor also allows you to remove group by time and select `raw` table data. Which is very useful
|
|
|
+in combination with the new Table panel to show raw log data stored in InfluxDB.
