Trino Grafana Data Source Plugin

The Trino datasource allows to query and visualize Trino data from within Grafana.

Getting started

Drop this into Grafana's plugins directory. To run it locally without installing Grafana, run it in a Docker container using:

docker run -d -p 3000:3000 \
  -v "$(pwd):/var/lib/grafana/plugins/trino" \
  -e "GF_PLUGINS_ALLOW_LOADING_UNSIGNED_PLUGINS=trino-datasource" \
  --name=grafana \
  grafana/grafana-oss

Features

  • HTTP Basic
  • TLS client authentication
• Raw SQL editor only, no query builder yet
• Macros

Macros support

Plugin supports the following marcos:

• $timeFrom($column) - replaced with the lower boundary of the currently selected "Time Range" as a timestamp.
• $timeTo($column) - replaced with the upper boundary of the currently selected "Time Range" as a timestamp.
• $timeGroup($column, $interval) - replaced with an expression that rounds values of a column to the selected "Group by a time interval" value.
• $dateFilter($column) - replaced with a range condition for the currently selected "Time Range" as dates, on a column passed as the $column argument. Use it in queries or query variables as ...WHERE $dateFilter($column)... or ...WHERE $dateFilter(created_at).....
• $timeFilter($column) - replaced with a range condition for the currently selected "Time Range" as timestamps, on a column passed as the $column argument.
• $unixEpochFilter($column) - replaced with a range condition for the currently selected "Time Range", on a column passed as the $column argument.
• $parseTime - parse a timestamp string using the default or specified format.

A description of macros is available by typing their names in Raw Editor

Templating

Using Variables in Queries

Template variable values are only quoted when the template variable is a multi-value.

If the variable is a multi-value variable then use the IN comparison operator rather than = to match against multiple values.

Example with a template variable named hostname:

SELECT
  atimestamp as time,
  aint as value
FROM table
WHERE $__timeFilter(atimestamp) and hostname in($hostname)
ORDER BY atimestamp ASC

Disabling quoting for multi-value variables

Grafana automatically creates a quoted, comma-separated string for multi-value variables. For example: if server01 and server02 are selected then it will be formatted as: 'server01', 'server02'. To disable quoting, use the csv formatting option for variables:

${servers:csv}

Read more about variable formatting options in the Variables documentation.
