Query Editor 8 | 9 | Forked from InfluxDB plugin, this datasource frontend has been implemented. Therefore, you can issue SQL queries in the same manner as in influxDB. 10 | 11 | (Defining with query editor)
12 | ![Query Editor](https://github.com/sraoss/grafana-sqldb-datasource/wiki/images/query-editor.png) 13 | 14 | Each parts (schema, table, column name and data type) refer to information_schema in RDB. 15 | 16 | ### 2. Text Editor Mode (support raw SQL) 17 | 18 | You can switch to raw query mode by clicking icon. 19 | 20 | (Toggling edit mode)
21 | ![Query Editor](https://github.com/sraoss/grafana-sqldb-datasource/wiki/images/rawquery.png) 22 | 23 | Raw queries are generated referring to inputs of query editor. You can modify them (add JOIN another tables, sub queries in WHERE clause, and so on). 24 | 25 | #### Macros 26 | 27 | If you tries to modify a raw query or define it by yourself without choosing parts in query editor, you can use these macros. 28 | 29 | | macro | detail | 30 | |:------|:-------| 31 | | $timeColumn | This is replaced to "TIME" from [TIME : TYPE] in query editor. | 32 | | $dateColumn | This is replaced to "DATE" from [DATE] in query editor (optional). | 33 | | $timeFilter | This is replaced to "$timeColumn < $from AND $timeColumn > $to". | 34 | | $from | This is replaced to "from" word of the time range for panels, and this is casted as "TYPE" from [TIME : TYPE] in query editor. | 35 | | $to | This is replaced to "to" of the time range for panels, and this is casted as "TYPE" from [TIME : TYPE] in query editor.| 36 | | $unixFrom | This is replaced to "from" of the time range for panels, and this is casted as number of unix timestamp. | 37 | | $unixTo | This is replaced to "to" of the time range for panels, and this is casted as number of unix timestamp. | 38 | | $timeFrom | This is replaced to "from" of the time range for panels, and this is casted as timestamp. | 39 | | $timeTo | This is replaced to "to" of the time range for panels, and this is casted as timestamp. | 40 | | $dateFrom | This is replaced to "from" of the time range for panels, and this is casted as date. | 41 | | $dateTo | This is replaced to "to" of the time range for panels, and this is casted as date. | 42 | 43 | ### 3. Templating 44 | 45 | You can create a template variable in Grafana and have that variable filled with values from any SQL Database metric exploration query. Then, You can use this variable in your SQL Database metric queries. 46 | 47 | (Defining a template)
48 | ![Template Editor](https://github.com/sraoss/grafana-sqldb-datasource/wiki/images/template_var.png) 49 | 50 | (Use a template vartiable in query editor)
51 | ![Query Editor](https://github.com/sraoss/grafana-sqldb-datasource/wiki/images/template_tag.png) 52 | 53 | 54 | ### 4. Annotations 55 | 56 | Annotaions is also supported. You can issue SQL queries and add event information above graphes.　 57 | 58 | (Defining an annotation)
59 | ![Annotations Editor](https://github.com/sraoss/grafana-sqldb-datasource/wiki/images/annotation.png) 60 | 61 | (Annotations in a graph)
62 | ![Annotations Graph](https://github.com/sraoss/grafana-sqldb-datasource/wiki/images/annotation_graph.png) 63 | 64 | ### 5. Using timestamp and unixtimestamp as a time-serise column 65 | 66 | You can choose a time-series column from the table definition. 67 | 68 | (Choosing the column for time series)
69 | ![time series](https://github.com/sraoss/grafana-sqldb-datasource/wiki/images/time-series.png) 70 | 71 | #### Data types 72 | 73 | The supported data types for time-series are: 74 | 75 | | category | PostgreSQL | MySQL | ClickHouse | 76 | |:---------|:-----------|:-------|:-----------| 77 | | timestamp type | timestamp without time zone
timestamp with time zone | timestamp
datetime | 78 | | number type
(if you use unixtimesamp as a time-serise column) | bigint
integer (int)
float

double precision
decimal
numeric | bigint

Alias patterns
45 |
    46 |
  • $t = replaced with table name
    • 47 |
  • $table = replaced with table name
    • 48 |
  • $col = replaced with column name
    • 49 |
  • $alias = replaced with an alias (e.g. $country)
    • 50 |
51 |
52 | 53 |
54 |
Stacking
55 |
    56 |
  • When stacking is enabled it important that points align
    • 57 |
  • If there are missing points for one series it can cause gaps or missing bars
    • 58 |
  • Use the group by time option below your queries and specify for example >10s if your metrics are written every 10 seconds
    • 59 |
  • This will insert zeros for series that are missing tables and will make stacking work properly
    • 60 |
61 |
62 | 63 |
64 |
Group by time
65 |
    66 |
  • Group by time is important, otherwise the query could return many thousands of datapoints that will slow down Grafana

  • Leave the group by time field empty for each query and it will be calculated based on time range and pixel width of the graph
    • 68 |
  • The low limit can only be set in the group by time option below your queries
    • 69 |
  • You set a low limit by adding a greater sign before the interval
    • 70 |
  • Example: >60s if you write metrics to RDB every 60 seconds

Alias patterns
45 |
    46 |
  • $t = replaced with table name
    • 47 |
  • $table = replaced with table name
    • 48 |
  • $col = replaced with column name
    • 49 |
  • $alias = replaced with an alias (e.g. $country)
    • 50 |
51 |
52 | 53 |
54 |
Stacking
55 |
    56 |
  • When stacking is enabled it important that points align
    • 57 |
  • If there are missing points for one series it can cause gaps or missing bars
    • 58 |
  • Use the group by time option below your queries and specify for example >10s if your metrics are written every 10 seconds
    • 59 |
  • This will insert zeros for series that are missing tables and will make stacking work properly
    • 60 |
61 |
62 | 63 |
64 |
Group by time
65 |
    66 |
  • Group by time is important, otherwise the query could return many thousands of datapoints that will slow down Grafana
    • 67 |
  • Leave the group by time field empty for each query and it will be calculated based on time range and pixel width of the graph
    • 68 |
  • The low limit can only be set in the group by time option below your queries
    • 69 |
  • You set a low limit by adding a greater sign before the interval
    • 70 |
  • Example: >60s if you write metrics to RDB every 60 seconds
    • 71 |
72 |
Variables
73 |
    74 |
  • $timeColumn > $timeFrom AND $timeColumn < $timeTo
    • 75 |
  • $timeColumn > $unixFrom AND $timeColumn < $unixTo
    • 76 |
  • $dateColumn > $dateFrom AND $dateColumn < $dateTo
    • 77 |
  • $timeFilter - expands to time and date filter.
    • 78 |
  • $filter - expands to Ad-Hoc filters or '1'.
    • 79 | 80 |
