How does the Status History panel work?


On the grafana website there is a status history panel like the below

What does the data need to look like for this to work?

I’ve got a simple sql query that gives me

  • server name
  • timestamp
  • value

or simply put, something like this:

from mytable 
where time between $__timeFrom() AND $__timeTo()

However, everything ends up squashed up

Hi @xbalayer

I believe that the Status history panel expects data as a simple data frame (timestamp, single value). You will note on the example on that each row in the status history is returning a distinct time series, and that series contains only timestamps and single values.

Try splitting your query up into multiple queries, where each returns the values for an invidual system, like this:

Note the dropdown when viewing this in the table panel, which means that there are multiple series to choose from. This is what you want to achieve. This renders like so in the Status History panel:

Thank you, that explains it well.

Unfortunately it won’t work for my specific use-case as I have a dynamic set of series and there is no way to “repeat” queries based on each series.

My workaround was to use a normal table with coloured cells by pivoting the query in SQL:

Hello xbalayer, I’m trying to do something similar with some data I have as well. Is it possible you can share a little more details on how you did this. I have 3 fields similar I’m trying to show in my panel but i have no idea how to configure the table to show it how you have it above. Any assistance would be greatly appreciated.

Hi @terrancej

My data is in SQL Server, so this only really applies if you are using a SQL database. This can also be slightly improved code-wise with SQL Server 2019, but this will work either way.

Since I wanted to make the days dynamic both the columns in @cols and query in @query needed to be dynamic too.


select @cols = STUFF((SELECT distinct ',' + QUOTENAME(CAST(timestamp AS DATE)) 
                    from vcom.dbo.system_daily_pr where timestamp between $__timeFrom() and $__timeTo()
                    order by ',' + QUOTENAME(CAST(timestamp AS DATE))
            FOR XML PATH(''), TYPE
            ).value('.', 'NVARCHAR(MAX)') 

set @query = 'SELECT systemKey,' + @cols + ' 
                select systemKey, timestamp, value
                from vcom.dbo.system_daily_pr

			) x
                for timestamp in (' + @cols + ')
            ) p '


Thanks xbalayer, I really appreciate it. Have a great day.

You can use a transform. The SQL query returns 3 columns: time, metric, value. You need 2 columns: time, [value], where [value] has the contents of value but the column name of metric.

Use regular SQL query with 3 columns, then add transforms:

Grouping to matrix

  • Column: metric
  • Row: time
  • Cell value: value

Organize fields:

  • Rename the time column back to “time”

Convert field type:

  • Field time as Time
