I think you are asking for an availability report for all nodes over past week. If so, create a custom table and enter 'node' type and 'node name'->'contains'->'sol'
And click 'add to layout'
Click 'edit table' then click the plus symbol to add a column. Select:
- Average Availability
If you have a custom field you want to group by (node function, site location etc) add this too then also select it on the 'group results by' at the bottom.
Expand 'average availability'
Select 'custom format' for the display setting and enter '0.00 %' in the empty field.
Select 'Average' for data aggregation (this is important).
Expand the timestamp column and tick 'hide from view' then under the 'date/time column in this table is' select 'timestamp' and sample interval 'week'.
You will see next to the datasource drop down you now have a 'from' from down. Select 'last 7 days'.
You will now see something like mine below (I grouped by a custom field which specifies the device funtion and also added a response time column):
