# SSV formatter

The SSV formatter sums all dimensions in [results of database queries](../../queries)
to a single value and returns a list of such values showing how it changes through time.

It supports the following formats:

format|content type|description
:---:|:---:|:-----
`ssv`|text/plain|a space separated list of values
`ssvcomma`|text/plain|a comma separated list of values
`array`|application/json|a JSON array

The CSV formatter respects the following API `&options=`:

option|supported|description
:---:|:---:|:---
`nonzero`|yes|to return only the dimensions that have at least a non-zero value
`flip`|yes|to return the numbers older to newer (the default is newer to older)
`percent`|yes|to replace all values with their percentage over the row total
`abs`|yes|to turn all values positive, before using them
`min2max`|yes|to return the delta from the minimum value to the maximum value (across dimensions)

## Examples

Get the average system CPU utilization of the last hour, in 6 values (one every 10 minutes):
