# SSV formatter
The SSV formatter sums all dimensions in [results of database queries](/web/api/queries/README.md)
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 SSV 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):
```bash
# curl -Ss 'https://registry.my-netdata.io/api/v1/data?chart=system.cpu&format=ssv&after=-3600&points=6&group=average'
1.741352 1.6800467 1.769411 1.6761112 1.629862 1.6807968
```
---
Get the total mysql bandwidth (in + out) for the last hour, in 6 values (one every 10 minutes):
Netdata returns bandwidth in `kilobits`.
```bash
# curl -Ss 'https://registry.my-netdata.io/api/v1/data?chart=mysql_local.net&format=ssvcomma&after=-3600&points=6&group=sum&options=abs'
72618.7936215,72618.778889,72618.788084,72618.9195918,72618.7760612,72618.6712421
```
---
Get the web server max connections for the last hour, in 12 values (one every 5 minutes)
in a JSON array:
```bash
# curl -Ss 'https://registry.my-netdata.io/api/v1/data?chart=nginx_local.connections&format=array&after=-3600&points=12&group=max'
[278,258,268,239,259,260,243,266,278,318,264,258]
```
