CSV formatter

The CSV formatter presents results of database queries in the following formats:

format	content type	description
`csv`	text/plain	a text table, comma separated, with a header line (dimension names) and `\r\n` at the end of the lines
`csvjsonarray`	application/json	a JSON array, with each row as another array (the first row has the dimension names)
`tsv`	text/plain	like `csv` but TAB is used instead of comma to separate values (MS Excel flavor)
`html`	text/html	an html table
`markdown`	text/plain	markdown table

In all formats the date and time is the first column.

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 rows older to newer (the default is newer to older)
`seconds`	yes	to return the date and time in unix timestamp
`ms`	yes	to return the date and time in unit timestamp as milliseconds
`percent`	yes	to replace all values with their percentage over the row total
`abs`	yes	to turn all values positive
`null2zero`	yes	to replace gaps with zeros (the default prints the string `null`

Examples

Get the system total bandwidth for all physical network interfaces, over the last hour, in 6 rows (one for every 10 minutes), in csv format:

Netdata always returns bandwidth in kilobits.

# curl -Ss 'https://registry.my-netdata.io/api/v1/data?chart=system.net&format=csv&after=-3600&group=sum&points=6&options=abs'

Get the max RAM used by the SQL server and any cron jobs, over the last hour, in 2 rows (one for every 30 minutes), in tsv format, and format the date and time as unix timestamp:

Netdata always returns memory in MB.

# curl -Ss 'https://registry.my-netdata.io/api/v1/data?chart=apps.mem&format=tsv&after=-3600&group=max&points=2&options=nonzero,seconds&dimensions=sql,cron'

1540596600  61.95703    0.25

Get an HTML table of the last 4 values (4 seconds) of system CPU utilization:

Netdata always returns CPU utilization as %.

# curl -Ss 'https://registry.my-netdata.io/api/v1/data?chart=system.cpu&format=html&after=-4&options=nonzero'
<html>
