Prometheus.yml targets in separate file?

Prometheus server
4

I found another service discovery that looks even better – dns_sd_config. As I understand it will find all node_exporter nodes automatically.

but when I added the three items needed to configure it to my prometheus.yml , I get this error when cycling prometheus:

“Error reloading config” err=“couldn’t load configuration (–config.file=“prometheus.yml”): parsing YAML file prometheus.yml: yaml: line 8: could not find expected ‘:’”

Here’s my prometheus.yml Line 8 is the “names”

global:
  scrape_interval: 10s
  evaluation_interval: 10s

#BEGIN DNS Node Scan
dns_sd_config

 - names: pace.gatech.edu

# The type of DNS query to perform. One of SRV, A, or AAAA.
#[ type: <string> | default = 'SRV' ]

# The port number used if the query type is not SRV.
 - port: 9100

 - refresh_interval: 1800

#END DNS Node Scan


I get the same error if I format names: like so (on two lines)

 - names:
     pace.gatech.edu
