You don't need a separate job for each DNS server. You can have a single
job with multiple target blocks.
- job_name: 'dns'
scrape_interval: 5s
metrics_path: /probe
params:
module: [dns_probe]
static_configs:
- targets:
- www.google.com
- www.mindfree.cl
labels:
dns: 208.67.220.220 #australia cloudflare
- targets:
- www.google.com
- www.microsoft.com
labels:
dns: 198.55.49.149 #canada
relabel_configs:
- source_labels: [__address__]
#target_label: __param_target
target_label: __param_hostname
# Populate target URL parameter with dns server IP
- source_labels: [__param_hostname]
target_label: instance
#QUERY
- source_labels: [dns]
#target_label: __param_hostname
target_label: __param_target
# Populate __address__ with the address of the blackbox exporter to hit
- target_label: __address__
replacement: localhost:9115
(Although personally, I would use file_sd_configs for this, so I can edit
the targets without having to re-read the prometheus config file).
