Hello every i change the relabel
y try this
- job_name: '208.67.222.220-opendns' ##REBUILD new blackbox_expoerter
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
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
- job_name: '198.55.49.149-canada' ##REBUILD new blackbox_expoerter
scrape_interval: 5s
metrics_path: /probe
params:
module: [dns_probe]
static_configs:
- 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
with this i can used in target any domain to resolve with labels dns
in the log in blackbox i have this
looking good no?
