Yes.
You didn't show your alerting rules. Are they using "probe_success" by any
chance? There are other metrics you can use. Just type "probe_" into the
Prometheus web UI and look for the auto-completions.
Here is an example. blackbox.yml:
modules:
certificate:
prober: tcp
timeout: 5s
tcp:
tls: true
tls_config: {}
curl 'localhost:9115/probe?module=certificate&target=www.google.com:443'
# HELP probe_dns_lookup_time_seconds Returns the time taken for probe dns
lookup in seconds
# TYPE probe_dns_lookup_time_seconds gauge
probe_dns_lookup_time_seconds 0.001341219
*# HELP probe_duration_seconds Returns how long the probe took to complete
in seconds*
*# TYPE probe_duration_seconds gauge*
*probe_duration_seconds 0.375832381*
# HELP probe_failed_due_to_regex Indicates if probe failed due to regex
# TYPE probe_failed_due_to_regex gauge
probe_failed_due_to_regex 0
# HELP probe_ip_addr_hash Specifies the hash of IP address. It's useful to
detect if the IP address changes.
# TYPE probe_ip_addr_hash gauge
probe_ip_addr_hash 1.255276657e+09
# HELP probe_ip_protocol Specifies whether probe ip protocol is IP4 or IP6
# TYPE probe_ip_protocol gauge
probe_ip_protocol 6
# HELP probe_ssl_earliest_cert_expiry Returns earliest SSL cert expiry date
# TYPE probe_ssl_earliest_cert_expiry gauge
probe_ssl_earliest_cert_expiry 1.599661882e+09
# HELP probe_ssl_last_chain_expiry_timestamp_seconds Returns last SSL chain
expiry in unixtime
# TYPE probe_ssl_last_chain_expiry_timestamp_seconds gauge
probe_ssl_last_chain_expiry_timestamp_seconds 1.599661882e+09
# HELP probe_success Displays whether or not the probe was a success
# TYPE probe_success gauge
probe_success 1
# HELP probe_tls_version_info Returns the TLS version used, or NaN when
unknown
# TYPE probe_tls_version_info gauge
probe_tls_version_info{version="TLS 1.3"} 1
