Hi ,
I have added urls for blackbox monitoring in prometheus and also added
alert if url is not giving 302 redirect for 5mins. But the output of
blackbox exporter is constantly giving zero value if the urls give 302
value still and constant alerts are coming which are false. Can someone pls
help me with this.It was working fine for past days but today it gives this
weird issue .
prometheus.yml
- job_name: 'blackbox'
metrics_path: /probe
params:
module: [http_3xx] # Look for a HTTP 302 response.
static_configs:
- targets:
- https://..........
relabel_configs:
- source_labels: [__address__]
target_label: __param_target
- source_labels: [__param_target]
target_label: instance
- target_label: __address__
replacement: localhost:9115 # blackbox exporter
Alertmanager.yml configuration :
- receiver: Monitoring
group_wait: 15m
match_re:
severity: url-down
alert.rules.yml :
- alert: URL-Monitoring
expr: (sum(probe_success{job="blackbox"}) by (instance)) == 0
for: 5m
labels:
severity: url-down
annotations:
summary: Health API endpoint down for '{{ $labels.instance }}'
