Use different receiver for each list in the blackbox file.

[juan chaves]

Hello people.

this is my blackbox configuration it has two files (lists of sites). below my configuration of alerts using slack.

my question is, how can i use different receiver for each list in the blackbox. ex: sites01.yml use slack

sites02.yml use email.

####config blackbox  

- job_name: 'blackbox'

    scrape_interval: 30s

    scrape_timeout: 20s

    metrics_path: /probe

    params:

      module: [http_2xx]  # Look for a HTTP 200 response.

    file_sd_configs:

      - files:

        - /etc/prometheus/sites01.yml

        - /etc/prometheus/sites02.yml

    relabel_configs:

      - source_labels: [__address__]

        target_label: __param_target

      - source_labels: [__param_target]

        target_label: instance

      - target_label: __address__

        replacement: "blackbox_exporter:9115"  # Blackbox exporter.

###config alertmanager

receivers:

  - name: 'slack'

    slack_configs:

    - api_url: 'https://hooks.slack.com/services/...'

      send_resolved: true

      username: 'jcm'

      channel: '#alert'

      title: '[{{ .Status | toUpper }}{{ if eq .Status "firing" }}:{{ .Alerts.Firing | len }}{{ end }}] Notificações de Status - {{if eq .Status "firing"}}Site(s) OffLine!{{else}}Sites Sucessfull!{{end}} {{if eq .Status "firing"}}:fire:{{else}}:raised_hands:{{end}}'

      text: "{{ range .Alerts }}*Description:* {{.Annotations.description}}\n{{end}}

By adding labels to some alerts (which you can do in your alerting rules), and by matching on those labels in the "routes" section of your alertmanager config.

There are examples here and in the archives of this group.  Also, you may find this interactive routing tree editor/tester helpful:

what did you say i understand.

however there is the blackbox_exporter and the files site01.yml and site02.yml in file_sd_configs, I need each one to direct to an alert rule. then it is easy to target the alert rules matching the alertmanager routes.

You can set labels within the YAML or JSON files used by file_sd. See https://prometheus.io/docs/prometheus/latest/configuration/configuration/#file_sd_config

You could add a label in each file with two different values (so value 1 in file 1 and value 2 in file 2). You can then use that label in your alerting rules in a way that then allows you to direct the alerts as desired in the Alertmanager routing as mentioned.

I read the documentation, but I have no idea how to assemble this part.

would you have an example?

Assuming YAML your file is currently something like

targets:
  - target1
  - target2

You'd just add a labels section as well

labels:
  label1: value
  label2: value

So, in total

targets:
  - target1
  - target2

labels:
  label1: value
  label2: value

ok Stuart Clark, thanks for your help.

success, expected result.

the documentation does not make it clear which files to add.

I added the labels in each file:

site01.yml

- targets:

   site01.localhost

   labels:

     group: slack01

site02.yml

- targets:

   site02.localhost

   labels:

     group: slack02

in the alermanager file I added:

alermanager.yml

  routes:

   - receiver: slack01

     group_by: ['slack01']

    

   - receiver: slack02

     group_by: ['slack02']

[b.ca...@pobox.com]

- targets:

   site01.localhost

   labels:

     group: slack01

That's invalid.  "targets" is a list, so you need to mark the list items:

- targets:

    - site01.localhost

  labels:

    group: slack01

Also "labels" and "targets" must line up exactly.  In your post you had two characters before "targets" (dash and space) but you had three spaces before "labels".

yes friend you are right.

more in my file is right.

Here I ended up writing it wrong, I apologize.
