error reading snmp.yml file

[Andrew Meyer]

Hello, I seem to be seeing some errors with prometheus.

Nov  6 13:53:54 mon05 prometheus[17576]: time="2017-11-06T13:53:54Z" level=error msg="Error reading file \"/opt/monitoring/snmp_exporter/snmp.yml\": yaml: unmarshal errors:\n  line 1: cannot unmarshal !!map into []*config.TargetGroup" source="file.go:180"

Nov  6 13:53:59 mon05 prometheus[17576]: time="2017-11-06T13:53:59Z" level=error msg="Error reading file \"/opt/monitoring/snmp_exporter/snmp.yml\": yaml: unmarshal errors:\n  line 1: cannot unmarshal !!map into []*config.TargetGroup" source="file.go:180"

Nov  6 13:54:54 mon05 prometheus[17576]: time="2017-11-06T13:54:54Z" level=info msg="Checkpointing in-memory metrics and chunks..." source="persistence.go:539"

Nov  6 13:55:01 mon05 prometheus[17576]: time="2017-11-06T13:55:01Z" level=info msg="Done checkpointing in-memory metrics and chunks in 7.487848821s." source="persistence.go:563"

I just want to make sure this may or may not be a syntax issue in my config.

In my prometheus.service file I have it looking like this:

ExecStart=/opt/monitoring/prometheus/prometheus -config.file /opt/monitoring/configs/prometheus.yml

In the prometheus.yml file it looks like this:

  - job_name: 'juniper-snmp'

    file_sd_configs:

      - files: [ '/opt/monitoring/snmp_exporter/snmp.yml' ]

    metrics_path: /juniper-snmp

    params:

      module: [ juniper ]

    static_configs:

      - targets:

        - remote-ip

    relabel_configs:

      - source_labels: [__address__]

        target_label: __param_target

      - source_labels: [__param_target]

        target_label: instance

      - target_label: __address__

        replacement: prometheus-ip:9116

From what I can tell, you're trying to feed the snmp_exporter's config file as a target list to Prometheus.

The snmp.yml is a config file for the snmp_exporter, not a target list for Prometheus.

If you want to feed a list of target hosts/IPs to the SNMP exporter, you need to create a target list with the correct format:

Whoops.   Ok, thank you.  Removing for now.

Also,

Would it be best to break out the individual devices in separate job names?  Or could I set them all in one and specify snmp modules per devices?

Thank you!

[Ben Kochie]

Typically I template my config to have a job per type of device.

- job_name: snmp_if_mib

  params:

    module: [ if_mib ]

  static_configs:

    - targets:

      - some-cisco-switch

      - some-hp-switch

      - some-generic-router

- job_name: snmp_wifi_controller

  params:

    module: [ wifi_controller ]

  static_configs:

    - targets:

      - some-primary-wifi-controller

      - some-backup-wifi-controller

Ok.  So I generated my snmp.yml w/ Brocade, juniper, cisco, meraki, aruba.  I would then replace the module w/ the correct hardware type, right?  

What about the destination at the end?  I can specify that 1x correct?

Please remember to reply to all if there are multiple recipients.

Yes, the module param tells the exporter which SNMP walks/auth to use.

The metrics_path should always be `/snmp`

I'm not sure what you mean by the "destination at the end".  You will need to have separate jobs with all of the identical relabel_configs sections on each one.
