Error when scraping: "...same name and label values"

What device/snmpwalk OID are you using?

1.3.6.1.4.1.318.1.1.1.9.3.3.1.8

If this is a new device, please link to the MIB(s):

MIB

What did you do that produced an error?

I followed the procedures for generating and using the snmp_exporter to gather snmp metrics.

I used the generator to generate a snmp.yml file - the generator.yml file contains:

modules:
ups_mibs:
    walk:
      - 1.3.6.1.4.1.318.1.1.1.9.3.3.1.8
 version: 3  
    auth:

The snmp.yml file:

ups_mibs:
  walk:
  - 1.3.6.1.4.1.318.1.1.1.9.3.3.1.8
  metrics:
  - name: upsPhaseOutputMaxLoad
    oid: 1.3.6.1.4.1.318.1.1.1.9.3.3.1.8
    type: gauge
    help: The maximum output load in VA measured since the last reset (upsPhaseResetMaxMinValues),
      or -1 if it's unsupported by this UPS - 1.3.6.1.4.1.318.1.1.1.9.3.3.1.8
    indexes:
    - labelname: upsPhaseOutputPhaseTableIndex
      type: gauge
    - labelname: upsPhaseOutputPhaseIndex
      type: gauge
  version: 3
  auth:
    community: public
    security_level: authPriv
    username: <redacted>
    password: <redacted>
    auth_protocol: MD5
    priv_protocol: DES
    priv_password: <redacted>

Then running snmp and prometheus in a docker-compose file (in notes section below), I used the following link to view the scrape data from Prometheus
http://localhost:9116/snmp?module=ups_mibs&target=<redacted>

What did you expect to see?

I expected to see three values one for each phase of power from the device with the OID above.

What did you see instead?

An error has occurred during metrics gathering:

2 error(s) occurred:
* collected metric upsPhaseOutputMaxLoad label:<name:"upsPhaseOutputPhaseIndex" value:"1" > label:<name:"upsPhaseOutputPhaseTableIndex" value:"1" > gauge:<value:27280 >  was collected before with the same name and label values
* collected metric upsPhaseOutputMaxLoad label:<name:"upsPhaseOutputPhaseIndex" value:"1" > label:<name:"upsPhaseOutputPhaseTableIndex" value:"1" > gauge:<value:25660 >  was collected before with the same name and label values

I ran a snmpwalk and see that the correct values are returning from the device:

snmpbulkwalk -v3  -On -t 60 -u <redacted> -l authPriv -a MD5 -A <redacted> -x DES -X <redacted> -M /usr/share/snmp/mibs/ -m all u<redacted> upsPhaseOutputMaxLoad


.1.3.6.1.4.1.318.1.1.1.9.3.3.1.8.1.1.1 = INTEGER: 23010
.1.3.6.1.4.1.318.1.1.1.9.3.3.1.8.1.1.2 = INTEGER: 27280
.1.3.6.1.4.1.318.1.1.1.9.3.3.1.8.1.1.3 = INTEGER: 25660

Notes:

Here is the prometheus.yml section:

global:
  scrape_interval: 65s
  scrape_timeout: 60s
# looking at location of rules files relative to docker-compose.yml
#rule_files:
 #- 'prometheus.rules'

scrape_configs:

 - job_name: 'ups_lond_snmp'
   metrics_path: /snmp
   params:
     module: [ups_mibs]
   static_configs:
     - targets: [
     '<redacted>'
     ]
   relabel_configs:
     - source_labels: [__address__]
       target_label: instance
       regex: '(^[^-]*-[^.]*).*'
       replacement: '$1'

     - source_labels: [__address__]
       target_label: __param_target

     - target_label: __address__
       replacement: <redacted>:9116  # SNMP exporter

And the docker-compose.yml file, which should help with running this:

version: '3.3'

 volumes:
   prometheus_data: {}
   grafana_data: {}

 services:

   prometheus:
     image: prom/prometheus:latest
     volumes:
       - ./prometheus/:/etc/prometheus/
       - prometheus_data:/prometheus
       - /home/user/prometheus_snmp/certs/:/etc/ssl/certs/:z
     command:
       - '--config.file=/etc/prometheus/prometheus.yml'
       #- '--storage.tsdb.path=/data'
     expose:
       - 9090
     ports:
       - "9090:9090"
     network_mode: "host"
     depends_on:
       - snmp-exporter

   snmp-exporter:
     image: prom/snmp-exporter:master
     volumes:
       - ./snmp_exporter/:/etc/snmp_exporter/
     expose:
       - 9116
     ports:
       - "9116:9116"
     network_mode: "host"

I've also read through the issues and google Groups but cannot determine if this is a configuration error on my part or a bug in the snmp_exporter.

That's a device bug, that snmpwalk output doesn't match the MIB - there's an extra oid in there.
You'll need to take this up with your vendor.

[laughland]

Will do, thanks for the quick reply.

[bissquit]

@laughland , did the vendor fix the bug? Could you say please what device and firmware version do you use?
