Bug? in generator

[nicolas-gibelin]

Infos

• debian 9, manual install of prometheus
• snmp_exporter 0.9.0, 0.8.0
• In this issue, i use the PowerNet-MIB
• generator from git : * master abb143a Release 0.9.0
• go build : to compile the generator

generator.yml

  apcupssymmetrapx500:
    version: 1
    walk:
      - 1.3.6.1.4.1.318.1.1.1.9.3.3.1.16   # PhaseOutputPercentPower

Then

./generator generate

gives

snmp.yml

  - name: upsPhaseOutputPercentPower
    oid: 1.3.6.1.4.1.318.1.1.1.9.3.3.1.16
    type: gauge
    help: The percentage of the UPS power capacity in Watts at redundancy @ (n + x)
      presently being used on this output phase, or -1 if it's unsupported by this
      UPS. - 1.3.6.1.4.1.318.1.1.1.9.3.3.1.16
    indexes:
    - labelname: upsPhaseOutputPhaseTableIndex
      type: gauge
    - labelname: upsPhaseOutputPhaseIndex
      type: gauge

But the config does not work:

2 error(s) occurred:
* collected metric upsPhaseOutputPercentPower label:<name:"upsPhaseOutputPhaseIndex" value:"1" > label:<name:"upsPhaseOutputPhaseTableIndex" value:"1" > gauge:<value:40 >  was collected before with the same name and label values
* collected metric upsPhaseOutputPercentPower label:<name:"upsPhaseOutputPhaseIndex" value:"1" > label:<name:"upsPhaseOutputPhaseTableIndex" value:"1" > gauge:<value:42 >  was collected before with the same name and label values

After some tests, config (snmp.yml) must be (see the oid):

snmp.yml

  - name: upsPhaseOutputPercentPower
    oid: 1.3.6.1.4.1.318.1.1.1.9.3.3.1.16.1
    type: gauge
    help: The percentage of the UPS power capacity in Watts at redundancy @ (n + x)
      presently being used on this output phase, or -1 if it's unsupported by this
      UPS. - 1.3.6.1.4.1.318.1.1.1.9.3.3.1.16
    indexes:
    - labelname: upsPhaseOutputPhaseTableIndex
      type: gauge
    - labelname: upsPhaseOutputPhaseIndex
      type: gauge

And returns

upsPhaseOutputPercentPower{upsPhaseOutputPhaseIndex="1",upsPhaseOutputPhaseTableIndex="1"} 42
upsPhaseOutputPercentPower{upsPhaseOutputPhaseIndex="2",upsPhaseOutputPhaseTableIndex="1"} 42
upsPhaseOutputPercentPower{upsPhaseOutputPhaseIndex="3",upsPhaseOutputPhaseTableIndex="1"} 39

But

generator.yml

  apcupssymmetrapx500:
    version: 1
    walk:
      - 1.3.6.1.4.1.318.1.1.1.9.3.3.1.16.1   # PhaseOutputPercentPower

Then

./generator generate

Gives

FATA[0000] Cannot find oid '1.3.6.1.4.1.318.1.1.1.9.3.3.1.16.1' to walk  source="tree.go:162"

That sounds like your device is not implementing the MIB correctly. What does snmpwalk show for the OID?

[nicolas-gibelin]

Hi, ``` snmpwalk -v 1 -c public hostname 1.3.6.1.4.1.318.1.1.1.9.3.3.1.16 PowerNet-MIB::upsPhaseOutputPercentPower.1.1.1 = INTEGER: 39 PowerNet-MIB::upsPhaseOutputPercentPower.1.1.2 = INTEGER: 39 PowerNet-MIB::upsPhaseOutputPercentPower.1.1.3 = INTEGER: 37 oid version of result: .1.3.6.1.4.1.318.1.1.1.9.3.3.1.16.1.1.1 = INTEGER: 40 .1.3.6.1.4.1.318.1.1.1.9.3.3.1.16.1.1.2 = INTEGER: 39 .1.3.6.1.4.1.318.1.1.1.9.3.3.1.16.1.1.3 = INTEGER: 38 ``` ``` snmpwalk -v 1 -c public hostname 1.3.6.1.4.1.318.1.1.1.9.3.3.1.16.1 PowerNet-MIB::upsPhaseOutputPercentPower.1.1.1 = INTEGER: 40 PowerNet-MIB::upsPhaseOutputPercentPower.1.1.2 = INTEGER: 38 PowerNet-MIB::upsPhaseOutputPercentPower.1.1.3 = INTEGER: 37 ``` ``` snmpwalk -v 1 -c public hostname 1.3.6.1.4.1.318.1.1.1.9.3.3.1.16.1.1 PowerNet-MIB::upsPhaseOutputPercentPower.1.1.1 = INTEGER: 40 PowerNet-MIB::upsPhaseOutputPercentPower.1.1.2 = INTEGER: 38 PowerNet-MIB::upsPhaseOutputPercentPower.1.1.3 = INTEGER: 37 ``` The 3 walks return the same.. If you think this is a bug in MIB/Hardware, i can patch the MIB file.

Yes, this is a bug in the hardware. That first 1 shouldn't be there. You should file a bug with your vendor.

[nicolas-gibelin]

Thanks for the answer

Regards.

@nicolas-gibelin , did the vendor fix the bug?

[nicolas-gibelin]

Hi, no, so i made a script to patch the file generated bu 'generator' Nicolas Gibelin

@nicolas-gibelin , what the vendor said about "device bug"? Did he confirm that? What was the reason not to fix a bug? Thank you!

[nicolas-gibelin]

the vendor never answered. But it's probably really a bug because we bought it new devices with differents mibs and we had no issue with generator. Best Regards. Nico Nicolas Gibelin
