Converting SNMP Octet String to usable data.

I have snmp_exporter running and I am able to get data. Issue I'm having is some of the data is coming as an Octet String

Object in MIB file

fanSpeed OBJECT-TYPE

SYNTAX OCTET STRING

ACCESS read-only

STATUS mandatory

DESCRIPTION

"Fan speed expressed in percent(%) of maximum RPM.

An octet string expressed as 'ddd% of maximum' where:

d is a decimal digit or blank space for a leading zero.

If the fan is determined not to be running or

the fan speed cannot be determined, the string will

indicate 'Offline'."

::= { fanEntry 3 }

Data reported by snmp_exporter

# HELP fanSpeed Fan speed expressed in percent(%) of maximum RPM - 1.3.6.1.4.1.2.3.51.3.1.3.2.1.3
# TYPE fanSpeed gauge
fanSpeed{fanIndex="1",fanSpeed="0x20333225206F66206D6178696D756D"} 1
fanSpeed{fanIndex="2",fanSpeed="0x20333225206F66206D6178696D756D"} 1
fanSpeed{fanIndex="3",fanSpeed="0x20333225206F66206D6178696D756D"} 1
fanSpeed{fanIndex="4",fanSpeed="0x20333225206F66206D6178696D756D"} 1
fanSpeed{fanIndex="5",fanSpeed="0x20333125206F66206D6178696D756D"} 1

How do I convert/extract the fan speed percentage?

What you want to do is hack the MIB for the syntax to be DisplayString instead as it sounds to be ASCII, and then use regex_extracts feature to pull out the number(s).

Related, there's an issue open to make it easier to override. I worked up a crappy patch, but it needs cleanup before we can merge it.

https://github.com/prometheus/snmp_exporter/issues/186

https://github.com/prometheus/snmp_exporter/pull/263

Once that's in, it'll be easier to deal with this mapping in the generator.

Do you have an example? I did run 0x20333225206F66206D6178696D756D thru a hex to text convert and get the result 32% of maximum

If I strip of the "0x" and "25206F66206D6178696D756D" I'm left with "203332" which converts to 32 which is the reported fan speed %. The other fan running at a different speed converted the same way.

Is there a way in prometheus or graphana to convert the hex into a usable number/string?

If you could share the snmp.yml config for that metric, we could point you in the right direction.

That is a different thing. Please make sure you're using the latest version of the generator and exporter.

I do use snmp_exporter-0.9.0.linux-amd64 and latest generator.
Not sure how to represent the data in a human readable format.

Try the config from here: https://github.com/SuperQ/tools/tree/master/snmp_exporter/ibm

I think that should do what you need.

Note, this is generated from a slightly patched generator. It includes a labeling change[0], and an overrides change[1].

Neither of these two patches are official (yet).

Coming back to re-visit this issue. I have update to the latest snmp_exporter 0.12.0 and updated the generator. I still have the issue with the octet string data. Has there been any progress on how the information can be extracted?

Hey, did you ever find a solution to this? I think I'm having the same issue. The values I need are all in a label as OctetString in hex. Using regex_extracts as suggested does not seem to help.

Is the MIB for this publicly accessible?

Yeah I downloaded from here, http://www.techhelp24.net/download/brocade/FOS/MIB/v7.4.1d_all_mibs.tar.gz

Using FA-EXT-MIB

swSfpTemperature OBJECT-TYPE

STATUS current

DESCRIPTION "This object identifies the temperature of SFP"

::= { swSfpStatEntry 1 }

swSfpVoltage OBJECT-TYPE

SYNTAX OCTET STRING (SIZE(8))

UNITS "milli voltage"

MAX-ACCESS read-only

STATUS current

DESCRIPTION "This object identifies the voltage of SFP."

::= { swSfpStatEntry 2 }

swSfpCurrent OBJECT-TYPE

SYNTAX OCTET STRING (SIZE(8))

UNITS "milli amphere"

MAX-ACCESS read-only

STATUS current

DESCRIPTION "This object identifies the current of SFP."

::= { swSfpStatEntry 3 }

swSfpRxPower OBJECT-TYPE

SYNTAX OCTET STRING (SIZE(8))

UNITS "dBm"

MAX-ACCESS read-only

STATUS current

DESCRIPTION "This object identifies the Rx power consumption of SFP."

::= { swSfpStatEntry 4 }

swSfpTxPower OBJECT-TYPE

Can you provide a sample snmpwalk of this so I have a better idea on what the real data looks like?

Don't worry, after finding the example here, I made a slight change to my regex:

^(?:(\d+).*)$

Which works beautifully!

Thanks for your time.
