Generic config to create dynamic tag-mappings

[rostchri]

In my past issue "snmp v1 without bulkrequests for mikrotik" the last problem was that the ifDescr-oid contains the important information, which port-name should be remembered as tag for all the counter-variables pulled by influxsnmp so that this tag can be saved into influxdb as a variable to distinguish the counters and map it to the correct switch-ports.

You changed the code so that the ifDescr-information is fetched if a if-mib is used. I wonder if it would be possible to solve this kind of problem in a more generic way?

Because i now have the same problem if I want to collect informations about filesystems. Example:

HOST-RESOURCES-MIB::hrStorageIndex.31 = INTEGER: 31
HOST-RESOURCES-MIB::hrStorageIndex.38 = INTEGER: 38
HOST-RESOURCES-MIB::hrStorageIndex.42 = INTEGER: 42

HOST-RESOURCES-MIB::hrStorageType.31 = OID: HOST-RESOURCES-TYPES::hrStorageFixedDisk
HOST-RESOURCES-MIB::hrStorageType.38 = OID: HOST-RESOURCES-TYPES::hrStorageFixedDisk
HOST-RESOURCES-MIB::hrStorageType.42 = OID: HOST-RESOURCES-TYPES::hrStorageFixedDisk

OST-RESOURCES-MIB::hrStorageDescr.31 = STRING: /
HOST-RESOURCES-MIB::hrStorageDescr.38 = STRING: /zones
HOST-RESOURCES-MIB::hrStorageDescr.42 = STRING: /usr

HOST-RESOURCES-MIB::hrStorageAllocationUnits.31 = INTEGER: 1024 Bytes
HOST-RESOURCES-MIB::hrStorageAllocationUnits.38 = INTEGER: 4096 Bytes
HOST-RESOURCES-MIB::hrStorageAllocationUnits.42 = INTEGER: 1024 Bytes

HOST-RESOURCES-MIB::hrStorageSize.31 = INTEGER: 268363
HOST-RESOURCES-MIB::hrStorageSize.38 = INTEGER: 195212
HOST-RESOURCES-MIB::hrStorageSize.42 = INTEGER: 442618

I have > 100 filesystems in my systems and i'm interessted in the hrStorageSize and hrStorageAllocationUnits. To be able to use influxsnmp for that kind of task, influxsnmp needs to write the hrStorageDescr-information into influxdb.

How can that be achieved in a more generic (configurable) way?

Add this to the mib section:

index = hrStorageDescr

It should add an index tag to each entry.

That would be great but in fact it is not working:

[common]
httpPort = 8085
mibs     = HOST-RESOURCES-MIB
mibfile  = /tmp/influxsnmp.json
elapsed  = false


[snmp "smartos"]
host      = 192.168.178.15
community = secret
port      = 161
timeout   = 20
freq      = 30
version   = 2
retries   = 3
mibs      = storage


[mibs "storage"]
name = hrStorageSize
index = hrStorageDescr

[influx "*"]
url        = http://influxdb:8086
database   = snmp1

influxsnmp -config config.cfg -sample -verbose

And

...
[mibs "storage"]
regexp = hrStorage.*
index = hrStorageDescr
...

is'nt working neither.

[paulstuart]

Very odd -- it works great for me.

If you change it to be

name = hrStorageSize hrStorageDescr

Does it pick it up as a value?

Yes with:

[mibs "storage"]
name = hrStorageSize hrStorageDescr

With:

[mibs "storage"]
name = hrStorageSize hrStorageDescr
index = hrStorageDescr...

the output is reversed: At first the hrStorageSize - lines and then the hrStorageDescr - lines. The same output with

[mibs "storage"]
name = hrStorageDescr hrStorageSize
index = hrStorageDescr

[paulstuart]

It's not clear why it doesn't work for you. I'm going to have to meditate upon this....
