Telegraf and hrStorageTable

Hi. I want to monitor the size of the each storage areas in my hosts. I used the following config in order to get all entries of the hrStorageTable:

[[inputs.snmp]]
  agents = ["myhost:161"]
  timeout = "5s"
  retries = 3
  version = 2
  community = "community"
  max_repetitions = 10

  [[inputs.snmp.field]]
    name = "host"
    oid = "SNMPv2-MIB::sysName.0"
    is_tag = true

  [[inputs.snmp.table]]
    name = "hrStorage"
    oid = ".1.3.6.1.2.1.25.2.3"
    inherit_tags = ["host"]

    [[inputs.snmp.table.field]]
      name = "hrStorageDescr"
      oid = "HOST-RESOURCES-MIB::hrStorageDescr"
      is_tag = true

After running the test, I’m able to retrieve the metrics:

> hrStorage,agent_host=myhost,host=myhost,hrStorageDescr=/boot,hrStorageIndex=36 hrStorageAllocationUnits=1024i,hrStorageSize=495844i,hrStorageType=".1.3.6.1.2.1.25.2.1.4",hrStorageUsed=156149i 1538709806000000000
> hrStorage,agent_host=myhost,host=myhost,hrStorageDescr=/home,hrStorageIndex=38 hrStorageAllocationUnits=4096i,hrStorageSize=18007380i,hrStorageType=".1.3.6.1.2.1.25.2.1.4",hrStorageUsed=156036i 1538709806000000000
> hrStorage,agent_host=myhost,host=myhost,hrStorageDescr=/,hrStorageIndex=31 hrStorageAllocationUnits=4096i,hrStorageSize=16641962i,hrStorageType=".1.3.6.1.2.1.25.2.1.4",hrStorageUsed=11430053i 1538709806000000000

After doing that, I want to create a graph in grafana.

But when I try to find the fields I can’t find them in the drop down and I don’t have data points. Is there something I’m missing? Any help will be appreciated.

Thanks!

When Telegraf runs with the --test flag it doesn’t send the data to the outputs, maybe this is what is happening?

I know that. Please read my question.
Thanks.

Found my issues. I was creating a new measurement, as you can see here:

  [[inputs.snmp.table]]
    name = "hrStorage"
    oid = ".1.3.6.1.2.1.25.2.3"
    inherit_tags = ["host"]

    [[inputs.snmp.table.field]]
      name = "hrStorageDescr"
      oid = "HOST-RESOURCES-MIB::hrStorageDescr"
      is_tag = true

And I was using snmp in grafana, that’s why I was not able to find anything.
