2023-04-06T14:44:38Z D! [outputs.file] Could not serialize metric: invalid name
2023-04-06T14:44:38Z D! [outputs.file] Wrote batch of 987 metrics in 10.518436ms

System info

telegraf-alpine:1.23.4 Docker container

Docker

No response

Steps to reproduce

Enable gRPC on Ciena device.
Start Telegraf.
This is similar to this issue (#6391).
Adding name_overide = "components" under [[inputs.gnmi]] helps allow the data to come in.
Specifying name = "components" under [[inputs.gnmi.subscription]] does not help.

Expected behavior

Write metrics to desired output using "components" as the measurement name.

Actual behavior

1.23.4

Can you please retry this on 1.26.1? There were a number of issues that were fixed since that release.

Getting following message with 1.26.1:

configuration issues as the response cannot be related to any subscription.

I have verified that this is also happening with another networking vendor as well (Juniper). Seem like the name paameter under [[inputs.gnmi.subscription]] is not being recognized for certain sensor paths.

For example, everything works fine when subscribing to /interfaces/interface but doesn't work properly when subscribing to /junos/system/linecard/cpu/memory.

@mohsin106 can you please paste the complete response data text so I can reproduce the issue!?

@srebhan I will post my complete Telegraf config and the debug output for my Juniper device since my Ciena device is unavailable but both have the same issue. Thank you for looking into this.

I do see these messages come in Wrote batch of 357 metrics in 2.163631m but nothing is writing to the database.

I suspect that the metric name is empty. Try to use data_format = "json" on the file output...

Yes, the name field is coming in blank.

{
	"fields": {
		"/components/component/properties/property/state/value": 0
	},
	"name": "",
	"tags": {
		"/components/component/properties/property/name": "mem-util-kernel-dfw-cntr-allocations-failed",
		"host": "telegraf-agent",
		"path": "/components/component/properties",
		"source": "juniperDevice1.mgt.cox.net",
		"tag-name": "FPC0:CPU0"
	},
	"timestamp": 1686245526
}

This is only happening with one sensor and I subscribe to multiple sensors. Is there a way to set the name field manually for just the memory sensor and not the other sensor?

This is my config with multiple sensor subscriptions:

[global_tags]
[agent]
  round_interval = true
  metric_batch_size = 1000
  metric_buffer_limit = 150000
  flush_interval = "10s"
  debug = true
  quiet = false
  hostname = "$containerName-telegraf-agent"
  omit_hostname = false

[[inputs.gnmi]]
  addresses = ["juniperDevice1.mgt.cox.net:50051",
	       "juniperDevice2.mgt.cox.net:50051",
	       "juniperDevice.3mgt.cox.net:50051"]
  username = "$user"
  password = "$password"
  encoding = "proto"
  redial = "10s"
  enable_tls = true
  tls_ca = "/etc/telegraf/router_ca.pem"
  insecure_skip_verify = false

  [[inputs.gnmi.subscription]]
    name = "memory"
    origin = "openconfig"
    path = "/junos/system/linecard/cpu/memory"
    subscription_mode = "sample"
    sample_interval = "60s"

  [[inputs.gnmi.subscription]]
    name = "microburst"
    origin = "openconfig"
    path = "/junos/system/linecard/qmon-sw"
    subscription_mode = "sample"
    sample_interval = "60s"

[[outputs.influxdb]]
  urls = ["http://10.20.30.40:8086"]
  database = "lab-qfx6-gnmi"
  timeout = "45s"

[[outputs.file]]
  files = ["stdout"]

@srebhan Since I'm providing the name parameter inside of [[inputs.gnmi.subscription]], should that force the name field to get assigned the value that I'm providing?

Yes. You either can either subscribe (as you did) or you create an additional alias for the spurious paths...

Subscribing as I did does not force the name field to be set to "memory".

@mohsin106 can you please post the message that fails!?

While Telegraf is starting up I see this warning messages when I subscribe to the memory sensor and then the data starts flowing in with name=""

Should the name field be set to "memory" since I'm doing this:

[[inputs.gnmi.subscription]]
    name = "memory"
    origin = "openconfig"
    path = "/junos/system/linecard/cpu/memory"
    subscription_mode = "sample"
    sample_interval = "60s"

Thanks @mohsin106! Will take a look tomorrow...

@mohsin106 hmmm the responsens you get are all prefixed with /components/component/... so you need an alias. It seems that your device returns spurious data with paths different from what you subscribe... I have tested using

[[inputs.gnmi]]
  addresses     = ["dummy"]
  redial        = "10s"

  [inputs.gnmi.aliases]
    memory = "/components"

  [[inputs.gnmi.subscription]]
    name = "memory"
    origin = "openconfig"
    path = "/junos/system/linecard/cpu/memory"
    subscription_mode = "sample"
    sample_interval = "60s"

and I get no warning. Of course you need to modify the config to your device but the important part is

  [inputs.gnmi.aliases]
    memory = "/components"

which assigns the metric name memory to every response coming from path /components/*... Can you give it a try!?

Yes. Using the [inputs.gnmi.aliases] parameter as you mentioned help eliminate those error message. So it seems like the issue is on the device end.?

Kind of. The issue is that Telegraf only knows the list of subscriptions. If a new response comes, we can only try to map the path to the subscriptions to find out the desired name. Your device (and it seems like Juniper devices in general) will spuriously report data with a path different to the one of the subscriptions... In this case, the lookup fails and we do not have any information to which subscription the response belongs.
Therefore, you need to help Telegraf to map the response path to a name. :-)

I will add a short readme section on Juniper devices...
