Configuring azure_monitor output plugin in telegraf

Telegraf
1

Hi,
I have installed telegraf and started service on my local linux machine and i wanted to send data to azure monitoring using “outputs.azure_monitor” output plugin in telegraf configuration file. can someone guide me what fields need to be changes in “outputs.azure_monitor” plugin considering telegraf is not installed on azure VM’s.

[[outputs.azure_monitor]]

Timeout for HTTP writes.

timeout = “20s”

Set the namespace prefix, defaults to “Telegraf/”.

namespace_prefix = “Telegraf/”

Azure Monitor doesn’t have a string value type, so convert string

fields to dimensions (a.k.a. tags) if enabled. Azure Monitor allows

a maximum of 10 dimensions so Telegraf will only send the first 10

alphanumeric dimensions.

strings_as_dimensions = false

Both region and resource_id must be set or be available via the

Instance Metadata service on Azure Virtual Machines.

Azure Region to publish metrics against.

ex: region = “southcentralus”

region = “”

The Azure Resource ID against which metric will be logged, e.g.

ex: resource_id = “/subscriptions/<subscription_id>/resourceGroups/<resource_group>/providers/Microsoft.Compute/virtualMachines/<vm_name>”

resource_id = “”

Optionally, if in Azure US Government, China, or other sovereign

cloud environment, set the appropriate REST endpoint for receiving

metrics. (Note: region may be unused in this context)

endpoint_url = “https://monitoring.core.usgovcloudapi.net”

sorry, for late reply @Anaisdg . I have went through the document, and made changes as.
I have added AZURE_TENANT_ID,AZURE_CLIENT_ID,AZURE_CLIENT_SECRET in my environmental variables as per plugins page,
