To migrate an instance to a new region, do the following:
az group delete -y GROUP_NAME)If you try deleting the resource group and moving to a different region without the above procedure, you’ll get an error like this:
"The workspace name 'logs-wb-XXXX' is not unique"
Full, official instructions for deleting a Log Analytics Workspace can be found here. Review this page before continuing.
To summarize, you need your subscription ID, resource group name, log analytics workspace name, and a valid bearer token, to authenticate a REST API (only!) DELETE request.
To quickly, manually get a bearer token, you can go to any Azure REST API documentation page with a green “Try It” button. For example, this one.
Click “Try It”, authenticate, and you will find a valid Authorization header
in the “Preview” section at the bottom of the “REST API Try It” pane. Copy the
entire header value (i.e. Authorization: Bearer <base64-bearer-token-data>).
Remember, this is a credential (and will expire), so do not log it, track it in
version control, &c.
You can then edit the following bash script template (or equivalent) to permanently delete the workspace:
#!/usr/bin/env bash
# Set to the value copy-pasted from the Try It pane, like:
# "Authorization: Bearer ${BEARER}"
AUTH_H='<copied-authorization-header>'
# Set these variables using values from your resource group.
SUBSCRIPTION='<subscription-id>'
RESOURCE_GROUP='<resource-group-name>'
WORKSPACE_NAME='<log-analytics-workspace-name>'
# Does not need to be edited.
URL="https://management.azure.com/subscriptions/${SUBSCRIPTION}/resourcegroups/${RESOURCE_GROUP}/providers/Microsoft.OperationalInsights/workspaces/${WORKSPACE_NAME}?api-version=2015-11-01-preview&force=true"
# Requires the cURL command.
curl -X DELETE -H "${AUTH_H}" "${URL}"
