sqlserver "panic: Not implemented"

[biohazardxxx]

Relevant telegraf.conf:

[[inputs.sqlserver]]
  ## Specify instances to monitor with a list of connection strings.
  ## All connection parameters are optional.
  ## By default, the host is localhost, listening on default port, TCP 1433.
  ##   for Windows, the user is the currently running AD user (SSO).
  ##   See https://github.com/denisenkom/go-mssqldb for detailed connection
  ##   parameters.
  servers = [
    "Server=xxxxx.database.windows.net;Port=1433;User Id=telegraf;Password=xxxx;app name=telegraf;log=1;",      
   ]

  ## This enables a specific set of queries depending on the database type. If specified, it replaces azuredb = true/false and query_version = 2
  ## In the config file, the sql server plugin section should be repeated  each with a set of servers for a specific database_type.
  ## Possible values for database_type are  
  ## "AzureSQLDB" 
  ## "SQLServer"
  ## "AzureSQLManagedInstance"
  database_type = "AzureSQLManagedInstance"

  ## Optional parameter, setting this to 2 will use a new version
  ## of the collection queries that break compatibility with the original
  ## dashboards.
  ## query_version = 2

  ## If you are using AzureDB, setting this to true will gather resource utilization metrics
  ## azuredb = true

  ## If you would like to exclude some of the metrics queries, list them here
  ## Possible choices:
  ## - PerformanceCounters
  ## - WaitStatsCategorized
  ## - DatabaseIO
  ## - DatabaseProperties
  ## - CPUHistory
  ## - DatabaseSize
  ## - DatabaseStats
  ## - MemoryClerk
  ## - VolumeSpace
  # exclude_query = [ 'DatabaseIO' ]

Additional info:

It works ok with telegraf-1.16.1_windows_amd64

Same error with the new type of config as described on current README

  database_type = "AzureSQLManagedInstance"

  include_query = []
  exclude_query = ["SQLServerAvailabilityReplicaStates", "SQLServerDatabaseReplicaStates"]
  azuredb = true

Recent go-mssqldb(v0.10.0) might have a fix for this(https://github.com/denisenkom/go-mssqldb/pull/642)

[ghost]

This issue is reproduced at the SQL server with a self-signed certificate. As jjh75 mentions this issue could be fixed with an update to go-mssqldb(v0.10.0), it there any chances to have this fix in the next release?

I can confirm this issue is also present on linux and also solved for linux in the nightly build.
