The following valid ARM syntax

                }
            }
        ]
    }

Written as follows in PSArm

Resource (concat 'test' '/Microsoft.Insights/diagnosticSettings') -Namespace 'Microsoft.Network' -Type 'applicationGateways/providers/diagnosticSettings' -ApiVersion '2017-05-01-preview' -Location (resourceGroup).location {

      workspaceId concat '/subscriptions/' (subscription).subscriptionId '/resourceGroups/' (resourceGroup).name '/providers/microsoft.operationalinsights/workspaces/' 'test'
      logs {
        category 'ApplicationGatewayAccessLog'
        enabled $true
        retentionPolicy {
          enabled $false
          days 0
        }
      }
      logs {

        enabled $true
        retentionPolicy {
          days 0

        }
      }
      logs {

        enabled $true
        retentionPolicy {
          days 0
          enabled $false
        }
      }
      metrics {
        category 'AllMetrics'
        enabled $true
        retentionPolicy {
          enabled $false
          days 0
        }
      }
    }
    DependsOn @(

  }
