MetadataNoToken |
The number of times the instance metadata service was accessed without a token (IMDSv1). This metric helps identify workloads that have not yet migrated to IMDSv2. |
[Fleet] [ImageBuilder] [AppBlockBuilder] |
Sum | Count |
MetadataNoTokenRejected |
The number of times an IMDSv1 request to the instance metadata service was rejected. This metric is available when the instance is configured to require IMDSv2. |

Sum | Count |
Note
The following metrics are available for all operating systems except
Windows Desktop: UDPPacketLossRate, TCPRetransmissionRate,
BandwidthInbound, CongestionWindow,
ConnectionDuration, MetadataNoToken, and
MetadataNoTokenRejected. All metrics are available for
Windows Server operating system. None of the metrics are available
for Windows Desktop operating system.
