Raw Blame History

# `hyperv` collector
The collector reads 16 `Hyper-V ...` PDH objects with `pdh.CounterTypeRaw`
from its sub-collectors, plus HCS, WMI and `virtdisk.dll` data. The objects
exist only where the Hyper-V role is installed; CI does not provision it.
Almost all objects are multi-instance; `Hyper-V Virtual Machine Health Summary`
is single-instance. These notes were recorded on Windows Server 2025 build
26100 with one running Generation 2 VM (`ubuntu`, 6 vCPUs, 2 GiB static
memory) on a host with 12 logical processors.
- `pdh.InstancesAll` drops the `_Total` instance, so the processor objects
return `Hv LP 0`..`Hv LP 11`, `Root VP 0`..`Root VP 11` and
`ubuntu:Hv VP 0`..`ubuntu:Hv VP 5`. The host logical processor count is the
number of `Hv LP` instances (12 here).
- Hypervisor processor objects: every `%` counter and `CPU Wait Time Per
Dispatch` is `PERF_PRECISION_100NS_TIMER`. The raw value is cumulative time
in 100 ns ticks. On a logical processor `% Idle Time` + `% Total Run Time`
equals the time since boot (453 s after a 452.7 s uptime), and
`% Total Run Time` is about `% Guest Run Time` + `% Hypervisor Run Time`.
The help text of `CPU Wait Time Per Dispatch` and `I/O TLB Flush Cost` says
"average time (in nanoseconds)", but the raw value is cumulative 100 ns
ticks. `internal/pdh` already scales `PERF_PRECISION_100NS_TIMER` to
seconds, so do not scale again. Publish both as `_seconds_total` counters
next to their operation count (`Logical Processor Dispatches/sec`,
`I/O TLB Flushes/sec`), so the average is a ratio of the two rates.
- The virtual processor `state` label is `hypervisor`, `guest`, `remote` for
VMs and `guest_run`, `hypervisor`, `remote` for root VPs. There is no idle
state.
- `Hyper-V Hypervisor Root Partition` is read for the instance `Root` only.
All its non-`/sec` counters are `PERF_COUNTER_LARGE_RAWCOUNT`. Page counts
and sizes are gauges; by the help text `Skipped Timer Ticks` and
`Device Interrupt Throttle Events` count events, so they are counters.
- Dynamic Memory: memory counters are in MB (`Physical Memory` and
`Guest Visible Physical Memory` are 2048 for the 2 GiB VM). `Added Memory`
and `Removed Memory` are cumulative MB, `Memory Add/Remove Operations` are
cumulative counts. Pressure counters are percentages and exceed 100
(145 here). The VM instance exists even with Dynamic Memory disabled.
Instances are VM names; VMs of the Host Compute Service (WSL 2) have an
empty instance name.
- `Hyper-V DataStore`: instances are `<VM GUID> <file kind>` with the kinds
`configuration file`, `runtime file`, `worker process configuration` and
`worker process runtime state`. Every counter is
`PERF_COUNTER_LARGE_RAWCOUNT` and the help text only repeats the name. The
`... count` counters are cumulative. The `... latency microseconds`
counters are not cumulative: `Commit operation latency microseconds` of the
configuration file dropped from 6659 to 5213 while `Commit operation count`
stayed 1.
- `Hyper-V VM Vid Partition`: pages are 4 KiB. The 2 GiB VM had 526336
`Physical Pages Allocated`.
- `Hyper-V Virtual Storage Device`: instances are the disk path with `\`
replaced by `-` and `(...)` by `[...]`, for example
`C:-ProgramData-Microsoft-Windows-Virtual Hard Disks-ubuntu.vhdx`; a `\\?\`
prefix becomes `--?-` (the `.vmgs` guest state file). A DVD drive shows up
as `ISO`. Only running VMs have instances.
- `Latency`, `Lower Latency`, `Queue Length` and `Lower Queue Length` all
had the same raw value (56686): the sum of IO latencies in 100 ns ticks.
The base of `Latency` (10) equals the raw `Throughput` and
`Read Count` + `Write Count` (6 + 4).
- `Throughput` (`PERF_COUNTER_COUNTER`) counts IO transfers.
`Normalized Throughput` (`PERF_COUNTER_BULK_COUNT`) counts 8 KB IO
transfers by its help text. Both raw values are cumulative, as is
`Io Quota Replenishment Rate` (`PERF_COUNTER_BULK_COUNT`); publish them
as counters.
- `Read Count`, `Write Count` and `Error Count` are
`PERF_COUNTER_RAWCOUNT` but cumulative ("total number of ...").
- `Hyper-V Virtual Switch` and `Hyper-V Virtual Network Adapter`: all
`/sec` counters are `PERF_COUNTER_BULK_COUNT`, so the raw value is a
cumulative count. `Bytes/sec` is `Bytes Received/sec` + `Bytes Sent/sec`
and `Packets/sec` is `Packets Received/sec` + `Packets Sent/sec` in the
samples. Switch instances are the switch names (`External`, `Internal`).
VM adapter instances are `<VM>_<adapter>_<VM GUID>--<GUID>`. Host side
instances look like `Internal_<GUID>`, `Ethernet_<GUID>`,
`DrPort <GUID>_<GUID>` and
`Microsoft Hyper-V Network Adapter__DEVICE_{<GUID>}`. The collector uses
them unchanged as `adapter`.
- `Hyper-V Virtual Network Adapter Drop Reasons` has the same instances as
`Hyper-V Virtual Network Adapter`. Every counter is a cumulative
`PERF_COUNTER_LARGE_RAWCOUNT`; only `Outgoing NotReady` was non-zero (9).
- `Hyper-V Replica VM` exists but had no instance (no replication).
By the help text `Replication Latency` and `Average Replication Latency`
are in seconds, the size counters in bytes, and `Replication Count`,
`Network Bytes Sent/Recv` and `Resynchronized Bytes` are cumulative since
VMMS start.
- `Hyper-V Virtual SMB` and `Hyper-V Legacy Network Adapter` had no
instances (no SMB-backed VM storage, no legacy adapter). In Virtual SMB,
`Tree Connect Count` is `PERF_COUNTER_COUNTER` but its help text says
"the current number of Tree Connects".
- `Hyper-V Virtual Machine Health Summary` counts VMs: `Health Ok` was 1 for
the one VM.
- The `wmi_health`, `virtual_hard_disk` and host VM processor metrics do not
come from PDH, so the table below does not cover them.
- To test emitted metrics without Hyper-V, build the descriptors with the
`build...Descriptors` helpers, fill the `perfDataObject...` slice (or a
`pdhtypes.Collector` fixture) and gather through a registry, as in
`hyperv_metric_types_internal_test.go`.
## Counter reference
Recorded on Windows Server 2025 (build 26100). `Raw` and `Base` are the first and second
values that `pdh.CounterTypeRaw` returns for the sample instance.
