DOCA Telemetry Utils
Examples
- "Which diagnostic counters does this BlueField actually
expose?" — this is in scope. Enumerate then probe; do
not start a collector app here.
- "My exporter names
port_rx_bytes but nothing shows up
downstream." — translate name to Data ID and probe
per-device support before changing the exporter.
Quick triage: the exporter ships, the collector sees nothing
doca_telemetry_utils get-counters: is the counter known to this release?
doca_telemetry_utils <counter>: print its property options.
doca_telemetry_utils <counter> <properties>: resolve the Data ID.
doca_telemetry_utils <device PCI> <counter> <properties>: "not
supported" on this device means the exporter drops it silently; do not
commit that counter.
doca_telemetry_utils <0x... Data ID>: reverse-resolve an ID captured on
the wire.
- Check host and BlueField release pairing with
doca-version.
- If every step resolves cleanly, hand off to
doca-telemetry ## debug.
Quote the tool's output verbatim; never construct Data IDs by hand.
Instructions
Follow Loading order below. Open the tasks companion for
install / run / test. Open the capabilities companion for
schema discovery and pairing with the telemetry libraries.
Do not open every companion file.
Where to start: This is a tool skill for invoking
doca_telemetry_utils — the documented host-side CLI that
supports a DOCA Telemetry exporter / collector pipeline by
discovering the counter schema, translating counter names ↔
Data IDs, and probing per-device counter support. Open
the tasks companion and start at
## install for the host-side
prerequisites and ## run for the
three documented invocation classes
(enumerate / name→ID / ID→name). Open
the capabilities companion when the question is
what does this tool actually discover about the telemetry
schema, how does it pair with the developer-side
doca-telemetry and
exporter libraries, how do I confirm a device supports a
counter before committing an exporter config to it, or
why does my exporter pipeline silently drop a metric.
How to use this skill. Read this file, then search the companion file
for the ## <name> heading the question needs and read that whole section.
Answer completely from it, quoting only its symbols and commands. Do not
browse docs; use the entry points in doca-public-knowledge-map. Give
environment checks as commands for the user's DOCA host. For out-of-scope
requests, name the skill that owns them and stop.
This skill is the operator-side support tool for a
DOCA Telemetry deployment. It is NOT the developer-side
collector library (that is
doca-telemetry),
NOT the developer-side publisher library (that is
doca-telemetry-exporter — see
doca-telemetry ## Related skills),
and NOT a DOCA Telemetry Service (DTS) deployment guide
(route to doca-dts).
Three separate surfaces; conflating them is the most
common telemetry first-touch error.
Example questions this skill answers well
The CLASSES of doca_telemetry_utils questions this skill
is built to answer, each with one worked example. The
class is the load-bearing piece; the worked example is one
instance.
- "My exporter says it's emitting
port_rx_bytes but
nothing shows up downstream — what did I get wrong?" —
worked example: "my exporter config has a counter name
string and my collector sees no events with that
name". Answered by the name ↔ Data ID translation
step in
the capabilities companion
- the per-device-support probe in
the tasks companion: the exporter
ships a Data ID, not a name; a name in the config that
resolves to a Data ID the device does not support is
silently dropped.
- "Which DOCA diagnostic counters does this BlueField
actually expose?" — worked example: "enumerate the
full counter schema for my BlueField-3 before I write
the exporter config". Answered by the schema-discovery
invocation class in
the capabilities companion
(
doca_telemetry_utils get-counters lists every
counter name the diagnostic-data surface knows about;
pair with a per-device probe to confirm support).
- "I have a Data ID in a captured log — what counter
was that?" — worked example: "a downstream consumer
emitted
Data ID: 0x1160000600030201 — translate it
back so I can correlate against the public guide".
Answered by the reverse-resolve invocation class in
the capabilities companion
- the
ID-encodes-properties rule in
the tasks companion (a Data ID carries
the counter's property dimensions; the reverse-resolve
reports them).
- "What property dimensions does this counter take and
what values are valid?" — worked example: "I know
the counter is
pcie_link_write_stalled_time_* — what
do node / pcie_index / depth mean and what
values does the device accept?". Answered by the
property-dimension table in
the capabilities companion
- the
<name> invocation without arguments which
prints the documented property options + units +
unit-specific axes.
- "Is this counter supported on this device before I
commit it to the exporter config?" — worked example:
"validate that
port_rx_bytes with node=1 is
exposed on the BlueField at PCIe address X before I
write the exporter config". Answered by the
per-device-support probe (<device PCI> <name> [properties]) in
the capabilities companion
- the gate-before-commit rule in
the tasks companion.
- "Is
doca_telemetry_utils on my install, and is it
paired with the matching doca-telemetry library
version?" — worked example: "is the diagnostic-
data counter set my exporter targets on this DOCA
version?". Answered by the version-overlay in
the capabilities companion,
which redirects to the canonical
doca-version chain
and adds the tool ↔ doca-telemetry library
schema-version match rule.
When to load this skill
Load this skill when the user is — or the agent needs
to — invoke doca_telemetry_utils on a real host with
DOCA installed, alongside an exporter / collector
pipeline that needs schema discovery, per-device
support validation, or Data ID translation.
Concretely:
- Enumerating the full counter schema before writing
a fresh DOCA Telemetry exporter config (
get-counters).
- Validating that a chosen counter + property set
resolves to a Data ID the target device actually
supports, before committing the config.
- Reverse-resolving a Data ID captured from a
downstream consumer back to a counter name +
properties for correlation against the public guide.
- Debugging a "exporter ships, collector receives
nothing" report (the canonical schema-mismatch /
unsupported-counter failure mode).
- Producing a "validated counter set for this
BlueField + this DOCA version" artifact as part of
a structured exporter-config baseline.
- Migrating an exporter pipeline across DOCA versions
and confirming each previously-supported counter
still resolves cleanly on the new version.
Do not load this skill for general DOCA orientation,
collector / exporter library programming, DTS
deployment, or DOCA install. For those, route to
doca-public-knowledge-map,
doca-telemetry,
or doca-setup.
What this skill provides
This is a thin loader. Substantive material lives
in two companion files:
- the capabilities companion — what
doca_telemetry_utils
discovers + how it pairs with the developer-side
surfaces: the three documented invocation classes
(enumerate / name→ID / ID→name), the property-
dimension model (counters carry property axes such
as node, pcie_index, depth, plus per-unit
axes), the optional per-device capability probe
(<device PCI> <name> runs the resolved counter
against the device), the operator-side support
role (this is NOT the developer-side library; it
exists to make exporter / collector setups
honest), the version overlay (tool ↔
doca-telemetry library schema version pairing),
the layered error taxonomy (install / parse /
unknown-counter / unknown-data-id / property-out-
of-range / device-not-supported / version /
cross-cutting), the observability surface
(stdout-only), and the safety policy (the tool is
read-only; mistakes appear downstream as silent
metric drops, not crashes).
- the tasks companion — step-by-step workflows for the
in-scope task verbs:
install (host-side DOCA +
telemetry component prerequisites), configure
(axis decisions: which invocation class, which
device, which counter), build (route to install
— the binary is shipped), modify (refuse — do
not patch the binary; modify the invocation and
the exporter / collector config that consumes the
resolved Data IDs), run (the three documented
invocations), test (round-trip a chosen
counter through name → Data ID → per-device
probe → exporter config → collector receipt),
debug (walk the error taxonomy), use (the
hand-off into the developer-side doca-telemetry
collector / exporter pipeline), plus a Deferred task verbs block.
The skill assumes a host where DOCA is already
installed with the telemetry component, a BlueField
the operator is targeting is visible to DOCA, and the
exporter / collector pipeline that consumes the
resolved Data IDs is either being authored or has
already been authored against the matching
doca-telemetry
library version.
What this skill deliberately does not ship
This skill is agent guidance, not a samples or
scripts bundle. To keep the boundary clean, it
deliberately does not contain — and pull requests
should not add:
- A verbatim counter inventory or Data ID
table. The counter set evolves across DOCA
versions and BlueField generations; an
inventory pinned in this skill would silently rot.
doca_telemetry_utils get-counters on the
installed binary is the authoritative source.
- Pre-baked exporter / collector configs. Configs
are install-, device-, and use-case-specific; a
packaged config in this skill would mislead
operators on a different setup.
- A DTS deployment recipe. DTS is a separate DOCA
service with its own public guide; route via
doca-public-knowledge-map.
This skill resolves the counter names + IDs a
DTS pipeline consumes; it does not configure DTS.
- Wrappers, parsers, or scripts in any language
that consume the tool's output. The output is a
simple text mapping; users who want to script
against it should read the live guide and write
the parser against their installed version.
- A
samples/ or reference/ subtree. This is
a thin loader for a shipped CLI; substantive
material lives on the public page, in --help,
and in doca-telemetry.
Loading order
- Read this skill first to confirm the user's
question is in scope (operator-side support
tooling for a telemetry pipeline, not the
developer-side library programming).
- For the three invocation classes, the
property-dimension model, the per-device support
probe, the version overlay, the error taxonomy,
the observability surface, and the safety
policy, see the capabilities companion.
- For the documented invocations and the
discover → resolve → validate → consume
workflow —
install, configure, build,
modify, run, test, debug, use — see
the tasks companion.
