JEP-0013 - Phase 3 - client PushLogs - #1064
Conversation
Add the MetricsStream protocol and Go hub so Prometheus can scrape merged exporter OpenMetrics from telemetry without an exporter client yet. Generated Python stubs are included for proto consistency. Co-authored-by: Cursor <cursoragent@cursor.com>
Stop silently dropping unparseable exporter snapshots. Log the exporter and error, and increment jumpstarter_metrics_parse_errors_total so reverse-scrape omissions are visible on the same /metrics response. Co-authored-by: Cursor <cursoragent@cursor.com>
…e 3) Build /telemetry into the controller image and have the operator mount cert-manager TLS, advertise the CA, and expose scrape flags plus the HTTP metrics port so reverse-scrape can run in-cluster.
Forward PushLogs to Loki through a bounded ring buffer so a slow sink
cannot stall exporters; overflow becomes one drop-marker LogEntry and
jumpstarter_telemetry_dropped_total{destination="loki"}.

🌐 Web query:
Does prometheus/common expfmt OpenMetrics decoder support exemplar suffixes on sample lines?
💡 Result:
The prometheus/common expfmt package's OpenMetrics decoder does not fully support the OpenMetrics specification [1]. The official documentation explicitly states that the decoder in this package is not intended for high-performance applications, does not fully support OpenMetrics, and may fall back to classic Prometheus text decoding [1]. Regarding OpenMetrics exemplars, while the expfmt package provides functionality to generate (encode) OpenMetrics output that includes exemplars [2][3][4], the decoding support is limited. The current decoder logic in expfmt typically relies on classic text parsing, which does not natively handle the specialized OpenMetrics exemplar syntax (which follows the sample line, starting with a hash # symbol) [1][5][4]. Consequently, it does not support exemplar suffixes on sample lines as defined by the OpenMetrics specification [1][6][5].

github prometheus common v0.62.0 expfmt decode.go OpenMetrics exemplar suffix NewDecoder TypeOpenMetrics text fallback
💡 Result:
In the prometheus/common v0.62.0 library, the expfmt package's decode.go file contains a NewDecoder function that acts as a factory for decoders [1]. This decoder is explicitly documented to have limited support for OpenMetrics [1]. While it may often successfully decode OpenMetrics data due to similarities between the formats, it is not a full-featured OpenMetrics implementation and relies on a fallback mechanism to classic Prometheus text decoding [1]. Regarding the handling of exemplars and suffixes, the expfmt package manages OpenMetrics exemplars and metric name suffixes (such as _total for counters) primarily through its encoder logic in openmetrics_create.go rather than the primary NewDecoder [2][3]. The writeOpenMetricsSample function in openmetrics_create.go handles the writing of metric names with their suffixes (e.g., name+suffix) and appends exemplars if they are present [2]. The NewDecoder function itself delegates decoding to a textDecoder, which uses a TextParser to process metric families [1]. As noted in the source documentation, this decoder is intended for standard Prometheus text format and does not fully support the OpenMetrics specification, which is why it utilizes a fallback approach [1]. Users requiring full OpenMetrics support are advised that the library's expfmt components are considered internal and lack stability guarantees for external usage [4][5].

Do not drop exporter snapshots that contain OpenMetrics exemplars
parseMetricFamilies uses github.com/prometheus/common/expfmt v0.62.0 with TypeOpenMetrics, but its decoder falls back to the text parser, which rejects exemplar suffixes. mergeSnapshots then skips the entire snapshot and records jumpstarter_metrics_parse_errors_total, so /metrics omits the exporter histogram and other families. If this limitation is not intentional, strip the suffix or use a decoder with exemplar support. Otherwise, document the limitation and follow-up at parseMetricFamilies.

Bound telemetry flushing during shell shutdown.
TelemetryLogHandler.close_async() drains the complete queue. Each unavailable PushLogs batch can wait for its 10-second timeout. A telemetry outage with queued logs can delay jmp shell exit once per batch. Add a finite shutdown budget, then drop remaining telemetry entries and close the handler.

minimal, and validate.
In `@python/packages/jumpstarter/jumpstarter/client/telemetry.py` at line 55,
Update the telemetry channel and PushLogs metadata flow around
grpc.aio.insecure_channel so config.token is never sent when TLS is inactive;
skip telemetry or omit the token in insecure mode without an endpoint
certificate, while preserving token transmission only for TLS-secured channels.

Summary
JEP-0013 Phase 3 PR E**:
jmpcan discover telemetry and push structured logs withcomponent=cli, without changing human-facing stdout.Depends on PR A: #1060
Depends on PR B: #1061
Depends on PR D: #1063
Independent of PR C (#1062) — MetricsStream spoke. Do not merge until A, B, and D are on
main, then rebase.GetServiceEndpointsaccepts a client token as well as an exporter token.PushLogsaccepts client tokens (authenticatePushLogs); identity overwrite usesclientfor client tokens andexporterfor exporter tokens.jumpstarter.client.telemetry.attach_client_telemetryreuses the exporterTelemetryLogHandlerwithcomponent=cli.jmp shell. Missing/unconfigured telemetry is a best-effort skip. Flush loop starts next to the shell task group; handler is closed on the way out.Lab:
jmp shell --client p16v --name sidekick-t450sis the client path this PR enables. Human-facing pane output is unchanged. Exporter TFTP errors and MetricsStream identity/parse_errorsare not this PR.DEMO
The lab walkthrough for the stacked Phase 3 work (A+B+C+D+E plus lab-only Route) is on the fork demo branch, not this PR:
Pane 0 in that recording is
jmp shell(this PR). PushLogs remains the operation ledger while reverse-scrape omits exemplar-bearing snapshots (A / DD-3).How this PR fits the series
