agent couldn't parse timestamp format in metric feed error failed da

Not specified by the original author.

TL;DR

Fix this in the anomaly detector by acting on the exact message first: inspect the raw file or payload at the failure point, fix encoding, quoting or header duplication there, and parse with a tolerant reader that logs skipped rows. Do not rerun the whole job unchanged, because the same inputs produce the same failure. Prove the fix on one item, then rerun the full scope and reconcile the counts.

agent couldn't parse timestamp format in metric feed error failed date parsing

Use this when

• The operation in the anomaly detector fails with this exact message: agent couldn't parse timestamp format in metric feed error failed date parsing.
• The same failure repeats on retry with unchanged inputs.
• A review, export or check is blocked until this item completes.

Not for this skill when

• The message is a permission or outage notice from the platform. Resolve that first, then return here if this error remains.
• The operation completes and you only disagree with its output. That is a quality review, not this failure.

Steps

1. Reproduce the failure with the smallest scope that still shows it in the anomaly detector, and copy the full message plus the item, user or metric involved into the run notes. Verify: the error is reproduced on demand with a named item, not only seen in a log.
2. Apply the specific fix for this error: inspect the raw file or payload at the failure point, fix encoding, quoting or header duplication there, and parse with a tolerant reader that logs skipped rows. Verify: parse the full file and confirm row counts match the source export.
3. Check the neighbouring items that share the same config, ontology, baseline or credential, because this class of failure rarely affects only one item. Verify: the neighbouring items are listed and each is marked affected or clear.
4. Rerun the original operation in the anomaly detector on the previously failing scope, watching for the same message rather than assuming success from a quiet log. Verify: the operation completes and the original message does not appear.
5. Compare the result counts, decisions or alerts against the source in the anomaly detector so a silent partial success is caught before sign off. Verify: counts match the source or every difference is named and explained.
6. Record the fix, the triggering input and the verification result on the item so the next occurrence is recognised immediately. Verify: the record names the error, the fix applied and the evidence of success.

Why it happens

Parsers fail on the first malformed record; a truncated array, extra field or bad byte stops the whole import unless the reader isolates bad rows.

TL;DR

Fix this in syslog ingestion by acting on the exact message first: identify the timestamp format the source actually sends (including timezone and whether the year is present), set the ingestion parser to that exact format, and replay the dropped syslog lines. Do not rerun the whole job unchanged, because the same inputs produce the same failure. Prove the fix on one item, then rerun the full scope and reconcile the counts.

timestamp parsing failed

Use this when

• The operation in syslog ingestion fails with this exact message: timestamp parsing failed.
• The same failure repeats on retry with unchanged inputs.
• A review, export or check is blocked until this item completes.

Not for this skill when

• The message is a permission or outage notice from the platform. Resolve that first, then return here if this error remains.
• The operation completes and you only disagree with its output. That is a quality review, not this failure.

Steps

1. Reproduce the failure with the smallest scope that still shows it in syslog ingestion, and copy the full message plus the alert, incident or enrichment record involved into the run notes. Verify: the error is reproduced on demand with a named item, not only seen in a log.
2. Apply the specific fix for this error: identify the timestamp format the source actually sends (including timezone and whether the year is present), set the ingestion parser to that exact format, and replay the dropped syslog lines. Verify: replayed events land in the index with correct event times and no parsing failures.
3. Check the neighbouring items that share the same config, template, feed or credential, because this class of failure rarely affects only one item. Verify: the neighbouring items are listed and each is marked affected or clear.
4. Compare the result counts, decisions or alerts against the source in syslog ingestion so a silent partial success is caught before sign off. Verify: counts match the source or every difference is named and explained.
5. Rerun the original operation in syslog ingestion on the previously failing scope, watching for the same message rather than assuming success from a quiet log. Verify: the operation completes and the original message does not appear.
6. Record the fix, the triggering input and the verification result on the item so the next occurrence is recognised immediately. Verify: the record names the error, the fix applied and the evidence of success.

Why it happens

the source sends a syslog variant the parser does not expect, so the timestamp fails to parse and the events are dropped instead of indexed with a receive time.

TL;DR

Dagster event timestamps come in multiple representations: epoch floats in some API responses, ISO strings in others, and timezone handling that varies by client. Normalize everything to UTC epoch at the ingestion boundary and parse defensively. A parser that assumes one format breaks on the first event that uses the other.

agent can't parse dagster event log timestamps, parsing failed

Use this when

• An agent's parser fails on Dagster event timestamps.
• Some events parse and others do not.
• Timezone-naive and timezone-aware values mix.

Not for this skill when

• Events are missing entirely. That is a query problem.
• The timestamps parse but look wrong. That is a timezone bug.

Steps

1. Capture a failing timestamp value verbatim. Note the exact string or number. Verify: the failing format is in hand
2. Enumerate the formats Dagster emits in your path: epoch float, ISO string, with and without timezone. Note the set. Verify: the format zoo is mapped
3. Write a parser that tries each format and normalizes to UTC epoch. Note the function. Verify: one parser handles all formats
4. Add the failing samples as regression tests. Note the tests. Verify: the formats are pinned
5. Verify the parser handles a mixed event stream. Note the clean parse. Verify: the fix is verified

Variant phrasings

dagster event timestamp format

The format-shaped search.

dagster graphql timestamp parsing

The API-shaped phrasing.

Compatibility: Dagster 1.x event logs via GraphQL and Python APIs. Formats are stable but mixed across endpoints.

Why it happens

Dagster's event system grew organically: storage writes epoch floats, GraphQL serializes ISO strings, and clients add their own timezone assumptions. No single format won, so consumers see several. A parser written against one endpoint's format breaks the moment the agent queries a different endpoint or Dagster changes a serializer. Normalizing at the boundary, one function, every timestamp in, UTC epoch out, contains the mess in a single place.

Edge cases / pitfalls

• Epoch floats lose precision for very old or far-future dates in float32 contexts. Use float64 or decimal.
• Timezone-naive ISO strings are ambiguous. Assume UTC only if you have verified the emitter; otherwise treat as an error.
• Sorting events by timestamp across formats without normalizing first produces wrong orders. Normalize before comparing.
• Dagster version upgrades can change a serializer. Re-run the format regression tests after upgrades.
