There is no universally correct number of retention days for prompts, tool arguments, outputs, or traces.
Start with the cost and evidence questions
Agent systems can emit a large amount of telemetry from every model call, tool invocation, retry, queue transition, and error. A single request may produce a trace with dozens of spans, high-frequency metrics, and logs containing content that is both expensive and sensitive. The right control is not “send less of everything.” It is a deliberate separation of data that operators need for immediate decisions from data that is expensive, private, or rarely queried.

OpenTelemetry describes sampling as a way to reduce the number of trace samples collected and sent to a backend. Sampling can lower storage and ingestion, but it also consumes compute, engineering effort, and potentially important evidence. If a system already has low volume, if aggregate metrics answer the operational questions, or if policy requires complete records, sampling may be inappropriate.
Before changing a collector or backend, write down the questions the telemetry must answer:

- [Deep Bass with Clear Vocals] High-performance drivers produce punchy bass while keeping vocals clean and detailed for everyday listening.
- Can an engineer identify a failed agent run and see which model or tool step failed?
- Can the team measure latency, error rate, token or request usage, and queue time by service, model family, tool, and environment?
- Can an incident investigator reconstruct a particular run when the customer, request ID, or deployment is known?
- Which content fields are prohibited, unnecessary, or subject to a contractual or legal retention limit?
- Which evidence must remain available for security, abuse, billing, or reliability investigations?
These questions define the minimum useful telemetry. Cost controls should remove data outside that minimum rather than applying an arbitrary global sampling rate or retention period.
Inventory volume by signal, source, and backend bill
Measure before tuning. Break the workload into logs, metrics, traces, and events, then attribute volume to the agent component that creates it. Model orchestration, retrieval, tool adapters, gateway services, and workers often have very different event rates and payload sizes.
Capture the dimensions that explain spend
- Signal: logs, metric points, spans, profiles, or event records.
- Producer: service, SDK, collector, sidecar, or gateway.
- Payload: event count, serialized bytes, average record size, and attribute count.
- Backend action: ingestion, indexing, storage, query scans, and export.
- Operational value: alerts, dashboards, debugging, compliance, or forensic use.
Use the actual billing units of the selected backend. A system can have modest event counts but high costs when every record carries long prompts, tool arguments, outputs, or verbose exception stacks. Conversely, millions of compact metric points may cost less to ingest than a smaller number of large trace attributes. Include collector CPU, memory, network egress, and the engineering burden of operating stateful processors in the cost model.
Find the dominant cost driver
Compare the measured volume with the provider invoice or self-hosted resource usage. Check whether the bill is driven by ingested bytes, indexed fields, unique series, samples scanned by queries, retention storage, or exports. Do not optimize a metric such as event count when the backend charges on serialized bytes or query scans.
For every proposed reduction, record what evidence disappears, which alert or investigation depends on it, and how the change will be detected if it breaks an operational workflow. This makes a cost reduction reversible rather than a blind data deletion.
Reduce metric cost with temporal and spatial aggregation
The OpenTelemetry Metrics data model identifies two useful transformations. Temporal reaggregation turns high-frequency measurements into longer intervals. Spatial reaggregation combines measurements after removing unwanted attributes. Both can preserve aggregates while reducing points, serialized bytes, and the number of time series.
Temporal reaggregation
Use a longer reporting interval when a second-by-second view does not change an operational decision. For example, an availability dashboard may need a minute-level rate while a capacity report may work at five-minute or hourly resolution. The appropriate interval depends on the alert’s reaction time and the system’s failure modes; it is not a universal setting.

Keep a higher-resolution stream only where it supports a concrete question, such as detecting a short-lived saturation event. If a high-resolution series is retained, define how long it remains queryable and whether a lower-resolution roll-up will replace it afterward.
Spatial reaggregation and bounded dimensions
Every additional attribute can create more series and larger payloads. Useful dimensions for agent operations may include service, model family, outcome class, tool name, and environment. Per-request identifiers, timestamps embedded in labels, raw prompts, tool contents, and generated outputs are poor metric attributes: they create unbounded cardinality, expose content, or make aggregates hard to query.
Choose dimensions from the questions operators actually ask. Keep request or trace identifiers in traces or logs when needed for correlation, not as metric labels. Normalize values into bounded categories such as success, timeout, policy rejection, and upstream error instead of labeling a series with an unrestricted exception message.
AWS’s CloudWatch OpenTelemetry metrics documentation explains that an OTLP point’s serialized ingestion size includes the metric name, labels, resource attributes, timestamp, and value. It recommends shorter label values and dropping high-cardinality labels that are not queried. That pricing behavior is specific to the documented offering and can change, so verify current terms before budgeting.
| Metric design | Resolution and coverage | Cost and risk | When to use |
|---|---|---|---|
| Raw, high-resolution points with many attributes | Fine-grained views and broad slicing | More ingestion bytes, series, storage, and query work; cardinality can grow without bound | Only for questions that genuinely require that detail and for a deliberately limited period |
| Temporally reaggregated points | Longer intervals; short spikes may disappear | Fewer points and lower processing cost | Dashboards and reports whose decisions do not require sub-interval detail |
| Spatially reaggregated points | Fewer bounded dimensions; less per-entity detail | Lower cardinality and payload size; cannot answer removed-dimension queries | Fleet-wide rates, latency distributions, and outcome monitoring |
| Two-tier metrics | High resolution for a short hot window, roll-ups for longer history | More pipeline complexity but controlled long-term storage | Incident response needs detail while trend analysis needs durable aggregates |
Sample traces according to diagnostic value
Trace sampling is a trade-off between volume and evidence. OpenTelemetry notes direct compute costs, indirect engineering costs, and opportunity costs when ineffective sampling misses important information. Measure those costs against the backend savings and the probability that a missing trace would matter.
Head sampling
Head sampling decides before a complete trace is available. A deterministic trace-ID-based decision can keep complete traces at a consistent rate across services. Head sampling is easy to understand, inexpensive to operate, and protects the pipeline early, but it cannot know whether a trace will later contain an error, high latency, or a particular tool result. An important failed run can therefore be discarded before its outcome is visible.
Tail sampling
Tail sampling evaluates all or most spans in a trace before deciding. It can preferentially retain errors, slow traces, selected attributes, or traces from a deployment condition. The collector must hold trace state and have enough memory and compute to wait for the required spans. Operators must monitor queue pressure, late spans, dropped traces, and the effect of sampling rules themselves.

Head and tail together
Very high-volume systems may use a small initial head sample to protect the pipeline, followed by tail decisions on the traces that reach the stateful stage. This can reduce the workload presented to tail sampling, but it also means the initial head decision can still remove evidence that would have met a later priority rule. Document that limitation and test it with synthetic error and latency cases.
| Approach | Decision timing | Can prioritize errors or slow traces? | Operational requirements | Main failure mode |
|---|---|---|---|---|
| Head sampling | At trace start or an early collection stage | No, because the completed trace is not available | Simple deterministic rules; low state and compute | Important traces are discarded before their outcome is known |
| Tail sampling | After most or all spans arrive | Yes, using status, latency, attributes, or deployment context | Stateful components, memory, compute, queueing, and monitoring | State pressure, late spans, or processor failure causes loss or delays |
| Head followed by tail | Early preselection, then completed-trace evaluation | Only for traces that survive the first decision | Both early protection and stateful processing | The initial sample can remove a trace that a tail rule would have kept |
Define trace priorities before choosing a rate
- Keep all traces needed to investigate a defined class of failures, if volume and policy allow.
- Retain slow traces using a latency threshold tied to the service-level objective, not an arbitrary global number.
- Preserve traces for new deployments or changed prompts long enough to detect regressions.
- Keep a representative baseline for successful traffic so error rates and latency distributions remain meaningful.
- Record the sampling decision and configuration version so an investigator knows whether a missing trace was never collected or was later filtered.
Do not claim that a particular sampling percentage is optimal without measuring completeness, alert quality, and incident outcomes for the workload.
Filter, redact, and aggregate before data travels
Processing is most economical when it happens early enough to avoid unnecessary network transfer and downstream work. The OpenTelemetry Kubernetes blueprint recommends processing at different levels when data can be aggregated or filtered early, while central governance provides consistent guardrails for filtering, transformation, redaction, and volume limits.
| Placement | Benefits | Trade-offs | Best use |
|---|---|---|---|
| At the SDK or application | Prevents sensitive or low-value data from leaving the process; minimizes network traffic | Rules may diverge across services; deployment changes are required | Removing known secrets, raw content, debug events, and unneeded attributes at creation |
| Near the workload, such as a node or sidecar collector | Reduces cluster or regional transfer and applies a local standard | More collector instances and configuration distribution | Common redaction, rate limits, and lightweight aggregation close to producers |
| Central collector or gateway | One policy point, easier auditing, and consistent backend routing | Data has already crossed the local network; central capacity becomes critical | Organization-wide rules, tail sampling, routing, and final normalization |
| Backend queries or retention jobs | Rules can change without redeploying producers | Ingestion and indexing costs have already occurred; sensitive data may already be stored | Long-term tiering, deletion, and query-time views rather than primary cost control |
Separate metadata from content
An agent trace can usually correlate model and tool steps, timings, status, and deployment information without retaining full prompts, tool arguments, or outputs indefinitely. Keep content only when a documented operational, security, billing, or contractual purpose requires it. Redaction is not a substitute for classification: identify secrets, personal data, customer material, and regulated fields before deciding whether to hash, tokenize, truncate, encrypt, or drop them.
Use central guardrails without hiding local context
Central rules should enforce maximum rates, prohibited attributes, redaction requirements, and approved destinations. Local teams still need to document why a signal exists and which investigation depends on it. A centrally imposed drop rule that removes the only correlation field can make every downstream trace unusable.

This is a proposal on the project’s main branch, not proof of uniform support. Verify the implementation and version in the target SDK or Collector before relying on that behavior. Decide separately whether a fail-open result should trigger an alert, block a deployment, or route data to a quarantine destination.

Set each duration from operational investigation needs, data sensitivity, contractual and regulatory obligations, query performance, and storage economics.

Classify what must remain queryable
- Operational metadata: identifiers, status, timings, bounded dimensions, and correlations used for reliability work.
- Content-bearing data: prompts, tool arguments, retrieved documents, model outputs, and log fields that may contain sensitive material.
- Aggregates: rates, counts, latency distributions, and usage totals that answer trend and capacity questions without preserving each request.
- Security or audit evidence: records subject to an incident, investigation, contract, or formal control.
For each class, specify the purpose, owner, access roles, deletion trigger, legal hold process, and whether the data is encrypted or further redacted. Have privacy, security, legal, and records-management owners approve the policy for the deployment’s geography and industry; technical telemetry guidance cannot resolve those obligations without that context.
| Retention tier | Typical contents | Access and query behavior | Cost and limitation |
|---|---|---|---|
| Hot operational tier | Recent traces, alerts, bounded metrics, and incident metadata | Fast interactive queries for on-call work; tightly controlled roles | Highest storage and indexing cost; keep only the active investigation window defined by policy |
| Lower-cost searchable tier | Aggregated metrics, selected trace metadata, and sampled evidence | Slower or less flexible queries for trend analysis and post-incident review | Lower storage price but reduced detail and potentially different query limits |
| Unsampled or restricted archive | Complete records only where an approved purpose requires them | Limited access, controlled retrieval, and documented audit trail | More storage, access-control, and legal exposure; may be prohibited for some content |
| Deleted or non-retained content | Unneeded prompts, outputs, secrets, and debug payloads | Not queryable after processing | Lowest cost and exposure, but cannot support later content reconstruction |
Make deletion and legal holds explicit
Automated expiry should remove data at the end of its approved period, while a documented legal or security hold can suspend deletion for a defined case. Log deletion outcomes and exceptions. If a backend cannot enforce per-signal or per-tenant expiry, route the data to a store that can or avoid sending the sensitive signal there.

Pricing models differ, so a control that saves money in one backend may have little effect in another. Compare actual ingestion units, included retention, query charges, indexing and cardinality rules, collector compute, staffing, and exportability for the backend you operate.
AWS documents a CloudWatch OpenTelemetry metrics model that charges per gigabyte of ingested data, includes 15 months of storage, provides free console PromQL queries, and charges programmatic PromQL queries per million samples scanned. The documentation says the model bills on ingested data volume rather than unique series count; high-cardinality labels still increase serialized bytes. The page does not state a numeric rate for samples scanned, and its terms apply only to that AWS offering. Re-check the current documentation and your region’s pricing before using those figures in a budget.
For a self-hosted backend, include the cost of collector replicas, stateful tail-sampling buffers, storage hardware or object storage, index maintenance, backups, upgrades, on-call staffing, and egress. A lower vendor invoice is not a saving if the pipeline requires substantially more engineering or loses the ability to export evidence.
A staged implementation workflow
- Inventory. Measure events, bytes, attributes, series, spans, query scans, and storage by signal and producer. Capture the corresponding backend charges and collector resource use.
- Define required questions. List alerts, dashboards, incident investigations, security cases, billing checks, and audit obligations. Mark which require content, which require metadata, and which require only aggregates.
- Remove unnecessary or sensitive data at creation. Drop debug events that have no approved use. Redact or tokenize secrets and personal data. Avoid placing raw content or per-request identifiers in metric labels.
- Bound metric dimensions. Keep only attributes that support a named operational question. Replace unrestricted values with bounded categories and shorten serialized labels where the backend charges by bytes.
- Aggregate metrics. Apply temporal or spatial reaggregation at the earliest practical stage. Preserve a higher-resolution stream only when an alert or investigation needs it, and define its expiry.
- Choose trace sampling rules. Decide whether head, tail, or a combined design can retain errors, slow traces, deployment changes, and a representative success baseline. Account for state, memory, compute, and late spans.
- Place processing early. Filter and redact in the SDK or near the workload when the rule is known there. Use central collectors for shared governance, routing, and final policy enforcement.
- Assign retention tiers. Separate hot operational data, lower-cost aggregates or metadata, restricted complete records, and data that should never be retained. Document owners, access, expiry, and holds.
- Test failure and recovery. Generate known successes, errors, slow traces, retries, and policy failures. Confirm that alerts still fire, correlations still work, and a collector outage does not silently violate the data policy.
- Roll out in stages. Start with one service or environment, compare cost and evidence before and after, then expand. Keep configuration versions and a rollback path for every change.
Validate that savings did not destroy observability
Review the system after each change with the same questions used to define the minimum dataset. Check alert precision and latency, trace completeness for selected test cases, metric resolution, query performance, and the ability to correlate a model call with its tool steps. Track dropped-event counters, sampling decisions, queue saturation, policy-evaluation failures, and redaction failures as telemetry about the telemetry pipeline.
Free tools Windows power users keep installed
One-click scans. No signup required.
Run a controlled incident exercise. Start with a failed tool call, a high-latency model response, and a deployment that changes agent behavior. An investigator should be able to find the relevant metadata, identify the missing content by policy, and determine whether sampling or expiry explains any gap. If the exercise fails, restore the previous configuration, narrow the rule, or retain a temporary diagnostic stream with an explicit expiry rather than permanently increasing all telemetry.
Common mistakes and safer corrections
Applying one global sampling percentage
A single rate treats routine successes and rare failures as equally valuable. Define priority conditions first, then measure whether the chosen head or tail policy preserves them.
Keeping every prompt and output “just in case”
Indefinite content retention increases storage, access, and privacy exposure without guaranteeing that the data will be useful. Keep metadata and aggregates by default; retain content only for an approved purpose with a defined expiry.
Filtering only after ingestion
Backend deletion does not recover network, collector, ingestion, or indexing cost, and sensitive data may already have been stored. Move known drops and redaction as close to production as practical while retaining central guardrails.
Recommended Free Tools
Using request IDs as metric labels
Unbounded labels create high cardinality and make aggregate queries expensive. Keep identifiers in traces or logs for correlation, and use bounded dimensions for metrics.
Assuming a policy proposal is universally implemented
Telemetry-policy capabilities and fail-open behavior must be verified for the exact SDK and Collector versions in use. Treat unsupported rules as configuration failures that require an operational response, not as silently enforced controls.
Optimizing ingestion while ignoring query cost
Aggregation and sampling can reduce stored data while a dashboard still scans excessive samples or broad time ranges. Measure query scans and latency, then design dashboards around bounded dimensions and appropriate roll-ups.
Bottom line
The durable strategy is selective collection, not indiscriminate deletion. Inventory the real cost, remove unnecessary content and attributes at the source, aggregate metrics to the resolution operators need, and use head or tail sampling according to the evidence each trace can provide. Then assign retention by signal, sensitivity, and purpose, with explicit access, expiry, and legal-hold rules. Revalidate alerts and investigations after every change; a telemetry bill is only “controlled” when the remaining data still supports the decisions your team must make.
