Overview

Diagnose why a SigNoz alert fired by correlating the alert's own signal with neighbor signals (error rate, latency, throughput, CPU/memory), traces, and logs around the fire window — and rank likely causes. Make sure to use this skill whenever the user asks "why did this alert fire", "what caused alert X", "investigate this alert", "RCA for the alert that paged me", "what's wrong with [service]" in the context of a recent fire, or otherwise asks for a root-cause analysis of a firing or recently-fired alert. Read-only — does not modify any alert or notification.

Alert Investigate

Diagnose why a SigNoz alert fired. The skill correlates the alert's own signal with neighbor signals around the fire window, and surfaces a ranked list of likely causes with supporting evidence. It is the companion to signoz-explaining-alerts: explain decodes the rule statically; investigate diagnoses a specific incident.

Prerequisites

This skill calls SigNoz MCP server tools heavily (signoz_get_alert, signoz_get_alert_history, signoz_execute_builder_query, signoz_query_metrics, signoz_search_traces, signoz_search_logs, signoz_get_trace_details, etc.). Before running the workflow, confirm the signoz_* tools are available. If they are not, the SigNoz MCP server is not installed or configured; run signoz-mcp-setup first to initialize or repair the MCP connection. The investigation depends on correlating multiple MCP queries; without the server there is no way to ground the analysis.

When to use

Use this skill when the user wants to:

Understand why a specific alert fired.
Find the root cause of a recent incident triggered by an alert.
Correlate the alert's signal with related metrics, traces, and logs.
Distinguish "real signal" fires from flapping or threshold-mistuning.

Do NOT use when the user wants to:

Understand what an alert is configured to monitor → signoz-explaining-alerts.
Create a new alert → signoz-creating-alerts.
Modify an alert (raise threshold, add hysteresis) → call signoz_update_alert directly.
Run a free-form ad-hoc investigation without an alert as the anchor → signoz-generating-queries.

Required inputs

Input	Required	Source if missing
Alert identifier (rule ID or name)	yes	`$ARGUMENTS[0]` or recent context
Time window	no	default to most recent fire from `signoz_get_alert_history`

If the alert name is fuzzy, this skill is best-effort (read-only):

Call signoz_list_alert_rules, paginate, fuzzy-match the name.
State the interpretation: "Investigating fire of 'High Error Rate - Checkout' (id 42) at 14:32 UTC. If you meant a different alert or fire, tell me."
Proceed.

If no firing transition exists in the queried lookback window, stop: there is nothing to investigate. Respond with:

"Alert '[name]' has not fired in the last 7d, so there is no fire window to investigate. Use signoz-explaining-alerts to walk through the rule, or check whether the alert is enabled."

Workflow

The investigation runs in three tiers with strict early-stop gates. Tier 1 always runs. Tier 2 runs only if tier 1 confirms a real fire. Tier 3 runs only if tier 2 surfaces correlated anomalies. Skipping the gates produces hundreds of unnecessary trace/log queries on quiet alerts.

Step 1: Resolve alert + fire window (Tier 0)

Resolve the alert id via signoz_list_alert_rules (paginated) if not given.
Call signoz_get_alert for the full rule config, needed to know what query, threshold, and resource scope the alert evaluated.
First call signoz_get_alert_history with timeRange: "7d" and order: "desc"; omit state so the timeline includes firing and inactive transitions. Continue only when data.nextCursor exists (the completeness note also reports hasMore: true). Pass it as cursor, replace timeRange with the note's resolved absolute start and end, and preserve the same state/filter (including omission) and order. Stop when nextCursor is absent / the note reports hasMore: false; never use offset or page fullness. If a later intentional state filter means "resolved" / "recovered", use inactive. The enum is inactive|pending|recovering|firing|nodata|disabled; recovering is a transient keep-firing state, not resolution. Pattern analysis needs the complete transition set. Rows are emitted per label-group fingerprint; do not interleave them. From the response:
- Build rule-wide incident windows from distinct rows where overallStateChanged: true: an overallState: "firing" transition opens an incident; the next overallState: "inactive" closes it. Deduplicate matching timestamps and sort by unixMilli ascending before pairing. Default to the most recent incident unless $ARGUMENTS[1] selects another.
- Partition affected series by fingerprint and retain each row's labels. Use only stateChanged: true rows to decide when that group fired and resolved, and which group should scope Tier 1–3 queries.
- Note the fire pattern from rule-wide transitions or one named fingerprint:
  - one-off → single fire with a long quiet period before/after.
  - sustained → fires that stayed firing for ≥ 1 evaluation cycle.
  - flapping → ≥ 3 fires within a 1h window, alternating fire/resolve.
  - recurring → fires at regular intervals (cron-like, e.g., every hour).
- Never infer flapping from different fingerprints. The pattern guides tiers 2/3.

Step 2: Tier 1 (what fired and how hard)

This tier always runs. It establishes the fire is real (vs. transient threshold tickle or flap) and quantifies the magnitude.

Re-run the alert's primary query over a window centered on the fire start: [fire_start - 30m, fire_start + 30m].
- Use signoz_execute_builder_query for the alert's stored builder, formula, PromQL, or ClickHouse query envelope.
- Preserve positive bounds/order so Tier 1 reproduces the stored alert. If a formula input is below 10000, record truncation risk and compare at 10000 before ruling groups out. For omissions, use 10000 on formula-input builder_query leaves and 100 on standalone/formula results. Find leaves from every formula expression, including disabled: true formulas, following references through the dependency graph. This walk sets comparison bounds only; it does not prove deterministic formula-to-formula order. Use v5 order: __result desc for metrics/formulas or primary aggregation desc for logs/traces, never dashboard orderBy. Time-series top-N ranks over the whole window and may omit a short-lived local spike.
Compute:
- Peak value during the fire window.
- Threshold breach magnitude: (peak - threshold) / threshold * 100 for "above" alerts, inverted for "below".
- Fire duration: the rule's overall firing→inactive interval, or the selected fingerprint's interval for a group-scoped investigation. Say which.
- Pre-fire baseline: average value in the 30m before fire start.
Early-stop gate: if the breach magnitude is < 10% over the threshold AND the fire duration is < 1 evaluation window, classify as "marginal fire"; the alert may be too sensitive. Skip tiers 2 and 3 and go to Step 5 with a single hypothesis: "threshold may be too tight, recommend tuning."

Step 3: Tier 2 (neighbor signals vs baseline)

Run only if Tier 1 confirms a real breach. Pull related signals for the same resource scope as the alert and compare the fire window to a baseline window.

Pick a baseline window. Use the same hour, previous day (fire_start - 24h, fire_start - 24h + fire_duration). If the alert fired during a known-anomalous time (deploy, weekly job), note it in the output but still proceed.
Look up neighbor signals for the alert's resource type. See references/neighbor-signals.md for the lookup table. Common cases:
- Service-level alert (service.name = X): pull error rate, p95/p99 latency, request throughput, dependency error rates if trace data is available.
- Host / VM alert (host.name = X): CPU, memory, disk I/O, network I/O.
- K8s pod / namespace alert: pod restarts, container CPU/memory limits, node pressure, recent rollouts.
For each neighbor signal:
- Query both windows (fire + baseline) via signoz_execute_builder_query or signoz_query_metrics.
- Compute the delta (% change in fire window vs baseline).
- Rank by absolute delta.
Early-stop gate: if no neighbor signal shows ≥ 25% deviation from baseline, classify as "isolated fire: the alert's own signal moved but nothing else did." This is unusual and worth surfacing. Skip Tier 3 and go to Step 5 with hypotheses focused on the alert's own query (likely causes: data source change, instrumentation change, downstream silent failure that only shows in this metric).

Step 4: Tier 3 (traces and logs at the fire window)

Run only if Tier 2 found correlated neighbor anomalies. Drill into specific failing operations.

Traces (if the alert is service-scoped and traces are available):
- Call signoz_search_traces for the fire window with filter: service.name = <scope> AND has_error = true. Cap at top 20.
- Group by name and status_message. Surface the sample's top 3 with one trace ID each; do not call a 20-row sample count full-window frequency.
- Optionally call signoz_get_trace_details for span attributes. Pass the search row's trace_id as traceId plus the same absolute fire-window start and end; otherwise the 6h default misses older incidents.
Logs for the fire window:
- Call signoz_search_logs with filter: <scope_filter> AND severity_text IN ('ERROR', 'FATAL'). Cap at top 20 most recent.
- Group by body pattern (or exception.type if present). Surface the top 3 distinct messages with counts.
Cross-reference: do the traces and logs point at the same downstream service, dependency, or code path? If so, that becomes the leading hypothesis.

See references/baseline-comparison.md for query templates that pair fire-window and baseline-window calls cleanly.

Step 5: Build the structured output

Use this exact section order. Lead with a TL;DR, because engineers under pressure scan the top first and stop reading once they have what they need. Every claim cites the MCP query that produced it, with no generic "check logs / verify connectivity" filler.

1. TL;DR: one or two sentences, no more. Leading hypothesis, overall confidence, blast radius, and the single most useful next action. Example:

"checkoutservice error rate hit 12.4% (threshold 5%) for 8m at 14:32 UTC; most likely cause is payments-api timing out (high confidence). Open trace 7af3a09b… to see the failing call."

If no hypothesis reaches medium confidence, the leading line is "No clear root cause found." rather than a low-confidence guess dressed up as the answer.

2. What fired The alert (id, name), the fire window (absolute UTC + relative), peak magnitude ("error rate hit 12.4% vs. 5% threshold, 148% over"), fire duration, and the fire pattern (one-off / sustained / flapping / recurring / marginal).

3. Investigation trail A scannable list of what was checked, with ✅ for confirmed signals and ❌ for ruled out, each followed by a one-line finding. The point is that the reader can see what work the AI did and what it found. Example:

✅ Tier 1: peak error rate 12.4%, fire was real (not marginal).
✅ Tier 2: payments error rate +8900%, p99 +1180%; downstream cascade.
❌ CPU / memory pressure: flat through the fire window.
✅ Tier 3:

# Alert Investigate

Diagnose why a SigNoz alert fired. The skill correlates the alert's own
signal with neighbor signals around the fire window, and surfaces a
ranked list of likely causes with supporting evidence. It is the
companion to `signoz-explaining-alerts`: explain decodes the rule
statically; investigate diagnoses a specific incident.

## Prerequisites

This skill calls SigNoz MCP server tools heavily (`signoz_get_alert`,
`signoz_get_alert_history`, `signoz_execute_builder_query`,
`signoz_query_metrics`, `signoz_search_traces`, `signoz_search_logs`,
`signoz_get_trace_details`, etc.). Before running the workflow,
confirm the `signoz_*` tools are available. If they are not, the
SigNoz MCP server is not installed or configured; run `signoz-mcp-setup` first
to initialize or repair the MCP connection. The investigation depends on
correlating multiple MCP queries; without the server there is no way to ground
the analysis.

## When to use

Use this skill when the user wants to:
- Understand why a specific alert fired.
- Find the root cause of a recent incident triggered by an alert.
- Correlate the alert's signal with related metrics, traces, and logs.
- Distinguish "real signal" fires from flapping or threshold-mistuning.

Do NOT use when the user wants to:
- Understand what an alert is configured to monitor → `signoz-explaining-alerts`.
- Create a new alert → `signoz-creating-alerts`.
- Modify an alert (raise threshold, add hysteresis) → call
`signoz_update_alert` directly.
- Run a free-form ad-hoc investigation without an alert as the anchor →
`signoz-generating-queries`.

## Required inputs

| Input | Required | Source if missing |
|---|---|---|
| Alert identifier (rule ID or name) | yes | `$ARGUMENTS[0]` or recent context |
| Time window | no | default to most recent fire from `signoz_get_alert_history` |

If the alert name is fuzzy, this skill is **best-effort** (read-only):
1. Call `signoz_list_alert_rules`, paginate, fuzzy-match the name.
2. State the interpretation: "Investigating fire of 'High Error Rate -
Checkout' (id 42) at 14:32 UTC. If you meant a different alert or
fire, tell me."
3. Proceed.

If no firing transition exists in the queried lookback window, **stop**: there is
nothing to investigate. Respond with:
> "Alert '[name]' has not fired in the last 7d, so there is no fire
> window to investigate. Use `signoz-explaining-alerts` to walk through
> the rule, or check whether the alert is enabled."

## Workflow

The investigation runs in three tiers with strict early-stop gates.
Tier 1 always runs. Tier 2 runs only if tier 1 confirms a real fire.
Tier 3 runs only if tier 2 surfaces correlated anomalies. Skipping the
gates produces hundreds of unnecessary trace/log queries on quiet
alerts.

### Step 1: Resolve alert + fire window (Tier 0)

1. Resolve the alert id via `signoz_list_alert_rules` (paginated) if
not given.
2. Call `signoz_get_alert` for the full rule config, needed to know
what query, threshold, and resource scope the alert evaluated.
3. First call `signoz_get_alert_history` with `timeRange: "7d"` and
`order: "desc"`; omit `state` so the timeline includes firing and inactive
transitions. Continue only when `data.nextCursor` exists (the completeness
note also reports `hasMore: true`). Pass it as `cursor`, replace `timeRange`
with the note's resolved absolute `start` and `end`, and preserve the same
state/filter (including omission) and order. Stop when `nextCursor` is absent
/ the note reports `hasMore: false`; never use `offset` or page fullness.
If a later intentional state filter means "resolved" / "recovered", use
`inactive`. The enum is `inactive|pending|recovering|firing|nodata|disabled`;
`recovering` is a transient keep-firing state, not resolution.
Pattern analysis needs the complete transition set. Rows are emitted per
label-group `fingerprint`; do not interleave them. From the response:
- **Build rule-wide incident windows** from distinct rows where
`overallStateChanged: true`: an `overallState: "firing"` transition opens
an incident; the next `overallState: "inactive"` closes it. Deduplicate
matching timestamps and sort by `unixMilli` ascending before pairing.
Default to the most recent incident unless `$ARGUMENTS[1]` selects another.
- **Partition affected series by `fingerprint`** and retain each row's
labels. Use only `stateChanged: true` rows to decide when that group fired
and resolved, and which group should scope Tier 1–3 queries.
- **Note the fire pattern** from rule-wide transitions or one named fingerprint:
- `one-off` → single fire with a long quiet period before/after.
- `sustained` → fires that stayed firing for ≥ 1 evaluation cycle.
- `flapping` → ≥ 3 fires within a 1h window, alternating fire/resolve.
- `recurring` → fires at regular intervals (cron-like, e.g., every hour).
- Never infer flapping from different fingerprints. The pattern guides tiers 2/3.

### Step 2: Tier 1 (what fired and how hard)

This tier always runs. It establishes the fire is real (vs. transient
threshold tickle or flap) and quantifies the magnitude.

1. Re-run the alert's primary query over a window centered on the fire
start: `[fire_start - 30m, fire_start + 30m]`.
- Use `signoz_execute_builder_query` for the alert's stored builder,
formula, PromQL, or ClickHouse query envelope.
- Preserve positive bounds/order so Tier 1 reproduces the stored alert. If a formula input is below 10000, record truncation risk and compare at 10000 before ruling groups out.
For omissions, use 10000 on formula-input `builder_query` leaves and 100 on standalone/formula results. Find leaves from every formula expression, including `disabled: true` formulas, following references through the dependency graph.
This walk sets comparison bounds only; it does not prove deterministic formula-to-formula order. Use v5 `order`: `__result desc` for metrics/formulas or primary aggregation desc for logs/traces, never dashboard `orderBy`.
Time-series top-N ranks over the whole window and may omit a short-lived local spike.
2. Compute:
- **Peak value** during the fire window.
- **Threshold breach magnitude**: `(peak - threshold) / threshold *
100` for "above" alerts, inverted for "below".
- **Fire duration**: the rule's overall firing→inactive interval, or the
selected fingerprint's interval for a group-scoped investigation. Say which.
- **Pre-fire baseline**: average value in the 30m before fire start.
3. **Early-stop gate**: if the breach magnitude is < 10% over the
threshold AND the fire duration is < 1 evaluation window, classify
as "marginal fire"; the alert may be too sensitive. Skip tiers 2
and 3 and go to Step 5 with a single hypothesis: "threshold may be
too tight, recommend tuning."

### Step 3: Tier 2 (neighbor signals vs baseline)

Run only if Tier 1 confirms a real breach. Pull related signals for the
same resource scope as the alert and compare the fire window to a
baseline window.

1. **Pick a baseline window**. Use the same hour, previous day
(`fire_start - 24h, fire_start - 24h + fire_duration`). If the
alert fired during a known-anomalous time (deploy, weekly job),
note it in the output but still proceed.

2. **Look up neighbor signals** for the alert's resource type. See
`references/neighbor-signals.md` for the lookup table. Common cases:
- **Service-level alert** (`service.name = X`): pull error rate,
p95/p99 latency, request throughput, dependency error rates if
trace data is available.
- **Host / VM alert** (`host.name = X`): CPU, memory, disk I/O,
network I/O.
- **K8s pod / namespace alert**: pod restarts, container CPU/memory
limits, node pressure, recent rollouts.

3. For each neighbor signal:
- Query both windows (fire + baseline) via
`signoz_execute_builder_query` or `signoz_query_metrics`.
- Compute the delta (% change in fire window vs baseline).
- Rank by absolute delta.

4. **Early-stop gate**: if no neighbor signal shows ≥ 25% deviation
from baseline, classify as "isolated fire: the alert's own signal
moved but nothing else did." This is unusual and worth surfacing.
Skip Tier 3 and go to Step 5 with hypotheses focused on the alert's
own query (likely causes: data source change, instrumentation
change, downstream silent failure that only shows in this metric).

### Step 4: Tier 3 (traces and logs at the fire window)

Run only if Tier 2 found correlated neighbor anomalies. Drill into
specific failing operations.

1. **Traces** (if the alert is service-scoped and traces are
available):
- Call `signoz_search_traces` for the fire window with filter:
`service.name = <scope>` AND `has_error = true`. Cap at top 20.
- Group by `name` and `status_message`. Surface the sample's top 3 with one
trace ID each; do not call a 20-row sample count full-window frequency.
- Optionally call `signoz_get_trace_details` for span attributes. Pass the
search row's `trace_id` as `traceId` **plus the same absolute fire-window
`start` and `end`**; otherwise the 6h default misses older incidents.

2. **Logs** for the fire window:
- Call `signoz_search_logs` with filter:
`<scope_filter>` AND `severity_text IN ('ERROR', 'FATAL')`. Cap
at top 20 most recent.
- Group by `body` pattern (or `exception.type` if present). Surface
the top 3 distinct messages with counts.

3. Cross-reference: do the traces and logs point at the same
downstream service, dependency, or code path? If so, that becomes
the leading hypothesis.

See `references/baseline-comparison.md` for query templates that pair
fire-window and baseline-window calls cleanly.

### Step 5: Build the structured output

Use this exact section order. Lead with a TL;DR, because engineers
under pressure scan the top first and stop reading once they have what
they need. Every claim cites the MCP query that produced it, with no
generic "check logs / verify connectivity" filler.

**1. TL;DR**: one or two sentences, no more. Leading hypothesis,
overall confidence, blast radius, and the single most useful next
action. Example:
> "checkoutservice error rate hit 12.4% (threshold 5%) for 8m at
> 14:32 UTC; most likely cause is payments-api timing out
> (high confidence). Open trace `7af3a09b…` to see the failing call."

If no hypothesis reaches medium confidence, the leading line is
"No clear root cause found." rather than a low-confidence guess
dressed up as the answer.

**2. What fired**
The alert (id, name), the fire window (absolute UTC + relative),
peak magnitude ("error rate hit 12.4% vs. 5% threshold, 148% over"),
fire duration, and the fire pattern (`one-off` / `sustained` /
`flapping` / `recurring` / `marginal`).

**3. Investigation trail**
A scannable list of what was checked, with ✅ for confirmed signals
and ❌ for ruled out, each followed by a one-line finding. The point
is that the reader can see what work the AI did and what it found.
Example:
- ✅ Tier 1: peak error rate 12.4%, fire was real (not marginal).
- ✅ Tier 2: payments error rate +8900%, p99 +1180%; downstream
cascade.
- ❌ CPU / memory pressure: flat through the fire window.
- ✅ Tier 3:
