2. Purpose
SLAMonitor tracks service-level objectives committed to internally and to users, measures error-budget burn rate, and emits alerts when burn rate approaches the SLO budget limit. Retained 7 years as a compliance-grade availability record.
3. Why This Bot Matters
No SLO tracking
Availability and latency regressions go undetected until users complain; SLA breach evidence is unavailable for compliance.
Error budget burn not tracked
The team consumes the entire error budget without realising it; no time left for planned maintenance.
No worked examples on this bot yet. Worked examples are optional but strongly recommended — they turn an abstract failure mode into something a developer can verify in a fixture.
6. Parameter Guide
| Parameter | Default | Warning | Hard | What it controls |
|---|
| slo_definitions | {'fill_latency_ms_p99': 500, 'fill_success_rate_pct': 99.5, 'uptime_pct': 99.9} | None | None | Map of SLO name to target value. |
| burn_rate_alert_pct | 5.0 | 10 | 20 | Alert when hourly error-budget burn rate exceeds this percentage of the monthly budget. |
7. Detailed Parameter Instructions
slo_definitions
What it means
Map of SLO name to target value.
Default
{ "slo_definitions": {"fill_latency_ms_p99": 500, "fill_success_rate_pct": 99.5, "uptime_pct": 99.9} }
Why this default matters
Default SLOs reflect the commitments in the Polytraders service agreement.
Threshold logic
| Condition | Action |
|---|
| metric_value violates slo_target | Increment error budget consumption; emit SLO_BREACH_DETECTED if budget exhausted |
Developer check
if metric_value > slo.target: budgetConsumer.record(slo.name)
User-facing English
The system maintains targets for response speed and availability.
burn_rate_alert_pct
What it means
Alert when hourly error-budget burn rate exceeds this percentage of the monthly budget.
Default
{ "burn_rate_alert_pct": 5.0 }
Why this default matters
5% hourly burn means the monthly budget would be exhausted in 20 hours.
Threshold logic
| Condition | Action |
|---|
| hourly_burn_rate > burn_rate_alert_pct | Emit SLO_BURN_RATE_EXCEEDED alert |
Developer check
if hourly_burn > p.burn_rate_alert_pct: emit('SLO_BURN_RATE_EXCEEDED')
User-facing English
You'll be notified if service quality degrades significantly.
8. Default Configuration
{
"bot_id": "gov.slamonitor",
"version": "0.1.0",
"mode": "shadow_only",
"defaults": {
"slo_definitions": {
"fill_latency_ms_p99": 500,
"fill_success_rate_pct": 99.5,
"uptime_pct": 99.9
},
"burn_rate_alert_pct": 5.0,
"publish_to_user": true,
"auto_freeze_on_breach": false
}
}
9. Implementation Flow
- Scrape Prometheus metrics from all fleet bots every 60 seconds.
- For each SLO definition, compute current compliance and error-budget consumption.
- Compute hourly burn rate as (errors_in_last_hour / monthly_budget * 100).
- If burn_rate > burn_rate_alert_pct, emit SLO_BURN_RATE_EXCEEDED alert.
- If error budget is exhausted, emit SLO_BREACH_DETECTED and optionally freeze deployments.
- Emit SettlementReport(event_type=SLO_STATUS) every hour with all SLO compliance metrics.
- Retain SettlementReport records for 7 years as compliance-grade availability evidence.
10. Reference Implementation
Pseudocode is language-agnostic. FETCH = read input. EMIT = produce output. IF/THEN/ELSE = decision. Translate directly to TypeScript, Python, Go, or Rust.
// ---- SCRAPE LOOP (every 60s) ----
FUNCTION scrapeAndEvaluate():
metrics = FETCH internal.metricsStore.GET({bots: 'all', window: '1m'})
IF metrics IS NULL:
EMIT SettlementReport(event_type='SLO_DATA_GAP')
alerting.emit('SLO_METRICS_UNAVAILABLE')
RETURN
compliance = {}
FOR slo IN config.slo_definitions:
actual = metrics.get(slo.name)
compliant = (actual <= slo.target) IF slo.type == 'max' ELSE (actual >= slo.target)
compliance[slo.name] = {target: slo.target, actual: actual, compliant: compliant}
IF NOT compliant:
errorBudget.record(slo.name, violation=True)
// ---- HOURLY REPORT ----
FUNCTION emitHourlyReport(windowStart, windowEnd):
burnRate = errorBudget.hourlyBurnRate()
IF burnRate > config.burn_rate_alert_pct:
alerting.emit('SLO_BURN_RATE_EXCEEDED', {burn_rate: burnRate})
IF errorBudget.exhausted():
alerting.emit('SLO_BREACH_DETECTED')
IF config.auto_freeze_on_breach:
deploymentManager.freeze()
EMIT SettlementReport(event_type='SLO_STATUS',
window_start=windowStart, window_end=windowEnd,
slo_compliance=compliance,
error_budget_consumed_pct=errorBudget.consumedPct(),
hourly_burn_rate_pct=burnRate,
retained_until=now() + days(2555))
SDK calls used
internal.metricsStore.GET({bots, window})errorBudget.hourlyBurnRate()alerting.emit('SLO_BURN_RATE_EXCEEDED', metadata)
Complexity: O(S) per scrape cycle where S = SLO count; O(1) for hourly report

"slo_name": "fill_latency_ms_p99",

}
17. Plain-English Reporting
| Situation | User-facing explanation |
|---|
| SLO status report published | Service quality is within the committed targets. All systems are operating normally. |
| SLO burn rate alert | Service quality has degraded and is consuming the error budget at a high rate. The team has been notified. |
18. Failure-Mode Block
| main_failure_mode | Metrics store is unavailable; SLO compliance cannot be computed; error budget calculation stalls. |
|---|
| false_positive_risk | A transient spike in fill latency causes a burn-rate alert that resolves in < 5 minutes. |
|---|
| false_negative_risk | A sustained SLO degradation below the burn-rate threshold goes unalerted. |
|---|
| safe_fallback | If metrics store is unavailable, emit SLO_STATUS with slo_compliance=unknown and alert on data gap. |
|---|
| required_dependencies | internal.metrics_store (Prometheus), internal.report_bus (ExecutionReport), Postgres SLO store |
|---|
19. Failure-Injection Recipes
| Scenario | How to inject | Expected behaviour | Recovery |
|---|
METRICS_STORE_UNAVAILABLE | Block reads from internal.metrics_store | | Automatic resume when metrics store recovers. |
HIGH_BURN_RATE | Inject 200 fill failures to exhaust fill_success_rate SLO budget | | Investigate and resolve fill failures; error budget resets monthly. |
AUTO_FREEZE_ON_BREACH | Set auto_freeze_on_breach=true; exhaust error budget | | Manual unfreeze after SLO remediation. |
20. State & Persistence
Cold-start recovery
On restart, reload error budget state from last committed SettlementReport.
21. Concurrency & Idempotency
| Aspect | Specification |
|---|
| Execution model | single-threaded scrape loop + hourly report goroutine |
| Max in-flight | 5 |
| Idempotency key | window_start |
| Per-call timeout (ms) | 10000 |
| Backpressure strategy | skip scrape if previous not complete |
| Locking / mutual exclusion | Postgres unique constraint on window_start for hourly reports |
22. Dependencies
Depends on (must run first)
| Bot | Why | Contract |
|---|
internal.metrics_store | All SLO compliance data is sourced from Prometheus metrics. | Metrics available with < 60s staleness. |
Emits to (downstream consumers)
| Bot | Why | Contract |
|---|
internal.post_trade_archive | | |
Sibling bots (same OrderIntent)
External services
| Service | Endpoint | SLA assumed | On failure |
|---|
| Internal metrics store (Prometheus) | https://metrics.internal | 99.9% | Emit SLO_DATA_GAP SettlementReport; alert; resume on recovery. |
23. Security Surfaces
Abuse vectors considered
- Manipulating metrics to suppress SLO breach detection
Mitigations
- Metrics store is read-only for SLAMonitor; write access is restricted to fleet bots only
24. Polymarket V2 Compatibility
| Aspect | Value |

| CLOB version | v2 |
| Collateral asset | pUSD |
| EIP-712 Exchange domain version | 2 |

Property Tests
| Property | Required behaviour |
|---|
| Every SLO status report is retained for >= 2555 days | Always true |
27. Operational Runbook
SLAMonitor incidents require rapid response when error budget burns faster than planned. P1 if budget is exhausted; P2 for high burn rate.
