compute_slo
Compute SLI/SLO metrics from InfluxDB query results.
Compute SLI/SLO metrics from InfluxDB query results.
Read-only · Calls external systems. Safe to call: this tool does not modify data.
Parameters
| Field | Type | Required | Description |
|---|---|---|---|
good_field | string | No | Field name for good events (default 'good') |
operator | string | Yes | Operator slug (= InfluxDB database name) |
precision | string | No | Query time precision (s, ms, u, ns) |
query | string | Yes | InfluxQL query returning good/total fields |
slo_target | number | Yes | SLO target percentage (e.g. 99.9) |
total_field | string | No | Field name for total events (default 'total') |
window | string | No | SLO window (default '30d'). Supported: Nd, Nh |
Example arguments
Illustrative arguments an agent supplies when calling this tool:
{
"operator": "string",
"query": "string",
"slo_target": 0
}Description
Uses Google SRE burn-rate methodology.
Prerequisite: Run query_metrics with SHOW MEASUREMENTS and SHOW FIELD KEYS first to discover which measurement contains success/failure counts.
Example: SELECT sum("number_success") AS good, sum("number_success") + sum("number_failed") AS total FROM "test" WHERE time > now() - 30d GROUP BY time(1d)
The tool extracts good/total fields, computes SLI, error budget, burn rate, and severity.
Severity thresholds (Google SRE):
- critical: burn rate > 14.4x (page immediately)
- red: burn rate > 6x (create ticket)
- yellow: burn rate > 1x (SLO at risk)
- green: burn rate <= 1x (within budget)Related
