# Configure knowledge graph SLOs using Terraform

Service level objectives (SLOs) in the [knowledge graph](/docs/grafana-cloud/knowledge-graph/) provide entity-centric service level monitoring with integrated root cause analysis capabilities. By using the `grafana_slo_provenance` label with the value `asserts`, you can create SLOs that display the “asserts” badge in the UI and enable the **Open RCA workbench** button for seamless troubleshooting.

For details about creating and managing SLOs in the knowledge graph UI, refer to [Create and manage the knowledge graph SLOs](/docs/grafana-cloud/knowledge-graph/configure/manage-slos/).

## Overview

Knowledge graph SLOs extend standard Grafana SLOs with entity-centric monitoring and root cause analysis features:

- **Entity-centric monitoring:** SLOs are tied to specific services, applications, or infrastructure entities tracked by the knowledge graph
- **RCA workbench integration:** The **Open RCA workbench** button enables deep-linking to pre-filtered troubleshooting views
- **Knowledge graph provenance badge:** SLOs display an “asserts” badge instead of “provisioned” in the UI
- **Search expressions:** Define custom search expressions to filter entities in RCA workbench when troubleshooting an SLO breach

## Before you begin

To create a knowledge graph SLO using Terraform, you need to:

- Configure the knowledge graph and have metrics flowing into Grafana Cloud
- [Set up Terraform for the knowledge Graph](../getting-started/)
- Possess knowledge of and have experience with defining SLOs, SLIs, SLAs, and error budgets
- Have an understanding of PromQL

## Create a basic knowledge graph SLO

Create a file named `kg-slo.tf` and add the following:

terraform ![Copy code to clipboard](/media/images/icons/icon-copy-small-2.svg) Copy

```terraform
# Basic knowledge graph SLO with entity-centric monitoring
resource "grafana_slo" "kg_example" {
  name        = "API Service Availability"
  description = "SLO managed by knowledge graph for entity-centric monitoring and RCA"

  query {
    freeform {
      query = "sum(rate(http_requests_total{code!~\"5..\"}[$__rate_interval])) / sum(rate(http_requests_total[$__rate_interval]))"
    }
    type = "freeform"
  }

  objectives {
    value  = 0.995
    window = "30d"
  }

  destination_datasource {
    uid = "grafanacloud-prom"
  }

  # Knowledge graph integration labels
  # The grafana_slo_provenance label triggers knowledge graph-specific behavior:
  # - Displays "asserts" badge instead of "provisioned"
  # - Shows "Open RCA workbench" button in the SLO UI
  # - Enables correlation with knowledge graph entity-centric monitoring
  label {
    key   = "grafana_slo_provenance"
    value = "asserts"
  }

  label {
    key   = "service_name"
    value = "api-service"
  }

  # Search expression for RCA workbench
  # This enables the "Open RCA workbench" button to deep-link with pre-filtered context
  search_expression = "service=api-service"

  alerting {
    fastburn {
      annotation {
        key   = "name"
        value = "SLO Burn Rate Very High"
      }
      annotation {
        key   = "description"
        value = "Error budget is burning too fast"
      }
    }
    slowburn {
      annotation {
        key   = "name"
        value = "SLO Burn Rate High"
      }
      annotation {
        key   = "description"
        value = "Error budget is burning too fast"
      }
    }
  }
}
```

## Configure an SLO with multiple entity labels

Configure SLOs with multiple entity labels for fine-grained filtering in RCA workbench:

terraform ![Copy code to clipboard](/media/images/icons/icon-copy-small-2.svg) Copy

```terraform
# Knowledge graph SLO with comprehensive entity labels
resource "grafana_slo" "payment_service" {
  name        = "Payment Service Latency SLO"
  description = "Latency SLO for payment processing with team and environment context"

  query {
    freeform {
      query = "histogram_quantile(0.99, sum(rate(http_request_duration_seconds_bucket{service=\"payment\"}[$__rate_interval])) by (le)) < 0.5"
    }
    type = "freeform"
  }

  objectives {
    value  = 0.99
    window = "7d"
  }

  destination_datasource {
    uid = "grafanacloud-prom"
  }

  # Knowledge graph provenance - required for RCA workbench integration
  label {
    key   = "grafana_slo_provenance"
    value = "asserts"
  }

  # Service identification
  label {
    key   = "service_name"
    value = "payment-service"
  }

  # Team ownership
  label {
    key   = "team_name"
    value = "payments-team"
  }

  # Environment
  label {
    key   = "environment"
    value = "production"
  }

  # Business unit
  label {
    key   = "business_unit"
    value = "fintech"
  }

  # Search expression with multiple filters
  search_expression = "service=payment-service AND environment=production"

  alerting {
    fastburn {
      annotation {
        key   = "name"
        value = "Payment Latency Critical"
      }
      annotation {
        key   = "description"
        value = "Payment service P99 latency exceeding SLO - immediate attention required"
      }
      annotation {
        key   = "runbook_url"
        value = "https://docs.example.com/runbooks/payment-latency"
      }
    }
    slowburn {
      annotation {
        key   = "name"
        value = "Payment Latency Warning"
      }
      annotation {
        key   = "description"
        value = "Payment service experiencing elevated latency"
      }
    }
  }
}
```

## Configure a Kubernetes service SLO

Configure knowledge graph SLOs for Kubernetes services with Pod and namespace context:

terraform ![Copy code to clipboard](/media/images/icons/icon-copy-small-2.svg) Copy

```terraform
# Knowledge graph SLO for Kubernetes service
resource "grafana_slo" "k8s_frontend" {
  name        = "Frontend Service Availability"
  description = "Availability SLO for frontend service in Kubernetes"

  query {
    freeform {
      query = "sum(rate(http_requests_total{namespace=\"frontend\",code!~\"5..\"}[$__rate_interval])) / sum(rate(http_requests_total{namespace=\"frontend\"}[$__rate_interval]))"
    }
    type = "freeform"
  }

  objectives {
    value  = 0.999
    window = "30d"
  }

  destination_datasource {
    uid = "grafanacloud-prom"
  }

  label {
    key   = "grafana_slo_provenance"
    value = "asserts"

  label {
    key   = "service_name"
    value = "frontend"
  }

  label {
    key   = "namespace"
    value = "frontend"
  }

  label {
    key   = "cluster"
    value = "prod-us-west-2"
  }

  # Search expression targeting Kubernetes entities
  search_expression = "namespace=frontend AND cluster=prod-us-west-2"

  alerting {
    fastburn {
      annotation {
        key   = "name"
        value = "Frontend Service Critical"
      }
      annotation {
        key   = "description"
        value = "Frontend service availability below SLO"
      }
      annotation {
        key   = "severity"
        value = "critical"
      }
    }
    slowburn {
      annotation {
        key   = "name"
        value = "Frontend Service Degraded"
      }
      annotation {
        key   = "description"
        value = "Frontend service showing signs of degradation"
      }
      annotation {
        key   = "severity"
        value = "warning"
      }
    }
  }
}
```

## Configure an API endpoint-specific SLO

Configure knowledge graph SLOs for specific API endpoints with request context:

terraform ![Copy code to clipboard](/media/images/icons/icon-copy-small-2.svg) Copy

```terraform
# Knowledge graph SLO for critical API endpoint
resource "grafana_slo" "checkout_api" {
  name        = "Checkout API Availability"
  description = "Availability SLO for /api/checkout endpoint"

  query {
    freeform {
      query = "sum(rate(http_requests_total{path=\"/api/checkout\",code!~\"5..\"}[$__rate_interval])) / sum(rate(http_requests_total{path=\"/api/checkout\"}[$__rate_interval]))"
    }
    type = "freeform"
  }

  objectives {
    value  = 0.9999
    window = "30d"
  }

  destination_datasource {
    uid = "grafanacloud-prom"
  }

  label {
    key   = "grafana_slo_provenance"
    value = "asserts"

  label {
    key   = "service_name"
    value = "checkout-service"
  }

  label {
    key   = "endpoint"
    value = "/api/checkout"
  }

  label {
    key   = "criticality"
    value = "high"
  }

  # Search expression with endpoint context
  search_expression = "service=checkout-service AND path=/api/checkout"

  alerting {
    fastburn {
      annotation {
        key   = "name"
        value = "Checkout API Critical Failure"
      }
      annotation {
        key   = "description"
        value = "Checkout API experiencing high error rates - revenue impact"
      }
      annotation {
        key   = "severity"
        value = "critical"
      }
      annotation {
        key   = "alert_priority"
        value = "P0"
      }
    }
    slowburn {
      annotation {

```terraform
# Variable for environment-specific configuration
variable "environment" {
  description = "Environment name"
  type        = string
}

variable "slo_target" {
  description = "SLO target percentage"
  type        = number
}

# Environment-aware knowledge graph SLO
resource "grafana_slo" "api_service" {
  name        = "${var.environment} - API Service Availability"
  description = "API service availability SLO for ${var.environment} environment"

  query {
    freeform {
      query = "sum(rate(http_requests_total{environment=\"${var.environment}\",code!~\"5..\"}[$__rate_interval])) / sum(rate(http_requests_total{environment=\"${var.environment}\"}[$__rate_interval]))"
    }
    type = "freeform"
  }

  objectives {
    value  = var.slo_target
    window = "30d"
  }

  destination_datasource {
    uid = "grafanacloud-prom"
  }

  label {
    key   = "grafana_slo_provenance"
    value = "asserts"
  }

  label {
    key   = "service_name"
    value = "api-service"
  }

  label {
    key   = "environment"
    value = var.environment
  }

  search_expression = "service=api-service AND environment=${var.environment}"

  alerting {
    fastburn {
      annotation {
        key   = "name"
        value = "${var.environment} API Critical"
      }
      annotation {
        key   = "description"
        value = "API service in ${var.environment} experiencing critical errors"
      }
    }
    slowburn {
      annotation {
        key   = "name"
        value = "${var.environment} API Warning"
      }
      annotation {
        key   = "description"
        value = "API service in ${var.environment} showing elevated errors"
      }
    }
  }
}
```

## Best practices

Follow these best practices when setting knowledge graph SLOs.

### Use the knowledge graph provenance label

- Always include the `grafana_slo_provenance` label with value `asserts` for knowledge graph-managed SLOs
- This label enables the “asserts” badge in the UI instead of “provisioned”
- It also enables the **Open RCA workbench** button for troubleshooting SLO breaches

### Define search expressions

- Define meaningful search expressions that filter relevant entities in RCA workbench
- The search expression defines which entities populate RCA workbench when you troubleshoot an SLO breach
- Use entity attributes like service name, environment, namespace, and cluster
- Combine multiple filters with `AND` operators for precise filtering
- Test search expressions in RCA workbench before codifying them in Terraform

### Add entity labels

- Add descriptive labels to track service ownership, environment, and criticality
- Use consistent label naming conventions across all SLOs
- Include team names to enable quick identification of ownership
- Tag critical business services with appropriate labels

### Set SLO targets

- Set realistic SLO targets based on service requirements and capabilities
- Use higher targets (0.999+) for critical user-facing services
- Consider different targets for different environments (production vs staging)
- Review and adjust targets based on actual service performance

### Add alert annotations

- Add comprehensive descriptions to help on-call engineers understand the alert
- Include runbook URLs in annotations for quick access to troubleshooting guides
- Set appropriate severity levels (critical, warning) based on business impact
- Customize alert names to clearly identify the affected service and issue

### Configure queries

- Use PromQL queries that accurately represent service health
- Exclude expected error codes, such as 404, from error calculations when appropriate
- Leverage rate intervals with `$__rate_interval` for dynamic time range support
- Test queries in Grafana before adding them to Terraform configurations

### Set compliance windows

- Use 30-day windows for production SLOs to align with monthly reporting
- Consider shorter windows (7d) for development or testing environments
- Ensure compliance windows align with business requirements and error budget policies

## Verify the configuration

After applying the Terraform configuration, verify that:

- SLOs are created in your Grafana Cloud stack
- SLOs appear in **Observability &gt; SLO** with the “asserts” badge
- The **Open RCA workbench** button is visible when you expand **Objective** for an SLO
- You can select a time range in the **Error Budget Burndown** panel and click **Open in RCA workbench**
- Search expressions correctly filter entities in RCA workbench
- Fast burn and slow burn alerts are configured with appropriate thresholds
- Labels are correctly applied and visible in the SLO details

## Troubleshooting

Follow these troubleshooting steps if you experience issues setting knowledge graph SLOs.

### SLO shows “provisioned” instead of “asserts” badge

Ensure the `grafana_slo_provenance` label is set to `asserts`:

terraform ![Copy code to clipboard](/media/images/icons/icon-copy-small-2.svg) Copy

```terraform
label {
  key   = "grafana_slo_provenance"
  value = "asserts"
}
```

### Open RCA workbench button not appearing

- Verify the `search_expression` field is populated
- The **Open RCA workbench** button appears after you have added a search expression in the **RCA workbench Context** section
- Ensure the search expression uses valid entity attributes
- Check that the knowledge graph is properly configured and receiving data

### Alerts not triggering

- Verify the PromQL query returns valid results in Grafana
- Check that the destination data source is correctly configured
- Ensure alerting blocks are properly defined with annotations
