### 5. SLO Dashboard
Create comprehensive SLO dashboards:
**Grafana Dashboard Configuration**
```python
def create_slo_dashboard():
"""Generate Grafana dashboard for SLO monitoring"""
return {
"dashboard": {
"title": "Service SLO Dashboard",
"panels": [
{
"title": "SLO Summary",

### 6. SLO Reporting
Generate SLO reports and reviews:
**SLO Report Generator**
```python
class SLOReporter:
def __init__(self, metrics_client):
self.metrics = metrics_client
def generate_monthly_report(self, service, month):
"""Generate comprehensive monthly SLO report"""
report_data = {
'service': service,

slos['availability'] = {
'target': 99.9,

'met': self.metrics.query(availability_query) >= 99.9
}
# Latency SLO
latency_query = f"""
quantile_over_time(0.95,

```
### 7. SLO-Based Decision Making
Implement SLO-driven engineering decisions:
**SLO Decision Framework**
```python
class SLODecisionFramework:
def __init__(self, error_budget_policy):
self.policy = error_budget_policy
def make_release_decision(self, service, release_risk):
"""Make release decisions based on error budget"""

'medium_risk': 'approve',
'high_risk': 'review'
},
'attention': {
'low_risk': 'approve',
'medium_risk': 'review',
'high_risk': 'defer'
},
'warning': {

def prioritize_reliability_work(self, service):
"""Prioritize reliability improvements based on SLO gaps"""
slo_gaps = self.analyze_slo_gaps(service)
priorities = []

# If meeting SLOs, can afford more toil
# If not meeting SLOs, need to reduce toil
base_toil_percentage = 50 # Google SRE recommendation

# Exceeding SLO, can take on more toil
toil_budget = base_toil_percentage + 10

```python
class SLOTemplates:
@staticmethod
def get_api_service_template():

### 9. SLO Automation
Automate SLO management:
**SLO Automation Tools**
```python
class SLOAutomation:
def __init__(self):
self.config = self.load_slo_config()

### 10. SLO Culture and Governance
Establish SLO culture:
**SLO Governance Framework**
```python
class SLOGovernance:
def establish_slo_culture(self):
