  • osquery installed: osqueryd --version
  • Falco installed: falco --version
  • Git repository cloned: /home/john/loki exists
  • Adequate disk space: df -h /home (at least 10GB free)
  • Ports available: 3000 (Grafana), 3100 (Loki), 12345 (Alloy), 514 (syslog)

Step 1: osqueryd Setup

# Make script executable
chmod +x /home/john/loki/setup-osqueryd.sh

# Run complete setup (one command)
sudo /home/john/loki/setup-osqueryd.sh setup

# Verify
sudo systemctl status osqueryd  # Should show "active (running)"
sleep 5
sudo tail -20 /var/log/osquery/osqueryd.results.log  # Should see JSON logs

# Test basic queries
osqueryi
> SELECT * FROM system_info LIMIT 1;
> .quit

Checklist:

  • Script is executable
  • Setup completes without errors
  • Service is running
  • Log file exists and contains JSON data
  • Interactive queries work

If this fails, see OSQUERYD_TROUBLESHOOTING.md

Step 2: Loki Stack Setup

# Navigate to project directory
cd /home/john/loki

# Make start script executable
chmod +x start-loki.sh

# Start all services
./start-loki.sh start

# Wait for services to be ready (2-3 minutes)
# Watch the output for readiness messages

# Verify status
./start-loki.sh status
# OR
docker-compose ps

Expected services running:

  • loki (3100)
  • grafana (3000)
  • alloy (12345)
  • minio (9000)
  • nginx (gateway)
  • falco (container)
  • falcosidekick (container)

Checklist:

  • All services started successfully
  • No error messages in output
  • docker-compose ps shows all services as "up"

If this fails, check Docker daemon: docker info

Step 3: Verify Log Collection

3.1 Check Loki API

# Verify Loki is responding
curl -s http://localhost:3100/ready

# Expected output: "ready"

# List available log streams
curl -s http://localhost:3100/loki/api/v1/label/job/values | python3 -m json.tool

# Expected: ["osquery", "falco", "journal", "docker", etc.]

Checklist:

  • Loki responds to /ready
  • Job labels are present

3.2 Verify osquery Logs in Loki

# Query osquery logs
curl -s 'http://localhost:3100/loki/api/v1/query?query={job="osquery"}' | python3 -m json.tool

# Should return results

Checklist:

  • Query returns results (might take a minute)
  • Results are JSON formatted

3.3 Verify Alloy is running

# Check Alloy container
docker-compose logs -f alloy

# Watch for "Loki client started" or similar messages

Checklist:

  • Alloy container shows no errors
  • Alloy logs show it's forwarding data

Step 4: Grafana Setup

# Access Grafana
# Browser: http://localhost:3000
# Username: admin
# Password: admin

# Or from CLI:
curl -s -u admin:admin http://localhost:3100/api/datasources | python3 -m json.tool

Grafana Checklist:

  • Login successful (admin/admin)
  • Loki datasource is available
  • Datasource name is "Loki"

4.1 Test Queries in Grafana

  1. Go to Explore (left sidebar)
  2. Select Loki datasource
  3. Try these queries:
# All osquery logs
{job="osquery"}

# Falco alerts
{job="falco"}

# System journal
{job="journal"}

# Docker logs
{job="docker"}

# Specific patterns
{job="osquery"} | json | listening_port > 0

Checklist:

  • All queries return results
  • Results populate within a few seconds

Step 5: Test Detection & Alerting

5.1 Generate a Test Detection (Falco)

# Falco is already watching system calls
# Trigger a simple detection:
cat /etc/shadow 2>/dev/null || echo "Falco may have detected this"

# In Grafana Explore, query:
{job="falco"}

Checklist:

  • Falco alerts appear in Loki within a few seconds

5.2 Verify osqueryd Scheduled Queries

# Tail osqueryd log to see scheduled query results
sudo tail -f /var/log/osquery/osqueryd.results.log

# Should see JSON with columns like: system_info, processes, listening_ports, etc.
# Press Ctrl+C after 10 seconds

Checklist:

  • Query results appear in log
  • Results are valid JSON
  • Contains expected fields

Step 6: Verify Persistence & Auto-Start

# Restart osqueryd
sudo systemctl restart osqueryd

# Should come back online
sudo systemctl status osqueryd

# Restart Docker stack
cd /home/john/loki
./start-loki.sh restart

# All containers should restart
docker-compose ps

Checklist:

  • osqueryd restarts successfully
  • All Docker services restart successfully
  • Services come back online and generate logs

Step 7: Performance & Resource Monitoring

# Monitor osqueryd resource usage
sudo top -p $(pidof osqueryd)

# Expected: CPU <5%, Memory <2%

# Monitor Docker resources
docker stats

# Expected: No service using excessive resources

# Check disk usage
df -h /var/log/osquery/
du -sh /home/john/loki/.data/

# Expected: osquery logs <100MB, Loki data <500MB (initially)

Checklist:

  • osqueryd uses reasonable resources
  • Docker services healthy
  • Adequate disk space available

Step 8: Security & Configuration

8.1 Default Credentials (Change Before Production!)

# Current defaults:

# MinIO: loki/supersecret
# Loki: anonymous access enabled (via nginx gateway)

# To change Grafana password:
# 1. Log in to Grafana
# 2. Click admin icon (top right)
# 3. Change password

# To change MinIO credentials:
# Edit .env file and restart services
vi /home/john/loki/.env
docker-compose restart

Checklist:

  • You are aware of default credentials
  • Plan to change before production use

8.2 Check Configuration Files

# Review key configuration files
cat /home/john/loki/alloy-local-config.yaml | head -50
cat /etc/osquery/osquery.conf | python3 -m json.tool | head -50

# Verify no sensitive data in git repo
grep -r "password\|secret\|key" /home/john/loki --include="*.yaml" --include="*.json"

# Should have minimal results (all generic/documented)

Checklist:

  • Configurations reviewed
  • No hardcoded secrets in repo
  • All references to logs/configs documented

Step 9: Documentation Review

# Read key documentation
cat /home/john/loki/README.md
cat /home/john/loki/QUICKSTART.md
cat /home/john/loki/OSQUERYD_QUICK_START.md

Checklist:

  • You understand the architecture
  • You know how to start/stop services
  • You know where to find logs
  • You understand what's being monitored

Troubleshooting Quick Reference

Service won't start

# Check logs
docker-compose logs loki  # or alloy, grafana, falco, etc.

# Check ports
sudo netstat -tlnp | grep -E "3000|3100|12345|514"

# Restart Docker daemon
sudo systemctl restart docker

No logs appearing in Grafana

# Check Alloy is running
docker-compose logs alloy

# Check osqueryd is running
sudo systemctl status osqueryd

# Check log files exist
ls -la /var/log/osquery/
sudo tail -20 /var/log/osquery/osqueryd.results.log

Performance issues

# Check resource usage
docker stats
sudo top -p $(pidof osqueryd)

# Check disk space
df -h

# Review osquery config intervals - might need adjustment
# Disable heavy queries: process_memory_map, process_open_pipes

Loki API:

Pending Configuration

Alloy (Log Collector) - Config Fix Needed

The Alloy configuration has syntax errors due to:

  1. JSON metadata keys with underscores in Alloy HCL context
  2. Batch settings using commas instead of proper HCL syntax

Current Issues:

  • discovery.relabel rule using JSON-style metadata keys
  • loki.write batch settings not properly formatted

Resolution: Update alloy-local-config.yaml to use valid Alloy HCL syntax

Falcosidekick

  • Port 2801 already in use (remaining process)
  • Will resolve after cleanup

Current Resource Usage

osqueryd

Status: active (running)
CPU: <1%
Memory: ~16 MB
Threads: 2

Docker Stack

Grafana: ~70 MB RAM
Loki (backend): ~50 MB RAM  
Loki (write): ~45 MB RAM
Loki (read): ~40 MB RAM
MinIO: ~80 MB RAM
Alloy: Not running (config issue)

Disk Usage

/var/log/osquery/: ~1 KB (will grow slowly with optimized config)
/home/john/loki/.data/: ~100 MB (MinIO storage)

Step 1: Fix Alloy Configuration

Fix the syntax errors in /home/john/loki/alloy-local-config.yaml:

# Option 1: Auto-fix (recommended)
sed -i 's/__meta_osquery_source/_osquery_source/g' alloy-local-config.yaml

Step 2: Restart Alloy

docker-compose restart alloy

Step 3: Verify Log Flow

# Check Alloy logs
docker-compose logs alloy

# Verify osquery is being collected
curl -s 'http://localhost:3100/loki/api/v1/query?query={job="osquery"}'

Step 4: Fix Falcosidekick

# Kill remaining process
sudo pkill -f falcosidekick

# Restart service
docker-compose restart falcosidekick

SSD Optimization Features Implemented

    • Process execution events
    • Network connections
    • User logins (already visible in logs)

  2. Set up Grafana alerting rules for:

    • Suspicious processes
    • Unauthorized access attempts
    • Configuration changes

  3. Tune osquery schedule based on your needs:

    • Enable/disable queries in /etc/osquery/osquery.conf
    • Adjust intervals for frequently needed data
    • Check performance with ps aux | grep osqueryd and top

Medium-term (Month 1)

  1. Configure Loki retention policy:

    • Edit loki-config.yaml retention_period setting
    • Run docker-compose restart backend write

  2. Set up persistent backups of:

    • MinIO data (.data/ directory)
    • osquery results log (if long-term archival needed)

  3. Review and update Falco rules for your environment:

    • Edit falco-config.yaml
    • Restart Falco: docker-compose restart falco

  4. Document your monitoring setup for team knowledge base

Optimization Already Applied

osquery worker threads reduced to 2
Memory limits applied (5% of system RAM)
Cache moved to /tmp (RAM)
Heavy queries moved to longer intervals (daily/8h/12h)
Resource-intensive queries disabled or scheduled infrequently

Support & Debugging

Most Common Issues & Solutions

Issue: Alloy not collecting logs

# Check Alloy config syntax
docker-compose restart alloy
docker-compose logs alloy | grep -i error

# Check file permissions
sudo ls -l /var/log/osquery/osqueryd.results.log

Issue: Grafana can't query Loki

# Verify datasource
curl -s "http://localhost:3100/loki/api/v1/labels" \
  -H "X-Scope-OrgID: tenant1"

# Check Grafana logs
docker-compose logs grafana | tail -50

Issue: High disk writes from osqueryd

# Check current query count
grep -c '"name"' /var/log/osquery/osqueryd.results.log

# Review configuration
sudo cat /etc/osquery/osquery.conf | grep -A 5 "schedule"

# Reduce query frequency (edit /etc/osquery/osquery.conf and restart)

Issue: Loki disk usage growing too fast

# Check MinIO data size
du -sh /home/john/loki/.data/

# Review Loki retention policy
grep -A 5 "retention_period" loki-config.yaml

Check Disk Usage: du -sh /var/log/osquery/ # osquery logs du -sh /home/john/loki/.data/ # Loki storage

================================================================================ FIRST STEPS TO MONITOR

  1. Open Grafana http://localhost:3000 Login: admin/admin

  2. Navigate to Explore Loki should be selected as datasource

  3. Run a query {job="osquery"} Click "Run Query" See logged osquery events

  4. Try these sample queries: {job="osquery", name="logged_in_users"} # User login events {job="osquery", name="processes"} # Running processes {job="osquery", name="system_info"} # System information

================================================================================ IMMEDIATE ACTIONS (RECOMMENDED)

HIGH PRIORITY:

  1. Change Grafana password (Admin > Users > admin)
  2. Update MinIO credentials (if exposing externally)
  3. Test log queries in Grafana Explore

MEDIUM PRIORITY: 4. Create monitoring dashboards for your environment 5. Set up alerting rules in Grafana 6. Review and tune osquery queries if needed 7. Verify Falco rules are appropriate for your system

LONG-TERM: 8. Configure log retention policy in Loki 9. Set up automated backups of /home/john/loki/.data/ 10. Create runbooks for common issues 11. Monitor disk growth: du -sh /home/john/loki/.data/

================================================================================ TROUBLESHOOTING

Issue: osquery logs not appearing in Grafana Check: curl -s "http://localhost:3100/loki/api/v1/labels"
-H "X-Scope-OrgID: tenant1" Verify: docker-compose logs alloy | grep -i error Fix: docker-compose restart alloy

Issue: Grafana shows "No data" Check datasource health in Grafana admin panel Verify Loki gateway: docker-compose logs gateway Check logs are being collected: sudo tail -f /var/log/osquery/osqueryd.results.log

Issue: Alloy not starting Check config syntax: docker-compose logs alloy | grep "Error:" Verify file exists: ls -la /var/log/osquery/osqueryd.results.log Restart: docker-compose restart alloy

Issue: High disk usage Check osquery: du -sh /var/log/osquery/ Check Loki: du -sh /home/john/loki/.data/ Adjust retention in loki-config.yaml if needed
