LogTide vs Azure Monitor Logs

Azure Monitor with Log Analytics is Microsoft’s observability platform for Azure workloads. LogTide is a self-hosted, open-source alternative with built-in SIEM. Here’s how they compare.

Cost Comparison

Azure Monitor is one of the most expensive log management options in the cloud.

Azure Monitor Pricing

Component	Cost
Log Analytics ingestion (pay-as-you-go)	$2.76/GB
Log Analytics ingestion (commitment tier, 100 GB/day)	$1.96/GB
Data retention (first 31 days)	Included
Data retention (additional)	$0.10/GB/month
Basic Logs ingestion	$0.55/GB
Basic Logs queries	$0.006/GB scanned
Microsoft Sentinel (SIEM add-on)	$2.46/GB

Real-world example: An Azure SaaS company ingesting 50 GB/day:

• Log Analytics (commitment tier): 1,500 GB × $1.96 = $2,940/month
• Extra retention (90 days): ~$300/month
• Total: ~$3,240/month ($38,880/year)

With Sentinel SIEM added:

• Sentinel: 1,500 GB × $2.46 = $3,690/month
• Total with SIEM: ~$6,930/month ($83,160/year)

LogTide Pricing

Component	Cost
Software license	Free (AGPLv3)
Azure VM (Standard_D8s_v5)	~$280/month
Managed disk (1 TB Premium SSD)	~$120/month
SIEM features	Included
Users	Unlimited

Same 50 GB/day scenario on Azure infrastructure:

• VM + storage: ~$400/month
• Total: ~$400/month ($4,800/year)

Savings: ~$34,080/year (88%)

With SIEM comparison: Savings: ~$78,360/year (94%)

Feature Comparison

Feature	Azure Monitor	LogTide
Log ingestion	Yes (agents, APIs)	Yes (HTTP + SDKs)
Full-text search	KQL queries	Yes (real-time)
Query language	KQL (Kusto)	SQL + Sigma rules
Real-time streaming	Limited	SSE (included)
Alert rules	Yes (complex conditions)	Built-in
Dashboards	Azure Workbooks	SIEM dashboard
SIEM	Sentinel ($2.46/GB extra)	Built-in (included)
Sigma detection rules	Sentinel only	Built-in
MITRE ATT&CK mapping	Sentinel only	Included
Playbooks/automation	Logic Apps (extra cost)	Webhooks
Self-hosted	No (Azure only)	Yes
Open source	No	AGPLv3

Where Azure Monitor Wins

Native Azure integration. Azure Monitor collects data from every Azure service automatically — VMs, App Service, AKS, SQL Database, Functions. No agent configuration for most services.

KQL query language. Kusto Query Language is powerful for log analytics, with joins, aggregations, time-series analysis, and visualization. It’s one of the most capable query languages for log data.

Azure Workbooks. Rich, interactive dashboards with parameterized queries, conditional visibility, and embedded Azure resource context.

Sentinel integration. Microsoft Sentinel provides enterprise SIEM with hundreds of pre-built detection rules, Microsoft threat intelligence, and automated response playbooks — if you can afford it.

Compliance certifications. Azure Monitor carries SOC2, ISO 27001, HIPAA, and FedRAMP certifications for regulated industries.

Where LogTide Wins

Cost. Azure Monitor’s $2.76/GB ingestion is the highest among major cloud providers. LogTide saves 85-95% at typical volumes. Even with commitment tiers, the savings are dramatic.

SIEM included. Sentinel adds $2.46/GB on top of Log Analytics costs. LogTide includes Sigma detection rules, MITRE ATT&CK mapping, and incident management at zero additional cost.

No vendor lock-in. Azure Monitor uses KQL and proprietary data formats. LogTide stores data in PostgreSQL — standard SQL, exportable, portable.

Multi-cloud. LogTide runs on any cloud or on-premises. If you use Azure alongside AWS or GCP, LogTide provides unified log management.

Unlimited queries. Basic Logs in Azure Monitor charge per query ($0.006/GB). LogTide queries are unlimited. For frequent debugging and investigation, this matters.

Data ownership. With LogTide self-hosted, your logs never leave your infrastructure. Full control over data residency, retention, and access.

When to Choose Azure Monitor

• You run exclusively on Azure and want zero-config collection
• You need Sentinel for enterprise SIEM with Microsoft threat intelligence
• Your organization has Microsoft Enterprise Agreement discounts
• You need FedRAMP or specific Azure compliance certifications
• Budget is not a primary concern and convenience is valued

When to Choose LogTide

• Log volume exceeds 20 GB/day (significant cost difference even at small volumes)
• You need SIEM without Sentinel’s per-GB pricing
• You run multi-cloud or hybrid infrastructure
• You want to avoid Azure’s complex pricing tiers
• Data sovereignty requires self-hosted log management
• You prefer open-source with no vendor lock-in

Migration Path

Step 1: Deploy LogTide on Azure

# Create a VM
az vm create \
  --resource-group logtide-rg \
  --name logtide-server \
  --image Ubuntu2204 \
  --size Standard_D4s_v5 \
  --admin-username azureuser \
  --generate-ssh-keys

# Or deploy on AKS
kubectl apply -f logtide-deployment.yaml

Step 2: Dual Ship During Evaluation

Configure your applications to send logs to both Azure Monitor and LogTide:

import { LogTideClient } from '@logtide/node';

const logtide = new LogTideClient({
  dsn: process.env.LOGTIDE_DSN!,
  service: 'my-service',
});

// Existing Azure Application Insights continues
// LogTide also receives events
logtide.info('Request processed', { path: '/api/users', status: 200 });

Step 3: Forward via Event Hub

For existing Azure Monitor data, export to Event Hub and consume into LogTide:

# Create diagnostic setting to export to Event Hub
az monitor diagnostic-settings create \
  --name export-to-logtide \
  --resource /subscriptions/.../resourceGroups/.../providers/... \
  --event-hub logtide-logs \
  --event-hub-rule /subscriptions/.../providers/Microsoft.EventHub/namespaces/.../authorizationRules/RootManageSharedAccessKey \
  --logs '[{"category":"AppServiceHTTPLogs","enabled":true}]'

Step 4: Reduce Log Analytics Retention

Once validated, reduce retention and switch off unnecessary data collection:

az monitor log-analytics workspace update \
  --resource-group logtide-rg \
  --workspace-name your-workspace \
  --retention-time 30
