Release Highlights

Secrets Management

Keep collector credentials out of plain-text configuration files. Netdata now lets you reference secrets in collector configurations instead of storing them directly. Passwords, tokens, and API keys are resolved at runtime from the source you choose.

Resolvers

Netdata provides four resolver types, from simple to enterprise-grade:

Resolver	Syntax	Best For
Environment variable	${env:VAR_NAME}	Secrets already injected into the Netdata service environment
File	${file:/absolute/path}	Secrets stored in local files on disk (Docker Secrets, Kubernetes Secrets mounted as volumes)
Command	${cmd:/absolute/path args}	Secrets returned by a trusted local command (e.g., 1Password CLI, custom scripts)
Secretstore	${store:<kind>:<name>:<operand>}	Secrets managed centrally in cloud providers or Vault

Supported Secretstore Backends

For organizations managing secrets centrally, Netdata integrates with four secretstore backends:

Backend	Kind	Operand Format	Authentication Modes
AWS Secrets Manager	aws-sm	secret-name[#key]	Environment credentials, ECS task role, EC2 instance profile
Azure Key Vault	azure-kv	vault-name/secret-name	Service principal, Managed identity, Default credential chain
Google Secret Manager	gcp-sm	project/secret[/version]	Metadata server, Service account file
HashiCorp Vault	vault	path#key	Token, Token file

Configure secretstores through the Netdata Dynamic Configuration UI (Collectors → go.d → SecretStores) or via configuration files under /etc/netdata/go.d/ss/.

Example

A MySQL collector referencing its password from HashiCorp Vault:

:::yaml
# /etc/netdata/go.d/mysql.conf
jobs:

  - name: mysql_prod
    dsn: "netdata:${store:vault:vault_prod:secret/data/netdata/mysql#password}@tcp(127.0.0.1:3306)/"

You can mix resolver types freely. For example, read the username from an environment variable and the password from a secretstore in the same config value:

:::yaml
jobs:

  - name: mysql_prod
    dsn: "${env:MYSQL_USER}:${store:vault:vault_prod:secret/data/netdata/mysql#password}@tcp(127.0.0.1:3306)/"

How It Works

• Secrets are resolved each time a collector job starts or restarts.
• Updating a secretstore automatically restarts collector jobs that use it so they pick up new credentials.
• Secretstore configuration values themselves also support ${env:...}, ${file:...}, and ${cmd:...} resolvers, so backend credentials don't need to be stored in plain text either.

[!TIP] For detailed setup, backend-specific authentication guides, and troubleshooting, see the Secrets Management documentation.

Enhanced AI Conversations

Netdata AI Conversations are now more powerful. You can now add Active Alerts, Charts or AI-generated reports to start an AI conversation to provide better, more meaningful responses to your conversations.

Advanced Alerting

With this release, Netdata provides our users with the ability to:

• Graphically Evaluate Alerts on historical data before they are deployed

• Create complex recurrence rules on Alerts Silencing to manage your maintenance windows

• Acknowledge Alerts that your teams are working on

Improved Custom Dashboards

With this release, we have improved our custom dashboards support to:

• Add metrics charts, logs, live functions, events feeds, active alerts counts, node list, etc.
• Duplicate Dashboards to help create new custom dashboards from existing ones

Nagios Plugins Collector

Run Nagios-compatible plugins and custom scripts directly inside Netdata with the new Nagios Plugins collector. Any executable that follows the Nagios plugin output format works out of the box: packaged Nagios plugins, custom shell scripts, or compiled binaries.

What You Get

Feature	Details
Check State Monitoring	Tracks OK, WARNING, CRITICAL, and UNKNOWN states from the process exit code
Automatic Performance Data Charts	Nagios performance data values are parsed and charted automatically
Threshold-Based Alerting	When perfdata includes warning/critical thresholds, Netdata derives a threshold state chart (ok/warning/critical) and creates built-in alerts
Execution Metrics	Measures run duration, CPU time, and memory usage of each check
Nagios-Style Scheduling	Configurable check intervals, retry intervals, max check attempts, and time periods
Soft/Hard State Logic	Non-OK results retry at retry_interval up to max_check_attempts before triggering alerts, preventing false alarms from transient failures

Built-in Alerts

The collector ships with four stock alerts:

Alert	Triggers When
nagios_job_execution_state_warn	A check is in WARNING hard state
nagios_job_execution_state_crit	A check is in CRITICAL hard state
nagios_job_perfdata_threshold_state_warn	A perfdata metric exceeds its warning threshold
nagios_job_perfdata_threshold_state_crit	A perfdata metric exceeds its critical threshold

All stock alerts suppress soft retry states. Alerts fire only after the configured max_check_attempts consecutive failures.

Example

:::bash
# /usr/local/lib/netdata/checks/check_api.sh
#!/bin/sh
resp=$(curl -s -o /dev/null -w "%{http_code} %{time_total}" --max-time 5 "$1" 2>/dev/null)
code=$(echo "$resp" | cut -d' ' -f1)
time=$(echo "$resp" | cut -d' ' -f2)

[ "$code" -ge 500 ] && echo "CRITICAL - HTTP $code | response_time=${time}s;~:2;~:5" && exit 2
[ "$code" -ne 200 ] && echo "WARNING - HTTP $code | response_time=${time}s;~:2;~:5" && exit 1
echo "OK - HTTP $code | response_time=${time}s;~:2;~:5"
exit 0

:::yaml
# /etc/netdata/scripts.d/nagios.conf
jobs:

  - name: api_health
    plugin: /bin/sh
    args: ["/usr/local/lib/netdata/checks/check_api.sh", "http://localhost:8080/health"]
    check_interval: 1m
    retry_interval: 15s
    max_check_attempts: 3

This produces check state charts, execution metrics, and because the script emits perfdata with thresholds (response_time with warn >2s / crit >5s), an automatic response time chart with a threshold state chart and built-in alerts.

[!TIP] For the full setup guide, custom scripts walkthrough, and time period configuration, see the Nagios Plugins collector documentation.

Azure Monitor Collector

Monitor your entire Azure infrastructure from Netdata with the new Azure Monitor collector. It collects platform metrics from the Azure Monitor Metrics API with automatic resource discovery: point it at your subscriptions, and it finds your resources, matches them to built-in profiles (preconfigured sets of metrics), and starts collecting metrics.

[!IMPORTANT] This is an alpha feature. The configuration format may change in upcoming releases.

What You Get

Feature	Details
38 Built-in Service Profiles	1,300+ metrics across compute, databases, networking, storage, AI/ML, analytics, containers, and more
Automatic Discovery	Discovers resources via Azure Resource Graph and enables matching profiles without per-resource configuration
Multi-Subscription	Monitor resources across multiple Azure subscriptions in a single collector job
Flexible Discovery Scoping	Narrow discovery by resource groups, regions, or tags, or use a custom Azure Resource Graph KQL query
Built-in Alerts	Pre-configured alerts for critical Azure resource conditions
UI Configuration	Configure through the Netdata Dynamic Configuration UI without file editing

Supported Services

Category	Services via Profiles
Compute	Virtual Machine, Virtual Machine Scale Set, App Service (incl. Functions), Container Apps, Container Instances
Kubernetes	AKS
Databases	SQL Database, SQL Elastic Pool, SQL Managed Instance, MySQL Flexible, PostgreSQL Flexible, Cosmos DB, Cache for Redis
Networking	Load Balancer, Application Gateway, Front Door, Firewall, NAT Gateway, VPN Gateway, ExpressRoute Circuit, ExpressRoute Gateway
Storage & Analytics	Storage Account, Data Explorer, Data Factory, Stream Analytics, Synapse Analytics, Log Analytics
Messaging	Event Hubs, Service Bus, Event Grid, IoT Hub
AI & ML	Cognitive Services, Machine Learning, Application Insights
Integration	API Management, Logic Apps, Key Vault, Container Registry

[!TIP] For detailed setup instructions, authentication options, custom profiles, and tuning, see the Azure Monitor collector setup guide.
