Service Monitoring

The Service section is where you configure Agents to monitor external websites or servers.
Once a service monitor is set up, you can view the availability results from the past 30 days by clicking the Service icon on the homepage.

How to Use

Add a New Service Monitor

Follow these steps to add a new service monitor:

1. Access the Admin Panel
   Go to the Services page and click the + button to add a new service monitor.

2. Configure Parameters
   When adding a monitor, fill in the following details:

   • Name: Give the service a custom name.
   • Target: Set the target based on the monitoring type:
     • HTTP GET: Enter a complete URL (including http:// or https://), e.g., https://example.com.
       Note: If the target URL uses https://, Nezha Monitoring will also monitor its SSL certificate. Notifications will be triggered for certificate expiration or changes.
     • ICMP Ping: Enter a domain or IP address (without a port number), e.g., 1.1.1.1 or example.com.
     • TCP Ping: Enter a domain or IP address with a port number, e.g., 1.1.1.1:80 or example.com:22.
   • Type: Choose the monitoring type (HTTP GET, ICMP Ping, or TCP Ping).
   • Display in Services: Choose whether this monitor is visible to guest users (privacy option).
   • Interval: Set the monitoring interval (in seconds).
   • Coverage Scope: Select a rule to determine which Agents will request the target.
   • Specific Servers: Specify which Agents within the coverage scope will perform the monitoring.
   • Notification Group ID: Choose a pre-configured notification method from the Notifications page. See Notification Configuration for details.
   • Enable Failure Notification: Optionally enable notifications for target failures (disabled by default).

3. Submit the Monitor
   Click the Submit button to save the configuration. Wait a few moments, then check the homepage for monitoring results.

Delay Change Notifications

Nezha Monitoring tracks and records the latency between Agents and target servers. When significant latency changes occur, notifications can be sent to help monitor network conditions.

• Enable Delay Notification: Once enabled, notifications will be sent when latency exceeds the specified range (Max Latency or Min Latency).

---

Trigger Tasks on Notifications

To execute specific tasks when a service monitor triggers a notification:

1. Check the Enable Trigger Tasks option.
2. Configure:
   • Tasks on Alarm Trigger: Select the task to execute when an alarm is triggered.
   • Tasks on Recovery: Select the task to execute when the service returns to normal.

Tasks must be pre-configured in the Tasks page before using this feature.

Network Latency Charts

For TCP-Ping and ICMP-Ping monitoring types, the Dashboard automatically generates network latency charts:

• Open the details page of the target server and switch to the Network tab.
• View historical network latency trends. Data is based on real-time latency statistics between the Agent and the target server.
