Log applications for basic service monitoring

MQTT monitoring

This section introduces the MQTT monitoring log application for basic service monitoring provided by the TLS application marketplace.

Overview

Based on the standard OpenTelemetry protocol, the call chain flame graph displays the full link status of MQTT message requests, as well as statistics on the number of requests, number of errors, and error rate.

Monitoring chart details

The details of the TLS MQTT call chain observability monitoring charts are as follows:

Type	Chart
Performance overview analysis	Number of requests, top 5 services by number of requests, requests per minute Number of errors, top 5 services by number of errors, errors per minute Error rate, top 5 services by error rate, error rate per minute Average latency, top 5 services by average latency, average request latency P95 latency, top 5 services by P95 latency, average P95 request latency
Call chain analysis	Display information such as TraceId, status, total latency, start time, end time, and other information

Integrate log application

In the top navigation bar, select the region where TLS is located.

In the left navigation pane, select Common features > Log applications.

On the Marketplace tab, select the log application card to be integrated. For example, on the MQTT card, click Integrate application.

Configure the integration application parameters, then click Integrate application. The system will automatically redirect to the MQTT console of the Cloud Native Message Engine.

Configure the instance in the MQTT console.

Create an MQTT instance, create a Trace instance for the MQTT instance, configure message tracing, and configure the project. For details, see Integrate MQTT Trace with TLS.

View monitoring charts.

Return to the TLS console, go to the Marketplace tab, on the MQTT card, click View integration list, and click the name of the integrated log application to view the MQTT call chain observability monitoring charts.

Note

You can view the corresponding Trace instance in the TLS console. For details, please refer to Manage trace instances.

Delete my application

After the log application is successfully integrated, you can manage the integrated log application:

In the top navigation bar, select the region where TLS is located.

In the left navigation pane, select Common features > Log applications.

Go to the Marketplace tab, on the MQTT card, click View integration list.

In the Actions column of the corresponding log application, click Delete. In the delete pop-up window, confirm deletion of the log application, and click Delete again.

Note

After deleting an integrated MQTT application, the corresponding Trace instance for MQTT in TLS will be deleted synchronously, but the MQTT instance created in the MQTT console will not be deleted.
