Log applications for basic service monitoring

JuiceFS access analysis

This section introduces JuiceFS access analysis, a basic service monitoring log application provided in the TLS application marketplace.

Overview

Log observability capabilities built on JuiceFS support the detection and analysis of attacks on JuiceFS.

Access log analysis overview: Performs in-depth analysis and visualization of JuiceFS access logs, extracting key metrics for read, write, and delete operations, such as IO size distribution and repeated read/write information.

Access log analysis details: Performs in-depth analysis and visualization of JuiceFS access logs, covering statistics for read and write operations, repeated read/write, delete size, and other key metrics including their proportions and size information.

Monitoring chart details

The chart details for JuiceFS access analysis in TLS are as follows:

Access log analysis overview

Type	Chart
Write IO	Actual write size—including Cover write, write IO size distribution, Cover write size File sequential write ratio—distribution (operation count), Cover write time ratio
Read IO	Total read size, read IO size distribution, total repeated read size Repeated read time ratio, file sequential read ratio—distribution (operation count)
Deletion status	Total deletion size File lifecycle distribution Summary of read, write, and delete operations

Access log analysis details

Type	Chart
Overview	Proportion of cover writes to actual writes Proportion of repeated reads to total read size Proportion of deletion size to actual write size (excluding cover writes)
Write IO	Actual write size – including cover writes, actual write size – excluding cover writes Cover write size, proportion of cover write size, proportion of cover write time Write operation statistics, write IO size distribution, write IO duration distribution, write operation details, file write size Flush operation statistics excluding operations with duration less than 20 ms, flush IO duration distribution (excluding operations less than 20 ms), flush operation details File sequential write ratio – distribution (data size), file sequential write ratio – distribution (operation count) Sequential write ratio by file ID – data size, sequential write ratio by file ID – operation count
Read IO	Total read size, read operation statistics, read IO size distribution, read IO duration distribution, read operation details, file read size Total repeated read size, proportion of repeated read size, proportion of repeated read time, repeated read size File sequential read ratio – distribution (data size), file sequential read ratio – distribution (operation count) Sequential read ratio by file ID – data size, sequential read ratio by file ID – operation count
Deletion status	Total deletion size, deletion operation statistics, deletion IO size distribution, deletion duration distribution, deleted file size Number of files deleted but not created, details of files deleted but not created File lifecycle distribution
Summary of read, write, and delete	Top operations

Integrate log applications

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

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

On the Application marketplace tab, select the log application card to be integrated. For example, on the JuiceFS access analysis card, click Integrate application.

Configure the integration application parameters, then click Integrate application.

Parameters	Description
Name	Name of the integrated log application.
Description	Description of the integrated log application.
Region	Region of the integrated log application.
Log project	Select the log project to store the data.
Report center	Select the reports to generate. For example, in this case, select Access log analysis overview, Access log analysis details, then set the following parameters: Dashboard name: Set the dashboard name corresponding to the report. Log topic: Select the log topic as the data source. Field validation: The system automatically matches the corresponding index fields in the log topic based on the log application type. If some fields are missing, field types differ, or statistics are not enabled, manually replace the fields. Dashboard field description. For details, see Log field description for preset dashboard.

After successful integration, the dashboard page is displayed by default.

Manage my applications

After successfully integrating a log application, you can perform management operations on the integrated log applications:

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

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

Go to the My applications tab. In the Actions column for the corresponding log application, the following management operations are supported:

Operation	Description
Access management	Click Access management to enter the Access management tab, where you can modify the name and description of the connected log application.
Cancel access	Click Cancel access, confirm the information in the cancel access pop-up window, and then click Cancel access again.
View in dashboard	Click View in dashboard to enter the corresponding dashboard page and view related monitoring information in the dashboard. You can perform operations such as Add chart. For details, see Common dashboard actions.
