Creating a Dashboard

This section describes how to create a dashboard on Cloud Log Service.

The dashboard supports real-time analysis of log data. Log results queried and analyzed through SQL statements can be displayed in various statistical charts, and multiple statistical charts can be saved to the dashboard simultaneously to provide a global view of data analysis and monitoring. This section describes how you can create a dashboard and the relevant operations.

Before You Begin

Logs have been collected and ingested and log data can be collected.
Logs have been structured.

Procedure

Log in to the Cloud Log Service console and select Dashboard–Dashboard List in the left navigation bar.
Click Create Dashboard to enter the dashboard creation page and enter a custom dashboard name.
Click OK to create the dashboard.

Configuring a Dashboard

Log in to the Cloud Log Service console, select Dashboard–Dashboard List in the left navigation bar, select the dashboard created in the previous step, and click on the dashboard name to enter the dashboard page.
On the dashboard page, click the Edit button in the upper right corner to edit a chart.
Click the Add Chart button in the upper right corner.
On the Add Chart page, select the specified log project and log unit, enter the query and analysis statements, and click Retrieve/Analysis to generate a chart.
You can modify the chart type and configure the chart on the right side. Currently, table charts, sequence charts, bar charts, pie charts, and flow charts are supported. After completing the chart configuration, click OK to add the chart to the dashboard.
After completing the chart configuration, click Save in the upper right corner of the dashboard page to save the current dashboard configuration.

Adding Filters

This section describes how to add filters to Cloud Log Service.

You can add filters to Cloud Log Service dashboards to query, filter, and replace variables on the entire dashboard.

Before You Begin

Logs have been collected and ingested and log data can be collected.
Logs have been structured.
You have created a dashboard and added a chart.

Filter Types

Currently, the following two types of filters are supported, and the type can be selected when you are creating the filter:

Type	Description	Effective Scope
Drop-down option filter	Filter the data of all charts in the dashboard by the field value of a specified field. When executing a filter, you need to add it as a filter condition before the query and analysis statements, and use AND or NOT to connect the filter to the statements. For example, Key = Value and [search query] means searching for logs containing Key= Value in the results of the original query and analysis statements.	Charts of all log topics in the dashboard.
Variable replacement filter	Variable replacement allows users to set variable values themselves and replace the corresponding values in the query analysis statement. If a statistical chart with the variable placeholder is already set in the dashboard, then after a filter of the variable type is added, the variables in the query and analysis statements are automatically replaced with the variable values you choose.	Charts using this variable in the dashboard.

Procedure

Log in to the Cloud Log Service console, select Dashboard–Dashboard List in the left navigation bar, select the specified dashboard, and click on the dashboard name to enter the dashboard page.
On the dashboard page, click the Edit button in the upper right corner to edit the dashboard.
Click Add Filter in the upper right corner.
On the Add Filter page, configure the relevant parameters for the filter. Two types of filters are supported. For specific parameter configurations, see the table below. After the filter is added, click Save in the upper right corner of the dashboard to complete the filter addition operation.

Parameter	Description
Filter Name	Custom filter name. Supports up to 32 characters.
Type	Select the filter type or the variable replacement type.
Query Modes	If you select theFiltertype, you need to specify the query method. It refers to the relationship between filter conditions and chart query statements. When performing the filter operation, you need to add it as a filter condition before the query and analysis statements. The method can be AND (default) or NOT. If you choose AND, then Key = Value and [search query]; If you choose NOT, then NOT Key = Value and [search query].
Filter Field	If you select theFiltertype, you need to specify the filter field. Only numbers, letters, underlines, hyphens (-), and dots (.) are allowed.
Variable Name	If you select theVariable Replacementtype, you need to configure the variable name. After the configuration is completed, you need to use the format of ${variable name} to reference the variable in the query analysis statement.
Static Option	Set the drop-down option value of the filter. The static options will be displayed permanently and support aliases. Click + to add multiple options. If the configuration is selected by default, this option value is used by default to execute filtering every time the dashboard is opened. It is recommended that you specify a default option value for variable replacement.
Dynamic Option	When it is enabled, you can add dynamic list items. Dynamic list items are the query results of custom queries and analysis statements. In different time ranges, the query results change dynamically, so the option values also change dynamically. You need to configure log projects, log units, query analysis statements and time ranges. Dynamic option values are obtained based on the above statistical analysis results.

Adding Charts

This section describes how to add visual charts to dashboards on Cloud Log Service.

Query analysis results can be saved to dashboards as charts for long-term monitoring.

Before You Begin

Logs have been collected and ingested and log data can be collected.
Logs have been structured.
You have created a dashboard.

Procedure

Log in to the Cloud Log Service console. Select the target log project and log unit, and click Retrieve Log to enter the search page.
Use the interaction mode to retrieve and filter logs, or use the statement mode to write a query analysis statement and construct an analysis scenario.
Click the Retrieve/Analyze button and the results will be presented in a table chart by default.
Click Icon Type on the right to convert the table to other chart types. Supports sequence charts, bar charts, pie charts and line charts.
Click the Add to Dashboard button. You can select a dashboard already created or add a new dashboard. Click OK , and the current chart will be added to the dashboard.
