Log Search
Follow the directions below to search logs by keyword and time range:
- On the LTS console, choose Log Management in the navigation pane on the left.
- In the log group list, click
on the left of a log group name.
- In the log stream list, click a log stream name.
- In the upper right corner, select a time range.
There are three types of time range: relative time from now, relative time from last, and specified time. Select a time range as required.
NOTE:
- From now: queries log data generated in a time range that ends with the current time, such as the previous 1, 5, or 15 minutes. For example, if the current time is 19:20:31 and 1 hour is selected as the relative time from now, the charts on the dashboard display the log data that is generated from 18:20:31 to 19:20:31.
- From last: queries log data generated in a time range that ends with the current time, such as the previous 1 or 15 minutes. For example, if the current time is 19:20:31 and 1 hour is selected as the relative time from last, the charts on the dashboard display the log data that is generated from 18:00:00 to 19:00:00.
- Specified time: queries log data that is generated in a specified time range.
- On the log stream details page, you can search for logs using the following methods:
- In the search area, click in the search box. The drop-down list contains the following items:
- Structured fields or index fields: Built-in fields are not displayed in the drop-down list. However, when you enter a built-in field, the drop-down list is automatically associated and matched with the field.
- NOT, AND, OR, :, and :* keywords can be displayed. Keywords other than NOT are displayed in the drop-down list only after you enter the keyword in the search box.
NOTE:
- When entering a keyword, you can press Tab to automatically add the first keyword displayed in the drop-down list.
- Keywords are case-insensitive.
- Historical records: A maximum of 20 historical records can be retained, but only the latest three records are displayed in the drop-down list.
- Quick search: quick search fields that have been created.
- Search syntax: common search syntax.
Enter a keyword, or select a field and keyword from the drop-down list, and click Query.
Logs that contain the keyword are displayed.
NOTE:
- Built-in fields include appName, category, clusterId, clusterName, collectTime, containerName, hostIP, hostIPv6, hostId, hostName, nameSpace, pathFile, podName and serviceID. By default, the fields are displayed in simplified mode, and hostIP, hostName, and pathFile are displayed at the beginning.
- The structured fields are displayed in key:value format.
- On the Raw Logs page, click a field in blue in the log content. You can select Copy, Add To Search, and Exclude from Search from the displayed drop-down list.
- Click a field for which quick analysis has been created to add it to the search box.
NOTE:
If the field you click already exists in the search box, it will be replaced by this newly added one. If the field is added for the first time, fields in the search box are searched using the AND operator.
- In the search area, press the up and down arrows on the keyboard to select a keyword or search syntax from the drop-down list, press Tab or Enter to select a keyword or syntax, and click Search.
- In the search area, click in the search box. The drop-down list contains the following items:
