Viewing Log Management

The log management page displays resource statistics, log applications, your favorite log streams/favorite log streams (local cache), alarm statistics, latest alarms, function release notices, and recently viewed log streams.

Resource Statistics

The Statistics area shows resource statistics and details by category in charts. The statistics are for reference only.

Log in to the LTS console. The Log Management page is displayed by default.
Under Overview, click Details in the upper right corner of the Statistics area to access the resource statistics details page.
Select a time range as required. By default, resource statistics display log resource data of one week (from now).
There are three types of time range: relative time from now, relative time from last, and specified time.
- 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: queries log data that is generated in a specified time range.

Billing for the log transfer function has commenced in regions CN North-Beijing1, CN Southwest-Guiyang1, CN East-Shanghai2, and CN East-Qingdao.
- Read/Write: LTS charges for the amount of compressed log data read from and written to LTS. Generally, the log compression ratio is 5:1.
- Index Traffic - Standard: Raw logs are full-text indexed (delimited) by default for log search. When logs are written to databases, traffic fees are charged at a time.
- Log: Space used for storing compressed logs, indexes, and copies is billed. The space is roughly the size of the raw logs.
  
  Standard storage statistics indicate the latest total storage volume within a specified time range.
- Raw Log Traffic: size of raw logs.
- Basic Transfer Traffic: traffic for transferring logs to OBS, DMS, and DIS. Such transfers do not require field mapping and consume less computing power. This parameter is displayed only when log transfer billing is enabled.
- Advanced Transfer Traffic: traffic for transferring logs to DWS and DLI. Such transfers require field mapping and consume more computing power. This parameter is displayed only when log transfer billing is enabled.
View the resource statistics of Log Groups (Top 100) and Log Streams (Top 100). You can select a time range and view the daily standard storage volume (GB), daily index traffic - standard (GB), daily basic transfer traffic (GB), daily advanced transfer traffic (GB), and daily read/write traffic (GB) in a table or bar chart based on the selected time range.

My Favorites/My Favorites (Local Cache)

This area displays the log streams you have added to favorites, including My Favorites and My Favorites(Local Cache).

My Favorites: Save log streams to the database. This function is disabled by default. If your account has the write permission, My Favorites and My Favorites(Local Cache) are displayed.
My Favorites(Local Cache): Save log streams to the local cache of the browser. This function is disabled by default. This parameter is displayed for both writable and read-only users.

If your account has the write permission, at least one of My Favorites and My Favorites(Local Cache) is enabled. Otherwise, log streams cannot be added to favorites.

Adding frequently used log streams to your favorites helps you quickly locate them.

The following example shows how to add a log stream of log group lts-test to favorites:

In the Log Groups list, click on the left of log group lts-test.
Click More > Edit in the Operation column of the target log stream. On the displayed dialog box, enable My Favorites and/or My Favorites(Local Cache) and click OK.
After the log stream is added to favorites, it is displayed in My Favorites/My Favorites(Local Cache) on the right.
