Viewing Log Management¶
The log management page displays resource statistics, your favorite log streams/favorite log streams (local cache), alarm statistics, latest alarms, 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 management console and choose Management & Deployment > Log Tank Service. 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.
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: queries log data that is generated in a specified time range.
View the resource statistics.
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: Raw logs are full-text indexed (delimited) by default for log search.
Log: Space used for storing compressed logs, indexes, and copies is billed. The space is roughly the size of the raw logs.
Raw Log Traffic: size of raw logs.
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 (GB), and daily read/write traffic (GB) in a table or bar chart based on the selected time range.
For a new log group or log stream, resource statistics will be collected in at least one hour.

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.
