Viewing Log Management

Resource Statistics

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

The Advanced button is available only to whitelisted users. To use it, choose Configuration Center in the navigation pane of the LTS console, click the Quota Configuration tab, and enable LTS Observability. For details, see Setting LTS Log Collection Quota and Usage Alarms.

• Basic: displays log resource statistics and log details.
• Advanced: displays the resource usage details and top log groups or streams by resource usage.

The LTS observability function is available only to whitelisted users in regions CN North-Beijing4, CN East-Shanghai1, CN South-Guangzhou, and AP-Singapore. To use it in these regions, submit a service ticket.

1. Log in to the LTS console.
2. Under Overview on the Log Management page, click Detailsor Details - Basic to access the resource statistics details page.

   The Details - Basic button is displayed only after the LTS observability function (available only to whitelisted users) is enabled.

3. Select a time range as required. By default, log resource statistics of the past seven days are displayed.

   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.

4. 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 - 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.
   • Standard Storage Volume: Space used for storing compressed logs, copies, and indexes 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.

5. View the resource statistics of Log Groups (Top 100) and Log Streams (Top 100). You can select a time range and view the daily read/write traffic (GB), daily index traffic - standard (GB), daily basic and advanced transfer traffic (GB), and daily standard storage volume (GB) of this period in tables or bar charts.
   • For a new log group or log stream, resource statistics will be collected in at least one hour.
   • Click the name of one of the top 100 log groups to query its log stream resource statistics.
   • Click to download the resource statistics of the log groups and streams. The downloaded files are in .CSV format.

6. Return to the Log Management page and click Details - Advanced in the upper right corner of the Statistics area. On the displayed page, view the resource usage details and top resources by usage.
   • On the Resource Usage Details tab page, view the raw log traffic, index traffic, and write traffic of log groups and streams. If the current version does not support a specific function, the LTS console will display no data in the related chart.
   • On the Top Usage tab page, view log groups and streams sorted by raw log traffic, index traffic, and write traffic. If the current version does not support a specific function, the LTS console will display no data in the related chart.

Alarm Statistics and Latest Alarms

In the lower part of Overview, you can view alarm statistics and latest alarms.

• The Alarms area displays the total number of LTS alarms and the number of alarms of each severity (Critical, Major, Minor, and Warning). You can view alarm statistics of the last 30 minutes, last 1 hour, last 6 hours, last 1 day, or last 1 week.
• The Latest Alarms area displays a maximum of three latest alarm rules in the last 30 minutes. To view more alarms or add alarm rules, click .
