What Trigger Conditions Can Be Set for Log Alarms?

When the retrieval results of the target log units meet the trigger conditions, an alarm notification is triggered. Multiple trigger conditions can be set at the same time. Currently, two types of trigger conditions are supported:

Results matched: When the retrieval results contain log data, an alarm is triggered.
Specific pieces of data: When the log data in the retrieval results meets certain conditions, an alarm is triggered and conditional expressions can be set.

What Is the Check Frequency of Log Alarms?

You can customize the check frequency. Currently, fixed frequency and fixed time are supported:

Fixed frequency: executes a monitoring task at a fixed interval. The interval can be set in minutes, hours, and days.
Fixed time: executes a monitoring task at a fixed time point every day.

How to Set an Alarm Based on a Keyword?

After you collect logs into Cloud Log Service, you can use the log alarm function to implement alarms based on log keywords. For details, see Best Practice-Keyword-triggered Alarms.

Why Only One Trigger Condition Works Since I Have Set Multiple Conditions?

The alarm service will match the triggering conditions one by one. If you set multiple trigger conditions, then when the query results match the first trigger condition, subsequent trigger conditions will not be matched. It is recommended that you configure alarms from the highest severity level to the lowest.
