Guance's Status Page is based on the above data processing process to determine the service status in the data processing and data storage processes, as shown in the table below:
| Judgment Item | Judgment Condition | Service Status | Example Explanation |
|---|---|---|---|
| Data Push Failure Rate | Greater than 90% | Exception | When the failure rate of pushing log data from Kodo to the message queue is greater than 90%, the status of the log service is considered as exceptional. |
| Data Storage Failure Rate | Greater than 90% | Exception | When the failure rate of writing log data from Kodo-x to the database is greater than 90%, the status of the log service is considered as exceptional. |
| Message Subscription Delay P99 | Greater than 5 minutes | Delay | When the P99 delay of sending message queue data to Kodo-x exceeds 5 minutes in the collection of application performance data, the status of the APM service is considered as delayed. |
