Dashboards |
Dashboards |
A maximum of 500 dashboards can be created in a region. |
Graphs in a dashboard |
A maximum of 30 graphs can be added to a dashboard. |
|
Resources, threshold rules, components, or hosts in a graph |
|
|
Metrics |
Metric data |
Metric data can be stored in the database for up to 30 days. |
Total metrics |
Up to 400,000 for a single account. Up to 100,000 for a small specification. |
|
Metric items |
After resources (such as clusters, components, and hosts) are deleted, their metric items can be stored for up to 30 days. |
|
Dimensions |
A maximum of 30 dimensions can be configured for a metric. |
|
Metric query API |
A maximum of 20 metrics can be queried at a time. |
|
Statistical period |
The maximum statistical period is 1 hour. |
|
Data points returned for a single query |
A maximum of 1440 data points can be returned each time. |
|
Custom metrics |
Unlimited. |
|
Custom metrics reported |
A single request cannot exceed 40 KB. The timestamp of a reported metric cannot be 10 minutes later than the standard UTC time. In addition, out-of-order metrics are not received. That is, if a metric is reported at a certain time point, the metrics of earlier time points cannot be reported. |
|
Application metrics |
|
|
Resources consumed by the ICAgent |
When the ICAgent collects basic metrics, the resources consumed by the ICAgent are greatly affected by the number of containers and processes. On a VM without any services, the ICAgent consumes 30 MB memory and records 1% CPU usage. To ensure collection reliability, ensure that the number of containers running on a single node must be less than 1000. |
|
Logs |
Size of a log |
The maximum size of each log is 10 KB. If a log exceeds 10 KB, the ICAgent does not collect it. That is, the log will be discarded. |
Log traffic |
A maximum of 10 MB/s is supported for each tenant in a region. If the log traffic exceeds 10 MB/s, logs may be lost. |
|
Log files |
Text and binary log files can be collected. |
|
The ICAgent can collect a maximum of 20 log files from a volume mounting directory. |
||
The ICAgent can collect a maximum of 1000 standard container output log files. These files must be in JSON format. |
||
Resources consumed during log file collection |
The resources consumed during log file collection are closely related to the log volume, number of files, network bandwidth, and backend service processing capability. |
|
Log loss |
The collector uses multiple mechanisms to ensure log collection reliability and prevent data loss. However, logs may be lost in the following scenarios:
|
|
Log loss |
When a single log line exceeds 10,240 bytes, the line will be discarded. |
|
Log repetition |
When the ICAgent is restarted, identical data may be collected around the restart time. |
|
Alarms |
Alarms |
You can query the alarms generated in the last 31 days. |
Events |
You can query the events generated in the last 31 days. |
|
- |
Application discovery rules |
You can create a maximum of 100 application discovery rules. |

500 vCPUs, about 100,000 metrics |
1000 vCPUs, about 200,000 metrics |
2500 vCPUs, about 600,000 metrics |
When the total number of metrics exceeds the limit, system metrics can still be reported but custom metrics cannot. Reduce the number of custom metrics. |
If the total number of metrics exceeds the limit, expand the AOM scale or contact O&M personnel. AOM supports a maximum of 2500 vCPUs (about 600,000 metrics). |
