Notes and Constraints

There are fixed quotas on the number of trackers and key event notifications in CTS.

**Table 1** CTS constraints
Item	Constraints
Maximum number of trackers that can be created by a single Huawei Cloud account	Management tracker: 1 Data trackers: 100
Maximum number of key event notifications that can be configured by a single Huawei Cloud cloud account	100
Maximum number of OBS buckets that can be configured for a tracker	1
Time from when an operation is performed to when the operation data can be queried on the console	Management traces: 1 minute Data traces: 5 minutes
Time from when a member quits or is removed from an organization to when the organization tracker is withdrawn.	5 minutes
Time period in which traces can be queried on the console NOTE: By default, CTS only records traces generated in the last 7 days for each Huawei Cloud account. To store races generated 7 days ago, you need to transfer them.	7 days
Organization tracker	CTS offers organization trackers to implement multi-account management of Organizations. This capability relies on APIs of Organizations. Users without the enterprise project management function enabled can use this capability as long as they have the CTS permissions. However, users with enterprise project management function enabled must also be granted certain IAM permissions to use this capability.
For global services, you must configure trackers and key event notifications on the CTS console in the central region (CN-Hong Kong). This configuration enables functions of reporting traces to CTS, transferring traces to OBS or LTS, and sending key event notifications. The preceding functions will not take effect if you perform the configuration on the CTS console in any region outside the central region.
