Configuring a Tracker

Scenario

You can configure the created management tracker to transfer traces recorded in CTS to OBS or LTS for long-term storage.

You can select whether to send recorded traces to an OBS bucket. You can also transfer the traces of multiple accounts to the same OBS bucket for centralized management.

There are three storage classes of OBS buckets, Standard, Infrequent Access, and Archive. You must use Standard OBS buckets for trace transfer because CTS needs to frequently access the OBS buckets.

After the tracker configuration is complete, CTS will immediately start recording operations under the new settings.

This section describes how to configure the management tracker.

Prerequisites

You have enabled CTS.

Procedure

1. Log in to the management console.
2. Click in the upper left corner to select the desired region and project.
3. Click in the upper left corner and choose > Cloud Trace Service. The CTS console is displayed.
4. Choose Tracker List in the left navigation pane.
5. Click Configure in the Operation column in the row of the management tracker.
6. On the Configure Transfer page, modify the transfer configurations of the tracker. For details, see Table 1.

   Table 1 Transfer parameters

   Parameter	Description
   Transfer to OBS	Select an existing OBS bucket or create one on this page and set File Prefix.
   OBS Bucket	Existing: Select an existing OBS bucket.
   Select Bucket	If you select New for OBS Bucket, enter an OBS bucket name. The OBS bucket name cannot be empty. It can contain 3 to 63 characters, including only lowercase letters, digits, hyphens (-), and periods (.). It cannot contain two consecutive periods (for example, my..bucket). A period (.) and a hyphen (-) cannot be adjacent to each other (for example, my-.bucket and my.-bucket). Do not use an IP address as a bucket name. If you select Existing for OBS Bucket, select an existing OBS bucket.
   Retention Period	For the management tracker, the retention period configured on the OBS console is used by default and cannot be changed.
   File Prefix	A prefix is used to mark a transferred trace file. Your specified prefix will be automatically added to the beginning of the name of a transferred file, helping you quickly filter files. Enter 0 to 64 characters. Only letters, digits, hyphens (-), underscores (_), and periods (.) are allowed.
   Transfer to LTS	When Transfer to LTS is enabled, traces are transferred to the log stream.
   Log Group	When Transfer to LTS is enabled, the default log group name CTS is set. When Transfer to LTS is disabled, no operation is required.

7. Click Next > Configure to complete the configuration of the tracker.

   You can then view the tracker details on the Tracker List page.

   

   Traces recorded by CTS are delivered periodically to the OBS bucket for storage. If you configure an OBS bucket for a tracker, traces generated during the current cycle (usually several minutes) will be delivered to the configured OBS bucket. For example, if the current cycle is from 12:00:00 to 12:05:00 and you configure an OBS bucket for a tracker at 12:02:00, traces received from 12:00:00 to 12:02:00 will also be delivered to the configured OBS bucket for storage at 12:05:00.
