Host group

View host group

After creating a host group, you can go to Host group detail page to view its information, including basic information, the heartbeat status of all machines in the group, the associated collection configuration, and LogCollector management.

Steps

Select the region where torch log service is located from the top navigation bar.

On the left navigation bar, select Resource management > Host group.

On the Host group management page, click the name of the specified host group.

The host group details page includes the host group information section, heartbeat status tab, associated collection configuration tab, and LogCollector management tab.

View host group information

The Host group information section displays the basic details of the current host group, including the host group ID, type, and creation time.

Display item	Description
Host group ID	ID of the current host group.
Host group type	The host group type refers to either IP address type or host identification type.
Host identification	Host identification that is configured for the host group. Displayed only when host group type is set to host identification.
Create on	The creation time of host group.
Modified on	Last modification time for host group configuration.
IAM Project	The IAM project to which the host group belongs.

View heartbeat status

In Heartbeat status tab, you can view lists of all hosts, abnormal hosts, or normal hosts.

The list displays the status and LogCollector versions for each host. In the upper right corner of this section, you can enter IP address in the search box to view details for a specific IP address.

Display item	Description
IP	The IP address of the servers in the host group. By default, the first network interface's IP address is used. You can also specify another IP address during initialization via the ip parameter. For more details, see Install LogCollector (host machine).
Status	LogCollector connection status with the server and TLS. Normal: LogCollector is successfully installed on this host; the connection between LogCollector and TLS is normal. Notice When host group type is host identification, only servers with Normal heartbeat status are displayed (i.e., host that is configured with host identification and maintains normal communication with the server). If the number of servers with configured Host identification does not match the number shown in the host group, LogCollector heartbeat failure many exist in some servers. For troubleshooting, see problem phenomenon. Abnormal: LogCollector connection on this machine is abnormal. We recommend that you see Machine group heartbeat problem troubleshooting (host)for troubleshooting. If the abnormal situation does not affect your business and too many records exist, click Clear abnormal hosts to remove all abnormal heartbeat records in one step.
LogCollector version	The installed LogCollector version on the corresponding server.

View associated collection configurations

The Associated collection configurations tab shows the list of associated collection configurations. The list displays the configuration name, ID, and log type.

Actions	Description
View collection configuration	Click the specified collection configuration name to enter the details page. Information like basic information, collection rules, and host group information are displayed. You can edit collection rules, associate host groups, and delete or pause the collection configuration on this page.
Associate collection configuration	First click Collection rule association. Then select the collection configuration to associate and click OK.
Unbind collection configuration	Locate the specified associated collection configuration, click Unbind host group in Actions column. Confirm the information, and then click OK. After the host is unbound, servers in the host group will stop collecting logs according to this collection rule. For detailed instructions, see LogCollector collection configuration management.

Manage LogCollector

In LogCollector management tab, you can manually upgrade or downgrade LogCollector, enable automatic upgrades, and restart host groups in batches.

Notice

LogCollector V2.3.1 and later version support the LogCollector management tab**.**

Only LogCollector that is deployed on physical machine supports upgrading and downgrading.

Actions	Description
Manual upgrade or downgrade	Shows whether the current LogCollector can be manually upgraded or downgraded in the console. This feature is supported only by LogCollector version V2.3.1 and later. For manual upgrade or downgrade of other versions, see Upgrade LogCollector (host machine), Upgrade LogCollector (Kubernetes cluster). If the upgrade and downgrade button is greyed out: manual upgrade and downgrade are currently not supported. If the upgrade and downgrade button is available: manual upgrade and downgrade are currently supported. Click Upgrade and downgrade and select the LogCollector version that you want to upgrade or downgrade. Then click OK to manually complete the LogCollector version upgrade or downgrade. LogCollector stops collecting data during the upgrade or downgrade period. We suggest that you schedule the upgrade or downgrade time appropriately.
Auto upgrade	Shows whether the automatic upgrade feature for LogCollector is enabled. Enabled: Automatic upgrade is enabled, and the upgrade time is displayed. To change the automatic upgrade time or disable the automatic upgrade feature, click Modify. Disable: The automatic upgrade feature is not enabled. To enable the automatic upgrade feature and set the upgrade time, click Modify.
Restart host groups in bulk	Show whether host groups can be restarted in batches. If Restart button is disabled: Batch restart host group is not supported for now. If Restart button is available: Batch restart host group is supported. To batch restart host groups, click Restart, and confirm the prompts before you click OK. Notice Do not rename or delete log files during the restart process. Otherwise, some logs may fail to be collected.

For details on startup parameters, see Configure LogCollector startup parameters. If no configuration item is present, click Add configuration, and then enter the configuration details before you click OK. The system will deliver the configuration later.
