Host Monitoring

Precautions

• A maximum of five tags can be added to a host, and each tag must be unique.
• The same tag can be added to different hosts.

Procedure

1. Log in to the AOM 2.0 console.
2. In the navigation pane, choose Infrastructure Monitoring > Host Monitoring.
   • Set filter criteria (such as the running status, host type, host name, and IP address) above the host list.
   • You can enable or disable Hide master host. By default, this option is enabled.
   • Click next to Hide master host to synchronize host information.
   • In the upper right corner of the page, set filter criteria.
     • Set a time range to view the hosts reported. There are two methods to set a time range:
     • Method 1: Use the predefined time label, such as Last 30 minutes, Last hour, Last 6 hours, Last day, or Last week. Select one as required.
     • Method 2: Specify the start time and end time (max. 30 days).
     • Set the interval for refreshing information. Click and select a value from the drop-down list as required, such as Refresh manually, 30 seconds auto refresh, 1 minute auto refresh, or 5 minutes auto refresh.
     • Click in the upper right corner and select or deselect Tags.

3. Perform the following operations as required:
   • Adding an alias

     If a host name is too complex to identify, you can add an alias, which makes it easy to identify a host as required.

     In the host list, click in the Operation column of the target host, enter an alias, and click OK. The added alias can be modified but cannot be deleted.

   • Adding a tag

     Tags are identifiers of hosts. You can manage hosts using tags. After a tag is added, you can quickly identify and select a host.

     In the host list, click in the Operation column of the target host. In the displayed dialog box, enter a tag key and value, and click and OK.

   • Synchronizing host data

     In the host list, locate the target host and click in the Operation column to synchronize host information.

4. Set filter criteria to search for the desired host.
   

   Hosts cannot be searched by alias.

5. Click a host name. On the displayed host details page, you can view the running status and ID of the host.
