In the practice of operation and maintenance monitoring, since different operation and maintenance personnel may pay attention to different monitoring indicators, Lewei Monitoring will open all ports by default when monitoring network devices, covering as many monitoring indicators as possible to avoid missing important indicators . However, this will bring new problems. In some operation and maintenance scenarios, some "irrelevant" ports will frequently generate "UP/DOWN" alarms, resulting in failure to achieve the expected alarm effect.
Based on the different demands of different users for monitoring indicators, between large and comprehensive monitoring indicators and few and precise monitoring indicators, Lewei gives users the former by default, and users can remove unnecessary indicators from all monitoring indicators.
This article will introduce how Levi Monitor disables all the ports of network devices, and the operation and maintenance personnel can open and monitor the core ports according to actual needs during subsequent use. The following are the specific steps:
1. Find the template that needs to be adjusted under [Acquisition Manager]-[Template Management]. The following template is an example: 2.
Click on this template and click the "Full Clone" button
3. Need to adjust the [Template Name] and [Visible Name] ] (the name of the original template cannot be exactly the same), click the "Add" button 
4. The new template has been generated, and the new template needs to be migrated. Please refer to Template Migration-Object Migration (lwops.cn)
5. Click [Auto Discovery] of the new template
Click the prototype of the monitoring item named "Port Table UP" ("Port Table DOWN" also needs to perform the same steps),
select all monitoring items, and click the [Batch Update] button ("Port Table DOWN" also needs to perform the same steps)
Check [Enable New], click [No], and then click the [Update] button ("Port Table DOWN" also needs to perform the same steps) the effect is shown in the figure below: 6. Click the [Host] of the 
original 
template
Check all the hosts under the original template, click [Batch Update],
check the [Template Link], click the [Replace] button, then select the newly cloned template, check [Clear when there is no link], and finally click the [Update] button That's it
7. The hosts in the original template have been linked to the new template. 
8. The final effect is shown in the figure below. All ports have been disabled by default, and subsequent operation and maintenance personnel can open the ports they care about.
