The quickest way to quickly view the usage of a host is as follows:
650) This. width = 650; "style =" width: 741px; Height: 461px; "Title =" 1.png" alt = "wkiol1ph2fpsi_kpaak8qmbs7g8117.jpg" src = "http://s3.51cto.com/wyfs02/M00/3E/D6/wKioL1PH2FPSi_KpAAK8qMBs7g8117.jpg" width = "1157" Height = "470"/>
The following describes how to monitor a host

An alarm can be generated through a pre-defined trigger to generate a behavior, such as running a script in a mail.

Alarms are also divided into layers

The different scheduled tasks of the seats created by the alarm will change. Next, we will create an alarm. This instance is mainly used to monitor the VM snapshot space. The main steps are as follows:
650) This. width = 650; "style =" width: 747px; Height: 544px; "Title =" 9.png" alt = "wKioL1PH6wDRc6-hAAOtRchQgXs897.jpg" src = "http://s3.51cto.com/wyfs02/M01/3E/DD/wKioL1PH6wDRc6-hAAOtRchQgXs897.jpg" width = "718" Height = "501"/>
650) This. width = 650; "style =" width: 741px; Height: 532px; "Title =" 12.png" alt = "wkiol1ph7wmgwgmpaakl7dwyu_8316.jpg" src = "http://s3.51cto.com/wyfs02/M02/3E/DE/wKioL1PH7WmgWgmpAAKL7DWyU_8369.jpg" width = "512" Height = "519"/>
You can select the monitoring content above. Obviously, I am monitoring the condition status and specific events of the virtual machine. This refers to a value, such as the CPU usage, memory usage, and so on. The second one is indicates an event. For example, if the VM is shut down and the power is down, the network disk is gone.
Here we add an alert to the data center
650) This. width = 650; "style =" width: 744px; Height: 703px; "Title =" 11.png" alt = "wkiol1ph7d2b9uhlaaobb67urpk098.jpg" src = "http://s3.51cto.com/wyfs02/M01/3E/DE/wKioL1PH7D2B9UHLAAOBb67URPk098.jpg" width = "1001" Height = "679"/>
650) This. width = 650; "style =" width: 744px; Height: 549px; "Title =" 16.png" alt = "wKioL1PH72-C_xWuAAMBsHVv-H0701.jpg" src = "http://s3.51cto.com/wyfs02/M00/3E/DF/wKioL1PH72-C_xWuAAMBsHVv-H0701.jpg" width = "513" Height = "509"/>
Add a condition in the trigger. This is an alarm that is greater than 20g and higher than 30g.
650) This. width = 650; "style =" width: 748px; Height: 528px; "Title =" 16.png" alt = "wkiol1ph8w6dyyocaaltlbigg20473.jpg" src = "http://s3.51cto.com/wyfs02/M02/3E/E1/wKioL1PH8w6DYyOcAALtLBigg20473.jpg" width = "509" Height = "504"/>
What does range mean?
650) This. width = 650; "style =" width: 742px; Height: 579px; "Title =" 18.png" alt = "wkiol1ph88mh38zta?fa_a5g438.jpg" src = "http://s3.51cto.com/wyfs02/M00/3E/E1/wKioL1PH88mh38zTAAPPSFa_a5g438.jpg" width = "510" Height = "553"/>
This setting is to collect more than 75% alarms every 5 minutes. If the range of the above image is set to 0 that exceeds or is lower than the limit, it will keep sending alarms. I keep setting it to 5. when the number exceeds 80, you told me that 75 has already been reported to the police.
Repeat the triggered warning. What I wrote above is 5, which means a warning is triggered every 5 minutes.
650) This. width = 650; "style =" width: 741px; Height: 555px; "Title =" 11.png" alt = "wKioL1PH-PyzpG2FAAPDiyg6bvI838.jpg" src = "http://s3.51cto.com/wyfs02/M02/3E/E3/wKioL1PH-PyzpG2FAAPDiyg6bvI838.jpg" width = "510" Height = "532"/>
This allows you to perform operations when certain conditions are met.
650) This. width = 650; "Title =" 21.png" alt = "wKiom1PH_GrwRg0rAAH_gavLY-8139.jpg" src = "http://s3.51cto.com/wyfs02/M00/3E/E4/wKiom1PH_GrwRg0rAAH_gavLY-8139.jpg"/>
No, I did not generate a snapshot result alert on 2003. How can I solve these warnings? Delete the snapshot and the warning disappears.

You can click confirm warning or reset the warning to green. Note that only specific monitoring conditions will appear.
Next let's take a look at the performance panel

The cluster is to put two machines together for details.
