Monitoring Your Hosts

This chapter describes how to monitor hosts using workflows that start in the Hosts dashboard. By following these workflows, you can view the performance of all monitored hosts or drill down on a single host.

Use the Hosts dashboard to monitor for problems in your environment if you are responsible for the availability of a set of hosts and prefer to think in terms of systems. The Hosts dashboard provides the best high-level summary of host state and performance, including alarms, CPU, memory, disk, network utilization, if a host is being monitored, and impacted services.

Drill down from this dashboard to different dashboards and views that provide more detail about your hosts. You can also use this dashboard to see if a host’s state has an impact on services and view the health history of each host.

Selecting a set of hosts to monitor

The Hosts dashboard is useful for monitoring environments with a large number of hosts, since you can choose to show only a subset of these hosts or display all hosts.

In many cases, you need to focus on a subset of these hosts. There are different ways to do this in the Hosts dashboard:

If you need to see data for all hosts in your environment, you can:

Select All Hosts from the Filter By Activity area and leave the default setting All Hosts in the menu underneath this area.

Identifying the types of hosts you are monitoring

The icons in the Type column allow you to see at a glance what kind of hosts you are monitoring: physical hosts are identified by the icon , VMware images by the icon , and ESX servers by the icon . Each icon displays the state embedded on top. For example, a physical host in a normal state has the following icon .

Monitoring the state of hosts

Now that you have chosen the group of hosts you want to monitor, refer to the icons in the first column in the table to see the state of these hosts at a glance. Each state indicator shows the host’s aggregate alarm state (excluding the state of agents on that host).

Investigate a host’s alarms to get more details about the problems contributing to its non-normal state. In the row for the host, click the icon that represents warning, critical, or fatal alarms to display an alarm list filtered to show only the warning, critical, or fatal alarms for that host. See Viewing, Acknowledging, and Clearing Alarms for information about working with alarms.
