Troubleshoot Problems with a Host System
You use the Troubleshooting tabs to identify the root cause of problems that are not resolved by alert
recommendations or simple analysis.
To further troubleshoot the symptoms of the capacity problems that are occurring on the cluster and host
system, and determine when those problems occurred, you use the Troubleshooting tabs to continue to
investigate the memory problem.
Prerequisites
Use the Analysis tabs to analyze your environment. See Analyze the State of Your Environment,” on
page 21.
Procedure
1 Click Environment > vSphere Hosts and Clusters > USA-Cluster.
2 Click the Troubleshooting tab and review the symptoms.
The Symptoms tab displays the symptoms that triggered on the selected cluster. You notice that several
critical symptoms exist.
n
Cluster Compute Resource Time Remaining with committed projects is critically low
n
Cluster Compute Resource Time Remaining is critically low
n
Capacity remaining is critically low
3 Analyze the critical symptoms.
a Hover your mouse over each critical symptom to identify the metric used.
b To view only the symptoms that aect the cluster, enter cluster in the quick lter text box.
When you hover over Cluster Compute Resource Time Remaining is critically low, the metric
Badge|Time Remaining with committed projects (%) appears. You notice that its value is less than
or equal to zero, which caused the capacity symptom to trigger and generate an alert on USA-
Cluster.
4 Click the Timeline tab to review the triggered symptoms, alerts, and events that occurred on USA-
Cluster over time, and identify when the problems occurred.
a On the toolbar, click Select Event Type.
b Click Date Controls and select Last 7 Days.
Several events appear in red.
c Hover your mouse over each event to view the details.
d To display the events that occurred on the cluster's data center, click Show Ancestor Events, and
select Datacenter.
Warning events for the data center appear in yellow.
e Hover your mouse over the warning events.
You notice that the density is starting to get low, and that a hard threshold violation occurred on
the data center late in the evening. The hard threshold violation shows that the Badge|Density
metric value was under the acceptable value of 25, and that the violation triggered with a value of
14.89.
f To view the aected child objects, click Show Descendant Events and select Host System.
