The Server Health report
TrueSight Smart Reporting includes an out-of-the-box Server Health report. This report displays the health of a server for a specified period.
To view all attributes that are updated in TrueSight Operations Management 11.3.04, apply the TrueSight Smart Reporting hotfix 11.3.01.000.14. Follow the instructions given in .
In this report, a bar graph displays the percent of the time that the server was available during the selected time range. The line graphs display hourly summarized values for each server's attributes during the selected time range. This data includes the average and maximum usage for CPU Utilization, Memory Used, Disk Space Used, and Network Utilization.
The following image displays the Server Health report.
Availability graph details
The Availability graph shows the percentage of time for the server's availability or unavailability. The percentage is calculated based on the following rules:
- The Availability graph results are based on PING KM configured for the device
- The Availability attribute returns a 0 or 1 value per polling cycle.
For most operating systems, 0 means unavailable, and 1 means available.
For an Azure operating system, the State attribute is used to determine availability. A value of 0 means unavailable and 1 means available.
- To calculate availability, the system uses hourly summarized data that is based on the following formula:
Availability = 100 - (Sum (availability values in an hour) / Count (availability values in an hour) * 100)
- Availability results can be incorrect if some data points are missing in the report engine during a particular hour.
- The No Data portion (white color) of the Availability bar graph means that there was no data for PING KM in the report engine or Ping KM is not configured for that device.
Each bar in the Availability graph represents an hour. If the device was not working during a specific hour for 30 minutes, the bar for that hour half green and half in red.
Server Health report monitor types and attributes
The following table lists the monitor type and attributes in the Server Health report, based on operating systems. These attributes must be added in the .
|Operating system||Monitor/Attribute||CPU||Memory||Disk space||Network||Availability|
|Windows||Monitor||Processor||Windows Memory Performance||Health At A Glance||Network Interface||Ping Device|
|Attribute||Processor Time||Memory Used||Highest Percentage of Disk Used||Network Utilization||Availability|
|VMWare||Monitor||VMWare CPU Container||VMWare Memory||VMware VM Disk Container||VMware Network||Ping Device|
|Attribute||Total CPU Utilization||Memory Used by Host or Virtual Machine||Total Provisioned Space Utilization||Total Network Data Received and Transmitted||Availability|
|Attribute||% CPU Utilization||Memory Used||% Filesystem Space Used||Percentage Bandwidth Utilization||Availability|
|Linux||Monitor||CPU||Memory||File System||Network||Ping Device|
|Attribute||Utilization||Used Memory||Filesystem Space Utilization||Percentage Bandwidth Utilization||Availability|
|Citrix||Monitor||Citrix Xen Host CPU Container||Citrix Xen Host Memory||Citrix Xen Storage Repository||Citrix Xen Physical Network||Ping Device|
|Attribute||Aggregate CPU Utilization of Xen Host||Used Memory||Storage Space Used||Network Utilization||Availability|
|AWS||Monitor||EC2 CPU||-||-||-||Ping Device|
|Attribute||Utilization||Used Memory||Utilization||Bandwidth Utilization||Availability|
|Azure (Windows)||Monitor||Azure Virtual Machine Processor||-||-||-||Azure Virtual Machine|
|Azure (Linux)||Monitor||Azure Virtual Machine Processor||Azure Virtual Machine Memory||-||-||Azure Virtual Machine|
|Attribute||Processor Time||Used Memory||-||-||State|
A PING Knowledge Module must be configured for all of the devices that you need to measure for availability. For Azure operating systems, measure availability with an Azure virtual machine monitor type "state" attribute.
