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  this knowledge article .

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 External Report attribute set .

Note

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.
