How does Reporter 9 calculate available memory?

Solution

Overview

In Reporter 9, how is the declared available memory (capacity) determined?

Using the Windows Diagnostic utility winmsd provides a discrepancy between Total Physical Memory and the value Reporter declares as Memory Capacity.  What value is Reporter using?

The LINUX command ps aux | grep bcreport yields a percentage value for capacity that is smaller than that reported by Reporter.

Cause
Resolution

The Reporter Management Console provides two locations that declare how much memory perceived as available for use.

  • Log into Reporter with Admin user credentials.
  • Navigate to the Administration section.
  • Select General Settings > Reporter Settings <system settings > Alerts Settings.
  • The value reported here (Capacity) is the value Reporter declares as available memory.
  • Navigating to System Overview > Diagnostics also provides this same value.

NOTE 1: When you run the Microsoft winmsd application, the equivalent value is called Available Virtual Memory.  This is not the same value as Total Physical Memory.

NOTE 2: For both LINUX and Windows, Reporter only shows the capacity as a percentage of the virtual memory.

NOTE 3: The Linux ps aux | grep bcreport command reports a smaller percentage than Reporter because it only uses physical memory as its total value. The two examples below show the LINUX PS command reporting a memory capacity of 14975988 while Reporter indicates a total memory of 20.46 GB.

  • The command and its output looked like this:

[root@userX  Reporterserver]# ps aux | grep bcreport

USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND

root      3726  8.1 58.8 14975988 9597616 ?    Ssl  13:35   8:49 /DATA/Reporter9/bcreporter --service

[root@n1cr02 Reporter9]#

  • While the Reporter UI looked like this:

 

The same type of information is contained in the sysinfo file, which is provided by Reporter Diagnostics. The value of virtual memory is called Page File: Max Size. For example:

NOTE 2:  The above triggers are for general out-of-memory conditions that occur while the database is loaded; however, available memory is also checked before running reports. For details on how the required memory needed to run reports is calculated, see 000015704.
