How does Reporter 9 calculate available memory?

<< Back to Knowledge Search



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.


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


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.
