Memory settings
Hi all,
in my new AppMon 7.1 installation the Sizing tab says we've 62,8Gb available:
and if I select the option Large with 64GB the server doesn't start because they doesn't have enough memory,
But If i check the memory in the server I see 64Gb:
Why? I need to configure the sizing Large with 64Gb....

Hi Josep Mari,
technically, one GB would be 1024 MB. In your free -m output, you can see that you have 64257 MB which divided by 1024 gives 62.75 GB as stated in our config dialog.
If you call free -g, you'll see that this value is correct. Maybe you could ask the hardware / vmware admins to get you some more megabytes RAM (64GB would mean 65536 MB). Best regards,
Peter
Hi Peter,
with top and meminfo I see 65799 MB:
maybe because these commnads include memory mapped by hardware devices?
so, to start dynatrace with one large64 option we need the 65536 MB displayed by free -m?
Thanks,
Hi Josep,
these are all actually the same value:
65799720 kB = 64257.54 MB = 62.75 GB
whereas 64G would give
64 GB = 65536 MB = 67108864 kB
We use the OperatingSystemMXBean to query the total system memory which is pretty likely to return this same value. Let me know if you need more details, cheers,
Peter
