Question by Drew C. · Jun 02, 2017 at 07:42 PM · appmon 6.5 agent java diagnostics appmonsaas

How are Host Metrics Collected by Java Agent?

I was comparing the "Memory Usable" metric collected by JMX with the built-in "Memory Usable" metric collected by the Java Agent on a CentOS server and noticed discrepancies between the two:

When I ran the "free" command, I saw the following:

free

total used free shared buff/cache available

Mem: 15401136 730028 13714196 49436 956912 12840340

Swap: 0 0 0

How is the "Memory Usable" metric being calculated by the Java Agent? And will this discrepancy apply to all of the other host metrics?
