APM System Metrics fields
editAPM System Metrics fields
editSystem status metrics, like CPU and memory usage, that are collected from the operating system.
system fields
editsystem
contains local system metrics.
cpu fields
editcpu
contains local CPU stats.
-
system.cpu.total.norm.pct
-
type: scaled_float
format: percent
The percentage of CPU time spent by the process since the last event. This value is normalized by the number of CPU cores and it ranges from 0 to 100%.
memory fields
editmemory
contains local memory stats.
-
system.memory.total
-
type: long
format: bytes
Total memory.
actual fields
editActual memory used and free.
-
system.memory.actual.free
-
type: long
format: bytes
Actual free memory in bytes. It is calculated based on the OS. On Linux it consists of the free memory plus caches and buffers. On OSX it is a sum of free memory and the inactive memory. On Windows, it is equal to
system.memory.free
.
process fields
editprocess
contains process metadata, CPU metrics, and memory metrics.
cpu fields
editcpu
contains local CPU stats.
-
system.process.cpu.total.norm.pct
-
type: scaled_float
format: percent
The percentage of CPU time spent by the process since the last event. This value is normalized by the number of CPU cores and it ranges from 0 to 100%.
memory fields
editMemory-specific statistics per process.
-
system.process.memory.size
-
type: long
format: bytes
The total virtual memory the process has.
-
system.process.memory.rss.bytes
-
type: long
format: bytes
The Resident Set Size. The amount of memory the process occupied in main memory (RAM).
