APM System Metrics fieldsedit
System status metrics, like CPU and memory usage, that are collected from the operating system.
systemedit
system contains local system metrics.
cpuedit
cpu contains local CPU stats.
-
system.cpu.total.norm.pct -
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%.
type: scaled_float
format: percent
memoryedit
memory contains local memory stats.
-
system.memory.total -
Total memory.
type: long
format: bytes
actualedit
Actual memory used and free.
-
system.memory.actual.free -
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.type: long
format: bytes
processedit
process contains process metadata, CPU metrics, and memory metrics.
cpuedit
cpu contains local CPU stats.
-
system.process.cpu.total.norm.pct -
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%.
type: scaled_float
format: percent
memoryedit
Memory-specific statistics per process.
-
system.process.memory.size -
The total virtual memory the process has.
type: long
format: bytes
-
system.process.memory.rss.bytes -
The Resident Set Size. The amount of memory the process occupied in main memory (RAM).
type: long
format: bytes
