APM System Metrics fieldsedit
System status metrics, like CPU and memory usage, that are collected from the operating system.
system fieldsedit
system contains local system metrics.
cpu fieldsedit
cpu 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 fieldsedit
memory contains local memory stats.
-
system.memory.total -
type: long
format: bytes
Total memory.
actual fieldsedit
Actual 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 fieldsedit
process contains process metadata, CPU metrics, and memory metrics.
cpu fieldsedit
cpu 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 fieldsedit
Memory-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).
