When you use Prometheus Service of Application Real-Time Monitoring Service (ARMS), you are charged based on the number of reported data entries on billable metrics. The metrics are classified into two types: basic metrics and custom metrics. Custom metrics refer to non-basic metrics. Basic metrics are free of charge. You are charged for custom metrics starting from January 6, 2020.
The following tables describe the basic metrics of Kubernetes clusters that are supported by Prometheus Service.

The value indicates all allocated memory, including the memory that is allocated but not used, and the memory that is shared and swapped out. process_start_time_seconds The value is obtained based on the start_timeparameter. Thestart_timeparameter specifies the time when a process starts. Unit: jiffy. The data comes from the/proc/statdirectory. You can divide the value of thestart_timeparameter by USER_HZ to calculate the value, which is measured in seconds.go_memstats_next_gc_bytes The heap memory size during the next GC cycle. GC is used to guarantee that the value is no less than the value of the go_memstats_heap_alloc_bytesmetric.go_memstats_heap_objects The number of objects allocated on the heap. These objects change with GC and the allocation of new objects. process_resident_memory_bytes The RSS. The value indicates the actual memory used by processes, including the shared memory. The memory that is allocated but not used, or the memory that is swapped out is not included. process_open_fds The value is obtained by calculating the total number of files in the /proc/PID/fddirectory. It shows the total number of regular files, sockets, and pseudo-terminals opened by Go processes.process_max_fds The value is obtained by reading the value of the Max Open Filesrow in the/proc/{PID}/limitsfile. The value is a soft limit. The soft limit is the value that the kernel uses to limit the resources. The hard limit is the maximum value of the soft limit.go_memstats_other_sys_bytes The size of the memory used for other runtime allocations. go_gc_duration_seconds_count - go_memstats_heap_alloc_bytes The number of memory bytes allocated for heap objects, including not only all reachable heap objects, but also the unreachable objects that are not removed during GC. process_cpu_seconds_total The value is obtained based on the utimeparameter (the number of ticks executed by the Go process in user mode) and thestimeparameter (the number of ticks executed by the Go process in kernel mode or when the system is called. Unit of the parameters: jiffy, which measures the tick time between two system timer interruptions. The value of the process_cpu_seconds_total metric is the sum of utime and stime divided by USER_HZ.

You can call the rate()function to calculate the removal rate of heap objects. You can use thego_memstats_mallocs_total - go_memstats_frees_totalformula to calculate the number of surviving heap objects.go_threads The value is obtained by calling the runtime.CreateThreadProfile()function based on the global allm variable.go_memstats_mspan_sys_bytes The amount of memory allocated from the operating system for the mspan structure. go_memstats_buck_hash_sys_bytes The amount of memory occupied by the hash tables used for profiling. go_memstats_alloc_bytes_total The value of the metric increases as objects are allocated in the heap, but does not decrease when objects are removed. Similar to Prometheus counters, the rate()function can be called to query the memory consumption rate.go_memstats_heap_sys_bytes The number of memory bytes allocated for the heap from the operating system, including the virtual address space that is reserved but not used. go_memstats_mspan_inuse_bytes The amount of memory used by the mspan structure. go_memstats_alloc_bytes The number of memory bytes allocated for heap objects, The value is the same as the value of the go_memstats_heap_alloc_bytesmetric. The heap objects include not only all reachable heap objects, but also the unreachable objects that are not removed during GC.go_info The information about the Go version. The value is obtained by calling the runtime.Version()function.go_memstats_last_gc_time_seconds The timestamp when the last GC was completed. go_memstats_heap_inuse_bytes The number of bytes occupied by the spans in use. go_memstats_mcache_sys_bytes The amount of memory allocated from the operating system for the mcache structure. go_memstats_lookups_total A counter value that shows the number of dereferenced pointers. You can call the rate()function to calculate the dereferencing rate of pointers.go_memstats_mallocs_total A counter value that shows the number of allocated heap objects. You can call the rate()function to calculate the allocation rate of heap objects.go_gc_duration_seconds_sum - go_goroutines The value is obtained by calling the runtime.NumGoroutine()function based on the sched scheduler structure and the global allglen variable. All fields in the sched structure may concurrently change. Therefore, the system checks whether the value is less than 1. If the value is less than 1, 1 is returned.go_memstats_heap_idle_bytes The number of memory bytes occupied by idle spans. - The following table describes the job that collects data from persistent volumes (PVs) and the basic metrics that are collected.
