Basic Metrics: Node Exporter Metrics
This section describes the types, names, and meanings of metrics reported by Node Exporter to AOM.
Job |
Metric |
Description |
---|---|---|
node-exporter |
node_filesystem_size_bytes |
Consumed space of a file system |
node_filesystem_readonly |
Read-only file system |
|
node_filesystem_free_bytes |
Remaining space of a file system |
|
node_filesystem_avail_bytes |
File system space that is available for use |
|
node_cpu_seconds_total |
Seconds each CPU spent doing each type of work |
|
node_network_receive_bytes_total |
Total amount of received data |
|
node_network_receive_errs_total |
Cumulative number of errors encountered during reception |
|
node_network_transmit_bytes_total |
Total amount of transmitted data |
|
node_network_receive_packets_total |
Cumulative number of packets received |
|
node_network_transmit_drop_total |
Cumulative number of dropped packets during transmission |
|
node_network_transmit_errs_total |
Cumulative number of errors encountered during transmission |
|
node_network_up |
NIC status |
|
node_network_transmit_packets_total |
Cumulative number of packets transmitted |
|
node_network_receive_drop_total |
Cumulative number of packets dropped during reception |
|
go_gc_duration_seconds |
This value is obtained by calling the debug.ReadGCStats() function. When this function is called, the PauseQuantile field of the GCStats structure is set to 5. In this way, the function returns 5 GC pause time percentiles (the minimum percentile, 25%, 50%, 75%, and maximum percentile). Then, the Prometheus Go client creates a summary metric based on the returned GC pause time percentile, NumGC, and PauseTotal. |
|
node_load5 |
5-minute average CPU load |
|
node_filefd_allocated |
Allocated file descriptors |
|
node_exporter_build_info |
Node exporter build information |
|
node_disk_written_bytes_total |
Number of bytes that are written |
|
node_disk_writes_completed_total |
Number of writes completed |
|
node_disk_write_time_seconds_total |
Number of seconds spent by all writes |
|
node_nf_conntrack_entries |
Number of currently allocated flow entries for connection tracking |
|
node_nf_conntrack_entries_limit |
Maximum size of a connection tracking table |
|
node_processes_max_processes |
PID limit value |
|
node_processes_pids |
Number of PIDs |
|
node_sockstat_TCP_alloc |
Number of allocated TCP sockets |
|
node_sockstat_TCP_inuse |
Number of TCP sockets in use |
|
node_sockstat_TCP_tw |
Number of TCP sockets in the TIME_WAIT state |
|
node_timex_offset_seconds |
Time offset |
|
node_timex_sync_status |
Synchronization status of node clocks |
|
node_uname_info |
Labeled system information as provided by the uname system call |
|
node_vmstat_pgfault |
Number of page faults the system has made per second in /proc/vmstat |
|
node_vmstat_pgmajfault |
Number of major faults per second in /proc/vmstat |
|
node_vmstat_pgpgin |
Number of page in between main memory and block device in /proc/vmstat |
|
node_vmstat_pgpgout |
Number of page out between main memory and block device in /proc/vmstat |
|
node_disk_reads_completed_total |
Number of reads completed |
|
node_disk_read_time_seconds_total |
Number of seconds spent by all reads |
|
process_cpu_seconds_total |
The value is obtained based on the utime parameter (the number of ticks executed by the Go process in user mode) and the stime parameter (the number of ticks executed by the Go process in kernel mode, for example, during system invocation). Unit: jiffies, which measure the tick time between two system timer interruptions. process_cpu_seconds_total = (utime + stime)/USER_HZ Based on the preceding formula, you can obtain the total time (unit: seconds) for a process to run on the OS. |
|
node_disk_read_bytes_total |
Number of bytes that are read |
|
node_disk_io_time_weighted_seconds_total |
The weighted number of seconds spent doing I/Os |
|
node_disk_io_time_seconds_total |
Total seconds spent doing I/Os |
|
node_disk_io_now |
Number of I/Os in progress |
|
node_context_switches_total |
Number of context switches |
|
node_boot_time_seconds |
Node boot time |
|
process_resident_memory_bytes |
Resident set size (RSS), which is the memory actually used by a process. It includes the shared memory, but does not include the allocated but unused memory or swapped-out memory. |
|
node_intr_total |
Number of interruptions that occurred |
|
node_load1 |
1-minute average CPU load |
|
go_goroutines |
This value is obtained by calling runtime.NumGoroutine() and calculated based on the sched scheduler structure and global allglen variable. Fields in the sched structure may change concurrently. Therefore, the system checks whether the calculated value is less than 1. If the value is less than 1, the system returns 1. |
|
scrape_duration_seconds |
Time spent on collecting information about the scrape target |
|
node_load15 |
15-minute average CPU load |
|
scrape_samples_post_metric_relabeling |

Number of TCP connections that directly change from the LISTEN state to the SYN-RCVD state |
|
scrape_samples_scraped |
Number of samples scraped |
|
node_netstat_Tcp_CurrEstab |
Number of TCP connections in the ESTABLISHED or CLOSE-WAIT state |
|
scrape_series_added |
Number of series added to the scrape target |
|
node_netstat_Tcp_ActiveOpens |
Number of TCP connections that directly change from the CLOSED state to the SYN-SENT state |
|
node_memory_MemTotal_bytes |
Total memory of a node |
|
node_memory_MemFree_bytes |
Free memory of a node |
|
node_memory_MemAvailable_bytes |
Available memory of a node |
|
node_memory_Cached_bytes |
Memory for the node page cache |
|
up |
Scrape target status |
|
node_memory_Buffers_bytes |
Memory of the node buffer |
