Network statistics

Plugin: proc.plugin Module: /proc/net/netstat

Overview

This integration provides metrics from the netstat, snmp and snmp6 modules.

This collector is supported on all platforms.

This collector supports collecting metrics from multiple instances of this integration, including remote instances.

Default Behavior

Auto-Detection

This integration doesn't support auto-detection.

Limits

The default configuration for this integration does not impose any limits on data collection.

Performance Impact

The default configuration for this integration is not expected to impose a significant performance impact on the system.

Metrics

Metrics grouped by scope.

The scope defines the instance that the metric belongs to. An instance is uniquely identified by a set of labels.

Per Network statistics instance

This scope has no labels.

Alerts

The following alerts are available:

Alert name	On metric	Description
1m_tcp_syn_queue_drops	ip.tcp_syn_queue	average number of SYN requests was dropped due to the full TCP SYN queue over the last minute (SYN cookies were not enabled)
1m_tcp_syn_queue_cookies	ip.tcp_syn_queue	average number of sent SYN cookies due to the full TCP SYN queue over the last minute
1m_tcp_accept_queue_overflows	ip.tcp_accept_queue	average number of overflows in the TCP accept queue over the last minute
1m_tcp_accept_queue_drops	ip.tcp_accept_queue	average number of dropped packets in the TCP accept queue over the last minute
tcp_connections	ip.tcpsock	TCP connections utilization
1m_ip_tcp_resets_sent	ip.tcphandshake	average number of sent TCP RESETS over the last minute
10s_ip_tcp_resets_sent	ip.tcphandshake	average number of sent TCP RESETS over the last 10 seconds. This can indicate a port scan, or that a service running on this host has crashed. Netdata will not send a clear notification for this alarm.
1m_ip_tcp_resets_received	ip.tcphandshake	average number of received TCP RESETS over the last minute
10s_ip_tcp_resets_received	ip.tcphandshake	average number of received TCP RESETS over the last 10 seconds. This can be an indication that a service this host needs has crashed. Netdata will not send a clear notification for this alarm.
1m_ipv4_udp_receive_buffer_errors	ipv4.udperrors	average number of UDP receive buffer errors over the last minute
1m_ipv4_udp_send_buffer_errors	ipv4.udperrors	average number of UDP send buffer errors over the last minute
