+
+## Overview
+
+`/proc/net/softnet_stat` provides statistics that relate to the handling of network packets by softirq.
+
+It provides information about:
+
+- Total number of processed packets (`processed`).
+- Times ksoftirq ran out of quota (`dropped`).
+- Times net_rx_action was rescheduled.
+- Number of times processed all lists before quota.
+- Number of times did not process all lists due to quota.
+- Number of times net_rx_action was rescheduled for GRO (Generic Receive Offload) cells.
+- Number of times GRO cells were processed.
+
+Monitoring the /proc/net/softnet_stat file can be useful for:
+
+- **Network performance monitoring**: By tracking the total number of processed packets and how many packets
+  were dropped, you can gain insights into your system's network performance.
+
+- **Troubleshooting**: If you're experiencing network-related issues, this collector can provide valuable clues.
+  For instance, a high number of dropped packets may indicate a network problem.
+
+- **Capacity planning**: If your system is consistently processing near its maximum capacity of network
+  packets, it might be time to consider upgrading your network infrastructure.
+
+
+
+
+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 Softnet Statistics instance
+
+
+
+This scope has no labels.
+
+Metrics:
+
+| Metric | Dimensions | Unit |
+|:------|:----------|:----|
+| system.softnet_stat | processed, dropped, squeezed, received_rps, flow_limit_count | events/s |
+
+### Per cpu core
+
+
+
+This scope has no labels.
+
+Metrics:
+
+| Metric | Dimensions | Unit |
+|:------|:----------|:----|
+| cpu.softnet_stat | processed, dropped, squeezed, received_rps, flow_limit_count | events/s |
+
+
+
+## Alerts
+
+
+The following alerts are available:
+
+| Alert name  | On metric | Description |
+|:------------|:----------|:------------|
+| [ 1min_netdev_backlog_exceeded ](https://github.com/netdata/netdata/blob/master/health/health.d/softnet.conf) | system.softnet_stat | average number of dropped packets in the last minute due to exceeded net.core.netdev_max_backlog |
+| [ 1min_netdev_budget_ran_outs ](https://github.com/netdata/netdata/blob/master/health/health.d/softnet.conf) | system.softnet_stat | average number of times ksoftirq ran out of sysctl net.core.netdev_budget or net.core.netdev_budget_usecs with work remaining over the last minute (this can be a cause for dropped packets) |
+
