Link Layer stats

Combiner for link layer stats. It uses the results of the netstat -i parser and the ip -s link parser to determine the network stats of link layer. ip -s link is the preferred source of data and return object which can be used to access group_by_iface.

Examples

>>> type(nstat)
<class 'insights.combiners.netstat.NetworkStats'>
>>> stats = nstat.group_by_iface
>>> stats["lo"]
{'RX-OK': 98, 'TX-OK': 100, 'MTU': 65536, 'RX-ERR': 0, 'TX-DRP': 0, 'TX-ERR': 0, 'RX-DRP': 0, 'RX-OVR': 0, 'Flg': 'LRU'}
>>> stats["enp0s8"]
{'RX-OK': 6, 'TX-DRP': 0, 'TX-OK': 4, 'MTU': 1500, 'RX-ERR': 0, 'TX-ERR': 0, 'RX-DRP': 0, 'RX-OVR': 0, 'Flg': 'BMRU'}
>>> print nstat.data[0]['Iface']
enp0s8
>>> for dev_item in nstat.data:
>>>     print dev_item
{'RX-OK': '842447', 'TX-OVR': '0', 'Iface': 'bond1', 'TX-OK': '4233', 'MTU': '1500', 'Met': '0', 'RX-ERR': '0', 'TX-DRP': '0', 'TX-ERR': '0', 'RX-DRP': '0', 'RX-OVR': '0', 'Flg': 'BMmRU'}

class insights.combiners.netstat.NetworkStats(net_stats, ip_stats)

Bases: object

A combiner for working with both netstat -i and ip -s link That is if netstat -i gets deprecated then we can continue with ip -s link.

This interface closely follow interface Netstat_I it has following Attributes:

group_by_iface

This property returns network stats organised per interface in dict format.

Type:

dict

data

List of network stats as per devices.

Type:
