nstat
nstat shows network statistics and counters.Users of the command-line are typically aware of the netstat command. The package that netstat belongs to is getting deprecated and slowly replaced with tools like ip. This is also where nstat comes in, a more modern approach to pulling in data from the kernel. Another benefit is that it can retrieve more information than netstat. This is due to the static list of metrics that netstat looks for, while nstat will parse output files from /proc.
Sources that nstat uses to retrieve its information include the following files.
- /proc/net/netstat
- /proc/net/snmp
- /proc/net/snmp6
- /proc/net/sctp/snmp
- /proc/uptime
