The dpdk-procinfo application is a Data Plane Development Kit (DPDK) application that runs as a DPDK secondary process and is capable of retrieving port statistics, resetting port statistics, printing DPDK memory information and displaying debug information for port. This application extends the original functionality that was supported by dump_cfg.
The application has a number of command line options:
./$(RTE_TARGET)/app/dpdk-procinfo -- -m | [-p PORTMASK] [--stats | --xstats |
--stats-reset | --xstats-reset] [ --show-port | --show-tm | --show-crypto |
--show-ring[=name] | --show-mempool[=name] | --iter-mempool=name ]
-p PORTMASK: Hexadecimal bitmask of ports to configure.
–stats The stats parameter controls the printing of generic port statistics. If no port mask is specified stats are printed for all DPDK ports.
–xstats The xstats parameter controls the printing of extended port statistics. If no port mask is specified xstats are printed for all DPDK ports.
–stats-reset The stats-reset parameter controls the resetting of generic port statistics. If no port mask is specified, the generic stats are reset for all DPDK ports.
–xstats-reset The xstats-reset parameter controls the resetting of extended port statistics. If no port mask is specified xstats are reset for all DPDK ports.
-m: Print DPDK memory information.
–show-port The show-port parameter displays port level various configuration information associated to RX port queue pair.
–show-tm The show-tm parameter displays per port traffic manager settings, current configurations and statistics.
–show-crypto The show-crypto parameter displays available cryptodev configurations, settings and stats per node.
–show-ring[=name] The show-ring parameter display current allocation of all ring with debug information. Specifying the name allows to display details for specific ring. For invalid or no ring name, whole list is dump.
–show-mempool[=name] The show-mempool parameter display current allocation of all mempool debug information. Specifying the name allows to display details for specific mempool. For invalid or no mempool name, whole list is dump.
–iter-mempool=name The iter-mempool parameter iterates and displays mempool elements specified by name. For invalid or no mempool name no elements are displayed.
