[dpdk-users] memory tracker in PMD level

[dpdk-users] memory tracker in PMD level

[SAKTHIVEL ANAND S]

Hi

How can we track the packet drops in the PMD level, when receiving rings is
full or by some other means.

Lets assume my processing speed is less than receiving line rate so PMD
rings are over run and incoming packets are getting dropped. how should i
track this issue(status of mbufs and dropping packets counts in PMD). Is
there any APIs or any tool available? is libtrace will help here?

any help would be much appreciated.

In most/all of the PMD drivers the stats will give you dropped packets at the wire.

I sent this information offline, but sending here for others:

Please have a look at the Docs in the area of rte_eth_stats_get() https://readthedocs.org/projects/dpdk/
