Metrics of glb-director-xdp

[jstangroome]

We've been using the DPDK glb-director but had issues with driver support, so we're trialling using the XDP implementation instead and first impressions are excellent.

However, the DPDK version had dpdk-procinfo and statsd exporting from the glb-director process for understanding packets and bytes received and transmitted.

It seems that we can get some semblence of XDP network throughput statistics via ethtool -S $interface but it is again driver-specific and doesn't give XDP-only traffic metrics. The xdp project acknowledges that metrics for XDP are inconsistent at this time, and suggests that each XDP program does it's own accounting, one example of this is given here.

Is there already a source of traffic data for glb-director-xdp or would custom solution per the above example be necessary? Is metrics support planned or would it be considered?

We're definitely planning on adding direct metrics similar to the statsd ones from the DPDK version in the coming weeks as we look to get to feature parity on the XDP version. 👍 👍
