The motivation for this tool is to help identify demanding flow content.
This series of patches provide:
- implementation in utilitites directory
- changes to debian distribution
- changes to rpm based distribution.
Every second ovs-dpctl dump-flow content is aggregated and presented by
decreasing packet count. Several flow concepts are extracted and
presented individually:
- MAC address pairs
- IPv4 and IPv6 address pairs
- eth types
- ip protocol
- destination port
- in port
Testing included:
- confirmed parser handles various flow content
- Bit masks are applied prior to aggregation when applicable
- Test --script parameter which runs in non-interactive mode
- pep8 runs cleanly
- pylint runs cleanly as follows:
pylint --disable=I0011 --include-id=y --reports=n
All work was done against Python2.7.
Future work will include:
- For each "concept", include byte count and average packet size
(byte count/packet count).
- Toggle through the following sorting criteria:
- flow count in decreasing order: this tells us which "concepts" are
associated with the most flows in the kernel
- packet count in decreasing order then average packet size in
increasing order: this tells us which "concepts" are associated with
potentially very high packet rates
- byte count in decreasing order then average packet size in
decreasing order: this tells us which "concepts" are associated with
potentially very high throughput.
- Filter which flow concepts are aggregated
- An accumulation mode where data persists
