utilities: a top like tool for ovs-dpctl dump-flows.
This python script summarizes ovs-dpctl dump-flows content by aggregating
the number of packets, total bytes and occurrence of the following fields:
- Datapath in_port
- Ethernet type
- Source and destination MAC addresses
- IP protocol
- Source and destination IPv4 addresses
- Source and destination IPv6 addresses
- UDP and TCP destination port
- Tunnel source and destination addresses
Testing included confirming both mega-flows and non-megaflows are
properly parsed. Bit masks are applied in the case of mega-flows
prior to aggregation. Test --script parameter which runs in
non-interactive mode. Tested syntax against python 2.4.3, 2.6 and 2.7.
Confirmed script passes pep8 and pylint run as:
pylint --disable=I0011 --include-id=y --reports=n
This tool has been added to these distribution:
- add ovs-dpctl-top to debian distribution
- add ovs-dpctl-top to rpm distribution.
- add ovs-dpctl-top to XenServer RPM.
