Keepalive feature is aimed at achieving Fastpath Service Assurance
in OVS-DPDK deployments. It adds support for monitoring the packet
processing threads by dispatching heartbeats at regular intervals.
keepalive feature can be enabled through below OVSDB settings.
enable-keepalive=true
- Keepalive feature is disabled by default and should be enabled
at startup before ovs-vswitchd daemon is started.
keepalive-interval="5000"
- Timer interval in milliseconds for monitoring the packet
processing cores.
v4 -> v5
* Add 3 more patches to the series
- xnanosleep()
- Documentation
- Update to NEWS
* Remove all references to core_id and instead implemented thread based
tracking.
* Addressed most of the comments in v4.
v3 -> v4
* Split the functionality in to 2 parts. This patch series only updates
PMD status to OVSDB. The incremental patch series to handle false positives,
negatives and more checking and stats.
* Remove code from netdev layer and dependency on rte_keepalive lib.
* Merged few patches and simplified the patch series.
* Timestamp in human readable form.
v2 -> v3
* Rebase.
* Verified with dpdk-stable-17.05.1 release.
* Fixed build issues with MSVC and cross checked with appveyor.
v1 -> v2
* Rebase
* Drop 01/20 Patch "Consolidate process related APIs" of V1 as it
is already applied as separate patch.
RFCv3 -> v1
* Made changes to fix failures in some unit test cases.
* some more code cleanup w.r.t process related APIs.
RFCv2 -> RFCv3
* Remove POSIX shared memory block implementation (suggested by Aaron).
* Rework the logic to register and track threads instead of cores. This way
in the future any thread can be registered to KA framework. For now only PMD
threads are tracked (suggested by Aaron).
* Refactor few APIs and further clean up the code.
RFCv1 -> RFCv2
* Merged the xml and schema commits to later commit where the actual
implementation is done(suggested by Ben).
* Fix ovs-appctl keepalive/* hang issue when KA disabled.
* Fixed memory leaks with appctl commands for keepalive/pmd-health-show,
pmd-xstats-show.
* Refactor code and fixed APIs dealing with PMD health monitoring.
