2020-08-13stats: remove offsets on vpp sideOle Troan1-4/+11
Represent pointers directly in shared memory and require clients to adjust for shared memory segment being mapped at different base address. Deprecated: stat_segment_pointer() / stat_segment_offset() Added: stat_segment_adjust() Bumped the stat segment version to 2. Type: refactor Signed-off-by: Ole Troan <ot@cisco.com> Change-Id: I33e756187b8903b45dcd353e6c1a101b7a4acb79
2020-08-11stats: add timeout for in_progress access to stat segmentOle Troan1-3/+39
add new api stat_segment_set_timeout_nsec to limit time waiting for vpp in_progress state. Change-Id: Ic78a97bc5013d67d7e4bbcc4a6f0ef918f9f9b33 Type: improvement Signed-off-by: Ole Troan <ot@cisco.com>
2019-08-15stats: refactor header filesDave Barach1-12/+41
Performant stat segment scraping involves caching the results of stat_segment_ls (...) and directly fishing counter data from the shared-memory segment. To do that, we need to publish several things previously hidden, declared in stat_client.c: o stat_client_main_t typedef o stat_segment_access_t typedef o stat_segment_access_start inline function o stat_segment_access_end inline function Type: refactor Signed-off-by: Dave Barach <dave@barachs.net> Change-Id: I3175e3d1f1fd8ea816336a584565179d1972115c
2019-08-09stats: create /run/vpp before stat socket bind()YohanPipereau1-0/+2
When VPP tries to bind to stats.sock it will complain about non-existing /run/vpp directory. /run/vpp is created before cli socket operations are performed. The same should be done for stat socket.

2019-06-14stats: add version field to stat segment base headerOle Troan1-0/+2
Add a version in the base header of the stat segment To make support for multiple reader implementations safer. Change-Id: I6816e2a51a98c2df1e621e80d4ef0b4ba4e9f47b Type: feature Signed-off-by: Ole Troan <ot@cisco.com>
2019-05-22stats: support multiple works for error countersOle Troan1-2/+2
The current code only allowed access to the main thread error counters. That is not so useful for a multi worker instance. No return a vector indexed by thread of counter_t values. Type: fix Change-Id: Ie322c8889c0c8175e1116e71de04a2cf453b9ed7 Signed-off-by: Ole Troan <ot@cisco.com>
