api: Implement log_dump/log_details
- Replaces the need to screen scrape "show log". - Adds an api to return the system time. When running over a socket, the api client may have different time than the vpp host. expected use: vpp_time_before_command = self.vapi.show_vpe_system_time_ticks().vpe_system_time_ticks <run some commands> log_output = self.vapi.log_dump(start_timestamp=vpp_time_before_command) Depends-on: https://gerrit.fd.io/r/20484 Depends-on: https://gerrit.fd.io/r/#/c/19581/ ============================================================================== TestVpeApi ============================================================================== log_details(_0=838, context=3, timestamp_ticks=2.4954863503546518e+48, level=<vl_api_log_level_t.VPE_API_LOG_LEVEL_WARNING: 4>, timestamp=u'2019/07/04 20:35:41:281', msg_class=u'buffer', message=u'vlib_physmem_shared_map_create: clib_mem_create_hugetlb_fd: open: No such file or directory\n\n') log_details(_0=838, context=3, timestamp_ticks=1.6101902879480125e+159, level=<vl_api_log_level_t.VPE_API_LOG_LEVEL_WARNING: 4>, timestamp=u'2019/07/04 20:35:41:281', msg_class=u'buffer', message=u'falling back to non-hugepage backed buffer pool') test_log_dump_default (test_vpe_api.TestVpeApi) OK log_details(_0=838, context=13, timestamp_ticks=2.4954863503546518e+48, level=<vl_api_log_level_t.VPE_API_LOG_LEVEL_WARNING: 4>, timestamp=u'2019/07/04 20:35:41:281', msg_class=u'buffer', message=u'vlib_physmem_shared_map_create: clib_mem_create_hugetlb_fd: open: No such file or directory\n\n') log_details(_0=838, context=13, timestamp_ticks=1.6101902879480125e+159, level=<vl_api_log_level_t.VPE_API_LOG_LEVEL_WARNING: 4>, timestamp=u'2019/07/04 20:35:41:281', msg_class=u'buffer', message=u'falling back to non-hugepage backed buffer pool') test_log_dump_timestamp_0 (test_vpe_api.TestVpeApi) OK test_log_dump_timestamp_future (test_vpe_api.TestVpeApi) SKIP test_show_vpe_system_time_ticks (test_vpe_api.TestVpeApi) SKIP ============================================================================== TEST RESULTS: Scheduled tests: 4 Executed tests: 4 Passed tests: 2 Skipped tests: 2 ============================================================================== Test run was successful Type: feature Change-Id: I893fc0a65f39749d2091093c2c604659aadd8447 Signed-off-by: Paul Vinciguerra <pvinci@vinciconsulting.com>
