Field Documentation
◆ ntnh_role
| enum m0_net_test_role ntnh_role |
Node role
Definition at line 64 of file node_helper.h.
◆ ntnh_sd
| struct m0_net_test_cmd_status_data ntnh_sd |
Node stats. Usage pattern: use ntnh_sd as primary status data structure. All statistics should go directly to this structure in thread-safe manner (from one thread or using external lock). In some inner loop m0_net_test_nh_sd_copy_lock() should be called periodically to copy ntnh_sd to ntnh_sd_copy with ntnh_sd_copy_lock locked. When status data is requested (in other thread etc.) m0_net_test_nh_sd_get_lock() should be called. It will copy ntnh_sd_copy to provided structure while holding ntnh_sd_copy_lock. This pattern will eliminate locking when updating statistics in critical testing paths at cost of delayed live stats.
