David Garcia Quintas	9b0a94b5c7	Further fixes and eye candy. In particular, fixed the handling of } when nesting gets complex. Made the reporting of block percentiles consistent with the ! reporting.	10 years ago
David Garcia Quintas	7cff3ee205	Handling of ! tags across threads & performance. Fixed an important bug whereby thread info wasn't being taken into account for ! marks. Also dramatically improved performance by getting rid of a silly O(n^2) loop.	10 years ago
David Garcia Quintas	975efdc915	Avoid repeated sortings in percentile() calls. Have the function expect sorted input.	10 years ago
David Garcia Quintas	776075a80a	Implemented aggregation over important mark times. Namely, 50,90,95 and 99th percentiles are now reported on important marks. Example output (for a single ! mark between begin-end marks in grpc_tcp_write()): ``` Important marks: ================ 99999@src/core/iomgr/tcp_posix.c:545 Relative mark: 50th p. 90th p. 95th p. 99th p. 205 { (src/core/iomgr/tcp_posix.c:541): 0.037 0.057 0.070 0.087 205 } (src/core/iomgr/tcp_posix.c:556): 15.181 27.021 32.509 41.103 ``` For a fabricated example (see https://gist.github.com/dgquintas/026d333815589cc37269) with the same ! mark in two different frames, the output is: ``` Important marks: ================ 999999@src/core/iomgr/tcp_posix.c:5 Relative mark: 50th p. 90th p. 95th p. 99th p. 205 { (src/core/iomgr/tcp_posix.c:1): 9.500 13.900 14.450 14.890 205 } (src/core/iomgr/tcp_posix.c:6): 3.000 4.600 4.800 4.960 999999@src/core/iomgr/tcp_posix.c:3 Relative mark: 50th p. 90th p. 95th p. 99th p. 205 { (src/core/iomgr/tcp_posix.c:1): 2.500 2.900 2.950 2.990 205 { (src/core/iomgr/tcp_posix.c:2): 1.500 1.900 1.950 1.990 205 } (src/core/iomgr/tcp_posix.c:4): 2.000 2.800 2.900 2.980 205 } (src/core/iomgr/tcp_posix.c:6): 10.000 15.600 16.300 16.860 ```	10 years ago
David Garcia Quintas	5b2ea2979b	Added support for important mark (!) analysis. For example, an input of GRPC_LAT_PROF 1316908107613.015869 0x7fd35f7fe700 { 205 (nil) src/core/iomgr/tcp_posix.c 1 GRPC_LAT_PROF 1316908107614.015869 0x7fd35f7fe700 { 205 (nil) src/core/iomgr/tcp_posix.c 2 GRPC_LAT_PROF 1316908107615.015869 0x7fd35f7fe700 ! 999999 (nil) src/core/iomgr/tcp_posix.c 3 GRPC_LAT_PROF 1316908107616.015869 0x7fd35f7fe700 } 205 (nil) src/core/iomgr/tcp_posix.c 4 GRPC_LAT_PROF 1316908107617.015869 0x7fd35f7fe700 ! 999999 (nil) src/core/iomgr/tcp_posix.c 5 GRPC_LAT_PROF 1316908107618.015869 0x7fd35f7fe700 } 205 (nil) src/core/iomgr/tcp_posix.c 6 results in tag 50%/90%/95%/99% us 205 5.00/5.00/5.00/5.00 Important marks: ================ 999999 @ src/core/iomgr/tcp_posix.c:3 205 { (src/core/iomgr/tcp_posix.c:1): 2.000 us 205 { (src/core/iomgr/tcp_posix.c:2): 1.000 us 205 } (src/core/iomgr/tcp_posix.c:4): -1.000 us 205 } (src/core/iomgr/tcp_posix.c:6): -3.000 us 999999 @ src/core/iomgr/tcp_posix.c:5 205 { (src/core/iomgr/tcp_posix.c:1): 4.000 us 205 } (src/core/iomgr/tcp_posix.c:6): -1.000 us	10 years ago
