+Something weird, 
+
+
+I found out that there is no db end tracing log .
+
+
+There is 'end tracing ' initial install phase.
+The rocksdb instance is shutdown gracefully .
+
+How can I run a graceful shutdown.

+- Gracefully shutdown a process
+https://stackoverflow.com/questions/690415/in-what-order-should-i-send-signals-to-gracefully-shutdown-processes
+
+`kill -15 $pid`
+
+Now there is end tracing log in the LOG
+
+I need to check the startTrace code to see if the new trace file will overwrite the existing one.
+
+But there is still error while parsing op trace file.
+
+
+I check the `env/fs_posix.cc`
+The file will be truncated.
+
+
+## Fix a bug which I don't know why 
+
+- Bug description
+  When I run `trace_analyzer` to parse the op_trace_file, the 
+  `Iterate()` function in `write_batch.cc` reports error while executing
+  `MarkNoop()` function, the handler does not over write the `MarkNoop()`
+  function from `Handler`, so it calls methods from parents which returns
+  invalid status, thus causing a error.
+
+
+- My fix
+  I just add the `MarkNoop()` override function in the `Classifier` Handler.

+I think I found a bug ? 
+
+The timestamp in io trace file does not make sense 
+record timestamp:100853315672962
+
+
+start timstamp: 1661002238043735
+
+time I get with the bash command `date +%s%N`
+1661073847698401833
+
+Turns out  that record timestamp is return by NowNanos()
+And start timestamp is return by NowMicros();
+
+I don't know why the it is, I think it's a bug.
+
+So I will just submit a pr, fix this.
+
+
+How linux get nano time 
+```
+  uint64_t NowNanos() override {
+#if defined(OS_LINUX) || defined(OS_FREEBSD) || defined(OS_GNU_KFREEBSD) || \
+    defined(OS_AIX)
+    struct timespec ts;
+    clock_gettime(CLOCK_MONOTONIC, &ts);
+    return static_cast<uint64_t>(ts.tv_sec) * 1000000000 + ts.tv_nsec;
+#elif defined(OS_SOLARIS)
+```
+
+
+
+Check the source code and run a test by myself,
+
+Found that it's because there is subttle difference.
+
+```
+# define CLOCK_REALTIME			0
+/* Monotonic system-wide clock.  */
+# define CLOCK_MONOTONIC		1
+/* 
+```
+
+
+```
+  uint64_t NowNanos()  {
