An example for parsing osd log

./main.py -t osd -m bokeh -f <osd.log>

Now we need debug_ms=1 and debug_osd=15 for the osd's log

###OSD###
1. latency for a write and read op in one osd, reply time - start time
2. latency for an op between dequeue_op start and dequeue_op finish (time spend in osd op thread for an op)
3. latency for bluestore read op and read op size
4. latency for bluestore write allocate latency, _do_write_small
5. latency for bluestore penalty read latency
todo list

###MON###
1. latency for proposal submit 
2. Monitor flapping check
3. slow request check
4. osd healthy check (heartbeat no reply check)

###MDS###
1. cache status check
//log line
mds.0.cache Memory usage:  total 15075176, rss 14665904, heap 330416, baseline 330416, 3092793 / 3710431 inodes have caps, 3101124 caps, 0.835785 caps per inode

2. op latency
