We build a strong log-collection system to analyze total logs of our operation teams (including system ,database, web service ,load balance ,audit, cache system , hardware, iDrac logs). All of these logs are used to build a high streaming log system to find a particular performance point of our apps .We also analyze these logs in time to get a notification of attack or even a risk of event.
we use tcpcopy to make real traffic on our core systems. Many problems will be found in advance if we enlarge queries several times.

We wrote a python scripts to control redis backup work.
Three Steps to do this work:
1. Create meta database to store which redis instance needs to backup
2. Use scripts to connect to these redis instances with “–rdb” command (remote backup command)
3. Estimate which redis server should be transfered (only slave role redis will be transfered, wait minutes if a bgsave is running)
Backup Scripts: Redis_remote.py
MariaDB TokuDB benchmark on FusionIO ,Compare TokuDB and InnoDB engines.
Benchmark for NVMFS (supports atomic writes ,so we can close double-write option on specific MySQL version )
tips: some Flash-based cards could support large block map , the main idea is to avoid fractured page writes.
