  2. Not frequent buy and sell (as profit >5%)
  3. Long win with least loss
  4. Split capital in phrases, not all in the same price;
  5. Work hard to study and prepare to set price for big drop
  6. No guess, no gambling
  7. Reliable publishers of warrants, such as HSBC, (not credit su…)

    3. Customizing Performance Monitor: https://technet.microsoft.com/en-us/library/2008.08.pulse.aspx
    4. Components: baselines / benchmark sampling intervals / counters / centralized monitor
    5. Commong bottlenecks in Five areas: Physical disk, memory, process, CPU, and network.
    6. Sampling intervals: balance size of log file and server load
      1. 15 minutes: good window to establishing baseline;
      2. 15 seconds: average elapsed time for a 4-hour issue;
      3. 5 minutes: average elapsed time for a 8-hour issue
    7. Guidelines (https://technet.microsoft.com/en-us/library/2008.08.pulse.aspx):
      1. Disk
        1. LogicalDisk\% Free Space: alert at <15%; consider add space;
        2. PhysicalDisk\% Idle Time: saturated <20%; consider replacing faster disk system;
        3. PhysicalDisk\Avg. Disk Sec/Read OR PhysicalDisk\Avg. Disk Sec/Write : alert at >25ms; 10ms for SQL & Exchange server; consider replacing faster disk system;
        4. PhysicalDisk\Avg. Disk Queue Length: alert at > 2x of the number of spindles;
        5. Memory\Cache Bytes: memory being used for file system cache; alert at >300MB;
      2. Memory
        1. Memory\% Committed Bytes in Use: amount of virtual memory in use, alerts at >80%; consider add more memory;
        2. Memory\Available Mbytes: alerts at < 5%; consider add more memory;
        3. Memory\Free System Page Table Entries: maybe memory leak for <5000;
        4. Memory\Pool Non-Paged Bytes: maybe memory leak for >175MB;
        5.  Memory\Pool Paged Bytes: mayge memory leak for >250MB;
        6. Memory\Pages per Second: alerts at >1000 as a result of excessive paging, maybe memory leak;
      3. Processor
        1. Processor\% Processor Time: alerts at >85%; consider replace faster processor;
        2. Processor\% User Time: elapsed time the processor spends in user mode; alerts at high value; consider optimize the applications;
        3. Processor\% Interrupt Time: processor spends receiving and servicing hardware interruptions; possible hardware issue if > 15%;
        4. System\Processor Queue Length: alerts at 2x No. of CPUs; not enough processing powers;
      4. Network
        1. Network Interface\Bytes Total/Sec: Send and receive per NIC; saturated if > 70%; for 100MB NIC, alerts at >8.7MB/sec;
        2. Network Interface\Output Queue Length: network saturation if  >2; consider faster NIC or segmenting network;
      5. Process
        1. Process\Handle Count: total number of handles that are currently open by a process; alerts at >10,000 for handle leak;
        2. Process\Thread Count: number of threads currently active in a process, alerts at >500 between min. and max.;
        3. Process\Private Bytes:  memory allocated that cannot be shared with other processes; alerts at >250 of thread leakage between min. and max. 
      6. Conclusion:
        1. save as templates for later use
        2. remote monitoring is good practice but cannot monitor server that is running out of resources;
