Webmasters who use MSSQL will be admired by the ability of the MSSQL database to eat memory.

Some people think that MSSQL has a memory leakage problem

Linux vmstat CommandsThe Vmstat command is the most common Linux/unix monitoring tool that can represent the state values of a server at a given time interval , including the server's CPU usage, memory usage, virtual memory exchange situation , IO Read and write situations. compared to top, I can see the CPU,

Unity3d provides us with a powerful profiler for profiling tools. Today we use Profiler to analyze in detail the official example Angrybots memory usage information data.First Open Profiler Select memory option, in the game run a frame to view the detailed option data (Simple mode of data is very intuitive, you can know that the

will also increase memory usage. If you have server health monitoring, remember that this frequency should not be too high. Otherwise, health monitoring will become a disease-caused monitoring.Jstat can be used to monitor the GC heap and GC of JVM. For example, the monitoring process refresh every 837 milliseconds and outputs 20 times: The code is as follows:Co

between a message publisher and a subscriber, and Redis acts as a pub/sub server, with the ability to route messages between subscribers and publishers. A subscriber subscribes to a message type of interest to redis through the subscribe and Psubscribe commands, and Redis makes the information type channel. When a publisher sends a specific type of information to Redis server through the close Publish command, all clients subscribing to that message type receive this message.For example, open t

Recently, some processes in the online environment always experience memory overflow. Therefore, we need to add a monitor on the memory usage of some processes. Most of the scripts found by others are not satisfactory, so I wrote one myself, code: 123456789101112131415161718192021222324252627282930313233343536373839404

Label:Background: Production of a Redis server, physical memory 32G, several projects are in use, often less than a month memory will be exhausted, and then start to use Swap, when the swap is exhausted, the system will go down. The Redis configuration has also been optimized several times, but no results have been achieved. So I decided to look at the memory siz

Windows has triggered a breakpoint in xxx.exe The memory usage error can be inferred from this error, but this error is hidden.
