For systems running on-line, current database performance monitoring typically monitors the following points:(1) Whether there is obstruction (Blocking);(2) whether there is waiting (waiting), blocking is the lock (locks) waiting;(3) Whether the running time is too long (long running);(4) Whether there is a deadlock (Deadlock);Sys.dm_exec_query_stats and so on, and so on some statistical information, usually not as the real-time alarm content, but in
value is less than 5m, SQL Server may have a performance bottleneck due to lack of memory. 4.Physical Disk:% Disk Time This counter records how busy the disk is (the entire disk array or the physical disk is busy). Theoretically this value should be less than 55%, if it lasts more than 55%, that indicates that there may be an IO bottleneck on this server. If only occasionally appear several times, that does not need to worry, but can correspond to fi
I was so busy recently that I wrote last night that I fell asleep. Well, let's write the Java framework.Logs and certain monitoring in any system are very important. maintenance during the entire life cycle of a software is always a big headache at the same time, log and monitoring provides a good foundation and means for later maintenance. In Java projects, most log4j is used to record system logs. Almost

Monitoring SQL Server Transactional replicationIn general, we can use the Replication Monitor in SSMs to monitor replication. But we can't stare at it for 24 hours, and we have to use an automated way to monitor it.
