How to Get Per Process Disk Activity in Windows

由 こ雲淡風輕ζ 提交于 2019-11-30 16:03:13
问题 I need to extract disk statistics for a given process, I can get the processes listed and get overall information such as CPU and Memory listed using WMI and PerformanceCounters. But the information is all bundled up, is there any way to extract those data per process. Kind of like in Windows Resource Monitor? Thanks in Advance 回答1: If you need live data, you should implement ETW listener. ETW are the way of tracing performance information in Windows. It is supported back to Windows 2000.

问题 is there anyone know how to monitor a folder using java? or anyone could gave me a point that how could i start this. here's my thought about it. start a thread to scan the folder changes,which could be create,delete,update files in this folder or something else happen,like last updated. but in this case, you have to control thread loop. if this thread loop is not controlled well,then it would be a waste of cpu and may cause a fatal problem. or,is there any framework or some demo code to do

How to monitor MySQL query errors, timeouts and logon attempts? [closed]

由 人盡茶涼 提交于 2019-11-30 14:12:11
While setting up a third party closed source CMS (Sitefinity) the setup doesn't create all tables and procedures necessary to run it. The software lacks a logging system itself and it made me wonder: could I trace and monitor failing SQL statements from MySQL? This serves more than only the purpose of solving my issue with Sitefinity. More often I wonder what's send to the MySQL server, not wanting to dive into the software products or setup a debugging environment etc. I tried JetProfiler (only performance) and looked through a few others , but although they monitor a lot, they don't monitor

I need to programmatically start a new java process and dynamically set the JMX port. So instead of doing this -Djava.rmi.server.hostname=127.0.0.1 -Dcom.sun.management.jmxremote.port=9995 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false I would like to do the following System.setProperty("java.rmi.server.hostname", "127.0.0.1" ); System.setProperty("com.sun.management.jmxremote", "true" ); System.setProperty("com.sun.management.jmxremote.authenticate", "false" ); System.setProperty("com.sun.management.jmxremote.ssl", "false" ); System.setProperty("com

问题 I'm trying query a remote JVM with jps using jstatd, in order to eventually monitor it using VisualVM.

Finding out what network sockets are open in the current Java VM

由 限于喜欢 提交于 2019-11-30 06:23:17
问题 I'm writing an end-to-end test that my Java program releases all of its resources - threads, server sockets, client sockets. It's a library, so releasing resources by exiting the JVM is not an option. Testing the releasing of threads was easy, because you can ask a ThreadGroup for all threads in it, but I haven't yet found a good way to get a list of all network sockets that the current JVM is using. Is there some way to get from a JVM the list of all client and server sockets, similar to

.Net SQL Server Database Monitoring - Insert, Update, Delete

由 这一生的挚爱 提交于 2019-11-30 05:24:17
Does anyone know of a way to monitor table record changes in a SQL Server (2005 or 2008) database from a .Net application? It needs to be able to support multiple clients at a time. Each client will "subscribe" when it starts, and "unsubscribe" when it exits. Multiple users could be accessing the system at once and I want to reflect their changes on the other users client. Then when the client handles the change event, it could update it's local object representing that record. Kind of similar to how Access updates records that are modified are reflected in each form referencing it. I know
