monitoring

I run JVisualVM (Windows XP, Sun Java 1.6.0.13, 32 bit client VM) to monitor a distant application (Linux, Sun Java 1.6.0.07, 64 bit server VM). Before starting the actual remote application, I launch on the remote machine jstatd using an all access policy: grant codebase "file:${java.home}/../lib/tools.jar" { permission java.security.AllPermission; }; Then I start the actual app using the command line java -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.port=3333 compileTest.Main From the client machine, I can see the

Similar to this question here I am trying to monitor if a set of website links are up and running or not responding. I have found the same PowerShell script over the Internet. However, instead of direct website links I need to check more specific links, for example: http://mypage.global/Chemical/ http://maypage2:9080/portal/site/hotpot/ When I am trying to check on the status of these links, I get the following output: URL StatusCode StatusDescription ResponseLength TimeTaken http://mypage.global/Chemical/ 0 http://maypage2:9080/portal/site/hotpot/ 0 The above links requires me to be connected

I'm looking for a way to monitor certain Windows services (on Windows Server 2003) and restart if necessar y. The services are on different servers and include mainly SQL Server services (e.g. SQL Server Agent), but also some proprietary services. Email alerts sent out if a service has stopped would be very useful as well. A "might be enough" version of this is built into Windows. Look into the "Recovery" tab of the service properties, as available via services.msc . You can act on a service fail with: "Restart the Service" "Run a Progam" "Restart the Computer" "Run a program" could be a small

What's the best tool that you use to monitor Web Service, SOAP, WCF, etc. traffic that's coming and going on the wire? I have seen some tools that made with Java but they seem to be a little crappy. What I want is a tool that sits in the middle as a proxy and does port redirection (which should have configurable listen/redirect ports). Are there any tools work on Windows to do this? For Windows HTTP, you can't beat Fiddler . You can use it as a reverse proxy for port-forwarding on a web server. It doesn't necessarily need IE, either. It can use other clients . Wireshark does not do port

Folks, I have a need to watch a log file for changes. After looking through stackoverflow questions, I see people recommending 'watchdog'. So i'm trying to test, and am not sure where to add the code for when files change: #!/usr/bin/python import time from watchdog.observers import Observer from watchdog.events import LoggingEventHandler if __name__ == "__main__": event_handler = LoggingEventHandler() observer = Observer() observer.schedule(event_handler, path='.', recursive=False) observer.start() try: while True: time.sleep(1) else: print "got it" except KeyboardInterrupt: observer.stop()

I am currently using jconsole to monitor performance metrics of my Java application and would like to script this data acquisition . Is there a way to retrieve these VM metrics (heap memory usage, thread count, CPU usage etc.) to STDOUT ? The data in top -p PID -b -n 1 doesn't quite cut it. Thanks jconsole just provides a wrapper around the JMX MBeans that are in the platform MBeanServer. You can write a program to connect to your VM using the Attach API which would then query the MBeans. Or you can expose the platform MBeanServer over RMI and query the MBeans that way. See the java.lang

I have a PHP script that listens on a queue. Theoretically, it's never supposed to die. Is there something to check if it's still running? Something like Ruby's God ( http://god.rubyforge.org/ ) for PHP ? God is language agnostic but it would be nice to have a solution that works on windows as well. Jay I had the same issue - wanting to check if a script is running. So I came up with this and I run it as a cron job. It grabs the running processes as an array and cycles though each line and checks for the file name. Seems to work fine. Replace #user# with your script user. exec("ps -U #user# -u
