问题 Current state is like this: Nginx -> HHVM -> PHP5-FPM. When HHVM crashes (quite often) it returns 502 error. I did @fallback workaround to nginx configuration, but I need to manually restart hhvm. here Automatically restarting HHVM when it stops responding but process not dead some PID listener cron is described, but sometimes hhvm just unresponsive with existing pid. How to monitor this? 回答1: I have the exact same problem - HHVM becomes unresponsive randomly (I haven't figured out why yet)

问题 I would monitoring the smart HDD-s on my Windows 7 clients. I would to get the HDD smart attributes without using any vbs file or ready-made tool just looking towards WMI or PowerShell. I would aggregate that data with ZABBIX monitoring server (use zabbix-sender.exe ). I found a more or less solution for Linux, but I would monitor windows 7 machines HDD. Has anyone an idea? 回答1: Use the WMI API to access SMART data like so, gwmi -namespace root\wmi -class MSStorageDriver_FailurePredictStatus

问题 Situation: Site with content protected by username/password (not all controlled since they can be trial/test users) a normal search engine can't get at it because of username/password restrictions a malicious user can still login and pass the session cookie to a "wget -r" or something else. The question would be what is the best solution to monitor such activity and respond to it (considering the site policy is no-crawling/scraping allowed) I can think of some options: Set up some traffic

问题 I am new to Java and I'm facing a problem in connecting a Remote Host to the JVisualVM . I've searched the Internet and followed all the steps mentioned there but still am not able to resolve the issue. The steps I followed are: I started the jstatd on the remote server by first creating a jstatd.all.policy file in the $JAVA_HOME/bin . The file contained: grant codebase "file:${java.home}/../lib/tools.jar" { permission java.security.AllPermission;}; I started the Jstatd as jstatd -J-Djava

问题 I'm dealing with an application using multiple microservices. The application receieves data and processes it, and I'd like to have a way to monitor everything the received data is going throughout the microservices. Since the platform is nodejs we're dealing with asynchronous processing, logs wont always be written one after the other, and since the data does not have aמ ID the logs cannot be filtered in any convenient way. Is there any way to track the data from the first moment it enters

问题 I'm working on a small clipboard manager which should remember recent copied text. I'm using Windows system messages for being notified when something has been copied to clipboard by WM_DRAWCLIPBOARD. The problem is some of the applications I use send multiple WM_DRAWCLIPBOARD messages to my application, for instance when I copy something in Chrome web browser it's only one message, miranda's chat window sends 3 of the same messages with the same text to the clipboard viewer's chain. How to

问题 I have a TFDMoniFlatFileClientLink on a form, filename set to d:\temp\monitor.txt , tracing=true, TFDConnection.Params.MonitorBy=mbFlatFile . This sometimes works and sometimes does not trace anything. No file gets created. Tested with Win7 32-bit app, with design time TFDConnection to either FireBird or Oracle. Delphi Tokyo 10.2.1 What is going on? 回答1: This was a really weird bug: It turns out that the TFDMoniFlatFileClientLink remembers the filename when removed and placed back, then does
