Simplest way might be for example a periodic log message "I'm alive". How Does Linux Identify Processes Because Linux is a multi-user system, meaning different users can be running various programs on the system, each running instance of a program must be identified uniquely by the kernel. It is useful for monitoring system behaviour and to track down rogue processes that are spawning off processes and potentially abusing the system. The only way is for application itself being capable of indicating whether it is alive or not. Forkstat is a program that logs process fork (), exec () and exit () activity. Applications Manager is a process monitoring tool that can avoid system outages while monitor the resources consumed by Windows & Linux processes. Otherwise, as all other responders absolutely correctly commented, there is no way to find whether the process hung or not: simply because the hang might occur for way to many reasons, often bound to the application logic. hung process was killed to give a chance for a monitoring application to restart the hung instance.īut that was very very very very crude hack, done to reach an about-to-be-missed deadline and it was removed a few days later, after a fix for the buggy application was finally installed.its stack trace didn't change and time was indicating 100% CPU load after 3 checks The detection of abnormal process termination and out of memory killer is only supported on Linux on the AMD64 architecture.its stack trace didn't change and time didn't change after 3 checks.start gdb attaching to the process using its PID, dumping stack trace from it using thread apply all where, detaching from the process Htop is an interactive real-time process monitoring application for Linux/Unix-like systems and also a handy alternative to top command, which is a default process monitoring tool that comes pre-installed on all Linux operating systems.run ps to find list of PIDs of the watched processes (along with exec time, etc).I wrote a Perl script which periodically (every 30 seconds in my case): Here is how you can monitor the processes from the Truesight Operations Management Console: Go to the Infrastructure Policies tab and create a new one. Language: All Sort: Most stars winsiderss / systeminformer Star 8.9k Code Issues Pull requests Discussions A free, powerful, multi-purpose tool that helps you monitor system resources, debug software and detect malware. There is no command, but once I had to do a very dumb hack to accomplish something similar. process-monitor Star Here are 112 public repositories matching this topic. Nagios Core is an open-source Linux/Unix systems monitoring and alerting tool that can be extended through custom plugins, providing flexible Linux server monitoring. Is there any command in Linux through which i can know if the process is in hang state. Prometheus and Grafana are fully open source, so they can be downloaded and used for free.
