Instance Balancer Spread CPU cores among running instances of application(s). Limit Instances Limit the number of instances a process may have in a user session. Disallowed Processes Immediately terminate any matched process, by your criteria. Priority Classes Set persistent CPU, I/O, and memory priorities so that processes run at the desired priorities every time they launch. CPU Sets A ‘softer’ form of CPU Affinities that are more like preferred cores. CPU Affinities Set persistent CPU affinities so that processes run on the desired set of CPUs every time they launch. Memory usage is also useful.Features ProBalance ProBalance is our famously efficacious algorithm to maintain PC responsiveness during high CPU loads. For a sudden influx of usage you may want a list of network connections (by address not name).

You may want a lot of information besides just the processes using the most resources. You may find that cfengine's anomaly detection can be used to trigger a script to capture the system state when things go wrong. The system admin kept insisting the increasing swap usage was not a problem, right up until the server stopped responding. The problem service was a program monitoring other processes for memory leaks. I once watched a server slowly die over a period of days. You may be able to correct the problem before it goes down.įor memory leaks, a steady increase in swap usage indicates a problem. This may give you a chance to get in and watch the server going down. I realize this is server based, but it useful to determine times when problems are occurring. I have configured systems to run top for a few cycles when a resource was being over used.Ĭonsider running sar in batch mode to capture resource utilization. You may need more than one top running to capture the top offenders on multiple resources. It you want just the top offenders, consider running top with a relatively long interval (60 seconds plus) in batch mode.
