Description

I notice that the "peak" memory as reported by SimpleMemoryCheck always matches one of the memory report entries.
Linux provides another estimation of the real peak memory (possibly a better one).
This figure is important in environments with limited resources and can differ sensibly from the reported peak.
That number can be found as VmPeak in /proc/PID/status.

I think we can add this as an additional piece of information rather than by changing the way we calculate this particular number. That way we can actually see any discrepancies between the two metrics.

#7 Updated by Kyle Knoepfel over 5 years ago

We have addressed a number of issues related to SimpleMemoryCheck, as implemented with commit fbc282dd. We are also developing a new memory service called MemoryTracker that will be sqlite3-driven, just as the new TimeTracker service is. Since VmPeak is a feature to be added to the service, we will include it in MemoryTracker and refrain from adding additional data to SimpleMemoryCheck.

The new MemoryTracker service has been implemented. The VmPeak quantity is now given at the top of the general summary.

Implemented with 66bcc29c.
