* ctdb-scripts: Drop script configuration variable CTDB_MONITOR_SWAP_USAGEMartin Schwenke2019-05-072-22/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | CTDB's system memory monitoring in 05.system.script monitors both main memory and swap. The swap monitoring was originally based on the (possibly incorrect, see below) idea that swap space stacks on top of main memory, so that when a system starts filling swap space then this is supposed to be a good sign that the system is running out of memory. Additionally, performance on a Linux system tends to be destroyed by the I/O associated with a lot of swapping to spinning disks. However, some platforms default to creating only 4GB of swap space even when there is 128GB of main memory. With such a small swap to main memory ratio, memory pressure can force swap to be nearly full even when a significant amount of main memory is still available and the system is performing well. This suggests that checking swap utilisation might be less than useful in many circumstances. So, remove the separate swap space checking and change the memory check to cover the total of main memory and swap space. Test function set_mem_usage() still takes an argument for each of main memory and swap space utilisation. For simplicity, the same number is now passed twice to make the intended results comprehensible. This could be changed later. A couple of tests are cleaned up to no longer use hard-coded /proc/meminfo and ps output. Signed-off-by: Martin Schwenke <martin@meltin.net> Reviewed-by: Amitay Isaacs <amitay@gmail.com>

| | | | | | | | | | This provides finer resolution while still maintaining a reasonable maximum. In this case the top bucket contains any hop counts >= 16384, compared to the current situation where the top bucket contains hop counts >= 268435456.
