I am having a doubt about memory monitoring on linux system
what I should be monitoring? memory usage? o swap usage?
I am using some monitoring tools but I am confused to what monitor for alerting
for example this case
looks the memory usage is very high and it's like that all the time
so is it memory usage or swap usage? in case swap is the metric what should be threshold ?
Mem: 2738708k total, 2620784k used, 117924k free, 107872k buffers
Swap: 2104472k total, 240k used, 2104232k free, 837772k cached
thanks a lot guys
