[gpfsug-discuss] 4.2 - Performance Collector node - Scaling

[Alexander Wolf]

Hi Bob,

providing crisp numbers here is a bit difficult. First it depends how
powerful (CPU, memory) the machine is where the collector runs on. But even
more it depends on the sampling frequency for the metrics that you have
configured in your sensor configuration. If you collect every 100s instead
of every second you get 1/100th of the data and will scale to much more
nodes. Therefore those numbers are more like guidelines and the real limits
depend on you individual configuration.

Mit freundlichen Grüßen / Kind regards

Hi Mike – Thanks, The documentation says “at least 400” but doesn’t define
an acceptable ratio. If you mean “don’t do more than 400” then it should
state that.

Hi Bob,

Yes, 350 nodes should be fine since it is under the 400 acceptable limit.
Generally the only concern with a large number of sensors is the volume of
data you may need to sift through.
