Abstract: An example method for sampling an input/output (I/O) to an object owned by an object owner is disclosed. The method includes receiving an I/O and determining whether a predetermined time interval exceeds. In response that the predetermined time interval does not exceed, the example method includes calculating a first sample score associated with the object owner, obtaining a second sample score associated with a component owner of the object and calculating a weighted sample score based on the first sample score and the sample score. In response that the weighted sample score is not less than a predetermined sample score, the example method includes sampling the I/O.

Abstract: The disclosure provides a method for measuring network latency between hosts in a cluster. The method generally includes receiving, by a first host, a first ping list indicating the first host is to engage in a first ping round with a second host; executing the first ping round with the second host, wherein executing the first ping round comprises: transmitting first ping requests to the second host; calculating a network latency for each of the first ping requests; and determining a first average network latency between the first host and the second host based on each of the network latencies calculated; determining the first average network latency is above a threshold; determining a cause of the first average network latency being above the threshold; and selectively triggering or not triggering an alarm based on whether the cause is determined to be a hardware or software layer impact, or neither.
