BPA – Configuring thresholds for RTT values in NATS (Supercluster/Leaf nodes config)?

Hi Dojo,

In this staging environment I get the following BPA warning for SLNET connections,
yet the RTT value is expected, as this communication involves international WAN link:

is there a way to redefine the assigned thresholds of the BPA for this specific check?

Additional info: 57ms is actually pretty good in terms of WAN link performance for these 2 endpoints - custom NATS topology was implemented in the cluster - and the host with 57ms is a leaf node in terms of NATs config, while the other belongs to the "Core".

Thanks

EDIT: adding DM version info --> DataMiner (10.5.0.0-15943-CU4)

Hello Alberto,

In the current implementation of the “Check Cluster SLNet Connections” BPA, the maximum round-trip time is defined as a constant with a fixed value of 50 ms, and therefore cannot be changed.

We will evaluate whether this limit can be made configurable in a future version of the BPA.

Until then, I’m afraid you will need to ignore the warning message being generated.

Cheers,
Paulo

Thanks for your feedback Paulo – feature suggestion added:

Ad interim, is the rule available on the DMA to tweak that value to 80ms for example?

That would give us a better perception of unexpected delays in our environment.
