Latency#
Transaction Processing#
Purpose#
Transactions should not be run by nodes over a high latency network, if possible.
Procedure#
Log in on any unified node (multinode unified topology) / application node (modular cluster topology).
Run the following for all the other nodes:
diag ping <IP>
If any of the average round trip time is higher than 10ms, it is recommended that the nodes in the secondary DC should have
voss workers
set to 0 on version 11.5.3 and later, or the command app stop voss-queue is run on older versions.
Note
For software versions pre 11.5.3, the app stop voss-queue command needs to be run after every service restart or server reboot.
UC Apps Latency#
Purpose#
Latency between unified nodes and UC apps impacts overall provisioning times against the UC apps. This check is done as part of diagnosis of provisioning performance problems.
Procedure#
For each data center:
Log in on any unified node (multinode unified topology) / application node (modular cluster topology).
Run the following for all the UC apps under investigation:
diag ping <IP>
Record the output and share results with VOSS L2.
