Latency¶
Transaction Processing¶
Purpose¶
Transactions should not be run by nodes over a high latency network, if possible.
Procedure¶
Log into a unified node as platform.
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 workersset 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 into a unified node as platform.
Run the following for all the UC apps under investigation:
diag ping <IP>
Record the output and share results with VOSS L2.
