Please help me to understand why clockskew in vnetperf output is coming in negative between node 1 and node 2.
[dbadmin@verticadb-1 ~]$ /opt/vertica/bin/vnetperf --condense -hosts 10.65.34.102,10.65.34.104
The maximum recommended rtt latency is 2 milliseconds. The ideal rtt latency is 200 microseconds or less. It is recommended that clock skew be kept to under 1 second.
test | date | node | index | rtt latency (us) | clock skew (us)
latency | 2021-09-23_23:14:22,385 | 10.65.34.102 | 0 | 46 | 2
latency | 2021-09-23_23:14:22,385 | 10.65.34.104 | 1 | 53 | -1596
Whereas in other nodes/hosts its showing possitive
Output from node 3 and node 4
[dbadmin@verticadb-1 ~]$ /opt/vertica/bin/vnetperf --condense -hosts 10.65.34.105,10.65.34.106
The maximum recommended rtt latency is 2 milliseconds. The ideal rtt latency is 200 microseconds or less. It is recommended that clock skew be kept to under 1 second.
test | date | node | index | rtt latency (us) | clock skew (us)
latency | 2021-09-23_23:12:29,348 | 10.65.34.105 | 0 | 56 | 1835
latency | 2021-09-23_23:12:29,348 | 10.65.34.106 | 1 | 60 | 511
