Shows the status of clock skew between each BDR node pair.
Synopsis Shows the status of clock skew between each BDR node pair in the cluster.
Please note that the current implementation of clock skew may return an
inaccurate skew value if the cluster is under high load while running this
command or has large number of nodes in it.
Symbol Meaning
------- --------
* ok
~ warning (skew > 2 seconds)
! critical (skew > 5 seconds)
x down / unreachable
? unknown
- n/a pgd show-clockskew [ flags] Examples
Example 1 (3 node cluster, bdr-a1 and bdr-c1 are up, bdr-b1 is down)
$ pgd show-clockskew
Node bdr-a1 bdr-b1 bdr-c1 Current Time
---- ------ ------ ------ ------------
bdr-a1 * ? * 2022-03-30 07:02:21.334472
bdr-b1 x * x x
bdr-c1 * ? * 2022-03-30 07:02:21.186809
Example 2 (3 node cluster, all nodes are up)
$ pgd show-clockskew
Node bdr-a1 bdr-b1 bdr-c1 Current Time
---- ------ ------ ------ ------------
