cluster show clockskew v5.6
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 it 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 cluster show clockskew [flags]
Examples
With skew issues
In this example with a 3 node cluster, bdr-a1 and bdr-c1 are up but bdr-b1 is down.
$ pgd cluster show clockskew
Output
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
Without skew issues
In this example with a 3 node cluster, all nodes are up.
$ pgd cluster show clockskew
Output
Node bdr-a1 bdr-b1 bdr-c1 Current Time ---- ------ ------ ------ ------------ bdr-a1 * * * 2022-03-30 07:04:54.147017 bdr-b1 * * * 2022-03-30 07:04:54.340543 bdr-c1 * * * 2022-03-30 07:04:53.90451
