show-clockskew
==============

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

.. code:: sh

   pgd show-clockskew [flags]

Examples
^^^^^^^^

.. code:: text


     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
     ----   ------ ------ ------ ------------
     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
