Report the Endpoint Status for etcd Clusters

Report etcd cluster end point status. The report includes a cluster’s endpoint, database size, and leader status.

This procedure provides the ability to view the etcd cluster endpoint status.

Prerequisites

  • This procedure requires root privileges.
  • The etcd clusters are in a healthy state.

Procedure

  1. (ncn-mw#) Report the endpoint status for all etcd clusters.

    /opt/cray/platform-utils/etcd/etcd-util.sh endpoint_status all_clusters

    Example output:

    ### cray-bos-bitnami-etcd-1 Endpoint Status: ###
+----------------+------------------+---------+---------+-----------+------------+-----------+------------+--------------------+--------+
|    ENDPOINT    |        ID        | VERSION | DB SIZE | IS LEADER | IS LEARNER | RAFT TERM | RAFT INDEX | RAFT APPLIED INDEX | ERRORS |
+----------------+------------------+---------+---------+-----------+------------+-----------+------------+--------------------+--------+
| 127.0.0.1:2379 | 6a95fcc74f1f8616 |   3.5.7 |   25 kB |     false |      false |         7 |        420 |                420 |        |
+----------------+------------------+---------+---------+-----------+------------+-----------+------------+--------------------+--------+

  2. Report the endpoint status for a singe etcd cluster.

    /opt/cray/platform-utils/etcd/etcd-util.sh endpoint_status cray-bos

    Example output:

    ### cray-bos-bitnami-etcd-1 Endpoint Status: ###
