1.5. GATHERING LOGS FROM MULTIPLE HOSTS IN A CEPH CLUSTER USING ANSIBLE
Starting with Red Hat Ceph Storage 4.2, you can use ceph-ansible to gather logs from multiple hosts in a Ceph cluster. It captures etc/ceph and /var/log/ceph directories from the Ceph nodes. This playbook can be used to collect logs for a bare-metal and containerized storage cluster.

Prerequisites

A running Red Hat Ceph Storage cluster.
Root-level access to the nodes.
The ceph-ansible package is installed on the node.
Procedure

Log into the Ansible administration node as an ansible user.

Note
Ensure the node has adequate space to collect the logs from the hosts.

Navigate to /usr/share/ceph-ansible directory:

Example

[ansible@admin ~]# cd /usr/share/ceph-ansible
Run the Ansible playbook to gather the logs:

Example

ansible@admin ceph-ansible]$ ansible-playbook infrastructure-playbooks/gather-ceph-logs.yml -i hosts
The logs are stored in the /tmp directory of the Ansible node.
