The log_collector.py script enables you collect the Docker log files from the containers in your deployment. The script is included in the openstack-kollacli package, which is installed on master nodes, and is located in /usr/share/kolla/kollacli/tools. You collect the log files from all nodes, or from selected nodes, as follows:

If you specify a host, the host must have been added to the deployment inventory using the kollacli host add command. If a host is not accessible, the script ignores the host and processes the next host in the list.

The script only collects logs from Docker containers whose image names start with "ol-openstack".

The script collects the logs files into a tar archive in /tmp and prints the name of the file to the screen. The archive contains a directory for each specified deployment node, and each directory contains the Docker log files for the containers deployed on that node.

The script also runs the kollacli dump command, which retrieves the configuration files and logs, and includes the output of this command in the archive.
