<dd><p>Filters a folder containing logs collected by the
<cite>oc adm must-gather</cite> command
(usually logs) with a given extension.
The time info is extracted matching each line against
the patterns passed as parameters and within the time
range between <cite>start_timestamp</cite>
and <cite>end_timestamp</cite>. if start and end timestamp
are None the bottom and top time limit
will be removed respectively. The filtering is multithreaded.
The timezone of the client and the cluster will
be applied to the filter and the records.
If a file does not contain relevant rows in the
time range won’t be written in the
dst_dir
The output of the filter will be the original file name
with all the folder structure (base
folder not included) added as a prefix and
separated by a dot, eg.
src_dir: /tmp/folder
dst_dir: /tmp/filtered
log_file: /tmp/folder/namespaces/openshift-monitoring/pods/prometheus-k8s-0/logs/current.log # NOQA
