Branch: refs/heads/2.0.0 Home: https://github.com/tribe29/checkmk Commit: b033a68ea68b1d10b27ba719d74a3c041782999f https://github.com/tribe29/checkmk/commit/b033a68ea68b1d10b27ba719d74a3c041… Author: Moritz Kiemer &lt;moritz.kiemer(a)tribe29.com&gt; Date: 2023-02-20 (Mon, 20 Feb 2023) Changed paths: A .werks/15237 M cmk/gui/plugins/metrics/translation.py M cmk/update_rrd_fs_names.py Log Message: ----------- 15237 FIX Deal with 'messed up' RRD files In some particular update scenario, users would see a message about 'messed up' RRD files: <i>"RRD files for host myHost [...] are messed up. Please restore them both from backup."</i> This case is now properly handled. Technical details: Older filesystem metrics have been created using the mount as metric name, leading to a lot of differently named metrics. We have since changed the metric name to the predictable (and reusable) name 'fs_used'. The migration failed in cases where for some reason both the old and the new metric are present. In this case we now create the artificial metric <tt>fs_used_renamed_legacy_records</tt> from the old values, which will be prepended to the new metric to provide the full history of RRDs.
