ID: 12511 Title: Any custom Perf-O-Meter destroyed all Perf-O-Meters Component: Setup Level: 1 Class: Bug fix Version: 2.1.0i1 Users can implement their own Perf-O-Meters in <i>local/share/check_mk/web/plugins/perfometer</i>. Whenever a user did that in Checkmk 2.0.0 to 2.0.0p3, <b>all</b> Perf-O-Meters vanished. Instead the error message "Exception: _required_names" was displayed.
