ID: 6436 Title: Prevent metrics with "," in their names from breaking graphs Component: Multisite Level: 1 Class: Bug fix Version: 1.6.0i1 When a metric name contains a ",", possibly due to another error, this could break all graphs of a service. The metric system now totally skips these metric names to prevent this. The graphs that can be rendered successfully are now displayed again in such a situation.
