Nice, thanks for adding :) I think this does not fully fix the issue. Adding the flags changes the in-memory layout of the counters. It remains to add those to the struct, replacing the 'padding' field, and then to extrapolate the counters based on the fraction of enabled/running. |

i think it's quite a different approach to how we currently do things, and i'm not qualified to rewrite this so we may need to find someone who knows what they're doing. |

SG. In the meantime, probably best to revert this commit. |
