Is there someone that needs the counter below? There are hardly any customers using buffer pool extensions. If not needed please remove that and will aprrove.
Extension free pages | Total number of free cache pages in the buffer pool extension file.
@denzilribeiro I've removed the buffer manager counters |

These were added recently as part of PR - #8120, however these counters are rarely used (Denzil's comment above mention the same), hence were removed.

@ssoroka your decision here. #8120 was merged on Sept. 2020 and thus was release in 1.17.
My question to @denzilribeiro is if it was intended to be added here, why do you now remove it. In general, what is the cost of keeping those two in there?

@srebhan - to be honest should have not been added as rarely ( < 0.5%) do SQL Server folks use it. Removal was more from perspective of unnecessary space, not opposed to leaving it but if 99.9% are not using the feature that enables those counster, let alone the montiroing for it it then why? But you guys' call

It's possible if someone is using it this could break a chart. I'm on the fence here, but if it's all the same to everyone let's just leave the fields in and they can always drop the ones they don't want.

@danielnelson / @ssoroka / @sjwang90 can someone help merge this or are there pending issues that need to be addressed? |

@denzilribeiro We'll get this reviewed and let you know if there's anything else before it gets merged. Thanks! |

I think the removal of the two properties needs to be agreed on by someone from InfluxData. Alternatively, you could leave those lines in if it is not prohibitively costly (my preferred solution).
@srebhan - Reverted the removal of the two counters. |
