I'm looking at a Prometheus graph of cn=Read,cn=Waiters,cn=Monitor (slapd 2.4.59).

The object class is monitorCounterObject, the attribute is called monitorCounter.

If it's a counter I'd expect the value to only increase.

But the graph shows decreasing values!?!

What's the exact meaning of this?

It's an instantaneous/current count, not cumulative.

The number of connections currently blocked waiting for data from the client.

write waiters is the number of connections blocked waiting to send data to the client.

Hmm, so the schema used beneath cn=Threads,cn=Monitor would be more appropriate.
