I've implemented a Nagios compatible monitor for the MDB freespace, but I'm trying to understand: The "unused pages" are non-fragmented, obviously The "free pages" may be scattered all over, but are completely free May there exist partially free pages that are not accounted in the monitor info? Also for a huge change request are contiguous pages needed, or is only the number of available pages important? Does MDB care about fragmentation at all? Hello Ulrich, you can also give a look to this Nagios plugin: https://ltb-project.org/documentation/check_lmdb_usage.html It uses mdb_stats command. [Windl, Ulrich] I wanted to try that first, too, but in SLES15 SP6 that command isn’t available… Clément.
