      .LMDB monitoring statistics are now displayed correctly

      Before this update, when you tried to retrieve the monitoring statistics on an instance with Lightning Memory-Mapped Database Manager (LMDB) database type, a key error occurred. With this update, Directory Server ensures backend and monitor keys match the configured database implementation. As a result, global monitoring statistics are displayed correctly.

CMD: refreshSuffixCache: Get suffix monitor ==> dsconf -j ldapi://%2fvar%2frun%2fslapd-localhost.socket monitor backend dc=example,dc=com

      Expected results

      Should show monitoring info

      Additional information

      Error also when trying to display cache statistics in CLI:
# dsconf localhost monitor dbmon
Error: list index out of range

# dsconf localhost monitor backend dc=example,dc=com
dn: cn=monitor,cn=userRoot,cn=ldbm database,cn=plugins,cn=config

currententrycachesize: 49691
maxentrycachesize: 512000
currententrycachecount: 14
maxentrycachecount: -1
... (total 321 lines of output)


When clicking only "Database" in Monitoring tab without going into the suffix, it shows "Cache Hit Ratio NaN%" and all the values are empty.
