Description Michel Smidt 2017-11-09 22:51:24 CET

To monitor larger environments it is necessary to check for the remaining capacity of the mdb database. The customer had several support cases where especially the database maxsize (ldap/database/mdb/maxsize) and listener cache size (listener/cache/mdb/maxsize) were exceeded.
So, it would be very helpful to get Nagios checks for this mdb limits.
E.g. The customer MDB LDAP limit: 12884901888, effective size: 6442450944, full: 50%

 * added new nagios plugin check_univention_slapd_mdb_maxsize 
   (check_univention_slapd_mdb_maxsize_suidwrapper), checks the total and free
   pages of the mdb ldap database (lmdb-utils) and returns warning if 75%
   or critical if 90% of the total pages are in use
 * 26univention-nagios-common.inst
   add new nagios service UNIVENTION_SLAPD_MDB_MAXSIZE
 * 30univention-nagios-client.inst
