Check LMDB Usage¶

Presentation¶

This plugin checks percent of pages used and pages free in an LMDB database.

For example:

$ perl check_lmdb_usage.pl -H /var/lib/ldap/ -w 3 -c 1 -r
OK - 66% pages used / 16% pages free

With performance data, it allows to create graph to follow evolution of this indicator.

Required Perl modules:

Getopt::Std

File::Basename

You also require the mdb_stat utility.

$ perl check_lmdb_usage.pl -H <db_home> [-S <mdb_stat>] [-h] [-v] [-V]

Mandatory Options

`-H`	Home of MDB files
`-w`	Warning threshold in percent
`-c`	Critical threshold in percent

Other options

`-S`	Path to mdb_stat utility
`-v`	Verbose
`-V`	Print version and exit
`-h`	Print help and exit
`-f`	Performance data
`-r`	Reverse mode, use warning and critical levels for free pages instead of used pages
