Issue ID: 9661
Summary: How to monitor an LDMB file for being pretty full
Product: LMDB
Version: unspecified
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: ---
Component: liblmdb
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
https://ltb-project.org/documentation/nagios-plugins/check_lmdb_usage provides
a Nagios plugin, to check how full/free a LMDB database is. It calls mbd_stat
-ef, and parses from the output the numbers in the “Max pages:”, “Number of
pages used:”, and “Free pages:” lines.
With these numbers it calculates “the percent of used pages” or “the percent of
free pages” and signals the status with return values 0 -OK, 1 - warning, or 2
- critical . The disadvantage of check_lmdb_usage is, that it requires perl.
Do you recommend to monitor the absolute number of free pages, the relative
number of free pages, the absolute number of used pager, or the relative number
of used pages?
Please extend mdb_stat to be suitable for monitoring the fullness of a LMDB
directory - accept parameters of for a warning and critical threshold, and a
parameter on how to calculate the criterion (A - based on absolute number of
free pages, B - relative number of free pages, C - absolute number of used
pages, or D - relative number of used pages).
