Usage: check_memcached -H <host> [-p <port>] [-i|-I]
[-w <warning>] [-c <critical>] [-W <ratio_warn>] [-C <ratio_crit>]
[-e <slab_warn>] [-E <slab_crit> [-d <time_warning>] [-D <time_critical>]
Options:
-H STRING
Host to connect to.
-p INTEGER
Port to connect to (default: 11211).
-i
Ignore evictions of keys which do not expire.
-I
Ignore evictions of keys which have an expiration time. It's unlikely one
would want this except to complement monitoring of expiring keys (-i)
-w DOUBLE
Warning threshold for evictions per minute.
-c DOUBLE
Critical threshold for evictions per minute.
-W DOUBLE
Warning threshold for hit ratio (percent, higher is better).
-C DOUBLE
Critical threshold for hit ratio (percent, higher is better).
-e DOUBLE
Warning threshold for per-slab evictions per minute.
-E DOUBLE
Critical threshold for per-slab evictions per minute.
-d INTEGER
Warning threshold for per-slab eviction time in seconds.
-D DOUBLE
Critical threshold for per-slab eviction time in seconds.
-h
This help message
-v
Print debug messages (can be repeated up to three times)
Notes:
- If one of '-d' or '-D' is set, the per-slab thresholds ('-e' and '-E')
will be triggered only up to the evicition time thresholds. No alerts will
be sent for evictions are for keys older than the defined thresholds.
- The '-i' and '-I' switches are mutually exclusive. The default is to
consider all evictions.
