If this option is False (the default) and ip6\_tables module couldn't be loaded, the charm will fail to install. * connection-limit | int Default: 1024 maximum simultaneous connections (memcached option -c) * disable-auto-cleanup | boolean do not remove things automatically from the cache on OOM (memcached option -M) * disable-cas | boolean disable use of CAS (and reduce the per-item size by 8 bytes) * disable-large-pages | boolean The charm will will try to use large pages if given more than 2GB of RAM. You may want to disable this behavior. (memcached option -L) * extra-options | string memcached has many other options documented in its man page. You may pass them here as a string which * factor | float Default: 1.25 Use as the multiplier for computing the sizes of memory chunks that items are stored in. A lower value may result in less wasted memory depending on the total amount of memory available and the distribution of item sizes. The default is 1.25. * listen\_address | string Default: 0.0.0.0 Listen on ; default to INADDR\_ANY. You may specify multiple addresses separated by comma. Binding to an internal or firewalled network interface is suggested. * min-item-size | int Default: -1 Allocate a minimum of bytes for the item key, value, and flags. The default is 48. If you have a lot of small keys and values, you can get a significant memory efficiency gain with a lower value. If you use a high chunk growth factor (-f option), on the other hand, you may want to increase the size to allow a bigger percentage of your items to fit in the most densely packed (smallest) chunks. (memcached option -n) * nagios\_context | string Default: juju Used by the nrpe-external-master subordinate charm. A string that will be prepended to instance name to set the host name in nagios. So for instance the hostname would be something like: juju-memcached-0 If you're running multiple environments with the same services in them this allows you to differentiate between them. * repcached | boolean Enable memcached replication * repcached\_origin | string Default: ppa:niedbalski/memcached-repcached Memcached + Repcached package location * repcached\_port | string Default: 11212 TCP port number for replication (default: 11212) * request-limit | int Default: -1 limit of requests a single client can make at one time (memcached option -R) -1 takes memcached default (20) * size | int Default: 768 Size of memcache pool in MiB (memcached option -m) * slab-page-size | int Default: -1 Override the size of each slab page in bytes. In mundane words, it adjusts the maximum item size that memcached will accept. You can use the suffixes K and M to specify the size as well, so use 2000000 or 2000K or 2M if you want a maximum size of 2 MB per object. It is not recommended to raise this limit above 1 MB due just to performance reasons. The default value is 1 MB. (memcached option -I) -1 takes the memcached default. * tcp-port | int Default: 11211 TCP port to listen on. (memcached option -p) * threads | int Default: -1 number of threads to use. default is 4. (memcached option -t) * udp-port | int UDP port to listen on (memcached option -U)
