Maximum number of queued connections per second

Maximum number of throttled connections per second

Connection string in the URI format (password is not used). This param overwrites a value configured in the "Plugins.Memcached.Uri" option of the configuration file (if it's set), otherwise, the plugin's default value is used: "tcp://localhost:11211"

"An eviction is when an item that still has time to live is removed from the cache because a brand new item needs to be allocated.

The item is selected with a pseudo-LRU mechanism.

A high number of evictions coupled with a low hit rate means your application is setting a large number of keys that are never used again."

Manual close: YES

Zabbix has not received data for items for the last 30 minutes

Manual close: YES

Depends on:

- Memcached: Service is down

The max number of connections is reachedand and a new connection had to wait in the queue as a result.

Number of times a client connection was throttled is too hight.

When sending GETs in batch mode and the connection contains too many requests (limited by -R parameter) the connection might be throttled to prevent starvation.

When the number of connections reaches the value of the "max_connections" parameter, new connections will be rejected.

Memcached version has changed. Ack to close.

Manual close: YES

Uptime is less than 10 minutes
