Memcached stats settings can be used in various scenarios including:
Here's an example of how to retrieve Memcached stats in Ruby using the dalli
gem:
require 'dalli' dc = Dalli::Client.new('localhost:11211') stats = dc.stats puts stats
In this code, the 'dalli' gem is used to connect to a Memcached server running on localhost port 11211. The stats
method is then called to retrieve the statistics, which are displayed using puts
.
Another example shows specific statistics like current items, get hits and misses:
require 'dalli' dc = Dalli::Client.new('localhost:11211') stats = dc.stats puts "Current items: #{stats['localhost:11211']['curr_items']}" puts "Get hits: #{stats['localhost:11211']['get_hits']}" puts "Get misses: #{stats['localhost:11211']['get_misses']}"
In this example, specific statistics are accessed from the stats hash and printed out.
stats
: Frequent calls to retrieve stats can impact the performance of your Memcached server. Use it judiciously for monitoring purposes.Not checking whether Memcached server is running: Before retrieving stats, always ensure that your Memcached server is running to avoid any connection failures.
Q: What does 'curr_items' in the stats mean? A: 'curr_items' refers to the current number of items stored by the server.
Q: What do 'get_hits' and 'get_misses' represent? A: 'get_hits' and 'get_misses' represent the number of successful and failed retrieval requests respectively.
