Fetching Memcached Stats Items in C# (Detailed Guide w/ Code Examples)

Use Case(s)

The stats items command is used with Memcached to fetch detailed statistics for each slab class. This can be useful when optimizing the memory usage of a Memcached server or troubleshooting an issue, as it provides insight into how different data sizes are being stored and accessed.

Code Examples

In C#, you can use the EnyimMemcached client to communicate with your Memcached server. Here's an example of how to fetch stats items:

// Initialize Memcached client configuration var config = new MemcachedClientConfiguration(); config.Servers.Add(new IPEndPoint(IPAddress.Loopback, 11211)); using (var client = new MemcachedClient(config)) { // Fetch stats items var stats = client.Stats(); foreach (var stat in stats) { Console.WriteLine($"{stat.Key}: {stat.Value}"); } }

In this example, we first configure our Memcached client to connect to a server at localhost on port 11211. Then we create a new MemcachedClient instance using this configuration. The Stats() function is used to retrieve all statistics available from the Memcached server. Each of these statistics is then outputted to the console.

Best Practices

  • Always close your connection: You should always ensure that your connections to the Memcached server are properly closed after use. In our examples, this is handled by using statement, which ensures that the client will be disposed of after use.

  • Handle exceptions: In production code, make sure to handle exceptions that might be thrown while communicating with the Memcached server.

Common Mistakes

  • Not validating server response: It's a common mistake to not validate the response from the Memcached server. Always validate your responses and handle exceptions where necessary.


Q: How can I fetch stats for a specific item? A: The stats items command fetches stats for all slab classes, not individual items. If you need to check the statistics of a specific item, you may use get or gets commands to retrieve the item and inspect it in your application.
