Is there a C# implementation of Redis-rdb-tools?


Taking a look at Redis-RDB-Tools, it looks like there are some useful functions for monitoring the health of your Redis server.

ServiceStack.Redis seems to have a good set of client functions (but I'm using BookSleeve).

Are there any C# implementations that give me some basic health checks - consumed memory, disk usage, etc?

-- UPDATE --

Thanks to BookSleeve's GetInfo() command, the following is returned... however I should have been more specific: Is there a way of getting back the server info as parameters/object properties or a pre-packaged way of parsing the output values?

Here is the output from GetInfo():

Solution

  • With regards to the updated question: the information there is not currently exposed as "parsed", but that sounds like a reasonable thing to add; I suspect I'll hide the GetInfo() method, move it to .Server.GetInfo(), and expose it in a parsed form. The code to split it already exists, though - but as a private method: RedisConnectionBase.ParseInfo:

    static Dictionary<string, string> ParseInfo(string result)
    {
        string[] lines = result.Split(new[] { "\r\n" }, StringSplitOptions.RemoveEmptyEntries);
        var data = new Dictionary<string, string>();
        for (int i = 0; i < lines.Length; i++)
        {
            string line = lines[i];
            if (string.IsNullOrEmpty(line) || line[0] == '#') continue; // 2.6+ can have empty lines, and comment lines
            int idx = line.IndexOf(':');
            if (idx > 0) // double check this line looks about right
            {
                data.Add(line.Substring(0, idx), line.Substring(idx + 1));
            }
        }
        return data;
    }
