Install

The damemtop script was already installed on my CentOS system (with memcached):
```
/usr/share/doc/memcached-1.4.5/damemtop
```
I had to install the following Perl dependencies (although not sure I needed to):
```
cpan AnyEvent Term::ReadKey YAML
```

Configuration

Set-up the configuration file:

vim /etc/damemtop.yaml

… with these contents (put the IP addresses for your own servers in the servers section):

delay: 3
mode: t
top_mode:
    sort_column: "hostname"
    sort_order: "asc"
    columns:
        - hostname
        - all_version
        - all_fill_rate
        - hit_rate
        - evictions
        - bytes_written
        - "2:get_hits"
servers:
    - 192.168.10.3:11211
    - 192.168.10.4:11211

Note: I don’t think this configuration will work with server names. Use the IP address.
