Memcached：插件Munin錯誤

Question

下午好。

我試圖使用memcached插件，當我使用命令「munin-run」來測試它們時出現錯誤。

返回的錯誤是：我有困難發現了一個解決方案

$ip =~ s/_/./g; 
my $address = "$ip:$port"; 

：

Use of uninitialized value $ip in substitution (s///) at /etc/munin/plugins/memcached_hits line 28. 
Use of uninitialized value $ip in concatenation (.) or string at /etc/munin/plugins/memcached_hits line 29. 
Use of uninitialized value $port in concatenation (.) or string at /etc/munin/plugins/memcached_hits line 29. 
Use of uninitialized value $ip in hash element at /usr/share/perl5/Cache/Memcached.pm line 253. 
Use of uninitialized value $ip in index at /usr/share/perl5/Cache/Memcached.pm line 279. 
Use of uninitialized value in subroutine entry at /usr/share/perl5/Cache/Memcached.pm line 288. 
Bad arg length for Socket::pack_sockaddr_in, length is 0, should be 4 at /usr/lib/perl/5.14/Socket.pm line 260. 

的線28和memcached_hits插件29，請參考下面的各個碼。有人能幫助我嗎？

謝謝。

讓這可能居住在這裏確認您的memcached配置文件：

/etc/munin/plugin-conf.d/memcached 

看起來是這樣的：

[memcached_*] 
env.host 127.0.0.1 
env.port 11211 
env.timescale 3 

一些默認的配置文件包含的ENV線這樣的額外的信息：

# BAD! DELETE *default* 
[memcached_*] 
env.host 127.0.0.1 *default* 
env.port 11211  *default* 
env.timescale 3  *default*
