Question

下午好。

我正在尝试使用memcached插件，当我使用“munin-run”命令测试它时，我遇到了错误。

返回的错误是：

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.

memcached_hits插件的第28行和第29行，请参阅下面的相应代码：

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

我很难找到解决方案。亲切的，有人能帮助我吗？

谢谢。

确保您的memcached配置文件可能位于此处：

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

看起来像这样：

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

某些默认配置文件包含env行的额外信息，如下所示：

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