ejabberd：即使使用调试日志级别 (5)，记录到 /var/log/ejabberd/ejabberd.log 也不完整

Question

我有ejabberd 15.09来自测试运行于Debian 8.2 “杰西”（稳定的） 服务器。

由于从 ejabberd 升级稳定的/var/log/ejabberd/ejabberd.log 的日志记录似乎已损坏。即使loglevel设置为5(debug)，也不会记录用户活动。

这是我的/etc/ejabberd/ejabberd.yml：

设置完loglevel之后4我得到的全部内容/var/log/ejabberd/ejabberd.log是：

是否有任何隐藏的依赖关系需要满足（某些erlang-*包）才能恢复日志记录工作？我还可以检查什么？

Answer 1

好吧，我的怀疑是正确的，一些erlang软件包应该升级到测试存储库。我已升级所有已安装的erlang-*软件包，日志记录开始工作。不确定哪一个负责日志记录，但我相信升级它们全部本质上是一个好主意。这是命令：

sudo apt-get install -t testing erlang-p1-stringprep erlang-p1-yaml erlang-p1-pgsql erlang-p1-iconv erlang-p1-stun erlang-proper erlang-p1-utils erlang-p1-cache-tab erlang-p1-mysql erlang-goldrush erlang-p1-sip erlang-p1-xml erlang-jiffy erlang-p1-zlib erlang-lager erlang-xmlrpc erlang-p1-pam
