我想在我的 varnishncsa 日志中包含以下信息（我需要将一些问题与特定用户联系起来）。

• 帖子请求的内容
• 包含完整内容的 cookie
• XID

阅读https://www.varnish-cache.org/docs/trunk/reference/varnishncsa.html后，我不太确定如何实现它。

顺便说一句，我无法将“varnishncsa”标签添加到问题中 - 有人可以添加它（具有更高的声誉？：P）。

我有使用 pnp4nagios 的 nagios 基础设施。最后几天我添加了新的主机 nosql 和安装在那里的 mongodb 警报。

主机配置：

define host{
        host_name               nosql
        use                     linux-server,host-pnp
        address                 xxx.xxx.xx.xxx
        }

服务配置：

define service{
        hostgroup_name                  nosql-servers
        use                             generic-service,pnp-service
        service_description             MongoDB Connect
        check_command                   check_nrpe!check_mongo_connect
        }

它们的配置方式似乎与其他配置方式相同。但是，当我尝试访问 pnp4nagios 中的图形时，我得到：

Please check the documentation for information about the following error.

XML file "/usr/local/pnp4nagios/var/perfdata/nosql/MongoDB_Connect.xml" not found. Read FAQ online

file [line]:
application/models/data.php [312]:

我有点帮助。

我应该如何激活新图表？

今天我注意到我的 LDAP 服务器 (OpenDS) 在每个可用内核上都占用了 100% 的 CPU。快速诊断显示在 futex 锁定期间有很多 ETIMEDOUT。

我如何调试它以弄清楚发生了什么以及如何修复它？

不确定它是否相关 - 但我还注意到 Redmine（Ruby 应用程序）具有类似的“功能”......帮助:)

我正在使用 pnp4nagios 和 nagios。

一切似乎都已正确集成 - 我在每个链接到 pnp4nagios 图形的主机和服务附近都有“额外操作”图标。

但是，当我访问https://xxxx/pnp4nagios/时，它总是将 url 更改为：

https://x.x.x.x/pnp4nagios/graph?host=webhost01

我怎样才能关闭这种行为？

我想在 /pnp4nagios/ 上查看从所有服务器收集的图表。

我在我的 CentOS 5 机器上配置了几个存储库。作为效果，命令：

yum search nagios

输出一团糟——数千个重复的包。

例如，为了让我的生活更轻松，我想仅在特定的 repo 中搜索包nagios，例如 rpmforge 和最低版本“3”。

我怎样才能做到这一点？
