我正在尝试构建collectd系统性​​能监控包（版本5.4.1；在Fedora v20 VM上构建collectd）并想使用write_mongodb插件。

我./configure在文件夹 collectd-5.4.1 中运行，在那里我下载了包源文件，但由于以下错误而无法获得 write_mongodb 支持（如 collectd 文件夹的 config.log 文件中所示）：

/home/user01/Documents/libs/collectd-5.4.1/conftest.c:181: undefined reference to 'mongo_run_command'

我正在尝试链接到我之前编译生成 libmongoc-1.0.so.0.0.0（版本 0.96.4）的 mongo-c-driver 库。

我在脚本中进行了以下修改configure以链接到 libmongoc：

LIBMONGOC_CPPFLAGS="$LIBMONGOC_CPPFLAGS -I/usr/local/include/libmongoc-1.0/ -I/usr/local/include/libbson-1.0/" 
LIBMONGOC_LDFLAGS="$LIBMONGOC_LDFLAGS -L/usr/local/lib/ -L/usr/local/lib/"

并将文件复制到文件mongoc.h夹中/usr/local/include/libmongoc-1.0/mongo.h

config.log以下是collectd 文件夹中配置脚本输出的片段，其中包含与mongo_run_command.

我没有mongo_run_command在文件夹 mongo-c-driver-0.96.4 的文件中的任何地方找到该函数

mongo-c-driver-0.96.4/src/mongoc/.*
mongo-c-driver-0.96.4/src/libmongoc.symbols

谢谢。

以下步骤修复了在为 collectd 系统性能监控包构建写入 MongoDB 插件支持时遇到的问题。

编译 Mongo-C-Driver 和 Collectd

需要以下步骤和代码更新来构建和使用 collectd 中的 write_mongodb 插件将系统性能数据直接发送到 MongoDB 数据库。

  • 下载 collectd-5.4.1 到，比如说，

    • COLLECTD_DIR=/home/user01/libs/collectd-5.4.1

    不要编译/构建collectd，但是。

  • 从 GitHub 下载 mongo-c-driver 版本 0.8.1。最新版本的mongo-c-driver与collectd 5.4.1版本不兼容

  • 将 Mongo 0.8.1 构建到文件夹： MONGOC_DIR=/home/user01/libs/mongo-c-driver-0.8.1

  • 将库 libbson.so 和 libmongoc.so 从 MONGOC_DIR 复制到/usr/local/lib和/usr/local/lib64

  • 将 libmongoc.so 库复制到以下位置： sudo cp /usr/local/lib/libmongoc.so /lib64/libmongoc.so.0.8 sudo cp /usr/local/lib/libmongoc.so /lib/libmongoc.so.0.8

  • 将.h头文件从文件夹复制MONGOC_DIR/src到/usr/local/include

  • 转到 COLLECTD_DIR 并对配置脚本进行以下更改

    // Comment the lines with -I$withval/include and -I$withval/lib and replace them with following // Before > LIBMONGOC_CPPFLAGS="$LIBMONGOC_CPPFLAGS -I$withval/include" LIBMONGOC_LDFLAGS="$LIBMONGOC_LDFLAGS -L$withval/lib" // After > LIBMONGOC_CPPFLAGS="$LIBMONGOC_CPPFLAGS -I/usr/local/include/" LIBMONGOC_LDFLAGS="$LIBMONGOC_LDFLAGS -L/usr/local/lib/"

  • 运行脚本./configure

  • 对文件 COLLECTD_DIR/src/write_mongodb.c 进行以下更改；在这个问题中提到了这些变化。
    • 更改bson_create为bson_alloc
    • 更改bson_dispose为bson_dealloc
  • 编译collectd：运行sudo make clean然后sudo make重新编译collectd。
  • 通过运行收集的安装sudo make install

使用 MongoDB 运行 Collectd 和测试

  • 启动 MongoDB 服务器
  • 运行收集：/opt/collectd/sbin/collectd
  • 启动mongo服务器
  • 在 mongo 会话中运行以下命令以检查与 collectd 的连接 show dbs use collectd db.getCollectionNames() db.load.find().sort({x:1}).limit(3).pretty()
