I am trying to build the collectd system performance monitoring package (version 5.4.1; building collectd on Fedora v20 VM) and want to use the write_mongodb plug-in.

I run ./configure in the folder collectd-5.4.1 where I have download the package source files but cannot get write_mongodb support due to the following error (as seen in config.log file of collectd folder):

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

I am trying to link to mongo-c-driver library, which I previously compiled to generate libmongoc-1.0.so.0.0.0 (version 0.96.4).

I made following modifications in the script configure to link to 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/"

and copied the file mongoc.h into the folder as /usr/local/include/libmongoc-1.0/mongo.h

Following is snippet from output of configure script config.log in collectd folder that has the error relating to mongo_run_command.

I did not find the function mongo_run_command anywhere in files in the folder mongo-c-driver-0.96.4

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

Thanks.

Following steps fixed problems encountered while building Write MongoDB plugin support for the collectd system performance monitoring package.

Compiling Mongo-C-Driver and Collectd

Following steps and code updates are needed to build and use the write_mongodb plugin in collectd to send system performance data directly to MongoDB database.

  • Download collectd-5.4.1 to, say,

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

    Don’t compile/build collectd, yet.

  • Download mongo-c-driver version 0.8.1 from GitHub. Latest version of mongo-c-driver is not compatible with the collectd version 5.4.1

  • Built Mongo 0.8.1 to the folder: MONGOC_DIR=/home/user01/libs/mongo-c-driver-0.8.1

  • Copy the libraries libbson.so and libmongoc.so from MONGOC_DIR to /usr/local/lib and /usr/local/lib64

  • Copy the libmongoc.so library to following locations: sudo cp /usr/local/lib/libmongoc.so /lib64/libmongoc.so.0.8 sudo cp /usr/local/lib/libmongoc.so /lib/libmongoc.so.0.8

  • Copy .h header files from folder MONGOC_DIR/src to /usr/local/include

  • Go to COLLECTD_DIR and make following changes to the configure script

    // 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/"

  • Run the script ./configure

  • Make following changes to file COLLECTD_DIR/src/write_mongodb.c; the changes are mentioned in this issue.
    • change bson_create to bson_alloc
    • change bson_dispose to bson_dealloc
  • Compile collectd: run sudo make clean and then sudo make to compile collectd afresh.
  • Install collected by running sudo make install

Running Collectd and Testing With MongoDB

  • Start MongoDB server
  • Run collected: /opt/collectd/sbin/collectd
  • Start mongo server
  • Run following commands in mongo session to check connection with collectd show dbs use collectd db.getCollectionNames() db.load.find().sort({x:1}).limit(3).pretty()
