This article mainly introduces "the solution to the error in the use of Nagios under CentOS 6.3". In the daily operation, I believe that many people have doubts about the wrong solution to the problem of using Nagios under CentOS 6.3. the editor consulted all kinds of materials and sorted out the simple and easy-to-use operation method. I hope it will be helpful to answer the question of "wrong solution to the use of Nagios under CentOS 6.3"! Next, please follow the editor to study!

Have been using the following versions of Centos6.3, when the new server arrived, a relatively new Centos6.3 was installed, so there was a minor problem when using Nagios monitoring.

When monitoring the memory of the system, there was no problem with the previous monitoring script, but the normal monitoring data could not be obtained on the new server. Later, the following error was found when executing the relevant commands directly on the client side of Nagios:

/ usr/local/nagios/libexec/check_mem-w 2-c 1

/ usr/local/nagios/libexec/check_mem: line 78: / usr/bin/dc: there is no such file or directory.

What's going on without the dc command? A search on the Internet failed to solve the problem. * find some clues in an article and solve it!

The original dc command is a calculation-related command that comes with the system, but Centos6.3 is not installed by default, so how to install it? use yum install dc to report that there is no dc installation package.

* you can only Google once. It turns out that bc and dc are two progressive commands, and the dc command is included in the bc installation package, so you can yum install bc decisively. After completion, you will find that there is already a dc command!
