1.2.3 Checking the prerequisites of the Monitoring Manager (for Linux)

If the Monitoring Manager is to run on Linux, check the settings below, and then start installing the JP1 network management products.

Procedure

1. Check the host name of the Monitoring Manager.

   The host name is used for setting the trap destination and during login.

2. Make sure that the port number to be used by the Monitoring Manager is not used.

   If you execute netstat -an at the command prompt, you can check the currently used port numbers.

   For details about the port numbers, see the topic List of Ports Used by NNMi in the JP1/Network Node Manager i Setup Guide.

3. Assign a static IP address to the Monitoring Manager.

   You need to assign a static IP address, not a dynamic IP address by DHCP.

4. Disable the antivirus software.

   Disable the antivirus software only during the installation of the JP1 network management products.

5. Make sure that the following packages and library files are installed:

   • kernel-2.6.32-220.4.2.el6.x86_64.rpm or later

   • kernel-firmware-2.6.32-220.4.2.el6.noarch.rpm or later

   • /lib64/libaio.so.1

   • /usr/lib64/libXtst.so.6

   • /usr/lib64/libXi.so.6

   • glibc (i686)

   • libstdc++ (i686)

   • libgcc (i686)

   • ncompress (x86_64)

   • tar (x86_64)

   • gdb (x86_64)

   • openmotif (x86_64)

   • glibc (x86_64)

   • glibc-common (x86_64)

   • glibc-devel (i686)

   • glibc-devel (x86_64)

   • glibc-headers (x86_64)

   • glibc-utils (x86_64)

   • nscd (x86_64)

   • libXtst (i686)

   • libnsl (Linux 8.1 or later, CentOS 8.1 or later, Oracle Linux 8.1 or later)

   • lsb_release

   • net-tools

   • unzip

   • fontconfig

   • liberation-sans-fonts (It is not necessary if fc-list command shows one or more fonts.)

   In addition, install the library files that depend on each of the files above. The required packages and library files differ depending on the type or version of the OS. For details, see the Release Notes.

6. Open the /etc/sysctl.conf file, and set the kernel parameters.

   Add the following entries to the /etc/sysctl.conf file:

   # NNM settings for embedded database
   kernel.shmmax = 68719476736
   kernel.shmall = 68719476736
   # NNM settings for UDP receive and send buffer sizes
   net.core.rmem_max = 8388608
   net.core.wmem_max = 2097152

   In the entries above, the shared memory (kernel.shmmax, kernel.shmall) is set to 64.0 GB, the UDP receive buffer (net.core.rmem_max) is set to 8.0 MB, and the UDP send buffer (net.core.wmem_max) is set to 2.0 MB.
