Kernel parameters

Before installing the Analyzer server on Linux, you must set the following kernel parameter values:

File* Parameter Value to be set

/etc/sysctl.conf

Fourth parameter (SEMMNI) of kernel.sem

The larger of 1024 and the following value: 24 + current-system-value

/etc/security/limits.conf

soft nofile

hard nofile

The larger of 8514 and the following value: 4418 + current-system-value

* The file path differs according to the environment. In addition, kernel parameters can also be set for files that are not listed here.

Hardware requirements

To complete the installation, a minimum of 2 GB.

If the Common component is already installed, you need at least 2 GB of free space in the directory where the Common component is installed.
  1. Do not create these directories on a Network File System (NFS) partition.
  2. The Analyzer server retrieves the partition details and checks the free disk space. If any of the listed directories are located on the same partition, the required disk space is the sum of the disk space of the directories.
  3. If Analyzer server and Analyzer detail view server are installed on the same host, use these values:

    Small: 7, Medium: 8, Large: 8

  4. To monitor hypervisors or switches in addition to storage systems, you must increase the number of resources based on the system scale.
  5. If you want to monitor both hypervisors and switches, just use the larger of the two resource requirements.
  6. For details about the default installation directory, see Default installation directory.
  7. Do not include any symbolic links in the installation directory.
