Collecting Installation Information

Collecting Installation Information

This section describes how to collect installation information covering the host name of the analyzer and collector, IP address, disk partition scheme, time and time zone, user name and password of the software, and installation path.


The installation planning of the eLog is complete. For details, see Deployment Planning.


To facilitate subsequent use and filing, you are advised to use the tables in the Task Example column to record installation information.


  1. Collect the host name of the analyzer and collector.
  2. Collect the IP address of the analyzer and collector.

    The principles for planning IP addresses are as follows:
    • The IP addresses must be unique on the network.
    • The eLog supports only IPv4 addresses.
    • The collector communicates with the managed log sources in normal state.
    • The analyzer communicates with the client in normal state.
    • The analyzer communicates with the collector in normal state.
    • Only one IP address can be planned for each network interface.

  3. Define the time and time zone of the physical location where the analyzer and collector resides.
  4. Collect the user names and passwords of the operating system of the analyzer and collector and those of the eLog software.
  5. Determine the principles and schemes for partitioning the server disk.

    The basic principles for disk partitioning are as follows:
    • The swap partition is used in system data transaction.
    • The root partition houses only the operating system.
    • The collector partition is used to install the collector and store logs.
    • The analyzer partition is used to install the analyzer.

  6. Plan an installation path.

    The installation path of the eLog software contains only letters, digits, and underscores (_). The value cannot contain any spaces, brackets, or Chinese characters. Otherwise, the installation fails.



Before you use the following table during the installation, delete information from the Plan column and print the table.

The user passwords are default ones. You can change the passwords as required.

Table 4-2 Analyzer installation information



Analyzer host name

  • The eLog server host name must be unique on the network.
  • A host name consists of letters (A to Z or a to z), digits, and hyphens (-), and its first character must be a letter.
  • Host names are case-sensitive.
  • Single-character host names are not allowed. That is, each host name must contain at least 2 characters.
