There are several ways to create a hosts file. The simplest option is to use a text editor to create the file, and then type the required entries. If you have a large number of systems to add, you can copy and paste each entry, and simply modify the appropriate fields. The sample host file attached to this article contains example entries that you can use as a template for your host file.
If you have a list of all your systems in a spreadsheet, you can save the list as a text file or a comma separated values (.csv) file, and then write a script to manipulate the text or .csv file into the proper format.
...
The following table describes the fields used in the hosts file. The fields required to add a system will vary depending on the type of system being added. For example, to add an agent system, you only need to include the Host Name, Type, and Port fields (see see Managing Your Infrastructureyour infrastructure for more information). An
The following table is an example of a properly-formatted hosts file is attached to this article (see below).

, which acts like a user ID or password |
, that gives you access to the system. Valid options are:
|
|
|
| Username |
If you are adding a Net-SNMP or Novell NRM system to Uptime Infrastructure Monitor, specify the user name required to access the system.

If you are adding a Net-SNMP or Novell NRM system to Uptime Infrastructure Monitor, specify the password required to access the
\nsystem.
| Group |
The name of the entity group (a set of systems that have been combined in a meaningful way) to which you want to add this system (optional field).
SSL
For agent systems, use this field to specify if Uptime Infrastructure Monitor will securely communicate with an agent installed on the system using SSL. Valid options are true and false (optional field).
Authenticatio n Method
For Net-SNMP systems, use this field to determine how encrypted information traveling between the Net-SNMP \ninstance and Uptime Infrastructure Monitor will be authenticated. Valid options are:
MD5 (a widely-used method for creating digital signatures). SHA (a secure method of creating digital signatures).
Privacy Password
For Net-SNMP systems, the password that will be used to encrypt information traveling between the Net-SNMP \ninstance and Uptime Infrastructure Monitor.
Privacy Type
For Net-SNMP systems, how information traveling between Uptime Infrastructure Monitor and the Net-SNMP instance \nis encrypted. Valid options are:
DES (an older method used to encrypt information).
AES (the successor to DES, which is used with a variety of software including SSL servers).
Pingable
For virtual nodes, use this field to specify if Uptime Infrastructure Monitor can contact the virtual node using the icmp ping utility. Valid options are true and false.
Adding multiple systems to UIM
To add multiple systems to Uptime Infrastructure Monitor with the addsystem utility:
- Copy the hosts file to the scripts folder in the directory where you installed the Uptime Infrastructure Monitor monitoring station. \n For example, if you installed the monitoring station in the default location, copy the hosts \nfile to the following folder:
Windows Installation: C:/Program Files/uptime software/uptime/scripts Linux Installation: /usr/local/uptime/scripts/
- At the command line, navigate to the scripts folder.
- Enter the following command:
