1 Navigator: Introduction and Interface 1-1 Introducing Navigator Navigator enables you to analyze critical system performance information on a microscopic level, in real-time mode. It monitors CPU usage, applications, processes and devices. You can request information about specific areas, and then view the results in tabular format on Web pages. Data entries in the table can appear as hyperlinks to more detailed information, which is then displayed on another Web page.
1-2 Navigation Menu The menu displayed on the left side of the Navigator window provides access to various Navigator functionalities. The various options available are: • Dashboard Dashboards display multiple views in a single window. Each dashboard contains a set of views and reports that you can manage as a single unit. Dashboards simultaneously display the individual elements. Alternatively, dashboards display views one at a time in an automatic cycle.
Icons & Hyperlinks The following table explains the targeted area of graphics in the Navigator window. Category General Icon Description Home page of the Navigator and all entities of the system.

2 Working with Navigator 2-1 Prerequisites Before running OVNPM Navigator, ensure that the following tasks have been accomplished: 1. 2. Any Web browser that is compliant with HTTP 1.0, HTML 3.2, JavaScript 1.2, Netscape 4.7 and Microsoft IE 4.0 and higher versions are available. OVNPM Server environment is installed and running on the HP Nonstop Server. For details, refer to the OVNPM Server Guide. 3. The Navigator port should be available outside the firewall on the HP NonStop Managed Host.
Step B: Logging On When you connect to Navigator you must provide a valid logon and password. Opening the Navigator window displays the Connect to dialog box. Figure 2-1 Enter Network Password Dialog Box Associated with each logon is a profile, which determines the information a user can view. The ADMIN logon has special privileges, and can determine the profiles and passwords of other users. Enter the User Name and Password in the dialog box and click on the OK button.
2-3 Dashboard Dashboards display multiple views in a single window. Each dashboard contains a set of views and reports that you can manage as a single unit. Dashboards simultaneously display the individual elements. Alternatively, dashboards display views one at a time in an automatic cycle. To access the Dashboard information, click on the Dashboard link. This displays the corresponding page. Click on the Top Dashboard link to access the Top dashboard page.
The following example shows selecting both cpu and disc domains for a NonStop Server. Only objects with cpu busy %>=0.1 sec ( 100 msec) are displayed. Figure 2-3 Navigator Top Dashboard Results Dashboards display multiple views in a single window. Each dashboard contains a set of views and reports that you can manage as a single unit. Dashboards simultaneously display the individual elements. Alternatively, dashboards display views one at a time in an automatic cycle.
Disk Metrics Metric Description cpu busy % Percentage of CPU time used by the Disk Processes for the current disk. io busy % Percentage of time that the disc was being used during the sample time. io kbits/s Total number of kilobits written and read during the sampling period. free GB Gigabytes of disc space available on the specified disc. frag # Number of individual free space fragments on the disk. lrgst MB Megabytes of the largest free space fragment on the disk.
AppliDef Metrics Metric Description cpu busy % Percentage of time that the APPLIDEF processes were executing in the CPU. This metric may have a value between 0% and (#cpu * 100%) io kbits/s Number of kilobits per second handled by these APPLIDEF processes during the sample period. This includes sent-bits and returned-bits, as well as received-bits and reply-bits. msg sent Number of messages sent by the APPLIDEF processes to other processes.
