If the device is new, the monitoring preset groups will be auto-discovered. If the device is a server, also the most important host processes will be detected and monitored.
In the next screen this may be changed and saved. Click on All presets to setup individual monitoring presets for this device.
A preset group is a group of monitoring presets. A monitoring preset is used to collect monitoring data, such as network traffic or CPU utilization.
Monitor Presets are used to measure all kinds of values, such as network traffic (IfOctets),
Errors, HTTP Get reponse times, SMTP status and more. Monitor Presets can be customized and added. Monitoring groups can be
created to group a logical set of hosts with monitored interfaces. Groups can be used in reporting, monitor status and realtime view.
Status Monitoring can be enabled to send SNMP traps if hosts do not respond. The Node Up/Down events will be stored
in the eventlog database. Using event actions, e-mail or SMS notification can be configured.
Select in the main menu the DEVICES function.
Then click on a host. The host will appear in a semi 19" rack device view. Click the button in the device view to view the realtime monitoring. A graph of all monitoring during last hours on that device will be plotted.
The screen will be refreshed every minute.
The monitor screen can be used to view graphs, configure monitoring presets and preset groups.
Select in the main menu the MONITOR function.
The monitor screen will display a preset group browser. Opening a preset group will show inidividual monitoring presets.
In the example below the preset group Host contains the monitoring presets Disks, HostCPU, IfErrors and IfOctets.
Opening a monitoring preset will show all devices that are monitored with that preset. Opening a device will show all
monitored objects, such as interfaces or disk partitions. Click on the button
to plot a graph. Click on the host link to edit graph settings and plot a graph.
Click on the icon to apply the preset to multiple hosts or edit the monitoring preset.
The monitor group view will display the status of monitoring presets combined in a group. These groups can be configured using the Edit button and used for reporting.
To view all monitoring presets, click on All.
The Status button will show the realtime status of a monitoring group using meters and bars.
Select in the main menu the MONITOR function.
The monitoring browser screen will be displayed.

Scientists are warning that Mount St. Helens could erupt sometime today, and with more force than previously expected. "There is a 50 percent chance or greater that there is going to be an eruption and a good chance that it will involve magma," said Tom Pierson of the U.S. Geological Survey. "We're watching very closely." On Friday the volcano spewed a harmless plume of steam and ash into the air, but it was still the biggest eruption by the volcano in 18 years.

Service response can also be used to monitor values from a web based application.
Example: application writes to HTML page. This page can be used as input for NINO.
Variable
Value
Web users:
122
CPU:
12.5 %
Cache:
876 MB
Select servcice web variables to edit the variables you want to monitor.
NINO will use a search string and capture the next word. So in this example the
variable / search string Web users: will have result: 122.
Click on the Save button to create a monitoring preset.
Using this feature NINO is able to log, create graphs and reports using web pages as input.
Example: The Apache server-status page can be monitored using Service response - web variables.
The interface information screen will show snmp counters. NINO will use a formula to convert
Octets/s into Bit/s in the monitoring graph or in realtime monitoring screens. How does it work ?
Every interval the snmp counters are read form a device. To get the monitoring data,
you'll need two counters and the time interval in seconds. These values are computed into a
Value/S. The Octet values are converted in Bit/s. Example:
Time
IN Octets counter
OUT Octets counter
t=0 seconds
3241004
2541164
t=10 seconds
3294511
2611541
The total IN octets in 10 seconds: 3294511 - 3241004 = 53507
The total OUT octets in 10 seconds: 2611541 - 2541164 = 70377
Total IN + OUT octets in 10 seconds: 53507 + 70377 = 123884
Formula: (Octet = 8 bit)
network traffic = ( 8 * Octets ) / (tend - tstart) in Bit/s
Total: (8 * 123884) / 10 = 99107 Bit/s
This formula needs to be entered in the preset configuration screen. The formula uses standard calculus notation as input and has some pre-defined functions.
The formula field may be left empty if no formula is used.
Counter32( host:port:snmp_oid ) : 32 bit counter function to calculate new value - old value
the host and port must be left empty if no specific host or port is defined
other than default.
duration : duration in seconds, new timestamp - old timestamp from logfile
* / + - ( ) : standard calculus symbols
Example IfOctets:
8 * (counter32(::.1.3.6.1.2.1.2.2.1.10) + counter32(::.1.3.6.1.2.1.2.2.1.16)) / duration
Click on menu MONITOR, browse a preset from the screen and click on the icon.
Click on the Configure preset link to edit the preset. Create a new preset by changing the preset name.
This example shows the network traffic IfOctets preset. The total network traffic needs to be calculated using formula below. The IfInOctets and IfOutOctets are added and a Bit to Byte conversion is calculated. Because IfInOctets and IfOutOctets are counter-values, the counter32 function is used to substract new value - old value.
This example shows the Load15 preset. The average system Load of the last 15 minutes is monitored with this preset.
The threshold levels are set to trigger alerts in the eventlog.
Select in the main menu the TOOLS function.
Click on the link Discover IP range. Fill in the start IP address and the end IP address
of the IP range. The alternative community string can be used for devices using another

Select in the main menu the TOOLS function.
Click on the link MIB Browser. The next browser screen will show all information of the loaded MIBs.
It is required to import MIB files first. MIB files are located in the docroot/mibs directory. The MIB information
is stored in the MySQL database. From the MIB browser it is easy to test SNMP queries and create monitoring presets.
Select a MIB to view information. Click on the OID to perform a SNMP walk. Apply will create a monitoring preset using
the MIB information.
The first step is to create a HTML template suited for your situation. The next step is to use inline script functions
to create graphs and event database info. The next step is to define monitoring groups, this is a group of hosts with monitored interfaces.
Such a group can be selected when creating a report, so only the monitoring results of that group are displayed in the graphs.
Select menu TEMPLATES and click on to edit a template.
Just enter HTML and copy - paste functions in the textarea. Use the Save button to save the template.
To use the template function, click on the template filename link. The template function can process templates on the fly
using the group Default. Becasue no day or month info is entered all data is used.
Select in the main menu the REPORT function.
This screen will appear. NINO will generate a HTML report of
the monitoring results and event database information. Default a network traffic report
is generated using the monitoring data. To customize your reports, please select HTML templates with inline scripting.
To make a report, select a template and define the startdate until enddate the report should be. All monitoring collect or trend data, database eventlog and userlog data from the startdate until the enddate will
be used. The monitoring data defined in the selected group are plotted in a graph (using graph width and height input in pixels).
Click on Edit to modify groups.
Go to menu ADMIN and click on FILEMGR to manage NINO files. The file manager enables you to view, download, upload and delete files.
This can be used to view and manage report files, view or delete raw monitoring data, upload your own alert sounds or upload images to create new device types.
