•  Type in the following information:

• Alias: Type a unique name to keep track of which groups you create in the SNMP Group Name field.
Note: Your naming convention relates to the specific device you are monitoring.
• Host: Type the IP address of the device in the host field. The number convention should be used, example: 10.0.0.45.
• Community: It will most often be "public" but unique needs may require another type of community to be specified.
• Connection Timeout (sec): Type a number in the Connection Time-out (seconds) field. This is how long the test should last
    before it stops and is considered inactive.
• Profile: Select a profile from the drop list.
Note: If you want the monitoring to run 24 hours a day, seven days a week (at the specified check frequency), do not select a profile.
• Check Frequency: Type the number for how often you wish the SNMP Objects within this group checked in the Check Frequency (Minutes) field.
• Description: Enter detailed description about the SNMP group to help other users understand the purpose of the group.
• Click the Add button to complete or the Reset button to clear the fields and input new data.

  Active Alerts

      Alert levels in SNMPWatch are denoted by the border color of the icons in the tree view. The icons are to the left of the system and OID names.

Color Codes
      •  Green - no alert
      •  Blue - informational alert status
      •  Yellow - warning alert status
      •  Red - error alert status
      •  Gray - monitoring is paused or the watch object has not yet been tested since its creation

The Relationship between Levels and Color Coding
System level in the tree view takes the most urgent color of the OIDs below it. For example,
even if only one OID of a system is in Error status, the border of that system will be colored red.

Managing the System Level
The System Level dictates the name of the system, its address, profile, check frequency, etc.

System Level Menu
Clicking the icon to the left of a system name brings up a menu with the following items:

•  Pause Monitoring to pause monitoring of all the OIDs in the system
•  Edit System to edit system attributes
•  Del. System to delete the system, you will be asked to confirm the deletion
•  Add OID to add SNMP Objects you want to monitor in this system
•  Use as Template to use the current settings for community name, connection timeouts, profile, and check frequency, and applies it to any of the user-defined hosts of choice.

Compare Selected
 This tool allows users to select metrics gathered from the same system or from different systems in order to compare the results.

                       

 • Click on the system folder icon to the left of the System name, and then check the radio button of interest.

 • Click on the same system and select another object to compare with the first selection, or select another system with the same object to compare.  Users can select any number of objects to be compared.

 • Once the user has made the selections, click on the system tools and select the compare selected button.

 • A graph will appear on the right-pane that with the results.

Edit a System

     

• Edit the system parameters as needed.

Note:  If you edit Check Frequency, the new check frequency will begin after the next originally scheduled check. For example, if it was originally a 15-minute frequency, it will check at 6:15 and 6:30. If you change the frequency to 5 minutes at 6:16, you will not see the 5-minute frequency begin until 6:30.

• Click the Update button.

 Delete a System

   • Click on the folder icon to the left of the System name, a menu will appear. Click Delete System button.  • A warning message pops up.  Click OK to confirm, or click Cancel to abort.

  Pause System Monitoring

• Click on the folder icon to the left of the System name, a menu will appear. Click Pause Monitoring button.

• Click OK to confirm your action.  

Resume System Monitoring

  Note: The resume monitor icon only appears when the system is in a paused state.

  • Click on the folder icon to the left of the System name, a menu will appear. Click Resume Monitoring.

Managing SNMP Instances

     Note: An SNMP Instance can only belong to one SNMP System. Keep in mind that the SNMP Object ID defines the information gathered and
              the unit of measurement.

Add/Create an SNMP Instance  

 • On the left-pane, click on the icon to the left of the System name, a menu will appear. Click Add OID.

  • Enter a name for the object in the Object Name field. Use a unique name such as the actual device name followed by
       the type of information being gathered. Example: "Router2_uptime".  

Note: The threshold values, data conversion and all aspects of a specific SNMP Object are integrated with the Object ID (OID).
The OID dictates what kind of information will be monitored. 
For example, a switch could have its uptime monitored, its downtime monitored and its description monitored but they would each
need a separate SNMP Object ID (and therefore three separate SNMP Objects created under the same SNMP Group).

Users may also choose to use our built-in MIB Browser. 
• Click on the  Launch MIB Browser icon to upload a specific MIB file to the Chroniker system. 

• A window pops up giving the user the option to

(1)   use an existing MIB(management information base) file on the left-pane, OR

(2)   upload an MIB file obtained from product vendors on the right-pane

Note: The Optional MIB File section allows users to upload dependent MIB files that work only in conjunction with base MIB files.

• If the user chooses to upload an MIB file, click on the Browse button and specify the location of the MIB file.  Do the same for the Optional MIB file. 
Once uploaded, the MIB file will become a choice on the Select a MIB File drop-down menu on the left-pane.

• Click on Submit to upload the file or Reset to start over.

• From the left-pane’s pull-down menu, choose the correct MIB file from the drop-down menu and drill-down to find the specific
  Object Identifier (OID) you want to monitor. 

• Once users select the OID, the right-pane window changes to allow users to test the OID using the SNMP Get button, or to
  Select this OID to be monitored.

 • Once you’ve selected the appropriate OID, you will be sent back to the Add New SNMP Object window.

For example, users can type in the equation on data returned such as *1024 to multiple the value by 1024.  In other cases, users may want to use /60 to divide the value by 60.

• Select the Data Conversion from the drop down list, this is an optional field. This option allows users to take the native format of the collected data and convert it into a more appropriate format.

Note: Certain types of information have different units of measurement. For example, some network switches have their time monitored in seconds, while other network devices are monitored in minutes. Another example is the difference of some devices being bytes while another is in kilobytes.

  • Select "Other" if you do not see the conversion you need from the drop list. Just enter your custom data conversion formula.
For example, users can type in the equation *1024 to multiply the native value returned by 1024.  In other cases, users may want to use /60 to divide the value by 60.

 • The Other field, an optional field provides a way for users to create custom formulas to convert data into different formats.

• Select a Unit of Measure from its drop down list. This option allows users to specify the unit of measurement that you want to
    see on reports or SNMP object listings.

       Response time (ms)
       True/False (Boolean)
       Number of Success (nb)
       Number of Failures (nb)
       Unknown
       Number
       Timetick = 1/100 seconds since some epoch
       Hour = 60 minutes
       Minute = 60 seconds
       Seconds
       Byte = 8 bits
       Bit = 1
       Megabyte (MB) = 1 million bytes
       Kilobyte (Kb) = 1000 bytes
       Gigabyte (Gb) = 1 billion bytes
       Percentage (%)
       Packets (pkts 

• Select an event from the drop list for each event type: Down, Error, Warning, and Information. Events you have defined, on the SNMPwatch Events page, are listed in the drop box.

 • Click the Add button at the bottom of the page or Click the Reset button to clear fields.

Edit an SNMP Instance

 • From the SNMPWatch home page, click on the icon to the left of the SNMP Instance Name, a menu will appear. Click Edit Instance.   

 • Edit the fields with new information.

  • Click the Update button.  

Delete an SNMP Instance

Defining Alerts

 To setup alerts that will be triggered when an SNMP object does not respond or its response time exceeds a certain threshold, you need to:    

• Define a Reaction. Reactions are enacted when thresholds are exceeded.

In SNMPwatch Page, click on Reactions button in the top menu bar Click on "Add New Reaction" and select the type of reactions you want to define: email, custom, numerical page, restart, or SNMP trap. Fill out the form.
Click here to learn more about reactions.

• Define an Event that the reaction will be applied to. Events will launch your predefined reactions when conditions you define are met. You can assign up to 2 reactions per event.

In SNMPwatch module, click on the events button in the top menu bar.Click on "Add New Event" button and fill out the form.
Click here to learn more about events.

• Apply this event to your SNMP object(s):

In the event page, click on the “Apply Event” button which is the first button to the left of the event you want to apply. Select your SNMP object(s) from the list. Click “Apply”

 Note: You can also apply a predefined event to an SNMP object by clicking on the edit button next to the SNMP object in the SNMP page.

For a detailed help on setting up reactions and events, please refer to Chapter 2: Features Common to All Modules .

Graph with SNMPwatch

SNMP Graph Restrictions  

The Graphs of SNMP Monitors can only be performed on Objects that have a numerical value over time. Comparison graphs can only
 be made of SNMP Objects that share the same unit of measurement.

SNMP Object groups, as a whole, cannot be graphed.

 Accessing SNMP Graphs     

Graphs in SNMPWatch are displayed on the SNMPWatch home page (there is no separate graphs page in SNMPWatch).

You can display graphs in two ways:

  (1) Click on the SNMP Instance Name found under the System Name in the left pane
  (2) Click in the check boxes next to SNMP Instance Name of multiple OIDs and then click Compare Selected so see multiple results  
         in a single view

 Summary Data for SNMPwatch      

SNMP Summary data is displayed in a box to the bottom of any graph. Summary data listed includes: SNMP System and Instance, Check Frequency, Last Checked At [time], Next Check Scheduled At [time].
