Adding Custom Monitors 

Introduction

This section is common to all the editions of IT360 - Professional Edition, Enterprise Edition (Probes only) and MSP Edition (Probes only).

In addition to IT360's default monitors (for devices), you can also create your own monitors for the SNMP-enabled devices in your network. The SNMP variable, for which you intend to configure a monitor, can return either a numeric or string output, when queried.

To add a custom monitor for a resource of a particular device type, the device template must be modified. The new monitor should be defined in the device template, so that the monitor is associated for all the devices of that type.

The following topics are discussed here:

  1. Adding a custom monitor
  2. Viewing devices & custom monitors
  3. An example for adding a custom monitor
  4. Video on how to add a custom monitor

1. Steps to add a custom monitor

The below listed are the steps required for adding custom monitors:

  1. Login to IT360 console with the Username and Password of an Admin user.

  2. Click the Admin tab in the header pane.

  3. Click Template Library under Discovery.

  4. By default, the Device Templates tab will be selected. In the Device Templates wizard displayed, do the following:

  5. From the templates table, click the template Name link, for which you want to add new monitor(s). You can use the alphabet links to display templates starting with the desired letter.

  1. The Modify Device Template wizard is displayed, as shown below. Scroll down and click Add Monitors under the Monitors column.

  1. The Add Monitors window pops up. From here, you can either choose the existing monitors or add new. To choose existing, select the required checkboxes and click OK. Else, if you wish to add new monitors, do it in any of the below ways:

4.1 Add Individual Monitors:

    1. In the Add Monitors window that pops up, click 'New Monitor -> SNMP'.

  1. The Add New Monitor window pops up. Click the Select button to browse and select the OID, for which you want to add the monitor.

  1. The MibBrowser is shown as below. Select the required MIB followed by the OID. Click OK.

  1. In the Add New Monitor window, configure rest of the properties, such as Name, Displayname, Units, etc. Click OK. The new custom monitor is listed under Monitors column in the Modify Device Template wizard. Click Apply.

4.2 Add Bulk Monitors:

    1. You can add bulk monitors for proactive monitoring. In the Add Monitors window, click Add Bulk. The below wizard is displayed. Fill in the following information.

    1. Monitor Name: Provide a name for the monitor.

    2. SNMP OID: Enter the SNMP OID for the monitor.

    3. Numeric: Select this option if the entered SNMP OID returns numeric value.

    4. Tabular: If you require SNMP OID to return output in tabular form, then select this checkbox. In case of scalar SNMP OID,

    5. make sure to append .0 (dot followed by zero) at the end of object ID.

    6. Interval: Configure the polling interval for the monitor.

    7. Units: Configure the units for the monitor.

    8. Threshold Settings: Configure the threshold values based on severity and select the match condition.

    9. Rearm Value: Provide the value at which the alarm has to be cleared.

    10. Consecutive Times: Specify the number of times the threshold can be violated before raising an alarm.

    11. Click OK to add bulk monitors.

Now, the custom monitor is added to the template.

2. Viewing Devices & Custom Monitors Added under the Device Template

  1. Login to IT360 console with the Username and Password of an Admin user.

  2. Click the Admin tab in the header pane.

  3. Click Template Library under Discovery.

  4. The Device Templates wizard is displayed.

  5. In the Device templates table, the number of devices will be listed under the Devices column agianst the Device Template Name, as shown below:

  1. Now, click the number link under Devices. The Devices - Results will be displayed, as shown below. Click the Device Name link.

  1. It takes you to the snapshot page of that device, where you will find the added custom monitors under Performance Monitors, as shown below:

Note:

  • For SNMP-based monitors to work, make sure to enable SNMP on the devices, and check if the OID is implemented.

  • To easily apply a new monitor to a set of devices, you must add the monitor to the device template.

3. Example

Consider the example given below to add a Custom Monitor that monitors a SNMP variable, which returns a sring output when queried.

  1. Go to the Modify Device Template of Lucent.

  2. Click Add Monitors under the Monitors column.

  4. Click the 'Select button to open the MIB browser.

    1. Select 'RFC 1213 MIB' and click on 'Expand All'.

    2. Choose the 'System Name' variable. The OID of the same will be displayed at the bottom. [This variable will give the System Name of the device, when queried].

    3. Click on 'OK'. The OID will be displayed in the SNMP OID field.

  5. Configure all the other properties of the monitor, such as the Name, Displayname, Units, etc. Click OK. The new custom monitor is listed under Monitors column in the template.

  6. Click on Apply, to add the template to the devices.

  7. The devices are listed, prompting you to select the devices, for which you want the monitor to be associated. Check the list of devices and click Apply. The monitor will be associated to the selected devices under performance monitors.

Note: Before creating the custom monitors, get the necessary mibs from the vendor and place it under the directory '/IT360-Home/Network/mibs'.
