Object Types

The Object Types page enables you to manage the object types and the indicator types you want each plugin to poll. Object types enable a plugin to discover related objects on a device. Indicator types enable a plugin to collect data from the indicators on objects. SevOne NMS provides a starter set of object types and indicator types. SevOne NMS discovers devices and discovery manages the objects on the devices based on the plugins that are enabled for each device. Objects contain indicators that are polled to gather the measurement points of the physical and logical capabilities of a device.

To access the Object Types page from the navigation bar, click the Administration menu and select Monitoring Configuration, then Object Types.

In Object Types and Indicator Types, you can populate expressions in various fields. When variable(s) are evaluated using the S3 sytax, the content of the variable must not be a string OID. Rather, OID must be in numerical form. During Discovery, untranslated string OIDs do not return any results. However, OID literals in the string form are accepted. For details on S3 syntax, please refer to SNMP Quick Start Guide.

Object Types

Object types determine what objects are discovered on a device. Object discovery varies from plugin to plugin. You must enable object types for the JMX plugin and the WMI plugin on the Object Types page to discover JMX and WMI objects. You define objects for the Calculation plugin on the Calculation Editor. You define objects for the xStats plugin on the xStats Source Manager.

The Object Rules page enables you to define rules to disable, enable, or block discovery of objects and the Object Manager enables you to manage the objects on each device. The Cluster Manager > Cluster Settings tab enables you to disable polling of objects the SNMP plugin discovers to be operationally down or administratively down.

The Object Types list appears on the left and displays the object types for the filter you select above the list. Disabled object types are not discovered or polled and disabled objects do not count towards your license capacity. See the following sections for plugin specific object type management steps.

Filter - Click the Filter drop-down and select the plugin whose object types you want to manage. Please see the plugin specific sections below.
Add and - Click to display the plugin specific object type pop-up that enables you to add or edit the object type. Please see the plugin specific sections below.

- - Object type is enabled and the objects in the object type can be polled on devices for which you enable the plugin.
- - Object type is disabled and no metrics are collected.
- - Object type is enabled and required for the plugin. You cannot disable, edit, or delete the object type. This object type and its indicator types are polled when you enable the plugin for a device.

Indicator Types

Indicator types determine what indicators are polled for an object type. The indicator types list displays the indicator types for the object type you select in the Object Types list. Please see the plugin specific sections below. There are two types of indicator types.

Atomic indicator types are measured directly by the plugin.
Synthetic indicator types are indicators whose value is dependent upon other indicators; atomic and/or synthetic. Synthetic indicators enable you to combine the data from several indicators into one synthetic indicator so that SevOne NMS can properly evaluate indicators such as Percentage Loss, Percent Error, Percent Idle, and other high precision metrics.

The Indicator Types section provides controls to manage indicator types and displays the following information.

- Select the check box for each indicator type to manage, click , and select one of the following options.
- Select Delete to delete the indicator types and all associated indicators.
- Select Turn On for Every Device to allow all devices, for which you enable the applicable plugin, to discover the indicators associated with the indicator types at the next discovery and poll data. You can only turn on indicator types that display in the Enabled column.
- Select Turn Off for Every Device to stop polling the indicators associated with the indicator types on all devices at the next discovery.
- Select Enable to enable the ability to poll all indicators associated with the indicator types.

Process Poller

The Process object type is enabled by default. There is one Process object type: Process. To poll Process devices, enable both the Process plugin and the SNMP plugin for the device on the New Device page or on the Edit Device page. The Process plugin works in conjunction with SNMP via the HOST-RESOURCES-MIB. The MIB stores information about all currently running processes, including their CPU time and memory utilization.

LIMITATION

The NMS process poller is unable to handle run arguments greater than 128 characters. This is due to the poller's reliance on HOST-RESOURCES-MIB::hrSWRunParameters to fetch the run parameters from the host and the OID being limited to 128 characters as defined in RFC-2790.

Processes group by HOST-RESOURCES-MIB::hrSWRunName, so if 20 SSH sessions are open, they all count as one process with 20 instances. The Process plugin aggregates the values from the combined instances to present the total.

Example

The memory usage for each SSH session is summed together.

SNMP Poller

SNMP object types are enabled by default. To poll SNMP devices, enable the device to send SNMP data to SevOne NMS and enable the SNMP plugin for the device on the New Device page or on the Edit Device page. The MIB Manager enables you to add MIBs which are the foundation for SNMP object types and SevOne Support Engineers can perform a device certification to enable you to add the SNMP object types that are specific to your network.

Device type associations enable you to have devices you assign to the device types you define on the Device Types page automatically attempt to poll the enabled SNMP object type enabled indicators.

The SNMP plugin uses text related to and based on OIDs to create human readable object names and descriptions. This provides the ability to use logical and mathematical expressions to store a resultant value in order to relate OIDs to each other. The SNMP plugin uses this to cross reference OIDs across the device's SNMP tree to gather descriptive information about a particular object. Please refer to SNMP topic for details.

SNMP Object Types

Perform the following steps to manage SNMP object types. For interfaces and most SNMP objects, there is an OID that is dedicated to provide the index number.

Example: Walk ifIndex to yield the following:

RFC1213-MIB::ifIndex.1 = INTEGER: 1
RFC1213-MIB::ifIndex.2 = INTEGER: 2
RFC1213-MIB::ifIndex.8 = INTEGER: 8

SNMP object types are hierarchical. You can disable or enable object types at each level of the hierarchy which means the parent object type can be disabled while the child object type is enabled. Each field on the Add/Edit SNMP Object Type pop-up has a corresponding check box on the right side to enable you to make changes at this level of the hierarchy and below. The changes you make when you select the right-hand check box override and do not affect the parent object type definition.

Click the Filter drop-down and select SNMP Poller to display the SNMP object types in the Object Types hierarchy.
Click Add or click to display the Add/Edit SNMP Object Type pop-up.

When adding/editing an object type at a parent level, Indexed By field is optional. If the Indexed By field is entered, its children will automatically inherit the OID but if needed, it can be changed. However, if the Indexed By field is not entered at the parent level then, when the child object type is created, Indexed By field for the child must be specified.
In the Name field, enter the object type name.
Click the Indexed By to display the SNMP OID Browser where you select the index OID. Perform the following steps on the SNMP OID Browser to select an OID.
1. In the Search field, enter alphanumeric text to filter the OID search.
2. Navigate the OID Tree hierarchy to locate and select an OID.
3. View the OID in the display on the right side of the SNMP OID Browser.
4. Click Select This OID to select the OID.
Select the Reverse Engineer check box to have instances of this object type be uniquely identified by evaluating the OID of the SNMP object specified in the Indexed By field, as opposed to its value. How the values encoded within the OID are evaluated is based on the configuration of the Index Keys field. You should leave this check box selected for the vast majority of object types.
The Index Keys fields enable you to select the index keys to use to determine how to treat the remaining octets after the index. In the Possible Values field, select index keys to assign to the object type (use Ctrl or Shift keys to multi-select) then move the index keys to the Index Keys field. Index keys in the Index Keys field are assigned to the object type and they display in the sequence in which they appear listed. Possible values include the following:
- Integer - A single number that indicates there is a constant amount of numbers following each OID.
- String - A string prefixed with the string length. This typically appears with double quotes.
- String (Implied) - A string with no length information. This must only occur as the last index value.
- Variable - A variable amount of numbers prefixed with the amount of items. This is typically used for IPv4 versus IPv6 indexes.
- Variable (Implied) - A Variable amount of numbers, but with no length information. This must occur as the last index value. This can be used to "eat up" the remainder of the index.
Click the Name Expression to display the SNMP OID Browser where you select the OID that results in a unique name for all object types on a device.
Click the Description Expression to display the SNMP OID Browser where you select the OID to add additional information about the object type.
Click the Subtype to display the SNMP OID Browser where you select the OID to define a subtype for the object type (used for thresholds and reports). This can generate the following variables:

OID High Bits - SNMP version 1 specifications allow for 32 bit, unsigned integer counters. A 32 bit counter increments up to around four billion, then wraps back to zero, and continues. SNMP version 2 introduced 64 bit unsigned integer counters that can count much higher. 64 bit counters have twice the bits and twice the physical capacity of 32 bit counters to make them far more powerful and accurate. Manufacturers had two options to incorporate 64 bit counters.

Create a new 64 bit OID to represent the same thing as the 32 bit version.
Create a second 32 bit OID that represents the high bits of the 64 bit version.

VMware Poller

VMware object types are enabled by default. When you enable the VMware (Logical) and/or the VMware (Physical) topology sources on the Cluster Manager > Cluster Settings tab, these topology sources automatically discover VMware devices and enable the VMware plugin. This expedites the creation of Topology reports. For devices you manually add, the VMware plugin requires device specific configuration and you enable the VMware plugin for the device on the New Device page or on the Edit Device page.

VMware Object Types and Indicator Types

You cannot edit, add, or delete VMware object types or VMware indicator types. Discovery uses the object "objectTypeId" && ("name" || "name" == 'DiskIO' && "instance") to determine if a VMware object is a new object or an existing object with a new moniker.

Synthetic Indicator Types

Synthetic indicator types enable you to perform math on multiple metrics collected from multiple indicators on a single monitored object in order to calculate new KPIs.

Synthetic indicator types behave similar to the Calculation Editor that enables you to create custom calculation objects that perform math on multiple metrics collected from multiple objects and/or multiple synthetic indicators that you poll via the Calculation plugin. These features enable you create your own KPIs even when those KPIs do not exist on a device such as Percentage Loss, Percent Error, and Percent Idle. Synthetic indicators are always gauge type indicators and SevOne NMS evaluates all the indicator values the synthetic indicator uses as if the value is a gauge.

Example: You want to monitor voice gateways to reveal which PRI gets the most or least usage. Typical poll metrics enable you to report on the status of individual bearer channels and not the sum of all channels at any given time. This makes it difficult to monitor and alert on total PRI usage. Synthetic indicators enable you to sum the bearer channel statuses (each channel gets a value of 1 when busy), divide by the total number of bearer channels (23), and then multiply by 100, to collect the desired metric for PRI % usage.

You can define synthetic indicator types for the following plugins: Calculation, Deferred Data, JMX, SNMP, WMI, and xStats.

Click the Filter drop-down and select one of the following: Calculation Poller, Deferred Data, JMX Poller, SNMP Poller, WMI Poller, or xStats Poller to display the object types in the list.
Click on an object type to display its indicator types on the right. If the object type does not have any indicator types, the Add Synthetic Indicator Type button does not appear.

In the Indicator Name field, enter the name of the synthetic indicator type.
In the Description field, enter the name to display.
The Synthetic Indicator Expression field enables you to define the calculation.

If the border around the field turns red, your calculation is invalid and your graph results will be erroneous.
Synthetic Indicator Expression :maxValue modifier

Each indicator in Synthetic Indicator Expression supports the :maxValue modifier. This modifier can be added to any indicator that has the maxValue. The user interface validates the modifier and approves it only if the underlying indicator has a maxValue set. Otherwise, the expression is marked as invalid and cannot be saved. For an expression that is invalid, you will get a pop-up message like Modifier is not available for ${<indicator>:maxValue} where <indicator> does not have a maxValue.

For example,
- ${ifHCInOctets:maxValue} is a valid expression as ifHCInOctets has maxValue.
- ${SMDIMessageCountInbound24Hour:maxValue} is an invalid expression as SMDIMessageCountInbound24Hour does not have maxValue.
The discovered maxValue is retrieved and used for an indicator unless if the maxValue has been overwritten and in that case, the overwritten value is used.
1. Click an indicator type in the Available Source Indicators field and drag it to the Synthetic Indicator Expression field. The Available Source Indicators field contains the indicator types associated to the object type you select in the hierarchy.
2. Enter applicable operators in the Synthetic Indicator Expression field to formulate the calculation. Please refer to section Acceptable Operators below.
3. Drag additional source indicator types and enter additional mathematical symbols to create the expression in the Synthetic Indicator Expression field.
The Maximum Value Expression field enables you to define the indicator type maximum value calculation.

If the border around the field turns red, your calculation is invalid and your graph results will be erroneous.
Maximum Value Expression :maxValue modifier

Each indicator in Maximum Value Expression supports the :maxValue modifier. This modifier can be added to any indicator that has the maxValue. The user interface validates the modifier and approves it only if the underlying indicator has a maxValue set. Otherwise, the expression is marked as invalid and cannot be saved. For an expression that is invalid, you will get a pop-up message like Modifier is not available for ${<indicator>:maxValue} where <indicator> does not have a maxValue.

For example,
- ${ifHCInOctets:maxValue} is a valid expression as ifHCInOctets has maxValue.
- ${SMDIMessageCountInbound24Hour:maxValue} is an invalid expression as SMDIMessageCountInbound24Hour does not have maxValue.
The discovered maxValue is retrieved and used for an indicator unless if the maxValue has been overwritten and in that case, the overwritten value is used.
1. Click an indicator type in the Available Source Indicators field and drag it to the Maximum Value Expression field.
2. Enter applicable operators in the Maximum Value Expression field to formulate the calculation. Please refer to section Acceptable Operators below.

Acceptable Operators

Your expression formula can include the following characters:

+ add
- subtract
* multiply
/ divide
&& logical AND
|| logical OR
<= less than or equal to
>= greater than or equal to
! not equal to
== equal to
> greater than
< less than
^ raise x to the power of y
% modulus
?: if...then...else
isnan is Not a Number. This evaluates to 1 if the value is not a number. Otherwise, it evaluates to 0.
isValid is valid. This evaluates to 1 if the value has been discovered and is not isnan. Otherwise, it evaluates to 0.
useIfValid use if valid. This evaluates to the value if it has been discovered and is not isnan. It evaluates to the second argument otherwise.

If your calculation results in either of the following invalid values, there will be a gap in your graph: Not a Number (NAN) and Infinity (+/-INF). The following is how SevOne NMS attempts to prevent invalid values.
In sequence of processing:

Zero divided by zero results in NAN.
Any positive value divided by zero results in +INF.
Any negative value divided by zero results in -INF.
Zero multiplied by +/-INF results in NAN.
Any value added to, subtracted from, multiplied by, divided by, or divided from NAN results in NAN.
Any value compared to NAN (<, <=, ==, >=, >) results in 0. NAN != NAN.
Any value compared to +INF is less than +INF, except that +INF == +INF
Any value compared to -INF is greater than -INF, except that -INF == -INF
Any value added to or subtracted from +INF results in +INF
Any positive value multiplied by +/-INF results in +/-INF
Any value divided by +/-INF results in 0
