You can view the collected data in various BMC Helix applications and derive the following benefits:
BMC Helix application | Type of data collected or viewed | Benefits |
---|---|---|
BMC Helix Operations Management | Events | Use a centralized event view to monitor and manage events, perform event operations, and filter events. Identify actionable events from a large volume of event data by processing events. For more information, see Monitoring events and reducing event noise. |
BMC Helix Discovery | Topology | Collect all CIs from Micro Focus NNMiin BMC Helix Discovery. Collect services from Micro Focus NNMiin BMC Helix Discovery in a format that can be consumed by BMC Helix AIOps. For more information, see Managing your IT infrastructure. |
BMC Helix AIOps | Situations (created from events) | Improve the mean time to resolve (MTTR) based on the situation-driven workflow. Lower the mean time to detect or discover (MTTD) and the time required for investigating tickets. For more information, see Monitoring situations. |
BMC Helix AIOps | Services (created from topology) | Monitor the overall health of a service. When the service gets impacted by any factor, view the events generated because of the impact, analyze the causes of the impact, and quickly remediate those events to restore the health of the impacted service. For more information, see Monitoring services. |

✅️ Data Collection Window Specify the historical time period (in minutes)
from the current time for which the data should
be collected.
Default: 5 minutes
Example: Collection Schedule is set to 5 mins.
Data Collection Window is set to 5 mins.
Current time is 00:30.
If you run the collector just after 00:30, data is
collected first at 00:30 for the interval 00:25 -
00:30, and next at 00:35 for the interval 00:30 -
00:35, and so on.
For more information about how this parameter
affects data collection, see Data collection
window.✅️
❌ Data Latency Specify the time (in minutes) by which the data
time window should be shifted back on the
timeline.
This parameter is useful in delayed data
availability situations.
Default: 0 minutes
Example: Collection Schedule is set to 5 mins.
Data Collection Window is set to 10 mins.
Data Latency is set to 2 mins.
Current time is 00:30.
If you run the collector just after 00:30, data is
collected first at 00:30 for the interval 00:18 to
00:28 and next at 00:35 for the interval 0:23 to
00:33, and so on.
For more information about how this parameter
affects data collection, see Data latency.✅️

This list of nature is updated automatically from
Micro Focus NNMi.✅️
❌ Source Select all or a subset of sources from the list.
This list of source is updated automatically from
Micro Focus NNMi.✅️
❌ Severity
Select all or a subset of severities from the list.
This list of severities is updated automatically
from Micro Focus NNMi.✅️
❌ Max Items Returned Specify the value for the maximum number of
items returned per data type.
BMC Helix Intelligent Integrations Micro Focus
NNMi connector collects the metrics data for
four different data types, for example, Devices,
Interfaces, IPAddresses, and L2Connections.
Default value: 1000.✅️ ✅️ Excluded Security Groups Select all or a subset of groups for which you
don't want to collect events.
This list of security groups is updated
automatically from Micro Focus NNMi.✅️ ❌ Source Node Name Allowlist Specify the source node name allowlist.
This list of node groups is updated
automatically from Micro Focus NNMi.✅️ ❌ Node Groups Specify the node groups to collect topology
data for the nodes, interfaces, and IP addresses
kind of resources that belong to the specified
groups.
Each node group is a collection of multiple
nodes and their associated interfaces and IP
addresses. This list of node groups is updated
automatically from Micro Focus NNMi.✅️ ❌ Filter by status Select this option to collect the topology data
for the nodes, interfaces, L2Connections that
belong to any status, except NOSTATUS.✅️ ❌ L2Connection name match
patternSpecify the pattern to collect the topology data
for L2Connections whose names match the
pattern.
L2Connection names are formed based on the
nodes and interfaces that are situated at both
ends of the connection, in the format
<nodeName>[interfaceName],<nodeName>[in
terfaceName].
For example, NYC-Aironet-C1600-
AP-2[Gi0],NYC-Cisco-NEXUS9000-
Switch[Ethernet1/3] is the L2Connection name,
where, NYC-Aironet-C1600-AP-2 and Gi0 are
the node and interface at one end of a
L2Connection and NYC-Cisco-NEXUS9000-
Switch and Ethernet1/3 are the node and
interface at the other end of that connection.
So, to collect the topology data for all
L2Connections with names having with text
NEXUS9000, specify the pattern as
%NEXUS9000%.✅️ ❌ Max Batch Size Specify the maximum size of each batch to split
up the queries for collecting topology data.
It is applicable for devices, interfaces, IP
addresses, and L2Connections. For example, to
collect topology data from 5000 devices, if you
specify the maximum batch size as 100, then
the query splits up into 50 batches, where each
batch collects topology data from a set of 100
devices.✅️ ❌ - Duration: When you select this option, data collection happens constantly. Specify the schedule in minutes, hours, or days.
- Click CREATE COLLECTORS to create the required collector streams for the selected data type.
- Click a data type and specify the configuration parameters in the Distributors section as described in the following table:
Parameter name
Description
Max Batching Size
Specify the maximum number of data items to send in a single POST request to the destination API.
The batch size depends on the destination’s ability to buffer the incoming data.
Default: 250Max Batching Delay
Specify the maximum time (in seconds) to wait before building and processing a batch.
Default: 3 secondsBase Retry Delay
Specify the initial time (in seconds) for which to wait before retrying to build and process a batch.
The waiting time increases in the following sequence: n1, n2, n3, and so on, where n indicates the number of seconds.
Default: 2 seconds
Example: Base Retry Delay is set to 2 seconds.Retry is performed after 2, 4, 8, 16, ... seconds.Max Intra-Retry Delay
Specify the maximum limit for the base retry delay.
Default: 60 seconds
Example: Max Intra-Retry Delay is set to 60 seconds.
Base Retry Delay is set to 2 seconds.Retries are performed 2, 4, 8, 16, 32,... seconds later.Max Retry Duration
Specify the total time for retrying a delivery. For REST destinations, a delivery is a batch of data items in one POST request.
Default: 5 minutes
Example: Max Retry Duration is set to 8 hours. Base Retry Delay is set to 2 seconds.
Requests are sent for 2+4+8+16+32+64+132... until 8 hours in total duration is reached. After that, no subsequent attempts are made to retry the delivery. The assumption here is that if there is an outage or other issue with the destination tool, recovery should take less than the value of the Max Retry Duration parameter to be completed.Attributes To Be Dropped When Updating Events
Specify the event attributes that you do not want to be updated in BMC Helix Operations Management when events are updated.
For example, if you do not want an event's severity, source address, source category, and subcategory to be updated in BMC Helix Operations Management, you need to specify those attributes in a comma-separated format: severity,source_address,source_category, source_subcategory.
Important: You can obtain the event attribute names in BMC Helix Operations Management, by exporting any event data in JSON, BAROC, XML, or CSV format. The exported file contains all attributes of the event data, and from there you can identify the attributes to be dropped. - Click CREATE DISTRIBUTORS to create the required distributor streams for the selected data type.
Click one of the following buttons:
- SAVE STREAM: Click this button if you want to edit the integration details before creating the instance. After you save the stream, the connector that you just created is listed in the SOURCES panel. Move the slider to the right to start the data stream.
- SAVE AND START STREAM: Click this button if you want to save the integration details and start receiving data immediately. For more information about data streams, see Starting-or-stopping-data-streams.
Task 3: To verify the integration
In BMC Helix Intelligent Integrations , on the SOURCES panel, confirm that the data streams for the integration you created are running. Data streaming is indicated by moving colored arrows.
- A moving red arrow (
) indicates that the event stream is running. Event data will be pushed according to the configured Collection Schedule interval.
- A moving light blue arrow (
) indicates that the topology stream is running. Topology data will be pushed according to the configured Collection Schedule interval.
