Guidelines and Limitations

  • In Nexus Dashboard Insights, Integrations are supported on both Management and Data networks.

  • By default, Nexus Dashboard Insights will use Data network to connect to the Integrations such as vCenter server, DNS, AppDynamics, Nexus Dashboard Orchestrator. If you want to use Management network, you can add a specific route in Nexus Dashboard from Admin > System Settings > General > Routes. The route can be a /32 pointing to Integrations or a larger subnet that includes it.

AppDynamics Integration

About AppDynamics Integration

Cisco Nexus Dashboard Insights provides the ability to monitor the most common and complex challenges in the maintenance of infrastructure operations, which involves monitoring, troubleshooting, identification and resolving the network issues.

AppDynamics provides application performance management (APM) and IT operations analytics that helps manage the performance and availability of applications in the data center. It also provides the required metrics for monitoring, identifying, and analyzing the applications that are instrumented with AppDynamics agents.

AppDynamics is associated only at the Site level. Onboarding of the AppDynamics controller is only at the Site level.

AppDynamics hierarchy consists of the following components:

  • Network Link—Provides the functional means to transfer data between network entities.

  • Node—A working entity of an application and is a process running on a virtual machine.

  • Tier—Grouping of nodes into a logical entity. Each tier can have one or more nodes.

  • Application—A set of tiers make up an application.

  • Controller—A controller consists of a set of accounts with each account comprising a list of applications. Each account in the controller is an instance.

Integrating AppDynamics allows Nexus Dashboard Insights to collect operational data and metrics of the applications monitored by AppDynamics, and then correlate the collected information with the data collected from the Cisco ACI site.

In a scenario where an application communicates through the Cisco ACI site, AppDynamics provides various metrics about the application and the network, which can be used to isolate the cause of the anomaly. The anomaly can be in the application or the underlying network. This in turn allows network operators to monitor the network activity and detect anomalies.

The AppDynamics agents are plug-ins or extensions, hosted on the application. They monitor the health, and performance of the network nodes and tiers with minimal overhead, which in turn report to the AppDynamics controller. The controller receives real-time metrics from thousands of agents and helps troubleshoot and analyze the flows.

Nexus Dashboard Insights connects to the AppDynamics controller and pulls the data periodically. This data from AppDynamics controller, rich in application specific information is fed to Nexus Dashboard Insights, thereby providing Cisco Nexus Dashboard Insights for the traffic flowing through the Cisco ACI site.

From AppDynamics, you can create your own health rule on the available metrics, which contributes to the overall anomaly score of the entity.

The integration of Nexus Dashboard Insights with AppDynamics enables the following:

  • Monitoring and presenting AppDynamics hierarchy in Nexus Dashboard Insights.

  • Gathering and importing network related metrics into the Nexus Dashboard Insights.

  • Presenting statistics analytics, flow analytics, and topology view on the data collected from AppDynamics controller.

  • Detecting anomaly trends on metrics collected from AppDynamics controller and raising anomalies on detection of such events.

  • The AppDynamics integration uses API server and multiple instances of Telegraph data collecting container to support load balancing of the onboarded controllers.

  • Fabric flow impact calculation for AppDynamics anomalies.

Onboarding for SaaS or Cloud Deployments

Starting from Nexus Dashboard Insights release 6.0.2, you can connect to AppDynamics controller using a proxy for SaaS or cloud deployments. For onboarding an AppDynamics Controller running on cloud, Nexus Dashboard Insights uses proxy configured on Cisco Nexus Dashboard to connect to AppDynamics Controller.

Guidelines and Limitations

  • After Nexus Dashboard Insights upgrade, AppDynamics takes about 5 minutes to report the information in AppDynamics GUI.

  • The health and count of AppDynamics business transactions displayed in the application details do not match the flow count in Nexus Dashboard Insights.

  • Nexus Dashboard Insights does not support fabric topologies as transit-leaf does not have the VRF deployed and flow table in transit-leaf will not export the flow record to Nexus Dashboard Insights. Hence Nexus Dashboard Insights will not stitch the path fully and will not display complete path summary with all the information.

  • To connect an HTTPS AppDynamics controller using an HTTP proxy you must configure HTTPS proxy in Nexus Dashboard with the HTTP proxy server URL address.

  • To connect an HTTP AppDynamics controller using an HTTP proxy you must configure HTTP proxy in Nexus Dashboard with the HTTP proxy server URL address.

  • Configuration import and export are not supported for AppDynamics integrations.

  • Scale limits for AppDynamics integration:

    • Number of apps: 5

    • Number of tiers: 50

    • Number of nodes: 250

    • Number of net links: 300

    • Number of flow group: 1000

Installing AppDynamics

Before you begin using Nexus Dashboard Insights Integrations, you must install AppDynamics Application Performance Management and Controller. See Getting Started for details.

Onboard AppDynamics Controller

Use this procedure to onboard a AppDynamics Controller on to Nexus Dashboard Insights using GUI. For Cisco Nexus Dashboard Insights and AppDynamics integration, the Cisco Nexus Dashboard’s data network must provide IP reachability to the AppDynamics controller. See the Cisco Nexus Dashboard Deployment Guide.

Before you begin

  • You must have installed AppDynamics application and controller.

  • You must have administrator credentials for Nexus Dashboard Insights.

Each controller supports multiple account names for the same host name. Each account name supports multiple applications monitored by the controller. Therefore, a controller can support multiple applications monitored by AppDynamics.

Nexus Dashboard Insights and AppDynamics Integration Dashboard

The AppDynamics Dashboard allows you to onboard controllers and presents a view of the Top 5 Applications by Anomaly Score along with various metrics. Once a controller is onboarded, data related to applications monitored by that controller is pulled by Nexus Dashboard Insights. It can take up to 5 minutes for the first set of data to appear on the GUI. The AppDynamics health state information provided for each entity is aggregated and reported by Nexus Dashboard Insights on the dashboard.

The AppDynamics dashboard displays the overview of the applications monitored by the AppDynamics controller.

  • Controller Connectivity - represents the number of integrations that are Up or Down.

  • Anomalies by Severity — The Nexus Dashboard Insights runs statistical analytics on the metrics received from the AppDynamics controller.

  • Top 5 Applications by Anomaly Score - displays top five out of all the applications based on the anomaly score.

  • Anomalies by Severity - to see the Anomalies page.

  • Application Widget - displays the top application by anomaly score. This includes the anomaly score of the application as computed in Nexus Dashboard Insights, health state of tiers and nodes as reported by AppDynamics. Click the widget for additional details about the monitored application.

Topology View

The topology view represents the stitching between nodes where these nodes are connected to the Cisco ACI site.

The topology view includes application nodes and leaf nodes. Toggle between show or not show to view/hide the nodes with anomaly score. The anomaly score is represented by the dot in the topology.

The topology view represents a hierarchical view of Application > Node > Cisco ACI Leaf and the links between them with a logical or network view of how various objects are related.

AppDynamics Anomalies

From AppDynamics application, you can create your own health rule on the available metrics, which contributes to the overall anomaly score of the entity. If the health rules are violated and a violation is generated by the AppDynamics controller, then Nexus Dashboard Insights pulls these health violations and generates anomalies on these violations.

The anomalies in the summary table include the following:

  • Anomalies raised on the metrics from the AppDynamics controller.

  • Health violation on the network metrics that the AppDynamics controller raised.

  • Anomalies at the application level and node level.

If there is an anomaly on the interface of application(s) impacted by the interface, then an anomaly is identified and shown.

Depending on the anomaly score and the level at which the anomaly occurs, the corresponding flows impacted are identified. Information related to the flow metrics with the Cisco ACI leaf information enable statistics analytics, pin point the source of the anomaly, whether it is the application or network, and the impacted entities.

The fabric flow impact calculation for AppDynamics anomalies calls flow APIs to fetch the fabric flows corresponding to the AppDynamics flow groups that were affected by the anomaly. Nexus Dashboard Insights app displays the top 100 fabric flows ordered by the anomaly score for AppDynamics anomalies.

DNS Integration

About DNS Integration

The Cisco Nexus Dashboard Insights Domain Name System (DNS) integration feature enables the name resolution feature to telemetry data. DNS integration can be associated at the Site level.

For DNS integration you can use any of the following 3 data source methods:

DNS File Upload

This method is simple because mappings do not change often. In the GUI, you can upload a file containing mappings. Use one of the supported formats (.csv and .json). Cisco Nexus Dashboard Insights verifies the integrity of the file.

If no VRF, or Site name, or Tenant information is specified, DNS will be applied to the sites for which the DNS server is configured based on the selections in Add Integrations and Associations section. If the DNS server is configured for a site, then DNS will be applied to all the sites in the group.

The DNS file upload size is limited to 1.8 MB.

Example CSV file

This section provides an example of a CSV file’s contents.

recordType  fqdn            ips         siteName    tenant          vrf
dnsEntry    WebSrv1.foo.com 10.101.11.1 ACI-Fab1    prod            vrf_prod
dnsEntry    WebSrv2.foo.com 10.101.11.2 ACI-Fab1    prod            vrf_prod
dnsEntry    WebSrv3.foo.com 10.101.11.3 ACI-Fab1    prod            vrf_prod
dnsEntry    WebSrv4.foo.com 10.101.11.4 ACI-Fab1    prod            vrf_prod
Example JSON file

This section provides an example of a JSON file’s contents.

[
    {
        "recordType": "dnsEntry",
        "fqdn": "WebSrv1.foo.com",
        "ips": [
            "10.101.11.1"
        ]
    },
    {
        "recordType": "dnsEntry",
        "fqdn": "WebSrv2.foo.com",
        "ips": [
            "10.101.11.2",
            "52::2"
        ]
    },
    {
        "recordType": "dnsEntry",
        "fqdn": "WebSrv3.foo.com",
        "ips": [
            "10.101.11.3",
            "52::3"
        ]
    },    {
        "recordType": "dnsEntry",
        "fqdn": "WebSrv4.foo.com",
        "ips": [
            "10.101.11.4",
            "10::101:0:4"
        ]
    }
]

DNS Query

Use this method one query at a time to retrieve data from the DNS server using reverse lookup. Reverse lookup zone(s) must be configured on the DNS server.

Cisco Nexus Dashboard Insights queries the DNS server at regular intervals and resolves IP addresses that are learned using endpoints.

Cisco Nexus Dashboard Insights allows one primary and multiple secondary DNS servers, the primary DNS server will be polled first. If the resolution does not succeed, the secondary servers will be polled thereafter.

DNS Zone Transfer

DNS Zone Transfer is also known as AXFR downloads. Nexus Dashboard Insights can retrieve zone data in bulk from the DNS server using AXFR downloads. This method is convenient for large quantities of data as you no longer have to work on one query at a time.

A zone transfer requires at least one DNS zone. If you configure a forward mapping zone, then all the A and AAAA records will be fetched from a DNS server if you configure a reverse mapping zone, then PTR records will be fetched. When onboarding the DNS server, you must provide a list of zones from which to fetch the data. Cisco Nexus Dashboard Insights will fetch the data from each zone configured from the DNS server.

TSIG (transaction signature) is a computer-networking protocol defined in RFC 2845. Primarily it enables the DNS to authenticate updates to a DNS database. For a secure transfer, Cisco Nexus Dashboard Insights allows you to configure the TSIG key for a zone to initiate the transaction. Configure the zone with the TSIG key, and an associated algorithm. In the Cisco Nexus Dashboard Insights GUI, the supported algorithms are displayed in a drop-down list.

When you delete an onboarded DNS server, all the zones will be un-configured automatically. A zone can be a forward mapping or a reverse mapping zone.

When information is changed on the DNS server it may take up to 3 hours to update corresponding name mappings on Cisco Nexus Dashboard Insights. During that interval, the old name will be displayed for endpoints until the sync is completed.

Guidelines and Limitations

  • DNS onboarding can be done at a site level.

  • Only one type of DNS integration method is supported in one site. For example, in a site, you cannot configure using DNS file uploads as well as DNS Zone Transfer methods.

  • Multiple DNS integration onboarding of the same type is allowed in a site. For example, multiple files can be onboarded, to a site using the DNS file uploads method.

  • If you perform DNS integration onboarding for multiple sites, you cannot also onboard a site in that group.

  • When a corrupted or malformed .CSV of .JSON file is uploaded to the DNS server, Cisco Nexus Dashboard Insights raises system anomalies. However, the connectivity status of the third-party onboarding server, remains in the initialized state and does not change to display a failed state. If the third-party onboarding server remains in the initialized state, check the system anomalies for any anomalies related to the specific integration.

  • The supported scale for DNS integration is 40,000 DNS entries. For vND application profiles, the supported scale for DNS integration is 10,000 DNS entries.

  • Data from DNS servers will be polled or refreshed every 3 hours. So, any changes in the mapping on the DNS server will reflect after the next polling cycle.

Panduit PDU Integration

Panduit PDU Integration

Panduit Power Distribution Unit (PDU) Integration in Nexus Dashboard Insights enables you to monitor energy usage and unlock sustainability insights for sites and individual devices connected to a Panduit PDU. Monitoring energy consumption gives you insight into how much electricity your devices and/or Panduit PDUs are using.

The workflow for integration of Panduit PDU consists of the following steps:

  1. Install Panduit PDU collector and PDUs.

  2. Add PDU collector to Nexus Dashboard Insights. The PDU collector collects telemetry from PDUs in your environment.

  3. Associate PDUs to the PDU collector. The associated PDUs sends telemetry to the Panduit PDU collector, and Nexus Dashboard Insights displays PDU statistics in the Sustainability Report. See Sustainability Report.

Prerequisites

  • You have installed Panduit Collector and PDUs. See Panduit Data Collector for Cisco Nexus Dashboard.

  • You have associated the PDUs to the collector.

  • You have configured a persistent IP address for PDU collector to stream telemetry information for one or multiple PDUs in your site in Nexus Dashboard. In Nexus Dashboard, navigate to Admin > System Settings > General > External Service Pools > Add Data Service IP Address to configure the persistent IP address.

  • You have configured the SNMP protocol in the PDU. See Simple Network Management Protocol.

Guidelines and Limitations

  • After you onboard the PDU collector in Nexus Dashboard Insights, it will take at least 15 minutes for the number of number of devices powered by the PDU collector to be displayed in the Nexus Dashboard Insights GUI.

  • Once the number of number of devices powered by the PDU collector to be displayed in the Nexus Dashboard Insights GUI, the PDU data is updated every 15 minutes in Nexus Dashboard Insights.

  • If the PDU collection status is Not OK, see the Troubleshooting section in the Installation Guide to check the streaming issues.

  • Scale limits for Panduit PDU integration:

    • Maximum number of PDUs supported per Nexus Dashboard cluster - 1000

    • Maximum number of PDUs supported per fabric - 500

  • If you have not configured the PDU name in the Panduit PDU GUI, the PDU name is not displayed in the PDU table in Nexus Dashboard Insights.
