Application Delivery Management

Operations

Operations is an optional section in a StyleBook. In this section, you can configure NetScaler Application Delivery Management (ADM) analytics to collect AppFlow records on all or some of the traffic transactions. The virtual server created on a NetScaler instance by using the StyleBook handles these traffic transactions. In this section, you can also configure NetScaler ADM to trigger alarms when certain traffic conditions are met on a virtual server.

You can configure NetScaler ADM through StyleBooks to collect traffic statistics from various NetScaler ADM Insights that are listed as follows:

  • Web Insight
  • WAF Security Violations
  • HDX Insight
  • NetScaler Gateway Insight.

The virtual servers supported are load balancing, content switching, and VPN virtual servers.

Enable both Web Insight and WAF Security Violations or one of them for analytics on a load balancing or content switching virtual server. For VPN virtual servers, however, you must enable both HDX Insight and NetScaler Gateway Insight or one of them.

Any NetScaler ADM Insight enabled on NetScaler instances through StyleBooks uses the IPFIX protocol (AppFlow) to send the data from the instances to NetScaler.

Also, when you enable Web Insight, Client-Side Measurements is enabled on the load balancing and the content switching virtual servers. With client side measurements enabled, ADM captures load time and render time metrics for HTML pages, through HTML injection. Using these metrics, admins can identify L7 latency issues.

Example 1:

The following example shows how to write the operations section in a StyleBook to enable both HDX Insight and NetScaler Gateway Insight on a VPN virtual server:


name: simple-vpn-ops
namespace: com.example.stylebooks
schema-version: "1.0"
version: "0.1"
description: Test StyleBook to enable hdxinsight and gatewayinsight on a VPN vserver
import-stylebooks:
  -
    namespace: netscaler.nitro.config
    version: "10.5"
    prefix: ns
components:
    -
        name: vpnvserver-comp
        type: ns::vpnvserver
        properties:
            name: str("vpn-") + str($current-target.ip)
            servicetype: SSL
            ipv46: 1.1.21.37
            port: 443
operations:
    analytics:
        -
            name: comp-ops
            properties:
                target: $components.vpnvserver-comp
                filter: "true"
                insights:
                  -
                 type: hdxinsight**
                  -
                    type: gatewayinsight
outputs:
  -
    name: myvpns
    value: $components.vpnvserver-comp

Example 2:

The following example shows how to write the operations section in a StyleBook to enable both Web Insight and WAF Security Violations on a load balancing virtual server:


name: simple-lb-ops
namespace: com.example.stylebooks
schema-version: "1.0"
version: "0.1"
description: Test StyleBook to enable webinsight and securityinsight on LB vserver
import-stylebooks:
  -
    namespace: netscaler.nitro.config
    version: "10.5"
    prefix: ns
components:
    -
        name: lbvserver-comp
        type: ns::lbvserver
        properties:
            name: str("lb-") + str($current-target.ip)
            servicetype: HTTP
            ipv46: 1.1.21.37
            port: 80
operations:
    analytics:
        -
            name: comp-ops
            properties:
                target: $components.lbvserver-comp
                filter: "true"
                 insights:
                 -
                  type: webinsight
                   -
                  type: securityinsight
outputs:
  -
    name: mylbs
    value: $components.lbvserver-comp
