Measures reported by CtxNsAppFlowTest
The Citrix® NetScaler® appliance is a central point of control for all application traffic in the data center. It collects flow and user-session level information valuable for application performance monitoring, analytics, and business intelligence applications. The AppFlow freature, when enabled on the NetScaler, transmits this information by using the Internet Protocol Flow Information eXport (IPFIX) format, which is an open Internet Engineering Task Force (IETF) standard defined in RFC 5101. Using UDP as the transport protocol, AppFlow transmits the collected data, called flow records, to one or more IPv4 collectors. The collectors aggregate the flow records and generate real-time or historical reports.
To enable administrators to promptly detect bottlenecks (if any) in the transmission of flow records to configured collectors, the NS Application Flows test runs periodic checks on data transmissions from the NetScaler appliance. .
The measures made by this test are as follows:
| Measurement |
Description |
Measurement Unit |
Interpretation |
| Appflow_trans |
Indicates the number of Appflow flows transmitted by the NetScaler during the last measurement period. |
Number |
|
| Appflow_not_trans |
Indicates the number of Appflows that were not transmitted during the last measurement period. |
Number |
A high value is indicative of a transmission bottleneck. This could be owing to improper collector configuration or a bad network link between the appliance and the collector. |
| Appflow_octets_trans |
Indicates the amount of Appflow octets transmitted by the NetScaler during the last measurement period. |
MB |
|
| Appflow_octets_not_trans |
Indicates the amount of Appflow octets that were not transmitted during the last measurement period. |
MB |
A high value is indicative of a transmission bottleneck. This could be owing to improper collector configuration or a bad network link between the appliance and the collector. |
| Appflow_octets_ignored |
Indicates the amount of octets that were ignored by the NetScaler during the last measurement period. |
MB |
|
| Appflow_pkts_ignored |
Indicates the number of Appflow packets ignored by the NetScaler during the last measurement period. |
Number |
|
| Appflow_pkts_not_trans |
Indicates the number of Appflow packets that were not transmitted by the NetScaler during the last measurement period. |
Number |
A high value is indicative of a transmission bottleneck. This could be owing to improper collector configuration or a bad network link between the appliance and the collector. |
| Appflow_msgs_trans |
Indicates the number of Appflow messages transmitted by the NetScaler during the last measurement period. |
Number |
