Issue/Introduction

AppNeta is integrated with DX NetOps Virtual Network Assurance (VNA) using the AppNeta plugin.

VNA is integrated with DX NetOps Performance Management Portal and Data Aggregator.

Data from the AppNeta plugin was visible in reports but no longer is.

In the VNA oc.log file we see errors like this.

ERROR (EE-ManagedThreadFactory-default-Thread-3479)  [OC_ACQUISITION] TimHttpFunction 301  Error while sending http request to https://<hostName>/api/v3/path/data?from=1702570200568&api_key=v3&limit=500&page=1 : java.io.IOException: Server returned HTTP response code: 400 for URL: https://<hostName>/api/v3/path/data?from=1702570200568&api_key=v3&limit=500&page=1

Environment

All supported DX NetOps releases

All supported DX NetOps Virtual Network Assurance (VNA) releases

All supported DX NetOps Performance Management releases

Cause

The VNA host is not synchronized for time. As a result, the requests for data from AppNeta were sent with times in the future. This caused AppNeta to reject the requests.

The "timedatectl status" command will show the problem when run on the VNA host. In this case we saw:

timedatectl status
    Local time: Wed 2023-12-13 11:12:40 MST
    Universal time: Wed 2023-12-13 18:12:40 UTC
    RTC time: Wed 2023-12-13 18:02:02
    Time zone: America/Phoenix (MST, -0700)
    System clock synchronized: no
    NTP service: inactive
    RTC in local TZ: no

The lack of time synchronization will cause this. Time synchronization on the VNA host is a requirement.

 

Resolution

Set up a time synchronization tool on the VNA host. Restart the VNA wildfly service.

Additional Information

The steps from the Portal Verify Time Synchronization documentation topic could be used to resolve this following those steps on the VNA host.
