     -  If your Prometheus server is within the same Kubernetes cluster, add a new Prometheus job to configure Prometheus for directly exporting from a NetScaler CPX pod. For more information, see [kubernetes_sd_config](https://prometheus.io/docs/prometheus/latest/configuration/configuration/#kubernetes_sd_config). A sample Prometheus job is given as follows:
 
-            ```
-                    - job_name: 'kubernetes-cpx'
-                    scheme: http

-                        args: ['filename:metrics_prom_ns_analytics_time_series_profile.log,filelocation:/var/nslog']
