Advisable to remove the Session/Keepalive log data coming from Applications to Azure App Insights

We have a web-application hosted on Azure and it sends Telemetry to App Insights and the Dev team is asking if it is ok to Turn off sending the SESSION/KEEPALIVE data thats being posted from web-application. Will this affect any functionality like User Flows etc in Application Insights? Any guidance on this? Following is sample data:-

timestamp | id | source | name | url | success | resultCode | duration | performanceBucket -- | -- | -- | -- | -- | -- | -- | -- | -- 2019-09-25T16:00:31.8191577Z | \|Ac34D.9fIx+.4c3e0b35_ | POST session/keepalive | http://XXXXXXXXXXXXXX.com/session/keepalive | TRUE | 200 | 15.8274 | <250ms 2019-09-25T16:00:42.7423811Z | \|Ac34D.FqSNy.83ee6e0d_ | POST session/keepalive | http://XXXXXXXXXXXXXX.com/session/keepalive | TRUE | 200 | 38.3679 | <250ms 2019-09-25T16:00:48.716939Z | \|Ac34D.h8kwN.34c0b012_ | POST session/keepalive | http://XXXXXXXXXXXXXX.com/session/keepalive | TRUE | 200 | 16.0359 | <250ms 2019-09-25T16:00:54.1607213Z | \|Ac34D.v2qfF.4c3e0b36_ | POST session/keepalive | http://XXXXXXXXXXXXXX.com/session/keepalive | TRUE | 200 | 15.2518 | <250ms

Views in Applications Insights typically target a specific set of telemetry item types.

For instance, user flows UI leverages PageView and CustomEvent telemetry types. Therefore, if keep alive is reported as one of those types it will be displayed in that UI.

However, if the example above is Dependency telemetry, then that view won't be affected.

In general, if you'd like to drop some of the telemetry before it reaches AI and is processed for storage, you'd use TelemetryProcessor (in case of Java Script SDK, TelemetryInitializer) to filter it out:

var telemetryInitializer = (envelope) => {
  if (envelope.data.someField == 'keepalive') return false;
};
appInsights.addTelemetryInitializer(telemetryInitializer);
