+Every notification identifies:  
+* The type of resource with the problem (`Application`, `Deployment`, `Pod`)
+* If it is health or sync related 
+* If it is a warning or error.
+
+All errors are Argo CD-generated errors. Codefresh generates custom warnings for the following:
+
+{::nomarkdown}
+<br>
+{:/}
+
+#### Warning: Missing Rollouts reporter in cluster
+
+**Reason**: Codefresh has detected that Argo Rollouts is not installed on the target cluster. Rollout instructions are therefore not executed and the application is not deployed.  
+Applications with `rollout` resources need Argo Rollouts on the target cluster, both to visualize rollouts in the Applications dashboard and control rollout steps with the Rollout Player.  
+
+**Corrective Action**: Click **Install** and install Argo Rollouts on the target cluster.
+
+{::nomarkdown}
+<br>
+{:/}
+
+#### Warning: Long sync 
+**Reason**: Ongoing sync for application exceeds 30 minutes (Argo CD's default duration for a sync operation).
+
+**Corrective Action**: 
+* Click **View Details** to take you directly to the Sync Result tab. 
+  Here you can see details on the sync job that was started, and info on the Hooks if any. Failed hooks are dsiplayed at the top. 
+* To see more details such as the message and sync duration, switch to **Sync Info**.
+* To stop the sync operation, click **Terminate**. 
+* Drill down into the application to investigate the issue and make changes.

+#### Filters for application resources
+Filters are common to both Tree and List views, and when applied are retained when switching between views. 
+
+`IgnoreExtraneous` is a filter in [Argo CD](https://argo-cd.readthedocs.io/en/stable/user-guide/compare-options){:target="\_blank"} that allows you to hide specific resources from the Current State views. These resources are usually generated by a tool and their sync statuses have no impact on the sync status of the application. For example, `ConfigMap` and `pods`. The application remains in-sync even when such resources are syncing or out-of-sync.  
+
+>The `IgnoreExtraneous` filter applies only to the sync status. The health status of the resource directly affects the application's health status. If the resource is degraded, then the application is also degraded. 
+
+**For the `IgnoreExtraneous` filter to be effective:**  
+
+* Add `IgnoreExtraneous` as an annotation to the resource, as in the example below of the `ConfigMap` resource.
