Hi,  
is there any bash script or useful commands to debug / search better in wowzastreamingengine\_access.log and filter out everything which is not that relevant? I often search that log and try to find Problems which explains, why a livestream not worked anymore, etc.

In addition to the option to filter log messages in the Engine UI as shown below, I will share a second option with you as well:

1. **In the Engine UI** , click [HERE](https://www.wowza.com/docs/how-to-view-log-messages-in-wowza-streaming-engine-manager)

1. **Download the logs from Engine**

Use a text editor to filter out your search based on the error and warning fields shown in the UI screenshot above.  
Lots of articles and tools will help you run a filtered search but I just don’t have a Wowza article that shows this, but you can find out how
