# Logs and errors components

| [cErrorHandler](https://help.qlik.com/talend/r/en-US/7.3/mediation-components/mediation-logs-and-errors/cerrorhandler) | Processes errors in the message routing. |
| --- | --- |
| [cIntercept](https://help.qlik.com/talend/r/en-US/7.3/mediation-components/mediation-logs-and-errors/cintercept) | Intercepts each message sub-route and redirects it in another sub-route without<br>modifying the original one. When this detour is complete, message routing to the originally<br>intended target endpoints continues. This can be useful at testing time to simulate error<br>handling. |
| [cLog](https://help.qlik.com/talend/r/en-US/7.3/mediation-components/mediation-logs-and-errors/clog) | Logs message exchanges in a Route. |
| [cOnException](https://help.qlik.com/talend/r/en-US/7.3/mediation-components/mediation-logs-and-errors/conexception) | Catches the exceptions defined and triggers certain actions which are then<br>performed on these exceptions and the message routing. |
| [cTry](https://help.qlik.com/talend/r/en-US/7.3/mediation-components/mediation-logs-and-errors/ctry) | Offers the Java equivalent exception handling abilities by building<br>Try/Catch/Finally blocks to isolate the part of your Route likely to generate an error,<br>catch the errors, and execute final instructions regardless of the errors. |
