LogViewer

LogViewer allows you to filter and view log entries and perform much more complex search queries to help you find the log entries that you are interested in your Externable portal.

You can find the log viewer in the settings section.

How it helps

Have you ever wanted to find all log entries which contains the same request ID or find all items in the log where a property called duration is greater than 1000ms? With the power of structured logging and a query language we are able to search and find log items for very specific scenarios. When debugging the client site you should now have more power to see and find patterns in your log files and get rid of those pesky errors.

Example queries

Here are a handful example queries to get you started, however the saved searches contain some further examples. For more details on the syntax head over to the https://github.com/serilog/serilog-filters-expressions project.

Find all logs that are from the namespace 'Umbraco.Core'
StartsWith(SourceContext, 'Umbraco.Core')

Find all logs that have the property 'Duration' and the duration is greater than 1000ms
Has(Duration) and Duration > 1000

Find all logs where the message has localhost in it with SQL like
@Message like '%localhost%'

Saved Searches

When writing a custom query that you wish to use often, it is possible to save this and use the dropdown to re-use your saved search. To add a new saved search, use the search box to type your query and click the star icon. In doing so you can give it a friendly name.
