NLog Logs
NLog is a widely used logging framework in windows .NET Application and C#. Site24x7 AppLogs is a one of a kind cloud based log management service that helps you manage logs with ease. Site24x7 agent automatically detects NLog based logs in your machine and identifies the log fields such as date & time, log level, logger name, and message. With default support for NLog logs, you can search, view, collect and analyze the data with the help of the intuitive web client. Learn more about log management with Site24x7.
You can push your NLogs using either of the below methods:

- Go to Admin > AppLogs > Log Profile and Add Log Profile.

- NLog logs are sourced from the below-mentioned folder path. If you have logs in a different folder, you can mention them under the List of files to search for logs to source them from that folder while creating a log profile.
C:\\NLog\\.log

Log pattern
$DateTime:date$ $LogLevel$ $SourceFileName$ $Line:number$ - $Message$
This is the default pattern defined by Site24x7 for parsing NLog logs based on the sample log mentioned below.
Sample log
2017-07-02 20:52:39,342 DEBUG className 200 - This is debug message
The above sample log can be separated into 4 fields, each of which will take its respective value from here and will then be uploaded to Site24x7.
| Field name | Field value |
| DateTime | 2017-07-02 20:52:39,342 |
| LogLevel | DEBUG |
| SourceFileName | className |
| Line | 200 |
| Message | This is debug message |
