Pico

/EC

*

This dropdown shows the running Picos/EC to fetch logs from. This field cannot be left blank. The *pico field filters capture logs from both platform-level and application-level components, as they all operate within the Pico framework. As a result, applying filters like Platform, EC, or Transport may include logs from related services, such as Derby or Execution Contexts, due to their interaction with the core platform.

Note!

For each selected Pico, a request will be sent to that Pico to list all files in a specific folder. If you select Picos in bulk, the response time might be slow depending on the network of each Pico.

Date Range

Define a range of dates to display log entries for. A few predefined options are available. If no date range is defined, all entries are displayed. The default date range is set to Today. The available options are:

  • User-defined

  • All

  • Last hour

  • Today

  • Yesterday

  • This week

  • This month

If you select User-defined, enter the Start date and time and End date and time.
