# Reading the Template Debug Logs

Each `Analytics Templated App Poller` log contains multiple log lines generated from different log events.

Multiple logs are written out during the templated app lifecycle of create, reset, or upgrade, usually 3–4 separate logs containing different details from the processing. Each log is a `Analytics Templated App Poller` log.

**note:** Each log entry has a 2-MB limit controlled by org limits and is truncated when the limit is exceeded.

The `Analytics Templated App Poller` log includes these details.

| Log Level | Apex Log Event              | Details                                                             | Example Log Line                                                                                                                                                                                                                                                                                                                                                                   |

Setting the `Wave` category log level to `Finest` includes all the log events in the log file.
