# Logs and errors (Integration) components
| [tAssert](https://help.qlik.com/talend/r/en-US/7.3/components/logs-and-errors/tassert) | Generates the boolean evaluation on the concern for the Job execution status and
provides the Job status messages to tAssertCatcher. |
| --- | --- |
| [tAssertCatcher](https://help.qlik.com/talend/r/en-US/7.3/components/logs-and-errors/tassertcatcher) | Generates a data flow consolidating the status information of a
job execution and transfer the data into defined output
files. |
| [tChronometerStart](https://help.qlik.com/talend/r/en-US/7.3/components/logs-and-errors/tchronometerstart) | Operates as a chronometer device that starts calculating the
processing time of one or more subJobs in the main Job, or that
starts calculating the processing time of part of your
subJob. |
| [tChronometerStop](https://help.qlik.com/talend/r/en-US/7.3/components/logs-and-errors/tchronometerstop) | Operates as a chronometer device that stops calculating the
processing time of one or more subJobs in the main Job, or that
stops calculating the processing time of part of your subJob. tChronometerStop displays the
total execution time. |
| [tDie](https://help.qlik.com/talend/r/en-US/7.3/components/logs-and-errors/tdie) | Triggers the tLogCatcher component for exhaustive log before
killing the Job. |
| [tFlowMeter](https://help.qlik.com/talend/r/en-US/7.3/components/logs-and-errors/tflowmeter) | Counts the number of rows processed in the defined flow, so this number can be caught
by the tFlowMeterCatcher component for logging
purposes. |
| [tFlowMeterCatcher](https://help.qlik.com/talend/r/en-US/7.3/components/logs-and-errors/tflowmetercatcher) | Operates as a log function triggered by the use of a tFlowMeter component in the Job. |
| [tLogCatcher](https://help.qlik.com/talend/r/en-US/7.3/components/logs-and-errors/tlogcatcher) | Operates as a log function triggered by one of the three: Java
exception, tDie or tWarn, to collect and transfer log
data. |
| [tLogRow](https://help.qlik.com/talend/r/en-US/7.3/components/logs-and-errors/tlogrow) | Displays data or results in the Run console
to monitor data processed. |
| [tStatCatcher](https://help.qlik.com/talend/r/en-US/7.3/components/logs-and-errors/tstatcatcher) | Gathers the Job processing metadata at the Job level and at the component level and
transfers the log data to the subsequent component for display or storage. |
| [tWarn](https://help.qlik.com/talend/r/en-US/7.3/components/logs-and-errors/twarn) | Triggers a warning often caught by the tLogCatcher component for
