# Housekeeping

{% hint style="danger" %}
For MongoDB log file, you should use the [logrotate](/dmk-mongodb/monitoring-and-maintenance/log_rotation.md) utility and not the `housekeeping.py` tool !
{% endhint %}

**dbi services** provides a cleaning script named `housekeeping.py` that performs several types of operations on log files.

* Deletion of old files
* Truncation of files
* Compression of old files
* Archiving of files (truncation + compression)

The script should be run as `housekeeping.py -c $MONGO_BASE/etc/housekeeping.conf`. You can find a template for the `housekeeping.conf` file in `$DMK_HOME/templates/etc/housekeeping.conf`.

#### Default settings

You can set default settings for the main operations with the `DEF` keyword:

{% code title="$MONGO\_BASE/etc/housekeeping.conf" overflow="wrap" lineNumbers="true" %}

```bash
DEF::DELET::100:: # Delete files older than 100 days
DEF::TRUNC::1000:: # Keep the last 1000 lines
DEF::ARCHI::1000:: # Backup the file and keep the last 1000 lines
DEF::COMPR::100:: # Compress files only if older than 100 days
```

{% endcode %}

#### Custom settings

You can define custom paths that you want to be cleaned with the `CST` keyword:

{% code title="$MONGO\_BASE/etc/housekeeping.conf" overflow="wrap" lineNumbers="true" %}

```bash
CST::/u01/app/mongodb/local/dmk/log/js/*.js::DELET::1:: # Delete JS files older than one day, to clean DMK internal folder.
```

{% endcode %}

{% hint style="danger" %}
For MongoDB log file, you should use the [logrotate](/dmk-mongodb/monitoring-and-maintenance/log_rotation.md) utility and not the `housekeeping.py` tool !
{% endhint %}
