{% hint style="success" icon="lightbulb-on" %}
The log purge is done by the **`PurgeLogs`** automatic action.
{% endhint %}

{% hint style="info" %}
We advise you to purge your logs so as not to overload your instance and **avoid the keep** all option.
{% endhint %}

You can choose the first option **Change all** to setup all entries at once.

Each field allows you to delete, keep or delete after a certain period (between 1 and 120 months).

## Historical logs

### General

* **Add/update relation between items**
* **Delete relation between items**
* **Add the item**
* **Delete the item**
* **Restore the item**
* **Update the item**
* **Comments**
* **Last update**
* **Plugins** : retains or not the history of a plugin. For example, in the advanced dashboard, the history tab could be cleared.
* **Equipments refused by rules log** : Rules can be put in place to refuse equipment when an employee is working remotely, for example. This history can be cleared.

{% hint style="info" %}
An **item** is defined as anything that could be linked to a GLPI object (a contract, a document, a computer, etc.)
{% endhint %}

***

### Software

* **Installation/uninstallation of software on items**: add a new software
* **Installation/uninstallation versions on software**: adding a new version of an existing software package to a GLPI object. For example, adding version 7.4 of PowerShell to a computer that already has PowerShell installed
* **Add/Remove items from software versions**: This applies to **`Parc`** > **`Software`**. Multiple versions of the same software can coexist; here, we use OneDrive as an example. This option will clear the history of added versions from **`Parc`** > **`Software`** (without deleting the version itself, of course)
