# Storage Times

The following defaults can be customized via the configuration file, with the following default values set: 

* Metrics (hosts/endpoints): 14 days 
* System events (hosts): 3 days 
* Network anomalies (hosts): 3 days 
* Audits (pentests): 90 days 
* Activity log: 6 months 
* PDFs: 1 year

{% hint style="warning" %}
If you customize a **configuration file** on the application server, you must always run **`setup.sh` afterwards**. Only then will the settings be applied.
{% endhint %}

Be sure to follow the JSON format. In case of problems, use a JSON validator to verify that the entire file is compliant.
{% endhint %}

1. Open the configuration file.

```
sudo nano /opt/enginsight/enterprise/conf/services/config.json
```

2. Add or adjust the values of the following `indexes` parameters to the **existing section** `database`. **The storage time is specified in seconds.** Leave the value of `uriConnectionString` as you find it in your `config.json`.

`database` without defined storage times:

```
"database": {
    "uriConnectionString": "%%MONGODB_URI%%"
  },
```

The extended section then looks like this:

```
 "database": {
    "uriConnectionString": "%%MONGODB_URI%%",
    "indexes": {
      "siemIncidents": {
        "ttl": 7776000
      },
      "siemExports": {
        "ttl": 2592000
      },
      "shieldLogs": {
        "ttl": 2592000
      },
      "hostFimLogs": {
        "ttl": 86400
      },
      "pentestAudits": {
        "ttl": 7776000
      },
      "endpointWebsites": {
        "ttl": 1209600
      },
      "hostMetrics": {
        "ttl": 1209600
      },
      "hostEvents": {
        "ttl": 259200
      },
      "hostNetworkAttacks": {
        "ttl": 259200
      },
      "history": {
        "ttl": 15552000
      },
      "reportsPDFs": {
        "ttl": 31536000
      }
      
    }
  },
```

3\. Save the configuration file (Ctrl+o) and confirm the saving process. Close nano (Ctrl+x).

4\. Navigate to /opt/enginsight/enterprise

```
cd /opt/enginsight/enterprise
```

5\. Update your installation for the changes to take effect.

```
sudo ./setup.sh
```
