# 6.8.4 Log & Monitoring

Each node has several services, each of which outputs information to Log files. After installing a node in the home directory of the platform (for example, DGT-Matagami), a «`dgt_clust`» directory appears, in which the working files of the corresponding node are stored. Each cluster and each node have their own working directory with an internal logs catalog, for example, 

«`.../DGT-Matagami/dgt_clust/c1/dgt1/logs`»:

If necessary, you can also connect an additional monitoring component based on Grafana/InfluxDb. The monitoring system extracts the information available to [a node](#user-content-fn-1)[^1]. To install it:

* Go to the Grafana service initialization directory «`.../DGT-Matagami/CORE/etc/Grafana`» and make the necessary settings in «grafana.ini», such as user and password settings (use admin/admin by default)
* Prior to installing and connecting a node (see [6.2](/dgt-docs/6.-administrator-guide/6.2-dgt-core-single-node-setup.md)), build and launch the Grafana service:

```
bash upDgtGrafana.sh
```

* Run a node with an additional =IDB key:

```
bash upDgtCluster.sh -G -SC -IDB -CB openssl 1 1
```

* Go to GRAFANA service (default port 3000)

```
http://[SERVER_IP]:3000
```

A typical output is shown in the figure below:

Grafana service uses the InfluxDB located in the «DGT-Matagami/Grafana/Grafana.db» directory. Database backup and restore is described in the [InfluxDB system manual](https://docs.influxdata.com/influxdb/v1.8/administration/backup_and_restore/).
