# Check dnl\_softswitch log

The location for dnl\_softswitch log is as follows:

> /opt/denovo\_v6/dnl\_softswitch/log/dnl\_softswitch.log

If your dnl\_softswitch is started successfully, you should see the following lines inside this log:

```
2022-12-28 08:57:37  [NOTICE] routing_data.c:11516 Loading table rate data done
2022-12-28 08:57:37  [NOTICE] routing_data.c:11518 Loading table rate done, elapsed 0(s), loaded 1 records
2022-12-28 08:57:37  [WARNING] routing_data.c:11634 ********** All data loading done **********
2022-12-28 08:57:37  [WARNING] routing_data.c:11638 ********** dnl_softswitch Started **********

```

If you see error such as the following, you should go to the config file and modify the correct IP where postgres is listened on:

```
2022-12-28 08:57:10  [NOTICE] dnl_shaken.c:1615 SHAKEN status thread: couldn't connect to the database!
2022-12-28 08:57:11  [WARNING] dnl_call_qos_report.c:326 DB connect failed, PQstatus:1, connection to server at "154.27.74.199", port 5432 failed: Connection refused
	Is the server running on that host and accepting TCP/IP connections?
```

The path for dnl\_softswitch config is as follows:

> /opt/denovo\_v6/dnl\_softswitch/conf/dnl\_softswitch.conf

To check the IP for your postgres instance, you can use the following command:

```
[root@switch01 log]# netstat -anp |grep postgres
tcp        0      0 127.0.0.1:5432          127.0.0.1:56800         ESTABLISHED 1885/postgres: webb 
tcp        0      0 127.0.0.1:5432          127.0.0.1:49280         ESTABLISHED 2286/postgres: webb 

```

Inside the dnl\_softswitch.conf, you can find the \[db] block to modify the postgres IP accordingly:

```

[db]
db_host = 127.0.0.1
db_listen_port = 5432
db_name = class4_dnl
db_user = class4_user
db_user_password = 123456


```
