Coroner Server Advanced

If you are using a hosted version of coronerd, reach out to us to display additional histograms in the web UI. If you are using an on-premise version of coronerd, you'll need to complete the following steps to display additional histograms in the web UI:

Open /etc/coronerd/coronerd.conf on the coronerd machine.
In this configuration file, find the http-console object. Inside the http-console object, locate the columns object.
```
"http-console" : {
    "columns" : {
        "expand" : [
            "hostname",
            "application",
            "version",
            "dc"
        ],

        "list" : [
            "application",
            "version",
            "dc"
        ]
    },
}
```
The columns object contains two JSON arrays: expand and list. The elements in the list array are displayed on the project page. It is recommended to add any histograms you'd like to search for across error groups to this array. The elements in the expand array are displayed on the group page. It is recommended to add any histograms you'd like to view on a per-error basis to this array.
After updating the configuration, restart the coronerd service:
```
$ /etc/init.d/coronerd restart
```

Now you see the added histograms on the relevant pages.

Disable SSL

By default, coronerd is configured to encrypt traffic. If you are using a hosted version of coronerd, reach out to us to disable SSL. If you wish to turn off SSL on an on-premise version of coronerd, follow these steps:

Remove any relevant ssl sections in /etc/coronerd/coronerd.conf. You'll find ssl objects in the following JSON objects in the configuration file:

The read object in the listener object: The interface used to pull down snapshots.
The write object in the listener object: The interface used to submit snapshots.
http-console: The web interface.

Restart coronerd after every configuration change.
```
