Monitoring

Appliance resources can be monitored at a system-wide level. Exhaustion of any of the resources can have a negative impact on the speed of the transcription.

The following resources that can be monitored:

Here is an example GET request for the mem (RAM) resource:

curl -L -X GET 'http://${APPLIANCE_HOST}:8080/v1/management/resource/mem' \
    -H 'Accept: application/json' \
    | jq

Here is an example response:

{
    "rId": "mem",
    "percentage": 10.9,
    "value": 0,
    "intValue": 0
}

For advanced monitoring, a utility called Glances is available that runs on TCP port 3000. It allows real-time resource stats to be monitored on the Real-time Virtual Appliance. The easiest way to access this is via a web browser using the link http://${APPLIANCE_HOST}:3000/ in the address bar.

It is also possible to access the Glances API using XML-RPC or HTTP REST (for JSON output), for example:

curl -L -X GET 'http://${APPLIANCE_HOST}:3000/api/2/mem/percent' \
    -H 'Accept: application/json' \
    | jq

For more information on the HTTP REST interface, consult the Glances documentation.
