Enterprise Monitoring for RestcommONE – Part 3

In this post, the third in the series of posts in that subject (see previous posts and, I will show how to get the best picture of your application.

The metrics available will provide you insights for your application’s performance and efficiency and help you plan for high availability and disaster recovery.

Currently you will be able to get metrics from the following:

  • Jain Sip Stack for low level metrics such as ServerTransactions, ClientTransactions, Dialogs etc
  • Sip Servlet container metrics for metrics such as number of SIP responses for each response class, number of SIP messages etc
  • RestcommONE application for high level metrics such as number of live call sessions, sms sessions etc

Here is a screenshot of the dashboard you will get


You will see how to use these metrics to create useful dashboards using Graylog –

Graylog is an open source analytics platform that combines the best of the breed software and puts them together.

You have several options for how to install Graylog, for example OS packages for your Linux distribution of choice, chef and puppet scripts, virtual appliances as OVA images for virtualbox, vmware and docker. For more details you can check here

I won’t cover the Graylog installation here, but as a piece of advice, the Docker or Virtualbox image is the easiest way to go as a beginner.

Additionally you will need to install the Http Monitor Input Graylog plugin from here:

The Graylog version that I used for this tutorial is 1.2.2. You can check here for the Graylog documentation

Below you will find the list of metrics that are available:

  1. SIP Responses sent or received, for example 1xx-processed, 2xx-sent, 5xx-processed etc
  2. SIP Methods sent or receieved, for example bye-processed, invite-sent, ack-sent etc
  3. Active Sip Application Sessions and Sip Sessions
  4. Expired Sip Application Sessions and Sip Sessions
  5. Rejected Sip Application Sessions and Sip Sessions
  6. Sip Application Sessions and Sip Sessions per second
  7. Sip Application Session and Sip Session average alive time
  8. Sip Application Session and Sip Session maximum alive time
  9. RestcommONE total calls since startup
  10. RestcommONE total incoming calls since startup
  11. RestcommONE total outgoing calls since startup
  12. RestcommONE number of registered users
  13. RestcommONE number of live calls
  14. RestcommONE number of incoming live calls
  15. RestcommONE number of outgoing live calls
  16. RestcommONE number of Completed calls
  17. RestcommONE number of NoAnswered calls
  18. RestcommONE number of Busy calls
  19. RestcommONE number of Failed calls
  20. RestcommONE number of NotFound calls
  21. RestcommONE number of Canceled calls
  22. RestcommONE number of incoming SMS routed to clients
  23. RestcommONE number of incoming SMS routed to applications
  24. RestcommONE number of outgoing SMS
  25. JVM Metrics such as memory and threads in use

Jain sip stack and Sip Servlets provide JMX for the monitoring metrics but using the JBoss AS7 Http Management interface we can access these metrics over http in a nice json response.

There are two steps that needs to be done to enable the Jain sip stack and Sip Servlets metrics:

  • Add a JBoss management user. You can do this using the “” script which is located at $SIP_SERVLETS_HOME/bin (or $RESTCOMM_HOME/bin). For example you can create new user: adminUser adminPassword123$
    Username will be “adminUser” and password “adminPassword”
  • Edit the standalone-sip.xml file located at $SIP_SERVLETS_HOME/standalone/configuration/standalone-sip.xml ($RESTCOMM_HOME/standalone/configuration/standalone-sip.xml) and edit JBoss Management interface ip address:
    <interface name=”management”>
    <inet-address value=”${}”/>
    This IP Address must be reachable from the Graylog server.

Now the RestcommONE metrics are provided from the brand new Monitoring Service which is part of the REST API and you need no additional configuration. You will need a RestcommONE management user that is able to read the monitoring service metrics. Here I will use the default administrator user, “”.

[alert type=”notice”]Make sure you have successfully reset the administrators password the first time by login to the RestcommONE Admin UI (http://RESTCOMM_IP_ADDRESS:8080) .[/alert]

For easier setup I have provided Graylog content packs for the Inputs and Dashboard, that you can import and have everything set out of the box. You will only need to edit each Input to change the SipServlets (RestcommONE) IP Address and username/password.

You can find the Graylog content packs here:

To import the content packs, login to Graylog and go to System -> Content packs -> Import Content pack, then upload the relevant file. After you upload both files, you will have the content packs ready to be applied, so click one content pack and press Apply

Import And Apply Content Pack

Next step is to edit the imported Graylog inputs in order to provide the proper IP Address of Sip Servlets server, or RestcommONE, and username/password to be used. Go to System -> Inputs and edit one by one the three imported inputs. Additionally you can change the interval between requests for each of the inputs.

Edit Input 1/2

Edit Input 2/2

Now you can check the Dashboard that will be available after you imported the RestcommONE Dashboard content pack.


Last, the imported input content packs will provide you a lot of other metrics that you can add to the existing dashboard or create a new one.
