I have a requirement where i need to add certain ping operation to my message flows where any one can check whether the flow is up and running. anyone thru their browser can test whether the flow is running as they receive certain success message if the flow is up and running on their browser.
I have tried to add a operation to existing WSDL but as browser only supports HTTP Get method i was not able to implement it ( as i could see thru tcp-ip monitor).
I am using the SOAP node as input node for the message flow .
Any suggestions???

| Or is there any other alternative way where we can expose some ping functionality to the clients of the message broker?? |

I'm puzzled as to the real business critical reason for this.
Do you not trust broker to keep things running?
None of the clients/projects I've worked on have ever mentioned wanting something like this in the almost 9 years I've been using broker.

What will the end users do if the ping fails? Restart the broker? How many of them have the skill and the access?

And if you don't (like many people) why not monitor the broker like everyone else does? So that technical people with the correct skills and access can fix it?

| Actually this set of flows are developed for the development environment and just thought to add a functionality where they can know whether the flows are running or not to avoid number of queries from the fellow developers if the flow is down for some reason . and i agree with you that no one likes to add such functionality for the production. |

As an idea, why not create the correct aclentry (display) that would allow them to see the flow status in the toolkit? (/ toolkit proxy)

I've had to do this before...it does save some time cutting communication for a simple question.
Use the HTTPInput node in the same flow as the message flow you want to check. Then just create some reply to flow back with the HTTPReply node. Now anybody can just type a URL in their browser and they will get a response back if flow is up.
Not perfect, but it works 99% of the time.
Have fun

The SOAPInput node's execution group listener will accept an HTTP HEAD request to either '/' which means the execution group is "up" if you get a 200 reply or an actual URL, which means that at least one node is registered on that URL if you get a 200 reply or it returns a 404 which means no node has registered on that URL. As SOAPInput nodes "register" when they start you can use this to see if the flow is "up".
Kind Regards,
