#WebAPI #Monitoring: We are on 7.11 cloud. We have developed WebAPIs and want to monitor them, by updating a database table. Thought of using executestoredprocedure fn from within WebAPI but the function does not support writes, it supports only reads ! Thought of using writer functions (bind() within load()) but it isn't working. Looks like, it works only from a saveInto or SAIL UI. Any ideas or thoughts on how can we update/write to a database table from within WebAPI expression in 7.11 ? Or should I consider that since WebAPIs in 7.11 support only GET method, therefore it is not possible to write/update database table ?

What are you trying to monitor with these writes? In 7.11, there are several logs that track performance of calls and other details that might meet your use case: forum.appian.com/.../Logging.html

Hi Justin, Thanks for the suggestion. Since we are on cloud, we can't have SPLUNK. Therefore, we write to an external database table which then gets splunk-ed. Splunk produces nice graphs/charts on how many times a service is called, no of failures vs successes etc and we can configure filters as well.

Have you looked into the Start Process Writer plugin? forum.appian.com/.../summary

Thanks Carlos, I did consider it. Thought of using writer functions (bind() within load()) but it isn't working. Looks like, it works only from a saveInto or SAIL UI, where there is some event (like button click or tab out etc) !!! I could not see any errors in log files and neither the process model was started !

That makes sense, actually. Another option might be to go back to the Exec SP plugin and modify it to allow inserts/updates.

Functions should not have side-effects, which is why the Exec SP function does not support write operations. See forum.appian.com/.../Custom_Function_Plug-ins.html for details.

Try user the Log Reader plugin to retrieve the built-in web api log. Run a process periodically that dumps the necessary details into your database.
