TSIM: The Scheduled Iflows Monitor

TSMI (The Scheduled Iflows Monitor)

Note: This article is related to my previous post: CPI: Scheduling monitoring

The objective of this iFlow is to be able to present information related to the next scheduled executions of your iFlows. It is executed by a single http endpoint. The default url parameters are:

• daysAhead: 7 (Default) days of analysis.


• hourThreshold: Grouping for iflows with more than 6 (Default) executions per hour.


• mode: Execution mode ("artefacts" = raw information, "ts" = calculated cron expressions, anything else / default = render as web page)

Let's start with the sad part:

limitations and problems

• I couldn't find a better name for the Iflow. Fortunately this is simple to change. 🙂


• The web interface is heavy and can get slow due to the amount of records. It is based on TimelineJS, which was intended for journalism or blog articles.


• TimelineJS won't escalate well if you have several jobs or if they run to often. I'm still looking for ways to reduce the amount of displayed data.


• Due to the previous point, I grouped those Iflows with many entries (several times per hour). This is parametrizable. (And I'm sure this has to have some bugs)


• TimeZones. All calculations are done based on the server time. To change this adaptable to a user level, requires another parameter in the URL or some JavaScript to alter the Json at runtime. The second option seems better to me.

Installation

• Option 1: download the iflow from here -> GitHub


• Option 2 (manual): implements the following script and its Maven dependencies.

 

Execution

Simply open the configurable endpoint in your web browser:

Characteristics

• Zoom to Timeline


• Orange color: grouped scheduled executions.


• Purple color: individual scheduled executions.


• You can read the description of the cron entry... human readable!


• Link to the monitor of a specific iFlow


• It has a favicon and a logo 🙂

Closing Remarks

I hope this little iflow will help you to monitor using directly or as a reference to create a new one. If you have suggestions, leave them in the comments. Also, code updates and problem bug reports are welcome.

 

Enjoy!
