SODA Polling

[mjones]

I'll give a starting post with a little issue that we have been having.  The South Nation polling plan is SODA has been taking around 3 hours to poll all of our stations in the last week or so. The issue started to happen after I fixed/started polling a station that hadn't read any data in a couple months.  I tried to change the settings in my poll plan in the service section to read from the last 2 days up until now, instead of the last data point, but this did not fix the problem. 

Does anyone have any suggestions for how to make the polling plan faster?

Hi 'mjones',

I was going to reply to this matter via email - nice to see it was posted on this forum so I guess we can discuss here.

My first suggestion in resolving the slow retrievals was going to be review the poll plan settings - specifically, the time range settings to see if the service was going way back in time, attempting to grab values from months ago. It looks like you have ruled this out.

Next suggestion would be to check the Max. tries setting on each device connection in your plan.  Is it possible that the maximum try settings were accidentally set high on all or some of your devices?  If certain devices are failing and repeating 10+ times, your plan is going to take awhile to finish its cycle.

If you lower the 'Max. execution time' setting from 5 hours to something like 1 hour, will the plan finish before the hour is up?  I just wonder if this high setting is producing bugs or unwanted artifacts with the plan.  If you have to keep it this way so the plan finishes and all device data is obtained, I guess this wouldn't be an issue.

Have there been any internet service disruptions or known slowdowns with the gateway that SODA enters on at your site?

Just some thoughts.

Hi Curtis,

Thank you for the suggestions.  I incorporated them into my polling plan and this morning it ran a lot quicker.

Does anyone know why SODA polls data for my stations until 6:00am, but when I go into WISKI the stations only have data until 5:00am?  Why would there be an hour of data missing?  Thank you.

SODA publishes data with daylight savings time but WISKI is always in standard time.  I don't think there's a way to standardise them.

Thanks! My next question would be, how do I get SODA to poll the stations until the time I set it to?  I have it to poll at 7:00am every morning and it only polls the data until 6:10am.
