If you go to settings all settings look at polling engines what's the last DB update?

it doesn't seam to be a database problem..

I try this : https://support.solarwinds.com/SuccessCenter/s/article/Repair-a-failing-Job-Engine-Collector-and-Information-service-in-Orion-Platform (But with the lastest installation files "2019.4")

after I rerun the configuration wizard for (Services, WebSite and Database)

it was worst, I had lost the bandwidth utilization on my interfaces.

but after a reboot, now everything is working!

Do you know if this has to be applied across the entire Orion system, or only on the affected pollers? I have two pollers that are exhibiting the behavior, but these steps don't seem to be resolving my issue.

This is very often in some environments. when you didn't see any data collection but all pollers are up and showing ok with last DB update.

you also need to check the last DB update on Node summary page to verify this issue.

To resolve : Re-install job engine, collector and information service, & you are good with it.
