There are few monitors that are only connected to the On-Prem station. These monitors turn red as soon as I activate the new station and disable the old station.
This is generally seen when you have an older On-Premise Monitoring Station and you installed a new version of the OPMS into the same group. Reason is there have been fixes and enhancements from the previous version to the current version.This can cause some problems especially with newer JMeter scripts. By separating them into different groups, this way we can separate the two OPMS stations from each other and use the latest version without any interference.
To get around this, perform the following steps:
1. Move the older version of the OPMS to another group by going to On-Premise -> Locations and selecting the location.
2. Set the latest version of the OPMS to active and then check a monitor against it.
