Hi Victor,
Could you please update the NetXMS - so when there is a "data collection error" - this value to be recorded to the DCI where the error happens?
At the moment if i.e. checking connection on specific interval and the last value was that there was connection, but after that there is data collection error - the DCI remains the same old value - that there is connection and just stop updating. If you are using the NXSL for checking this DCI it will continue accepting the old value before the error (like everything is ok).
Thank you,
Boris
