Data Collector Nodes (DCN) text color in Vtrin
The four DCNs we have will sometimes have blue text and sometimes have black text in Vtrin - please see screen shot below with Vtrin on left with black text and Vtrin on right with blue text. When the text is blue several option are grayed out. The same DCN, with the same user, will have different color text hours apart.
I cannot find anything in a manual that explains this.
Please point me to a manual or explain what causes the text in Vtrin to be blue or black.
