Some Trends Storing and other not storing
i face a big problem
in one node some trends are storing other not storing
and some trends storing for 2 min and then not storing
all the trends are in same history server but confusing alot
It could be many things but the first thing with history logging problems is always to restart the history services.
if you have redundant history logging ( and you should ) then stop one history service using the service configuration aspect ( untick the "enabled" setting ) wait for it to fully stop, then start it again ( tick the "enabled" setting ). Wait for the service to run again. This can take several minutes. Then stop and restart the history service On the other server.
if that doesnt resolve the problem, then you will need to post more information about what exactly is working and what isnt ( which nodes, what type of history, ttd logs etc )
