Hi, i want to question about change polling methode from SNMP to Agent.
Can anyone tell me how we can change the polling method without delete historycal data?
Thank you
The message is kind of vague but what actually happens is that the node level data is still there, so things like cpu and memory history will usually continue without issue.
The part where you potentially lose data is that SNMP and WMI/Agent have very different ways of reporting on the data of child objects like volumes and interfaces. Solarwinds does not have a clean way to translate things across, and technically it wouldn't be true to try and show them as a continuous stream of data because the two sources arent always calculating things exactly the same way. So what happens is your interfaces and volumes will all turn grey and stop collecting new data, and you will need to use the List Resources button to make sure you add back in the equivalent agent/WMI based object. Then you would have two versions of each interface/volume that you monitor so you have to go to manage nodes and delete the old ones that are no longer getting data. Thats the part where you get data loss. Technically you could just leave the old interface or volume there if you really wanted to retain the historical data, but sooner or later you will want to clean it out as it tends to be clutter and confuses people when they see there are two versions of the same object.
