I have got a quite big installation with >900 devices with 8000 Sensors (mainly 60 second interval), which feels very slow.
These devices are more or less distributed over several remote probes for performance but also security reasons (some are in DMZ). Now I want to have a view for e.g. a Helpdesk agent on certain sensors only. (Mainy Ping sensors, some Sensor Factory (for showing state of a cluster)).
I started using the libraries with the collection option to show only certain filters. So I bound the whole PRTG object to each of the sub nodes and filter based on tags/priority etc. on the sub nodes. (Sub nodes represent different customers or Locations or other logical summaries).
Now I have read "Avoid Libraries" in http://kb.paessler.com/en/topic/2733-how-can-i-speed-up-prtgespecially-for-large-installations which makes me a bit nervous, as I am going to add a whole bunch of sub nodes etc. to one of my libraries, as I am still missing about 100 locations e.g.
Is there another best-pratice approache to filter certain information to a specific user group? I want the Helpdesk just to see Status sensors, but for example no SNMP Traffic Sensors. But in addition I need to be able to make it unterstandable for them, as e.g. Devices of the same logical group may be splitt to 2 different Probes (so in the Device view would be separated).
In addition to the above, I found out that the libraries seem to use my credentials somehow to update. (I copied the config to another system where my default user was not on and got the failed login slow down message..)
I would be happy to receive some thoughts on best practices. Lars
