You've got multiple subnets in your network and created an IP Range scanning target for each one.
Excited to witness Lansweeper's capabilities, you've added all the targets. The results are coming in, and everything seems to function correctly.
You continue to add other scanning targets to discover the full potential of Lansweeper, but you're noticing a slowdown or clog in the scanning process.
What happened?
By default, every day at 12 pm (local scanning server time), all IP Range scanning targets are scheduled to be scanned automatically.
If you have several of these targets, Lansweeper's scanning service will be busy for a significant amount of time every day at noon. When setting up IP Scanning targets, it's easy to overlook the scheduling options for each target you create.
Now what?
To reduce the likelihood of a heavy load, it is recommended to reschedule the IP Range scanning targets to start at a different time of day. However, if you have numerous IP Range scanning targets set up in Lansweeper, rescheduling them individually can be a tedious task. Fortunately, you can use a script to automate the process and let the computer do the heavy lifting.
The script below will randomize each IP Range scanning target:
DECLARE @IPrangeID int
DECLARE MY_CURSOR CURSOR
LOCAL STATIC READ_ONLY FORWARD_ONLY
FOR
SELECT DISTINCT IprangeID
FROM tsysIPScanRanges
OPEN MY_CURSOR
FETCH NEXT FROM MY_CURSOR INTO @IPrangeID
WHILE @@FETCH_STATUS = 0
BEGIN
update tsysipscanranges set
Day1time = CONVERT(DATETIME, RAND())
where iprangeID = @IPrangeID
PRINT @IPrangeID
FETCH NEXT FROM MY_CURSOR INTO @IPrangeID
END
CLOSE MY_CURSOR
DEALLOCATE MY_CURSOR
update tsysipscanranges set
Day2time = Day1time,
Day3time = Day1time,
Day4time = Day1time,
Day5time = Day1time,
Day6time = Day1time,
Day7time = Day1time
update tsysupdate set IpScanRanges = getdate()
Your IP Range scanning targets will now be scheduled to run throughout the day for better organization and efficiency.
