On a CRE-p16 instance with network scan support.
What is the max netmask it can scan with ?
I’ve had success with /8 subnet. Can you ping the IP addresses from the CMK server?
- On same CRE, I had a success to scan a smaller subnet and had 40 IPs discovered in 192.168.4.0/22 subnet.
Looks like it is using plain ping, not fping, to scan the subnet.
Is there a way to trigger a network scan manually,after I expand/shrink subnet range ?
Another /16 failed scan due to 110sec timed out.
not directly. But you can change the scan interval to 1 hour.
My trick was to delete the folder and re-create it
That’s also a possibility
just for information.
with version 1.6.0b1 fping dependencies were dropped. https://checkmk.de/check_mk-werks.php?werk_id=6188
I think the question now will be, how can one raise the 110sec network scan timeout setting ?
I successfully scanned a /16 network using 1.6.0p15.cee and 1.6.0p13.cre.
