ChatGPT is your friend.
Taking this a step further, you could expand this to run every N seconds and update LM when there’s a change. This makes use of my lmwrapper and the SDK to make the code simple. You could run this on one of your collectors assuming python is installed. You’ll need to get the website_id of the website that needs to be updated. This can be found by going to the website in UIv4 (shock!) and getting the URL when the desired website is selected. My URL looks like this:
/santaba/uiv4/websites/treeNodes#websiteGroups-1*,websiteGroups-60,websiteGroups-174,websites-113
Where 113 is the ID of the website I am looking at in the UI.
import socket
from time import sleep
from lm import lm
# this is the number of seconds between checks of the DNS record
n = 30
# this is the ID of the website in LM to update
website_id = 123456789
# this is the FQDN of the target
fqdn = "easypost.com"
existing_ip = ""
# start an infinite loop (Ctrl+C to exit)
while True:
# resolve the DNS name to IP
try: current_ip = socket.gethostbyname(fqdn)
# do this if there's an issue resolving the DNS
except socket.gaierror as e: print(f"Error resolving the DNS for {fqdn}: {e}")
# if the IP we got during the last cycle is different from the IP we got on the previous line, we need to update LM
if existing_ip != current_ip:
# update LM
response = lm.patch_website_by_id(website_id, {"host": current_ip})
# as long as the update was successful, remember the new IP as the current IP
if response: existing_ip = current_ip
# what to do if there's an error updating LM
else: print("There was an error updating the website.")
# wait N seconds before doing it all again
sleep(n)
That’s about as plug and play as you’re going to get.
