Dear Board Members
I have a redundant ignition server setup and would like to display an alarm if one of the nodes if offline
I didn’t find anything in ignition to check the redundancy state to create an alarm.
my idea now was to check if the webpage of the other node is available using python.
However when i run the following code it complains about the HTTPConnection part in the code
import httplib conn = httplib.HTTPConnection("www.python.org") conn.request("HEAD", "/") r1 = conn.getresponse() print r1.status, r1.reason
My question is: is the python library complete in ignition or are bits missing.
Has anyone another idea of solving my problem.
I did try the ping route through java but firewall is blocking this even when ICMP is in the exception list.
Thanks in advance guys
P.S.: it would be nice to have a system tag available to show other redundant nodes configured and to see if they are active.
