Users count, Machines Count, Tag Count

Ignition
1

Hi ,

I would like to display the below values in a vision window,

  1. Active OPC connections
  2. Users count from default user source.
  3. Users count for AD/Internal hybrid
  4. Parameters count that has been historized

would like to hear your ideas to retrieve the above info

Which version of Ignition?

For 2 and 3, do you want the total users in those sources or just the logged in users?

3

I am using 8.1.25.
I require total users count with specific role.

4

OPC connections or devices?

OPC UA connections as in Status-> Connections-> OPC Connections

from collections import Counter
from itertools import chain

# OPC connections
opcConnections = Counter([system.opc.getServerState(opcServer) for opcServer in system.opc.getServers(includeDisabled = True)])
print opcConnections

# user source
userSource = 'myUserSource'
users = system.user.getUsers(userSource)
roles = Counter(list(chain.from_iterable(user.roles for user in users)))
print roles

Thanks Jordan.
I have achieved the results by modifying the code as below,

	#To get the count of historized tag
	filters =	{
				'tagType'	: 'AtomicTag',
				'recursive'	: True
				}			
	provider = '[default]'
	historyCount = 0
	for tag in system.tag.browse(provider, filters).getResults():
		if 'history' in str(dict(tag).get('attributes', '')):
			 #print str(tag['fullPath'])
			 historyCount += 1
	vTotal = historyCount
	system.tag.writeBlocking("[.]Parameters",[vTotal])
	
	#To get the Total no of AD users
	userSource = 'XYZ.COM'
	users = system.user.getUsers(userSource)
	viewer_count = sum(1 for user in users if 'Viewer' in user.roles)
	system.tag.writeBlocking("[.]Users",[viewer_count])
	
	#To get the Total no of Local users
	userSource1 = 'default'
	users1 = system.user.getUsers(userSource1)
	viewer_count1 = sum(1 for user in users1 if 'Viewer' in user.roles)
	system.tag.writeBlocking("[.]Operators",[viewer_count1])	
	
	#To get the Total no of OPC connections
	from collections import Counter
	from itertools import chain
	
	# OPC connections
	
	opcConnections = Counter([system.opc.getServerState(opcServer) for opcServer in system.opc.getServers(includeDisabled=True)])
	connected_count = opcConnections['CONNECTED']
	system.tag.writeBlocking("[.]OPCConnections",[connected_count])
