[IGN-5597]How to trend Perspective Sessions on a memory tag?

Ignition
1

We are currently trying to size our front-ends and load balancers based on active sessions. Really need a way to historize the perspective sessions of users. How do I accomplish this task?

Well, I figured it out. Just in case anyone else needs this info.

sessions = system.perspective.getSessionInfo()
tagPaths = ['tagpath to integer memory tag']
sessionslist = []
for users in sessions:
    sessionlist = users
    sessionslist.append(sessionlist)
count = len(sessionslist)
system.tag.writeBlocking(tagPaths, count)

Umm...if you are looking for the session count generally then just do

len(system.perspective.getSessionInfo())

If you have the EAM module, there's also a system tag automatically available.

Don't ask me why this particular thing requires the EAM module.

Ah wow! This is way easier, may just reference to this tag instead. Thanks!
