Hi guys, just to let you know that for the last few days since starting to setup OSI PI using the documentation, documentation very seldomly loads, I am constantly facing the following scenario even after many page refreshes, this is on both Windows and Mac.
In addition in developer console you can see many errors, unsure if entirely related but believe it is.
Hope this information helps you resolve the issue.
I just emailed the team responsible for Live Library. Thanks for reporting that the issue is persisting!

Thanks for the images, particularly the 2nd one. The issue also affects us OSIsoft employees, so we are all in the same boat here.
No worries, glad to help.
Nice, i just noticed that when i have my developer tools open in Chrome, the LiveLibrary is much more responsive! It does throw the errors mentioned, but i have not been able to reproduce a failed load of an item...
Always nice, issues that disappear while debugging!
Now i did manage to capture an issue during Developer mode:
So that appears to generate internal server error (GET returns 500)
Thanks everyone for reporting back your experiences.
We have been working with our network team and are making some adjustments to our load balancer at 9am EST on Friday, 2018-10-12.
We'd love to hear your feedback to see if there is any change in the situation after that time.
It appears more reliable and a bit quicker, but still some 500 errors now and then:
Failed to load resource: the server responded with a status of 500 ()
AND
Refused to connect to 'http://livelibrary.osisoft.com/LiveLibrary/web/ui.xql?action=html&resource=publist_home.html' because it violates the following Content Security Policy directive: "connect-src 'self' *.osisoft.com *.test.osisoft.int api-osisoft.db-ip.com ".
AND
Hi Roger,
Please note that Timothy Martin announced the load balancer maintenance as future event: 9am EST on Friday, 2018-10-12
I didn't expect any change at the current time but am happy you already recognize an improved behavior
Ah, i skipped over the missing C in EST.... One small letter, one huge difference in time!
...and now started writing a loadtesting script to capture proper results...
Thank you Roger!
Hi guys, I am still finding the issue also and issues within dev console still remain:
Hi,
Looks like issue is not resolved. I am trying to open live library for an hour and it is still loading.
Thanks,
Mallesh
Hi all,
Our Network team has implemented a new potential fix, and is asking for feedback to see if it has had any positive impact. They changed the cookie persistence profile on our load balancer at 9am EST on Monday, 2018-10-22. Please let us know if you're still experiencing the issue after that time. Thank you your assistance. This issue may take us several rounds of troubleshooting, but we're committed to resolving it.
Thanks Tim. I'm getting good response times in all three browsers (IE11, Chrome, FF).
Too bad, but 500 error on the second click in the LiveLibrary:
VM441:1 GET https://livelibrary.osisoft.com/LiveLibrary/web/content.xql?c=t&pub=server-v11&lang=en&action=toc&format=html 500
Using Chrome
However, on a second try, all seems to work fine and fast. Let's see how this goes over time.
Did some more testing this morning, still got some 500 errors. E.g.:
/LiveLibrary/web/content.xql?c=t&pub=odbc-v3&lang=en&action=toc&docid=GUID-EF8AA010-ACFE-42B9-B0EB-EB6638C564C5:1 Failed to load resource: the server responded with a status of 500 ()
VM155:1 GET https://livelibrary.osisoft.com/LiveLibrary/web/content.xql?c=t&pub=odbc-v3&lang=en&action=toc&docid=GUID-28C45BEA-88C4-4C13-8470-BDC201EDF226 500
Hi Timothy,
For me it is working just fine in IE 11 (11.285.17134.0).
Chrome (69.0.3497.100), still reports some errors to console for certain JavaScript files and other resources like www.osisoft.com and www.youtube.com
Edge (42.17134.1.0) reports CORS and redirection errors with pub.xql
Firefox (62.0.3 64-bit) reports that loading was blocked due to a security policy.
This is when looking at the PI Server documentation. I see less to no errors e.g. with the AF SDK Reference which tells me some of the issues may be with the content itself or how it is offered.
It works well for me in Chrome - very responsive. This is probably the best that it has ever worked for me. In the past, clicking on a link in the search results in Live Library would usually result in a partially loaded page. Today it works very well!
Hi all, unfortunately we are still seeing this behavior.
Our network team believes they have isolated the problem and will continue running tests into next week.
Thank you to all of you that have reported back to us, and for your patience as we figure out how to resolve the issue.
This has been a long standing problem for myself and my colleagues. I am afraid I am still experiencing the problems today
Hi All,
Has this issue been resolved? It certainly doesn't look good at my end.
Regards,
Jaison Rodrigues
Hi Jaison,
I have tested the behavior with Chrome outside OSIsoft network and while I as well get some errors, it does not prevent the page from loading. I have also tested with IE 11 and one interesting thing is that IE appears way more relaxed on issues identified by Chrome. I am not trying to ease on the existing issues and hope Timothy Martin can share some additional information like what's done to fix those. We know that browsers behave differently and even we all have our personal preferences it sometimes helps to overcome issues by using a different browser and which browser works differs from web page to web page.
I don't like it either to switch between browsers but the best recommendation for now appears to try a different browser like IE 11.
Hi Gregor Beck, thanks for the update.
We have been continuously troubleshooting this issue with our network team. This week we were definitely able to rule out an issue with our load balancer.
Today we had a long TS call with our Live Library software vendor, and they are helping us analyze our logs. I'm hoping we are getting closer as this issue is affecting more than just page loading performance.
Hang in there everyone, we will get to the bottom of it. - Tim
My experience over the last few days is that the reliability definitly improved a lot. Where the failure rate was well above 75% before, it now is below 5%, so it's back to a usable state again.
On Chrome, still getting the occasional 500 error: VM195:1 GET https://livelibrary.osisoft.com/LiveLibrary/web/content.xql?c=t&pub=server-v11&lang=en&action=toc&format=html 500
On IE11, more or less the same results (i was not really looking forward to make IE11 the new benchmark of performance and reliability anyway).
On Edge, also more or less the same.
Thanks Gregor.
This looks like an intermittent issues. I had tested this earlier, when we received some updates in this thread from the users that it was working fine. It was working well for me but I started experiencing the same issue last week. I tried on Chrome and Edge browsers, but both gave me same results. The page didn't load.
I tried it today and it was the same but after refreshing it couple of times, it started to work.
Regards,
Jaison Rodrigues
Hi how are you the issue still seems the same from here, I have tried multiple pages today that constantly loaded, one of them was as follows: PI JDBC
Hi Jaison
I have just done a quick test here and it looks good.
Thanks,
John
I’m afraid that I am have these issues again with all browsers yesterday and today. It is very frustrating for us here
I too am having significant issues - it seems as bad as it was before.
Hi Adam,
For me the link you shared opens "Weather example: Create and populate PI points with weather data" within the PI Server 2016 R2 manual.
What browser are you using?
Can you try clearing all cookies from your browsers cache? Does that change the behavior?
By the way, are you accepting cookies?
I am seeing errors in the Console of recent Firefox and Chrome browsers but not in IE 11. Timothy Martin something appears not ok. Can you please check?
Unfortunately, we don't have a resolution at this time. The intermittent loading issue appears to be a vendor-related problem and we're investigating alternatives to the underlying software used for Live Library.
Our team knows this is still unresolved and I apologize for any frustration or inconvenience it may still be causing our users. I'm tagging our project manager and developer so they can see the latest comments.
Switching browsers may alleviate the issue. There are also PDFs of all of our product documentation available on the new Customer Portal at MyOSIsoft.com.
Gregor Beck thanks for tagging me.
Thank you Timothy Martin!
I conclude modern browsers are not always the best choice and summarize: OSIsoft LiveLibrary is currently best viewed with Internet Explorer!
Hi All, IT are aware of this issue. However, we still do not have a solution for this. Please use the workarounds advised by Timothy. You can try switch browsers or access product documentations from MyOSIsoft.com. Thank you.
Hi Adam, I agree, sometimes this does happen. It was covered in this thread but the problem is persisting.
