Portal HA - Is there a url to check the status of machines to see which is primary/standby that doesn't require a token

AnthonyRyanEQL

Hi there,

I have an ArcGIS Enterprise 11.1 environment with Portal in HA inside AWS behind an ALB. My ALB routing for Portal is currently set to ONLY go to 1 machine (currently the primary) as defined by the target group in AWS. The reason for this setup is because I can't find a url that doesn't tell me the status of each machine to see who is primary or standby that doesn't require a token. I can't use the healthCheck endpoint as both machines will return {"status": "success"} as they are both functioning correctly.

This url requires a token https://<portal alb>/arcgis/portaladmin/machines/<portal machine>?f=pjson to work but gives me the information I need.

Has anybody come across this or come up with a workable solution?

Thanks

Jonathan,

I did have the security patch installed which was out on the 6th July 2023 and just saw the notice from 2 days ago about the bug. Thanks for the information. Looks like I'm sitting back until it's released.

Thanks

I have encountered this issue before and the solution was to present a simple custom web page which could handle a healthcheck request. One issue we saw in particular is that the ALB expects a 400 error (or similar) to fail-over but the error page(s) from portal or server would return 200 despite "the arcgis server is down" being the contents.

Why not just add both portal machines to the target group? Even though portal has a primary and standby concept, both machines can accept and respond to requests. There's no need for administrators to know which is primary and only send traffic to the primary.

Jonathan,

I originally did have both portal machines in the ALB target group but the machine with the secondary database kept failing requests so that's the reason I removed it from the target group and asked this question as i thought portal ha ran as active/failover. Now that I have a better understanding of Portal HA, I need to investigate why the second portal machine isn't processing requests, etc.

JonathanQuinn

Absolutely, that's a problem to address, not workaround. Did you recently patch the portals? There's a bug with patching an HA portal, specifically impacting the standby. The latest 11.1 patch is going to be re-issued to address the problem.

Jonathan,

Thanks

You can find that which machine is primary and which is secondary by going to the following URL Sign In with portal admin

https://webadaptorhost.domain.com/webadaptorname/portaladmin/machines

Thanks for the reply but this isn't what I was after. From above, I've already mentioned above that url and it requires a token (signed in) to be used so not really suitable with a ALB, etc and I have already accepted a solution.
