Beacon IIS HTTP error 404 logs "Default Machine Schedule.osd"

Level 6

Hi all,

I started monitoring IIS log at one of our beacons for HTTP errors and what is concerning me is that I'm seeing HTTP 404 error messages appearing every few minutes when FlexNet Agents are requesting "Default Machine Schedule.osd".

I tried switching in Beacon GUI back to local web server and then back to IIS but that didn't help. Anyone seen this and knows how to solve it?

Our installation is FNMS 2019R2 on-prem.

IIS Log:

2020-05-04 11:17:58 10.177.163.103 GET /ManageSoftDL/Schedules/Default+Machine+Schedule/Default+Machine+Schedule.osd - 80 - 10.185.145.216 FlexNet+Manager+Platform/13.1.1+(Windows+x86) - 404 0 0 140

BeaconIIS.log:

2020-05-04 06:17:58,582 [s.DownloadDLController] [WARN ] Requested file 'C:\ProgramData\Flexera Software\Staging\Common\Schedules\Default Machine Schedule\Default Machine Schedule.osd' not found.

 

Above record is from the same request, BeaconIIS log is in server time and IIS log is in UTC time zone.

 

Thanks!

Usually agents are getting the osd file from different folder with some generated GUID:

2020-05-04 11:37:22 10.177.163.103 GET /ManageSoftDL/Schedules/Default+Machine+Schedule+26E01C127ABB501658598FA2F3847162/Default+Machine+Schedule.osd - 80 - 10.179.162.34 Flexera+Inventory+Manager/13.1.1+(Linux) - 200 0 0 0

Oh, now I found that it's not only about Default Machine Schedule.osd but also InventorySettings.ndc file:

2020-05-04 11:43:21 10.177.163.103 GET /ManageSoftDL/InventorySettingsConfiguration/InventorySettings/InventorySettings.ndc - 80 - 143.166.135.175 FlexNet+Manager+Platform/13.1.1+(Windows+x86) - 404 0 0 31

but in few minutes the same address was reachable with HTTP 200 OK:

2020-05-04 11:43:40 10.177.163.103 GET /ManageSoftDL/InventorySettingsConfiguration/InventorySettings/InventorySettings.ndc - 80 - 10.161.31.244 FlexNet+Manager+Platform/13.1.1+(Windows+x86) - 200 0 0 15

Maybe the Beacon is reaching it's limits?

Below are logs from one Agent (10.177.163.103) requesting at three different times - first success, second error, third success. Why is that error happening?

Oh, for the last comment I believe the errors were caused by Beacon generating new files. I just found this in BeaconIIS.log (time 6:43 is same as 11:43 in IIS logs)

I starting to get a feeling that monitoring IIS log for 404 errors is useless...

Hi Pavol,

When agents request policy, they get a unique personalized policy. The agent policy file contains paths to various other packages (OSDs). The agent packages are created for a unique set of properties. Agents with same set of properties get the same package. E.G. agents part of same Inventory Groups get the same Default Failover Package, agents with same schedule(s) get the same Default Machine Schedule  package and so on. The Inventory Settings package is same for all agents.

When an agent requests a policy, Beacon evaluates its various set of properties and for each package, it checks if the files already exists, otherwise it creates the file, and then serves the policy.  When a Beacon downloads a new Beacon Policy file, it can affect agent's properties, hence Beacon deletes all the local packages and they are rebuilt when agents request their policies.

If the Beacon Policy file is updated between an agent requests the policy and Beacon updates its own policy file, then the agents may get a 404 error. In that case they try with other Beacons, while it is not guaranteed that other Beacons would have the package either. So the IIS errors you see may because the Beacon ran into that situation OR because another Beacon ran into that situation and agent is requesting this Beacon as a failover request.

To resolve, stop the Beacon webserver and delete the following folders at C:\ProgramData\Flexera Software\Staging\Common

  • Policies
  • InventorySettingsConfiguration
  • ClientSettings
  • ClientConfiguration
  • Schedules
  • Packages

And then restart the BeaconIIS. If possible, have an agent request the policy or just monitor the logs for some time:

  • mgspolicy -t Machine

When agent requests the policy, the BeaconIIS log shall show messages like "Writing package file" and you should not see an issue with packages it is creating. However if an agent requests a package, without actually requesting policy first, from this Beacon it may still throw a 404.

Hope that helps.
