Hello Cassey,

 

Please share your version of the pS software.

Are you able to observe a pattern of the issue (timewise)?

Do the systems automatically recover the flow of measurements?

OR What steps are required for the schedule to be recovered?

Do you have any specifics in your meschconfig-agent.conf file or are you using the defaults?

More specifically have you adjusted the interval parameters in the conf file?

 

Regards,

Ivan

Group,

 

     I mentioned it some time back, when I thought it was a problem with my 4 lower powered hosts running out of CPU, but I've been chasing it ever since and it's hitting my larger hosts as well.  Ever since I upgraded to 4.0 several months ago, I've had an issue where regularly, my hosts stop scheduling tests from the mesh.  My dashboard today shows a mess of hosts that failed to schedule tests last night some of them are on their second, (or more) continuous day.

 

     I can't figure out if this is a problem with the mesh config file or on the hosts (although since it's spread everywhere, even a newly installed CentOS7 host) I'm leaning toward some problem in the mesh config file.

 

     I'm not sure what to give you that will help, so below you'll find some diagnostic commands from an affected host this morning that is only running bandwidth tests, none of the latency tests scheduled.

 

Any ideas or help is appreciated.

 

Sincerely,

Casey Russell

Since the latency tests were never scheduled, I don't have anything from the API to show you, the mesh config file is at:
