We are getting the error Total number of concurrent checks exceeds 15, aborting frequently. Specially on below scenarioh:

When vCenter is in schedule maintanence. We are keeping all associated ESX host and vCenter services in Execution disable state. When we are enabling back then the error is generating. For bulk of services.

Can you please help on this.

Hello, the default maximum for concurrent checks is 15. This can be modified. You need to add the --concurrent_checks option to your command(s) for the plugin. Here's how:

Thank you!

Hi Brain,

Increasing concurrent check will not help because at a time we are getting 100 of alert with same message.

it actually will help - you need to edit it on every single check to add the variable @bolson mentioned.

the other option may be modifying it in your command definition.

@sgoffar, did @tacolover101's clarification help you? If so, are we ready to lock the thread?
