Is there any hard limit on how many hosted or installed Collectors we may create within our Sumo Logic account? Is there any additional cost for creating these?
The maximum number of Collectors allowed per organization is 10,000 that includes both installed and hosted collectors.
Also, the cost of your subscription is based on the total volume of data expected to be sent by all of your Collectors to Sumo Logic, and the retention period set for the storage of the data received.
Creating new Collectors and Sources may add additional data volume to your account but as long as your total ingest and stored volume is below your contracted rate you will not see any additional charges.
