The Windows agent uses caching features to enhance performance. The following types of data are persisted in the agent:
Users - Local, Domain, and Active Directory users
Groups - Global groups and Active Directory groups
OUs - Active Directory only
Password Hashes - Local, Domain, and Active Directory user passwords
It is important that you plan for the disk space needed to store this information in the agent. Use the following guide to calculate how much space is needed:
Users - 1 KB per user
Groups - 1 KB per group
OUs - 1 KB per OU
Password Hashes - 1 KB per 4 users
Other factors that affect caching storage space include numbers of events and the types of reports you are running. Additionally, if you manage endpoints by proxy, the number of managed endpoints affects the amount of disk space used.
In addition to the space reserved for caching information, the agent also uses the cache for temporary storage while processing reports and actions. The first time you run reports, the agent may require more time to collect data for the reports. In addition, it may take a few minutes for recently completed actions to be reflected in subsequent reports. The agent automatically cleans up this disk usage during normal processing. Allocate 20 MB of working space for the agent to use for normal processing.
