  • not-found: The netgroup could not be found.

  • abandoned: The cache entry has been abandoned.

  • Total number of hosts in the netgroup cache: The number of host names retrieved from the name service in mapping the netgroup to a list of hosts.

  • How long it took to expand the netgroup: How long it took to expand the netgroup the last time in the queue.

  • Entry is refreshing: If the entry is a complete miss or refresh.

  • Next refresh time: When the next refresh is scheduled to take place.

  • Netgroup by host state: Boolean state indicating if netgroup-by-host feature is used for resolving netgroup membership check.

  • Number of IP addresses cached: Number of client IP addresses that are matched for the netgroup. The count includes both positive and negative results.
