Description
Indicates whether the server is currently blocked for read or write access to
the client. Possible values include:
• Not blocked. Indicates that the server is idle, actively sending data to the
client, or actively reading data from the client.
• Blocked. Indicates that the server is trying to send data to the client or
read data from the client but cannot. The probable cause is a slow
network or client.
Description
Indicates the number of times the server could process a request by
obtaining data from the cache rather than by going to the disk.
The total number of requests performed on your directory since server
startup.
The ratio of cache tries to successful cache hits. The closer this number is to
100%, the better.
Indicates the number of pages read from disk into the cache.
Indicates the number of pages written from the cache back to disk.
Indicates the number of read-only pages discarded from the cache to make
room for new pages. Pages discarded from the cache have to be written to
disk, possibly affecting server performance. The lower the number of page
evicts the better.
Indicates the number of read-write pages discarded from the cache to make
room for new pages. This value differs from Pages Written Out in that these
are discarded read-write pages that have not been modified.
Pages discarded from the cache have to be written to disk, possibly affecting
server performance. The lower the number of page evicts the better.
