Solaris utilities such as vmstat and iostat provide an overall assessment of the health of the system. To get a better understanding of what is going on with the directory itself, the iPlanet Directory Server includes some performance monitoring tools.

These tools are explained here.. Monitoring Resources The following table s show available performance monitoring parameters of three categories: overall server performance (TABLE 10-1), current resources being consumed (TABLE 10-2), and the status of current connections (TABLE 10-3).. Solaris and LDAP Naming Services TABLE 10-1 Resource Server Performance Monitoring Usage Since Startup Average/Minute Connections Total number of connections to this server since server startup. Average number of c none none onnections per minute since server startup. Average number of operations per minute since server startup..

Operations initiated Total number of ope none for none rations initiated since server startup. Operations include any client requests for server action, such as searches, adds, and modifies in the directory tree. It is likely that multiple operations will be initiated for each connection.

Total number of operations completed by the server since server startup. Operations completed Average number of o none none perations per minute since server startup. Average number of entries sent to clients per minute since server startup. Average number of bytes sent to clients per minute since server startup.

. Entries sent to clients Total number of ent none none ries sent to clients since server startup. Entries are sent to clients as the result of search requests. Total number of bytes sent to clients since server startup.

. Bytes sent to clients TABLE 10-2 Resource Current Resource Usage Table Current Total Active threads Current number of a none for none ctive threads used for handling requests. Additional threads can also be created by internal server tasks, such as replication. Total number of open connections.

Each connection can account for multiple operations and, therefore, multiple threads. Total number of remaining connections that the server can concurrently open. This number is based on the number of currently open connections and the total number of concurrent connections that the server is allowed to open.

Current Total Threads waiting to write to client Total number of thr eads waiting to write to the client. This happens anytime the server must pause while sending data to a client. Reasons for this pause can include a slow network or client, or an extremely large amount of information being sent to the client.

Total number of threads waiting to read from the client. Threads wait if the server starts to receive a request from the client and the transmission of that request is halted for some reason. Generally, threads waiting to read are an indication of a slow network or client Number of threads running concurrently.

Total number of databases being serviced by the server. Currently, this value is always 1..

The number of operations initiated by this connection. The number of operations completed by the server for this connection.

The distinguished name used by the client to connect to the server. If the client has not authenticated to the server, the server displays the error code not bound in this field. The state of the server currently blocked (or not) for read or write access to the client.

Possible values include: Not blocked The server is idle, actively sending data to the client or actively reading data from the client. Blocked 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.

Click the Server tab. 3. To continually refresh the screen with new data, check the Continuous refresh check box.
