|Oracle Directory Server Enterprise Edition Reference 11 g Release 1 (188.8.131.52.0)|
Server status, replication status, resource usage, and other monitoring information is available through DSCC.
cn=monitor, cn=ldbm database, cn=plugins, cn=config
dbName is the database name of the suffix that you want to monitor. Note that except for information about each connection, by default, the cn=monitor entry is readable by anyone, including clients bound anonymously.
The cn=monitor entry is an instance of the extensibleObject object class. For cn=monitor configuration attributes to be taken into account by the server, this object class, in addition to the top object class, is present in the entry. The cn=monitor read-only attributes are presented in this section.
Read-only monitoring information is stored under the cn=monitor entry.
DN for each Directory Server backend.
For further database monitoring information, refer to dse.ldif(4).
Number of bytes sent by Directory Server.
The number of bytes available for caching.
List of open connections given in the following format:
31 is number of the file descriptor used by the server in handling the connection
20010201164808Z is the date the connection was opened
45 is the number of operations received
45 is the number of completed operations
cn=admin,cn=Administrators,cn=config is the bind DN
Maximum number of simultaneous connections since server startup.
Number of current Directory Server connections.
Current time usually given in Greenwich Mean Time, indicated by GeneralizedTime syntax Z notation, for example 20010202131102Z.
Size of the Directory Server descriptor table.
Number of entries sent by Directory Server.
Number of Directory Server backends.
Number of Directory Server operations completed.
Number of Directory Server operations initiated.
The number of requests waiting to be processed by a thread. Each request received by the server is accepted, then placed in a queue until a thread is available to process it. The queue backlog should always be small, 0 or close to 0. If the queue backlog is large, use the nsslapd-threadnumber attribute to increase the number of threads available in the server.
Number of connections where some requests are pending and not currently being serviced by a thread in Directory Server.
Number of persistent searches currently running on the server. You can set a maximum number of persistent searches on the server by using the command dsconf set-server-prop max-psearch-count:number.
Directory Server start time.
Number of operation threads Directory Server creates during startup. This attribute can be set using the nsslapd-threadnumber attribute under cn=config. The nsslapd-threadnumber attribute is not present in the configuration by default, but can be added.
Total number of Directory Server connections.
Directory Server version and build number.
The cn=disk entry enables you to monitor disk conditions over LDAP. This entry is an instance of the extensibleObject object class. A cn=disknumber,cn=disk,cn=monitor entry exists for each disk. The following disk monitoring attributes appear under each of these individual disk entries.
Specifies the pathname of a directory used by the server on disk. Where several database instances reside on the same disk or an instance refers to several directories on the same disk, the short pathname is displayed. The disk numbering is arbitrary.
Indicates the amount of free disk space available to the server, in MB.
Note - The disk space available to the server process may be less than the total free disk space. For example, on some platforms a process that is not running as root may not have all the free disk space available to it.
Indicates the state of the disk, based on the available free space and on the thresholds set for disk low and disk full with the configuration parameters nsslapd-disk-low-threshold and nsslapd-disk-full-threshold. Possible values are normal, low, and full.
This entry holds counter information for the various subtree entry counter plug-ins, if they are enabled.
This entry holds counters related to the Class of Service plug-in. This entry is an instance of the extensibleObject object class.
When the CoS plug-in uses the hash table for fast lookup, if more than one classic CoS template corresponds to the hash key used, the plug-in next checks for matches in what is called the clash list, a list of templates sharing an identical hash key. The value of this attribute provides the average length across all hash tables of classic CoS template clash lists, giving some indication of how much linear searching the plug-in must perform after using the hash table during fast lookup.
The average number of clashes per hash table. That is, the average percentage per hash of classic CoS templates sharing an identical hash key.
The memory overhead in bytes to hold hash tables for fast classic CoS template lookups.
The memory in bytes used to hold hash values for fast classic CoS template lookups.
The number of classic CoS definition entries in use.
The number of hash tables created for fast lookup where more than 10 classic CoS templates apply for a single CoS definition. Hash tables are not created for smaller lists of templates.
The number of classic CoS template entries in use.
The number of distinct attributes with values calculated through CoS.
The number of indirect CoS definition entries in use.
The number of pointer CoS definition entries in use.
The number of pointer CoS template entries in use.
