H1: Monitoring Slapd
|
|
|
|
Slapd supports a monitoring interface you can use to find out
|
|
many useful bits of information about what slapd is currently
|
|
doing, how many connections it has, how many threads are
|
|
working, etc. You can access the monitor feature by doing a
|
|
base object search of the SLAPD_MONITOR_DN from
|
|
include/ldapconfig.h with any kind of valid filter (e.g.,
|
|
"(objectclass=*)"). By default, this DN is set to "cn=monitor".
|
|
You will get one entry returned to you, with the following
|
|
attributes:
|
|
|
|
E: version: slapd <version> (<date>)
|
|
|
|
This attribute identifies the slapd server software by name,
|
|
version, and build date, e.g., {{EX: slapd 3.3 (Thu May 21 14:19:03
|
|
EDT 1996)}}
|
|
|
|
E: threads: <integer>
|
|
|
|
This attribute indicates the number of threads (operations)
|
|
currently outstanding in slapd.
|
|
|
|
E: connection: <fd> : <opentime> : <opsinitiated> :
|
|
E: <opscompleted> : <binddn> : [ <rw> ]
|
|
|
|
This multi-valued attribute summarizes information for each
|
|
open connection. The information given is {{EX: <fd>}}, the file
|
|
descriptor; {{EX: <opentime>}}, the time the connection was opened
|
|
in UTC format; {{EX: <opsinitiated>}}, the number of operations
|
|
initiated over the connection; {{EX: <opscompleted>}}, the number
|
|
of operations completed over the connection; {{EX: <binddn>}}, the
|
|
DN currently bound to the connection; and optionally {{EX: <rw>}},
|
|
indicating whether the connection is currently blocked for
|
|
read or write..
|
|
|
|
E: currentconnections: <integer>
|
|
|
|
The current number of connections.
|
|
|
|
E: totalconnections: <integer>
|
|
|
|
The total number of connections handled by slapd since it
|
|
started.
|
|
|
|
E: dtablesize: <integer>
|
|
|
|
The size of slapd's file descriptor table.
|
|
|
|
E: writewaiters: <integer>
|
|
|
|
The number of threads blocked waiting to write data to a
|
|
client.
|
|
|
|
E: readwaiters: <integer>
|
|
|
|
The number of threads blocked waiting to read data from a
|
|
client.
|
|
|
|
E: opsinitiated: <integer>
|
|
|
|
The total number of operations initiated by slapd since it
|
|
started.
|
|
|
|
E: opscompleted: <integer>
|
|
|
|
The total number of operations completed by slapd since it
|
|
started.
|
|
|
|
E: entriessent: <integer>
|
|
|
|
The total number of entries sent to clients by slapd since it
|
|
started.
|
|
|
|
E: bytessent: <integer>
|
|
|
|
The total number of bytes sent to clients by slapd since it
|
|
started.
|
|
|
|
E: currenttime: <UTC time>
|
|
|
|
Slapd's idea of the current time.
|
|
|
|
E: starttime: <integer>
|
|
|
|
The time slapd was started.
|
|
|
|
E: nbackends: <integer>
|
|
|
|
The number of backends currently being served by slapd.
|
|
|
|
E: concurrency: <integer>
|
|
|
|
Under Solaris 2.x only, an indication of the current level of
|
|
thread concurrency.
|
|
|
|
Note that slapd takes a snapshot of this information and
|
|
returns it to you. No attempt is made to ensure that the
|
|
information is consistent (i.e., if an operation thread is
|
|
modifying one of these things when the monitor thread is
|
|
reading it, strange results could be returned).
|
|
|
|
You should be able to use any LDAP client to retrieve this
|
|
information. Here's how you might do it using the
|
|
{{I: ldapsearch}}(1) client:
|
|
|
|
E: ldapsearch -s base -b cn=monitor 'objectclass=*'
|
