13.5. Monitoring Database Link Activity
It is possible to monitor the activity of database links from the command line using the
ldapsearch
command-line utility to return the monitoring attributes that are required. The
monitoring attributes are stored in the
cn=monitor,cn=
database_link_name,
cn=chaining
database,cn=plugins,cn=config
.
For example, the
ldapsearch
3
command-line utility can be used to retrieve the number of add
operations received by a particular database link. For example, this command monitors a database
link called
DBLink1
:
ldapsearch -h directory.example.com -p 389 -D "cn=Directory Manager" -w password -s sub -b
"cn=monitor,cn=DBLink1,cn=chaining database,cn=plugins,cn=config" "(objectclass=*)"
