Script to check LDAP syncrepl replication state between two servers
This script check LDAP syncrepl replication state between two servers. One server is consider as provider and the other as consumer.
This script can check replication state with two method :
- by the fisrt, entryCSN of all entries of LDAP directory will be compare between two servers
- by the second, all values of all atributes of all entries will be compare between two servers.
In all case, contextCSN of servers will be compare and entries not present in consumer or in provider will be notice. You can decide to disable contextCSN verification by using argument --no-check-contextCSN.
This script is also able to "touch" LDAP object on provider to force synchronisation of this object. This mechanism consist to add '%%TOUCH%%' value to an attribute of this object and remove it just after. The touched attribute is specify by parameter --touch. Of course, couple of DN and password provided, must have write right on this attribute.
If your prefer, you can use --replace-touch parameter to replace value of touched attribute instead of adding the touched value. Use-ful in case of single-value attribute.
To use this script as an Icinga (or Nagios) plugin, use -n argument
A single couple of DN and password able to connect to both server and without restriction to retrieve objects from servers.
Usage: check_syncrepl_extended [options] Options: --version show program's version number and exit -h, --help show this help message and exit -p PROVIDER, --provider=PROVIDER LDAP provider URI (example : ldaps://ldapmaster.foo:636) -c CONSUMER, --consumer=CONSUMER LDAP consumer URI (example : ldaps://ldapslave.foo:636) -i SERVERID, --serverID=SERVERID Compare contextCSN of a specific master. Useful in MultiMaster setups where each master has a unique ID and a contextCSN for each replicated master exists. A valid serverID is a integer value from 0 to 4095 (limited to 3 hex digits, example: '12' compares the contextCSN matching '#00C#') -T, --starttls Start TLS on LDAP provider/consumers connections -D DN, --dn=DN LDAP bind DN (example : uid=nagios,ou=sysaccounts,o=example -P PWD, --pwd=PWD LDAP bind password -b BASEDN, --basedn=BASEDN LDAP base DN (example : o=example) -f FILTER, --filter=FILTER LDAP filter (default : (objectClass=*)) -d, --debug Debug mode -n, --nagios Nagios check plugin mode -q, --quiet Quiet mode --no-check-certificate Don't check the server certificate (Default : False) --no-check-contextCSN Don't check servers contextCSN (Default : False) -a, --attributes Check attributes values (Default : check only entryCSN) --exclude-attributes=EXCL_ATTRS Don't check this attribut (only in attribute check mode) --touch=TOUCH Touch attribute giving in parameter to force resync a this LDAP object from provider. A value '%%TOUCH%%' will be add to this attribute and remove after. The user use to connect to the LDAP directory must have write permission on this attribute on each object. --replace-touch In touch mode, replace value instead of adding. --page-size=PAGE_SIZE Page size : if defined, paging control using LDAP v3 extended control will be enabled.
