Check apply and transport lag of Oracle Data-Guard

Distribution: official part of Check_MK
License: GPL
Supported Agents: Linux, AIX

This check monitors the apply and transport lag time on an ORACLE database. You can set warn/crit levels in seconds for apply lag and transport lag.

The apply_lag_min is only useful when an apply lag is configured in Data Guard. Otherwise the apply lag is 0.

The init.ora-Parameter log_archive_config must be configured. Oracle Enterprise Edition is required for Oracle Data-Guard.

The Broker and Observer are automatically detected and monitored as well.

This check needs the Check_MK mk_oracle-plugin installed in the agent. Please refer to the online documentation for how to install that plugin.


The SID of the database in uppercase (as appearing in the process name of the pmon_... process).


No discovery supported.
