6.22.1 Environment variables for commands that are executed from HA Monitor

The following table lists the environment variables that are applied when a user-created command is executed.

Table 6‒22: Environment variables applied when a command is executed
No.	Command	Environment variable
1	User command (changing the status of HA Monitor)	Starting HA Monitor (`monstart` command) RHEL 6 or earlier: Environment of the user who executes the `monstart` command RHEL 7 or later: Execution environment for systemd
1	User command (changing the status of HA Monitor)	Starting HA Monitor (automatic startup) RHEL 6 or earlier: Execution environment for init RHEL 7 or later: Execution environment for systemd
2	User command (changing the status of the server)	Execution environment when HA Monitor is started (same as item 1)
3	Server start command	Execution environment when HA Monitor is started (same as item 1) Note that the environment of the user who executed the `monbegin` command applies in the following cases: The `monbegin` command is executed to start the active server. The server that was started as the standby server by executing the `monbegin` command is started as the active server when hot-standby switchover occurs.
4	Server termination command	Execution environment when HA Monitor is started (same as item 1)
5	Server monitoring command	Execution environment when HA Monitor is started (same as item 1)

The environment variables that are applied depend on how HA Monitor is started and when the command is executed. Therefore, specify the necessary operating environment variables in the command.
