By default, the desired state of an instance (backup or master) is determined by comparing a Keepalived's VRRP instance's current state to its intitial state. Use '-b' or '-m' to specify that an instance should be either in a backup state or a master state. If a weight is specified, an instance is assumed to be master if its effective priority (i.e. weight) is greater than or equal to the specified weight. The arguments '-b', '-m', and '-w' are incompatible.
The check returns the following codes:
Success (0): Keepalived is running and the desired state matches the current state.
Warning (1): Keepalived is running and the desired state is backup, but the current state is master.
Critical (2): Keepalived is not running or the desired state is master, but the current state is backup.
Unknown (3): SNMP agent is not responding, or invalid CLI options provided.
Specific instances can be monitored by using the '-i pcre' option and specific instances can be excluded by using the '-x pcre' option. The exclude option is processed after the include option. By default all instances are reported.
