Failover configuration options reference
Configure failover options in the opscenterd.conf file, which is located at /etc/opscenter/opscenterd.conf for package installations, and at INSTALL_DIRECTORY/conf/opscenterd.conf for tarball installations.
edit opscenterd.conf, and then add a [failover] section.
The following example increases the default values, sets a custom directory location for failover configuration (package installation), and overrides the primary redirect URL with a non-standard port:
[failover]
heartbeat_period = 20
heartbeat_reply_period = 360
heartbeat_fail_window = 120
failover_configuration_directory = /myrsyncdir/opscenter/failover/
override_primary_redirect_url = https://opscenter:9999Restart OpsCenter after making configuration changes.
The following options are available:
-
[failover] heartbeat_period
How often OpsCenter should heartbeat to the backup. Default: 10 seconds.
-
[failover] heartbeat_reply_period
How often a backup OpsCenter should heartbeat to the primary Opscenter. Default: 300 seconds.
-
[failover] heartbeat_fail_window
The amount of time required before a lack of heartbeat triggers failover. Default: 60 seconds.
-
[failover] failover_configuration_directory
The directory where failover specific configuration is stored. This directory should not be mirrored/replicated across OpsCenter installs when configuring OpsCenter to support failover. The default location is
/var/lib/opscenter/failover/for package installations andinstall_location/failover/for tarball installations. -
[failover] override_primary_redirect_url
If set, overrides the primary OpsCenter URL automatically generated during failover.
Example:
https://opscenter:80
