Failover configuration options reference
Configure these options in the opscenterd.conf file.
The location of the opscenterd.conf file depends on the type of installation:
-
Package installations: /etc/opscenter/opscenterd.conf
-
Tarball installations: install_location/conf/opscenterd.conf
Reference of available configuration options in opscenterd.conf for OpsCenter failover:
-
[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
Example non-default configuration
The default values for failover configuration can be adjusted for your environment requirements.
Open opscenterd.conf for editing and add a [failover] section:
[failover] heartbeat_period = 20 heartbeat_reply_period = 360 heartbeat_fail_window = 120 failover_configuration_directory = /myrsyncdir/opscenter/failover/ override_primary_redirect_url = https://opscenter:9999
The 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.
Restart OpsCenter after making configuration changes.
