111ab8f5e4 MXS-2441: Document galeramon changes
Added a section that describes how galeramon behaves when it is configured
to monitor non-Galera servers that are replicating from Galera nodes.

8b29e70f63 MXS-2428 Allow fixed Clustrix configuration
If 'dynamic_node_detection' has been set to false, then the
Clustrix monitor will not dynamically figure out what nodes are
available, but instead use the bootstrap nodes as such.

With 'dynamic_node_detection' being false, the Clustrix monitor
will do no cluster checks, but simply ping the health port of
each server.
2019-04-16 13:58:27 +03:00
e09a6c8100 MXS-2428 Add 'dynamic_node_detection' 'health_check_port'
'dynamic_node_detection' specifies whether the Clustrix monitor
should dynamically figure out what nodes there are, or just rely
upon static information.

'health_check_port' specifies the port to be used when perforing
the health check ping.

f8a22d0ac0 MXS-2344 Add setting for enabling SSL for replication
If the monitor setting "replication_master_ssl" is set to on, any CHANGE MASTER TO-command
will have MASTER_SSL=1. If set to off or unset, MASTER_SSL is left unchanged to match existing
behaviour.

858327acf7 Rename Being Drained to Draining
With this, the words are unique and can be searched for more easily. This
does not fix the test failure of mxs2273_being_drained.

45ba520057 Update csmon documentation
The required functionality for automatic "master" detection is in 1.2.

b07c53d532 Remove multi-master monitor
Was deprecated in 2.3. Similar features are in MariaDB-Monitor.

One system test was modified to use MariaDB-Monitor instead. Some parts
of the test are disabled for now to make it pass.

b582119d27 MXS-2275 Check for softfailed nodes
When checking the node info, also include information about wheter
a node is being SOFTFAILed. If it is, turn on the `Being Drained`
bit.

A node is SOFTFAILed with the intention of removing it, so better
not to create new connections to it as they later would be broken
when the node is actually taken down.
2019-02-01 11:00:53 +02:00
cb07687672 MXS-2275 Implement [un]softfailing
It is now possible to [un]softfail a Clustrix node via MaxScale
using a Clustrix monitor module command.

In case a node is successfully softfailed, the `Being Drained` bit
will automatically turned on. Similarly, if a node is successfully
unsoftfailed, the `Being Drained` bit will be cleared.

89c059411d MXS-2219 Add health check threshold
Make it configurable how many times a node may fail to respond
on the health check port before it is considered to be down.

656b3e60f6 Deprecate mmmon and ndbclustermon
Separated mmmon and ndbclustermon from the list of supported modules into
their own legacy section. Added a warning about the deprecation to the
relevant documents.

Also added the csmon link to the documentation contents.

operations in general and fixes errors.
2018-09-21 10:54:36 +03:00
cb54880b99 MXS-1937 Cleanup event handling
Event handling is now enabled by default. If the monitor cannot query the EVENTS-
table (most likely because of missing credentials), print an error suggesting to
turn the feature off.

When disabling events on a rejoining standalone server (likely a former master),
disable binlog event recording for the session. This prevents the ALTER EVENT
queries from generating binlog events.

Also added documentation and combined similar parts in the code.
