Versions of MySQL
VividCortex supports version 5.5 and above of MySQL, including MariaDB, Percona Server, and the most recent MySQL releases from Oracle. We also support Amazon RDS and Aurora for MySQL.
We cannot capture queries that are sent to the server by a Unix socket, shared
memory, replication, or any methods other than by the TCP network. If your
application connects to MySQL as
localhost, it will probably use one of these
non-supported connection protocols, and you should point it to a hostname or IP
address instead. A simple fix is to use
127.0.0.1, which will make the MySQL
client library connect via TCP instead of Unix socket.
We support Amazon RDS for MySQL by using an alternative method to capture queries.
Instead of decoding the network protocol, we can capture performance statistics from the
PERFORMANCE_SCHEMA tables, provided you’re using MySQL version 5.6.14 or newer.
Note that the
statements_digest consumer (table
setup_consumers) needs to be
for this to work and, if you want samples to be captured, the
events_statements_history_long consumers have to be enabled as well.
Note also that this approach is not exclusive to Amazon RDS. We can use it for any instance
where decoding traffic is not an option, like off-host installations and TCP connections using SSL.
We also support Amazon Aurora for MySQL, and the same
apply to Aurora instances as other Amazon RDS instances. In addition to supporting
an Aurora instance as a MySQL replica (i.e. replicating from a traditional MySQL
instance to Aurora), we also monitor the status of Aurora Replicas within an
Aurora cluster. This currently includes the server ID of the primary, the
number of replicas, and metrics on replica lag (average and max). When monitoring an Aurora cluster,
you will need to install the agent and monitor each node as a separate instance, using the instance
endpoints; do not use the general read/write endpoints.
Versions of PostgreSQL
VividCortex supports all commonly used, non-EOL versions of PostgreSQL. The oldest non-EOL version of PostgreSQL is currently 9.4.20. We also support Amazon RDS and Aurora for PostgreSQL.
We support both Citus and PgBouncer. To monitor PgBouncer, VividCortex must be installed using the local, on-host configuration.
W cannot capture queries sent on anything other than a TCP socket. Check your driver documentation for specific details on how to connect.
We support Amazon RDS and Aurora for PostgreSQL by using an alternative method to capture queries: we can take our metrics out of the
pg_stat_statements view, provided the
pg_stat_statements extension is installed and enabled.
Note that the
pg_stat_statements approach is not exclusive to Amazon RDS. We can use it for any instance where decoding the database network protocol is not an option, like off-host installations and TCP connections using SSL.
Versions of Redis
VividCortex supports Redis versions 2.0.0 and above, although versions prior to 2.6.0 will not report their full set of parameters. The agent will work regardless, but we may miss some configuration changes for older servers. We do not support Redis Sentinel instances.
Versions of MongoDB
VividCortex supports all generally available non-EOL MongoDB versions. Currently, the oldest non-EOL version of MongoDB is 3.2. For more information on MongoDB versions from the official documentation, please visit https://www.mongodb.com/support-policy.
We capture data from the
currentOp() command for versions which support it (3.2+).
We do not support Darwin (macOS), Solaris, Windows, or other non-Linux/FreeBSD platforms.
