Supported Systems

VividCortex supports 64-bit Linux, FreeBSD and Windows on x86 processors, provided the platform meets the minimum requirements for Go. In particular:

  • CentOS/RHEL 5.x is not supported by Go, although we’ve had some success with more recent kernels (2.6.18-164 at least, but with a performance penalty up to 2.6.28; see this article for more information).
  • FreeBSD is supported for all non-EOL versions. See here for a list of supported versions.
  • Windows requires at least the first release of Server 2008.

We also support Containerized on Heroku using our VividCortex Buildpack. If you need support for a platform not listed here, please contact us to let us know your interest. You can email support@vividcortex.com, or chat with us by clicking the chat icon in the lower right corner of the screen. We may be able to accommodate your needs.

Versions of MySQL

VividCortex supports all versions of MySQL, including MariaDB, Percona Server, and the most recent MySQL releases from Oracle. We also support Amazon RDS for MySQL. VividCortex also supports logins created with old (pre 4.1) password hashes, though we do not recommend using these weak passwords because they are sent over the network in cleartext.

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 sniffing a TCP socket, 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 enabled for this to work and, if you want samples to be captured, the events_statements_history_long consumer has to be enabled as well. Note also that this approach is not exclusive to Amazon RDS. We can use it for any instance where sniffing is not an option, like off-host installations and TCP connections using SSL.

We also support Amazon Aurora for MySQL, and the same PERFORMANCE_SCHEMA instructions 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).

Versions of PostgreSQL

VividCortex supports all commonly used, non-EOL versions of PostgreSQL, and is designed to work reliably with any environment it discovers, so it should work with older versions as well, although we welcome your questions and comments about specific versions or other feedback you may have.

Just like for MySQL (see above), we 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 for PostgreSQL by using an alternative method to capture queries. Instead of sniffing a TCP socket, we can take our metrics out of the PG_STAT_STATEMENTS table, provided the pg_stat_statements extension is installed and enabled. Using this approach introduces an extra requirement, though: the user you provide for agents to authenticate with must be given superuser privileges (rds_superuser). Otherwise, agents would be unable to read queries from other users. This is a security feature in PostgreSQL; you can read more about it here.

Note that the PG_STAT_STATEMENTS approach is not exclusive to Amazon RDS. We can actually use it for any instance where sniffing 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. Agents will work regardless, but we may miss some configuration changes for older servers.

Versions of MongoDB

VividCortex supports all generally available non-EOL MongoDB versions. At this moment we do not track replication or sharding.

Unsupported Systems

At the time of writing, we do not yet support Darwin, Solaris or other non-Linux/FreeBSD/Windows platforms. Contact us if you need support for something specific; your input helps us prioritize.
