go-check-plugins

The plugin handles AWS authentication in the following order of precedence:

1. Instance Profile: Uses the EC2 instance profile if available.
2. Environment Variables: You can configure AWS_PROFILE, AWS_ACCESS_KEY_ID, or AWS_SECRET_ACCESS_KEY within the env settings of your Mackerel agent configuration.

The check plugins follow a specification similar to Nagios and Sensu. The exit status returned by the plugin command determines the monitoring state in Mackerel:

The check-masterha tool provides three main subcommands to monitor different aspects of MasterHA:

• status: Checks the overall status (wraps masterha_check_status).
• repl: Checks replication status (wraps masterha_check_repl).
• ssh: Checks SSH connectivity (wraps masterha_check_ssh).

check-masterha status --all
check-masterha repl --conf /path/to/masterha_cluster.cnf
check-masterha ssh --conf /path/to/masterha_cluster.cnf
