▪️ Profiling and monitoring

The easiest way to see high-level information about your Manticore node is by running status in mysql client. It will show you information about different things:

current version
whether SSL is in effect or not
current TCP port/unix socket
uptime
number of threads
number of jobs in queue
number of connections (clients)
number of tasks being processed now
number of queries made since start
number or jobs in queue and number of tasks normalized by number of threads

You can specify a particular agent by its address. In this case only that agent's data will be displayed. Also, agent_ prefix will be used instead of ag_N_:

Finally, you can check the status of the agents in a specific distributed index. It can be done with a SHOW AGENT index_name STATUS statement. That statement shows the index HA status (i.e. whether or not it uses agent mirrors at all), and then the mirror information (specifically: address, blackhole and persistent flags, and the mirror selection probability used when one of the weighted probability strategies is in effect).
