Node status

STATUS

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

SHOW STATUS

SHOW STATUS [ LIKE pattern ]

SHOW STATUS is an SQL statement that displays a number of useful performance counters. IO and CPU counters will only be available if searchd was started with --iostats and --cpustats switches respectively (or they were enabled via SET GLOBAL iostats/cpustats=1).

An optional LIKE clause is supported. It lets you pick just the variables that match a pattern. The pattern syntax is that of regular SQL wildcards, that is, % means any number of any characters, and _ means a single character.

SQL:
SHOW STATUS LIKE 'qcache%';

SHOW AGENT STATUS

SHOW AGENT ['agent_or_index'] STATUS [ LIKE pattern ]

SHOW AGENT STATUS displays the statistic of remote agents or of a distributed index. It includes the values like the age of the last request, last answer, the number of different kind of errors and successes, etc. Statistic is shown for every agent for last 1, 5 and 15 intervals, each of them of ha_period_karma seconds.

SQL:
SHOW AGENT STATUS;

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).

SQL:
SHOW AGENT dist_index STATUS;
