The function healthCheckCli executes a single database health check pass and writes the information to an html format table. The output provided is the same as that returned by healthCheckcli().

There is no consistency between databases as to the information returned, as it is dependent on what information is publicly exposed by the database.

$perf = newPerfMonitor($db);
echo $perf->healthCheckCli();
