MongoClient::getHosts
(PECL mongo >=1.3.0)
MongoClient::getHosts — Updates status for all associated hosts
This extension that defines this method is deprecated. Instead, the MongoDB extension should be used. Alternatives to this method include:
설명
This method is only useful with a connection to a replica set. It returns the status of all of the hosts in the set. Without a replica set, it will just return an array with one element containing the host that you are connected to.
See the query section of this manual for information on distributing reads to secondaries.

반환값
Returns an array of information about the hosts in the set. Includes each host's hostname, its health (1 is healthy), its state (1 is primary, 2 is secondary, 0 is anything else), the amount of time it took to ping the server, and when the last ping occurred. For example, on a three-member replica set, it might look something like:
array(3) {
["A:27017"]=>
array(4) {
["host"]=>
"A"
["port"]=>
27017
["health"]=>
int(1)
["state"]=>
int(2)
["ping"]=>
int(369)
["lastPing"]=>
int(1309470644)
}
["B:27017"]=>
array(4) {
["host"]=>
"B"
["port"]=>
27017
["health"]=>
int(1)
["state"]=>
int(1)
["ping"]=>
int(139)
["lastPing"]=>
int(1309470644)
}
["C:27017"]=>
array(4) {
["host"]=>
"C"
["port"]=>
27017
["health"]=>
int(1)
["state"]=>
int(2)
["ping"]=>
int(1012)
["lastPing"]=>
int(1309470644)
}
}
