7 | class Memcached extends CheckDefinition |

9 | public $command = 'service memcached status'; |
||
10 | |||
11 | public function resolve(Process $process) |
||
12 | { |
||
13 | if (str_contains($process->getOutput(), 'memcached is running')) || (str_contains($process->getOutput(), 'active (running)') ) { |
||
|
|||
14 | $this->check->succeed('is running'); |
||
15 | |||
16 | return; |
||
17 | } |
||
18 | |||
19 | $this->check->fail('is not running'); |
||
20 | } |

21 | } |
