The determination of the number of service restarts metrics

[weiqiang333]

Currently monit_export grabs "up" and "checkStatus" two metrics
But can't get the information of pid change from it to determine the number of restarts
And, I found that to get the service pid will encounter different status pid information is null

I will try to achieve the capture of pid information.

It is worth reminding that the metrics value of monit_exporter_service_check will be in many combinations:
codes to text

//For conversion of status codes to text
$event[0] = 'OK';
$event[1] = 'Checksum failed';
$event[2] = 'Resource limit matched';
$event[4] = 'Timeout';
$event[8] = 'Timestamp failed';
$event[16] = 'Size failed';
$event[32] = 'Connection failed';
$event[64] = 'Permission failed';
$event[128] = 'UID failed';
$event[256] = 'GID failed';
$event[512] = 'Does not exist';
$event[1024] = 'Invalid type';
$event[2048] = 'Data access error';
$event[4096] = 'Execution failed';
$event[8192] = 'Changed';
$event[16384] = 'ICMP failed';
