不带pidfile的Monit memcached配置

Question

我有典型的情况。需要为CentOS7上的memcached配置monit。问题是，我在谷歌找到的所有信息都包含了这一行：

check process memcached with pidfile /var/run/memcached/memcached.pid

但是，/var/run和/var/run/memcached文件夹中没有memcached.pid文件。我检查了/usr/lib/systemd/system/memcached.service

[Service]
Type=simple
EnvironmentFile=-/etc/sysconfig/memcached
ExecStart=/usr/bin/memcached -u $USER -p $PORT -m $CACHESIZE -c $MAXCONN $OPTIONS

因此，没有通向.pid文件的路径。问题是，我可以在没有.pid文件的情况下检查memcached吗？第二个问题--这个.pid文件能在另一个位置吗？

在monit配置中替换

check process memcached with pidfile /var/run/memcached/memcached.pid

使用

check process memcached with match memcached

我的memcached配置：

check process memcached with match memcached
    start program = "/usr/bin/systemctl start memcached"
    stop program = "/usr/bin/systemctl stop memcached"
    if failed host 127.0.0.1 port 11211 protocol MEMCACHE then restart
    if cpu > 70% for 2 cycles then alert
    if cpu > 98% for 5 cycles then restart
    if 2 restarts within 3 cycles then timeout

Centos 7，monit 5.14
