使用 Monit 在 Ubuntu 16.0.4 上监控 solr 服务

我试图弄清楚为什么我的 Monit ( https://mmonit.com/monit/ ) 似乎不想监视我的 Solr 服务。我已经为其余的服务工作了：

但由于某种原因，Solr 不想正确监控。

我按照这里的例子：

对于我的服务器，我对其进行了一些调整，因此服务是正确的，还有一些路径：

## Solr monitoring.

## Test the solr service.
check process solr with pidfile /var/solr/solr-8983.pid
  group solr
  start program = "/etc/init.d/solr start"
  stop  program = "/etc/init.d/solr stop"
  restart program  = "/etc/init.d/solr restart"
  if failed port 8983 then restart
  if 3 restarts within 5 cycles then timeout
  depends on solr_bin
  depends on solr_init

## Test the process binary.
check file solr_bin with path /opt/solr/bin/solr
  group root
  if failed checksum then unmonitor
  if failed permission 755 then unmonitor
  if failed uid root then unmonitor
  if failed gid root then unmonitor

## Test the init scripts.
check file solr_init with path /etc/init.d/solr
  group root
  if failed checksum then unmonitor
  if failed permission 744 then unmonitor
  if failed uid root then unmonitor
  if failed gid root then unmonitor

检查语法一切正常：

  monit -t
/etc/monit/monitrc:295: Include failed -- Success '/etc/monit/conf.d/*'
Control file syntax OK

关于我可以尝试什么的任何其他建议？

更新：我真的不明白为什么这不起作用。所有权限和文件似乎都存在，并且设置正确：

root@admin:/etc/init.d# ls -l /var/solr/solr-8983.pid
-rw-rw-r-- 1 solr solr 6 Jul 28 05:41 /var/solr/solr-8983.pid


root@admin:/etc/init.d# ls -l /etc/init.d | grep solr
-rwxr--r-- 1 root root 2711 Jul 25 13:25 solr

root@admin:/etc/init.d# ls -l /opt/solr/bin/ | grep solr
-rwxr-xr-x 1 root root 12694 May 29 22:36 install_solr_service.sh
-rwxr-xr-x 1 root root  1255 Mar  9 20:00 oom_solr.sh
-rwxr-xr-x 1 root root 72389 May 30 00:25 solr
-rwxr-xr-x 1 root root 66010 May 30 00:25 solr.cmd
-rwxr-xr-x 1 root root  6204 May 30 00:25 solr.in.cmd.orig
-rwxr-xr-x 1 root root  6950 May 30 00:25 solr.in.sh.orig

更新 2：重新启动 Monit 时，我在monit.log中得到了这个：
