How can I use Monit to monitor a service that does not have a /var/run/ pid file or how can I create a pid...
I am using Debian 9.8
I have a service that runs my dotnet program. I would like to monitor it with monit but in all of the examples, you need to reference a .pid file in /var/run but my dotnet program doesn't have a .pid file in /var/run.
So I added PIDFile=/var/run/testservice.pid to the .service file for my service but it does not create the file when I start it.
This is where I am at
this is my .service file
[Unit]
Description=Test Service
Wants=network-online.target influxdb.service
After=network-online.target influxdb.service
[Service]
User=testservice
Group=mainapp
SyslogIdentifier=testservice
PIDFile=/var/run/testservice.pid
Restart=on-failure
TimeoutStopSec=5
RestartSec=10
ExecStart=/usr/bin/dotnet /mainapp/app/TestSystemdService.dll
[Install]
WantedBy=multi-user.target
systemd pid monit

If all you want is to know whether the service is running, you can query systemd:
systemctl is-active TestApp.service
You can also check whether it is inactive specifically due to a known failure:
systemctl is-failed TestApp.service
According to docs, this can be incorporated into monit as check program … with path:
check program TestApp with path "systemctl --quiet is-active TestApp"
if status != 0 then ...
Note that systemd's PIDFile= is for telling init where to read the PID from. If the daemon itself doesn't create a pidfile, systemd certainly won't bother. If you really need one, you could have an ExecStartPost=/bin/sh -c "echo $MAINPID > /run/testapp.pid" or something similar.
