5. install services

To ensure that all VIMON components run consistently, they must be integrated as services.

Set up Services under Linux

Both of the following variants use the set configuration to start all relevant Services in the correct user context.

Under Linux, the Services to be started must be activated under ../vimon/config/services/service_config:

Edit the file service_config and set all desired Services to true which should run on this server.
Example:
Implement either init.d or Register service (recommended).

Register service

It is possible to integrate the service file ../vimon/services/vimon.service with systemd. However, this must first be adapted to the local conditions.

Copy the file ../vimon/services/vimon.service into the directory /etc/systemd/system.
Activate Service.
sudo systemctl enable vimon.service

init.d

The Service services/monitoringservice can be integrated with init.d.

Rotating and compressing the log files

In addition, logrotate can be used under Linux to rotate and compress the log files. There is a template for this in the VIMON base bundle at vimon/config/logrotate.d/vimon This can be copied to /etc/logrotate.d/.

In addition, the base directory may need to be adapted in the copied template.

Setting up Services under Windows

There are installation scripts for Windows at services/install for setting up the services. The Services can be set up/removed/edited with the following commands:

Execute the command prompt (cmd) as administrator.

Grafana:

grafana install

Set up service

grafana uninstall

Remove service

grafana manage

Check/manually edit service
Prometheus:

prometheus install

Set up service

prometheus uninstall

Remove service

prometheus manage

Check/manually edit service
Loki:

loki install

Set up service

loki uninstall

Remove service

loki manage

Check/manually edit
Exporter:

The exporters are managed via a consolidated script exporter. This expects an additional Parameter with the respective exporter.
If the script is executed without Parameters (i.e. simply exporter), it recognizes all available exporters and outputs their names:
```
c:\virtimo\vimon\services\install>exporter
Usage: exporter <Install,Uninstall,Manage> <Exporter_Name>
List of available exporter_names:
blackbox_exporter
diskbench_exporter
isdb_exporter
promtail
windows_exporter
```
It can then be used in the same way as the others, e.g. for the Windows exporter:

exporter install windows_exporter

Set up service

exporter uninstall windows_exporter

Remove service

exporter manage windows_exporter

Check/manually edit service

Now you can start, stop, activate and deactivate the Services via Windows Services Management.

Before the service can be started, it usually has to be configured first.
