Requirements
In order to install a panagenda product on a existing appliance, the following requirements must be met:
Software Dependencies
- Docker version >= 19.03 (https://docs.docker.com/install/)
- Docker Compose version >= 1.21 (https://docs.docker.com/compose/install/)
- unzip (to extract the installer from our zip file)
Partitions
Our software needs a second virtual disk to store its data. Therefore you need to add a second 100 GB virtual disk to the virtual machine using vSphere and restart the virtual machine.
Afterwards please create the following volumes:
| Volume | Mount point | Size |
|---|---|---|
| cl-pan-opt_panagenda_logs | /opt/panagenda/logs | 5GB |
| cl-pan-opt_panagenda_appdata | /opt/panagenda/appdata | 30GB |
| cl-pan-opt_panagenda_pgdata | /opt/panagenda/pgdata | at least 60GB Additional resources may be required under all above described conditions, depending on data collection intervals, number of sensors enabled, and number of servers being monitored. panagenda and selected panagenda OfficeExpert business partners can help you evaluate the optimum hardware specifications for your environment. |
The naming of the volumes is important because the software will use the names to check the disk usage to prevent data corruption!
Technical Support
To facilitate technical support you should also install:
- A graphical user interface (e.g. GNOME)
- A terminal (e.g. GNOME Terminal)
- A browser (e.g. Firefox)
- pgAdmin (https://www.pgadmin.org/download/)
Example for CentOS 7
We tested the following commands to install the requirements on a CentOS 7.7 server. They should also work for RHEL 7.
In our case the device name of the data disk was /dev/sdb. This might be different in your scenario. The following command can be used to determine yours:
ls /dev/sd*
Afterwards please adapt the pvcreate and vgcreate commands.
