Dimensioning virtual machines
Introduction
We recommend the following virtual machine sizes:
For nGeniusPULSE without SNMP polling (only synthetic testing): model J
For nGeniusPULSE including SNMP polling: model K
For nGeniusPULSE including SNMP polling > 2000 objects: model M
Solution
nGeniusPulse Small System
This deployment has been tested in situations where there are less than 50 nPoints and no infrastructure monitoring.
All appliances are installed from an iso-file provided by COMCERT at the day of installation.
| Virtual Machine Settings | nGeniusPULSE Server |
|---|---|
| Type | J |
| CPU | 4 |
| Memory | 48GB |
| Network adapter 1 | 1x VMXNET3 |
| Hard disk 1 (see 1) | 86GB |
| Hard disk 2 (see 1) | 12GB |
| Hard disk 3 (see 1) | 64GB |
| SCSI controller (see 2) | LSI Logic Parallel |
| Guest OS (see 3) | CentOS 7 |
(1) It is important to respect the order and sizes of the hard disk. All hard disks can be thin provisioned. Disk 2 and 3 performace must have no less than 300 IOPS; choose your datastore accordingly.
(2) Recommended.
(3) For information only; the operarating system is part of the iso and will be installed with the software.
nGeniusPULSE Medium System
This deployment has been tested in situations where there are less than 250 nPoints and less than 2500 monitorred elements.
All appliances are installed from an iso-file provided by COMCERT at the day of installation.
