The aim is to replace Opsview that is used to monitor all systems and related processes in the company as it does not meet now-a-days requirements:
- PostgreSQL backend
- Automated deployment (e.g. Puppet)
- Nagios plugins
Googling: monitoring open source linux systems results in:
- Top 5 best system monitoring tools: nagios, cacti, top, zabbix, munin
- zenoss core
- Opsview core
The expectation was that Googling would indicate whether one of the software packages meets the demands as defined in the aim paragraph.
Opsview core will not be an option as it seems to be restricted to a MySQL backed. Nagios is not an option as well as this is used by Opsview and seems to be restricted to MySQL as well.
Although Zabbix can run on a PostgreSQL backend it seems not to be fully automated.
