Room For Improvement

PRTG Network Monitor requires enhancements in performance, cloud integration, user interface, and affordability to meet user demands effectively.

PRTG Network Monitor should provide syslog monitoring since it is not available at this time.
They need to improve application performance monitoring, error tracing mechanisms, and log management.
They previously had a perpetual model, which meant that you bought a license and if you missed the end of the time, it still worked; you just lost the possibility of some upgrades.
The only issue I can note is that it's Linux-based, and Linux documentation is not the best.

Zabbix is cost-effective and flexible, offering open-source monitoring with no licensing fees, low expenses, and optional support costs.
It's not too high, nor too low, but it's reasonable.
Pricing is by the number of devices, not by sensor.
The prices are very high for PRTG Network Monitor.

It is advantageous because it can be deployed on-premises.
The pricing is affordable compared to SolarWinds.
If disk usage surpasses a threshold, say 70%, I receive alerts and can take proactive action.
Zabbix is Linux-based open-source software, and the main use case is to reduce costs.
Zabbix has a lot of features, including monitoring, status updates, and collecting information telemetry from storages and servers as well.
