Reporting features improve operational efficiency while weekend support needs enhancement
Support is moderate and needs improvement, especially during weekends when technicians perform upgrades. During weekends, they need to provide more support to ensure a smooth transition.

Although the product stability is good, support enhancement is necessary to enable better planning for upgrades and maintenance activities.

We implement some applications and traffic monitoring. The alerting system is very effective. For instance, if we have an alarm on some RAM storage if the traffic is cut or dropped.
