Effective alerting enhances network monitoring experience with an easy setup
We love Nagios XI due to the fact that JPS Web is very useful. JPS monitors the modem and performs switching, monitoring the computer, and performing switching. 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.
Lakshmi Padaga - PeerSpot reviewer
Collaborates performance metrics with log data to pinpoint the exact cause of issues and offers error detection
Splunk APM is a robust tool with many capabilities. There are always areas for potential improvement to enhance its functionality and user experience. For Splunk APM, there could be simplified navigation, like streamlining the user interface to make navigation more intuitive for our users, especially those new to APM, which can enhance usability. We can provide more customization options for dashboards and visualizations to help users tailor the platform to their specific needs. There could be more integration capabilities with a wider range of third-party tools and platforms would also be beneficial. By focusing on these areas, Splunk APM can enhance its value proposition, improve user satisfaction, and better meet the evolving needs of organizations monitoring their application performance.
