50 Top Server Monitoring & Application Monitoring Tools

Back in 2014, I compiled a list of top server and application performance monitoring solutions. Sharing that list publicly was a great way to gain feedback and recommendations on other tools available. In time that list grew from 20 to over 100 server monitoring and APM solutions! Because of its growing size, I’ve created below, a smaller, more focused list of 50 recommended APM and/or server monitoring solutions.

The intention of this list is to allow you to easily investigate and find your best set of tools. Some of those listed such as Solarwinds, Datadog, NewRelic, Stacify, Cacti, Nagios, etc. …I’ve used at some point over the past decade. As always, please share your comments and suggestions with me below or by email.


I’ve created below, a second, smaller list which includes…
50 select Server and Application Performance Monitoring solutions.

    Sysdig has an open source troubleshooting component that allows users to go all the way down to system call and process payload that’s integrated into our monitoring offering or can be used as a killer stand-alone monitoring tool.

  20. Also worth checking out is CronAlarm – https://www.cronalarm.com. Useful for monitoring cron jobs and scheduled tasks. It monitors for runtime errors, silent failures, etc.

  24. I often use UptimeRobot and StatusCake but recently I started using CULA. It’s a fairy new tool, I found it on alternativeto. It looks good and doesn’t cost me anything.

  31. What about the tool we use: CloudView NMS http://www.cloudviewnms.com . It can monitor pretty much anything plugged into your network or public Internet.
    Network Monitoring: switches, routers, firewalls, mobile devices, any other network devices, availability (health, up-time, OK status). Unlimited number of free SNMP probes (you can either compile private MIBs or using raw SNMP OIDs). They do not charge per network size. Server Monitoring: CPU Load, Memory Usage, Disk Usage, Bandwidth, Cloud Services, Web Page/Site, Layer-7 services (SQL,SSH, FTP, HTTP/HTTPS….). Both agent-less and agent-oriented monitoring is available. Applications monitoring,Quality of Service monitoring, Service Level Agreement (SLA) monitoring. Environment monitoring: temperature, humidity, etc…, SCADA devices monitoring.

  33. I did not see it in the list, but Probeturion is the best tool/system for monitoring anything within a LAN that I have ever used. It is free until a certain amount of sensors. This let any IT operational test it for free without any commitments. The system is quite new, but it is their 4th generation of monitoring system. These people have been in the game for about 20 years and know exactly what is missing. It is not free if a company want to use it for many sensors, and the price is high. This is because they deliver. Probeturion is the Rolls Royce of IT infrastructure monitoring.

  34. We use Probeturion at http://www.probeturion.com. This system comes with new features as it is a factory. Support is above and beyond great, and it is just getting better and better. The way they think and innovate are brilliant.
